Highly Pathogenic Avian Influenza (HPAI) News

Iowa Farmer Battles Today's Pests While Eyeing Tomorrow's 'Mean Sixteen' Threats

Fri, 12 Dec 2025 19:31:41 GMT

For Worth County, Iowa, farmer Sarah Tweeten, the list of high-priority agronomic threats isn’t a political abstract — it’s a harsh reality she deals with every season.

Farming with her parents, Brian and Julie, and her uncle Roger, Tweeten has been steering the partnership toward more resilient cropping practices since joining the operation in 2021. This includes shifting from conventional tillage to strip tillage and splitting nitrogen applications.

The changes are part of a broader mindset: Protecting yields today from weeds, disease and insects while aggressively preparing for the next generation of agronomic threats. This forward-thinking approach is what led Tweeten to Washington, D.C., earlier this week as a Farm Journal Foundation farmer ambassador to help introduce a new report: “ The Mean Sixteen: Major Biosecurity Threats Facing U.S. Agriculture and How Policy Solutions Can Help. ”

Today’s Battles and Tomorrow’s Warnings
Researched and developed by Stephanie Mercier, PhD, the report takes an in-depth look at 16 significant pest issues U.S. farmers face now or could realistically in the future.

Tweeten is already battling a couple of the problems that underpin the urgency behind the research. For example, Palmer amaranth (pigweed) is gaining ground in her fields and across Iowa. The pervasive broadleaf weed can drastically reduce yields, with studies showing corn yield reductions between 11% and 91% and soybean yield reductions of 17% to 68%.

“We’ve struggled with pigweed as it continues to establish more resistance to our herbicides in our toolkit,” Tweeten says.

Two additional agronomic issues the report details include:

1. Asian Soybean Rust. First detected in the U.S. in Louisiana in 2004, this fungal disease has spread to southern states like Georgia and Mississippi. Scientists warn that warming winters could enable its migration to the Midwest, adding to existing disease pressures.

2. Corn Ear Rot. It can lead to aflatoxin production, making corn unmarketable and posing risks to humans and livestock. Aflatoxin is an issue Pickens County, Ala., farmer Annie Dee says is an ongoing problem for corn growers in her area.

“If we have aflatoxin, it can be impossible to sell the corn,” says Dee, also a Farm Journal Foundation Farmer ambassador.

A more recent threat she references is the impact of Highly Pathogenic Avian Influenza (bird flu) on local poultry farms.

Since January 2022, HPAI has been confirmed in a commercial or backyard poultry flock in all 50 states.

“An important market for us is poultry feed meal, so that’s a constant worry. The trickle-down effect is if we can’t move our corn then we can’t meet our financial obligations,” Dee adds.

Despite agricultural R&D offering a high ROI — $20 in benefits for every $1 spent — the Farm Journal Foundation report notes public funding for ag research has been declining over the past two decades.

“Farmers urgently need sustained support for aflatoxin research and prevention because these risks threaten our yields, our markets and the trust consumers place in American agriculture,” Dee says.

U.S. public spending on ag research and development has been falling for two decades.

African Swine Fever Has ‘Devastating Potential’
Looking to the future, Tweeten says she is concerned about African swine fever (ASF) and its potential to impact crop farmers as well as hog producers. The highly contagious swine disease hasn’t been detected in the U.S. mainland, but it isn’t far away. ASF has been confirmed in the Caribbean countries of Haiti and the Dominican Republic, roughly 700 miles from Miami, Fla.

“Being a farmer from Iowa, where we have probably eight times the amount of pigs as we do people, an outbreak of ASF would be just devastating to our state,” Tweeten says.

Hogs are among the biggest customers for the corn and soybeans Tweeten and her family grow. If African swine fever were to shut down hog production or exports, it wouldn’t just be a blow to livestock producers – it would hurt the entire agricultural community, she contends.

Food Security Is National Security
When it comes to justifying funding for ag research, Tweeten knows there’s competition for every federal dollar. But she believes agriculture deserves a front-row seat — not only because of its economic weight and impact on farmers, but because of its role in national security.

“There’s that argument that food security is national security,” she says. “If there’s one thing COVID made us aware of, it’s that a disruption to our food chain can be terrifying, quite frankly.”

The pandemic made consumers and policymakers more aware of supply chain vulnerability. In 2020, the shock to the supply chain came from a human disease and logistical bottlenecks.

Next time, Tweeten says, the disruption could just as easily come from animal or plant disease — whether African swine fever in hogs, Asian soybean rust or some other pathogen in crops. She worries about scenarios where farmers could face a fast-moving disease or crop pest while critical tools are still hung up in regulatory delays.

Her message: Farmers need a full toolbox, not one that’s half-built by the time a threat arrives.

“Ag needs to be in a good position when these sorts of emerging diseases and pests come into the country,” she says, “to have the tools in our toolbox ready for farmers to pull out.”

Why We're Seeing More Bird Flu Infections Earlier

Tue, 18 Nov 2025 16:27:50 GMT

According to the USDA-APHIS dashboard , there have been 36 commercial flocks of poultry infected with highly pathogenic avian influenza (HPAI) in the past 30 days. Including backyard flocks, it totals more than 1.8 million birds.

Rebecca Eifert Joniskan, president of the Indiana State Poultry Association, says the disease has arrived earlier than “usual” as wild birds spread the virus with their seasonal migration patterns.

“We typically don’t see avian influenza until January or February,” she says. “This year we started October 9.”

Matt Makens of Makens Weather says weather patterns play a role in bird movement, and therefore virus transmission.

“In winters like this. our temperatures will be very volatile. There’ll be swings of very, very warm days. And then very, very cold days. And I think there is a connection to bird flu spread in those warmer periods,” he says.

Indiana is a poultry powerhouse for commercial production, ranking No. 1 in duck (60% of the U.S. duck produced), No. 3 in eggs, No. 4 in turkey, and a large-scale epicenter for broiler production as well.

While HPAI has been a renewed biosecurity concern for poultry since Feb. 2022, the infection has set into a seasonal pattern—creating some predictability. However, the early onset of birds being infected this fall has Joniskan and industry members concerned a long and difficult season is ahead.

“Typically, it fades over the summer. The virus burns itself out with birds in the Arctic,” she says. “That hasn’t been happening. The virus isn’t following the rules. It’s back, and it’s early.”

The first infections in Indiana were in northern countries and affected ducks and free-range egg layers. Currently, Indiana has the most reports of HPAI infection in commercial and backyard flocks for the past 30 days.

States reporting recent infections in commercial flocks are: California, Georgia, Indiana, Michigan, Minnesota, North Dakota, and South Dakota.
The past decade has brought an increased focus on biosecurity and disease prevention.

“When we had avian influenza in 2015 and 2016, there were a lot of learnings on how to reduce the risk of introduction of the virus on your farm,” she explains. “There were changes put in place, including annual biosecurity reviews.”

She says poultry producers in Indiana have taken the virus risk seriously and are actively preventing its introduction while also being ready to respond to it.

“Our companies across the state have taken the learning from ‘15/’16 and what we’ve learned since 2022, and they’ve doubled down to try to reduce any opportunity for introduction wherever they can. It’s difficult, but it’s less expensive and trying than the dealing with an infection,” she says.

Once a flock is infected, the birds don’t recover from the virus, and depopulation is the end result.

Veterinarian Becomes Disease Detective: Nichols Connects Animal Disease and Human Health

Tue, 07 Oct 2025 19:26:37 GMT

Growing up on a New Mexico ranch, veterinarian and public health leader Megin Nichols says she learned early the health of animals, humans and the environment are deeply connected.

Initially planning to practice small animal medicine, she says her plans began to pivot when she met a Centers for Disease Control and Prevention (CDC) epidemic intelligence service officer who sparked her interest in public health. That realization led her to pursue a master’s degree in public health at the University of Minnesota, with a focus on food safety and biosecurity. Her career has included roles in local, state and federal health departments, investigating foodborne illness outbreaks and developing strategies to prevent them.

“Life has a way of taking you in places you never anticipated,” she shared during the 2025 Henry C. Gardiner Global Food Systems Lecture Oct. 6 at Kansas State University.

Today, as the CDC’s director in the division of foodborne, waterborne and environmental diseases, she lends her expertise to efforts involving disease investigation, food safety, antimicrobial resistance and agriculture literacy.

Megin Nichols has more than 15 years of zoonotic disease experience and has served at the federal and state levels. She has served as the lead of the Enteric Zoonoses Team investigating multistate outbreaks of Salmonella and E. coli. Prior to joining CDC, Nichols worked as the Principal Investigator of the Active Bacterial Core Surveillance Program at the New Mexico Department of Health for five years.

One Health: Connecting Animal Disease and Human Health

Nichols’ work focuses on the One Health concept.

“One Health is recognizing the health and well-being of humans, of animals and our environment are all interconnected,” she explains. “One Health is something that many of us do every single day and are very, very aware of, especially if you have ties to agriculture and the land. But One Health as a concept oftentimes is difficult to fully understand.”

Nichols says One Health is:

Ongoing relationships with animal agencies.
Understand the culture of agriculture.
Having access to integrated human and animal surveillance.
Protocols for conducting joint response investigations.
Agreements for sharing biological samples and lab results.
Established lines of communication with agriculture and animal industry.
Plans for unified communication messaging.
Need to build linkages and trust before and outbreak.

“What happens in one area can significantly impact others — whether it’s a wildfire, a disease outbreak or environmental changes,” Nichols summarizes.

Pandemic and Disease Response Insights

Nichols was a leader in investigating and finding unique solutions for the livestock industry and specifically meat packing industry related to COVID-19.

“In April 2020, I got a call from my supervisor saying there are some meat, poultry packing plants that are going down because of labor shortages and illness,” she explains.

She selected and lead a team to figure out how to get the plants opened back up safely and to find unique solution to deal with the related animal welfare issues.

Summarizing the experiences, Nichols reports the estimated economic cost of COVID-19 is $14 trillion. Along with supply chain disruptions the industry experienced changes in consumer behavior, labor shortage and complex operations challenges. On a positive note, she says the industry did experience a lot of innovation and uptake of technology due to the pandemic, which resulted in innovative approaches to workplace safety and communication.

“We saw innovative strategies where if one person got sick, they looked around that worker and said, ‘OK, who do we need to monitor quickly for symptoms?’” she says.

Nichols also discussed the increase in salmonella outbreaks during the pandemic. She links the rise to the increase in backyard poultry ownership and the improper handling of backyard chickens.

“Many new chicken owners were unaware of disease transmission risks,” she explains.

Nichols also shared insights to H5N1 influenza and emphasized the complexity of tracking and preventing. She highlights the need for integrated, cross-species surveillance and communication strategies.

She also touched on emerging threats, including New World screwworm (NWS) . Her message emphasized the importance of prevention, control and preparedness.

She shares these five key strategies related to NWS:

Surveillance. Early dection through wound inspections and reporting in livestock.
Sterile Insect Technique (SIT). Ongoing release of serile male flies to prevent reproduction.
Biosecurity. Movement control of imported animals and monitoring at entry points.
Public Awareness. Education for doctors, ranchers, veterinarians and travelers.
Rapid Response Planning. Multi-agency coordination to contain outbreaks swiftly and deploy sterile flies.

Agricultural Literacy, Communication is Key

“Growing up in the middle of nowhere, I also came to understand that not everyone appreciates — or even understands — where their food comes from,” Nichols says.

She shared a 1993 study that revealed significant gaps in public knowledge about agriculture. She summarizes understanding food systems involves knowing:

Where food comes from.
How it’s produced.
Its impact on economy, environment and technology.

Throughout her lecture she shared the importance of transforming complex scientific concepts into engaging, accessible insights that resonate with students, farmers, ranchers and public health professionals alike.

“It doesn’t matter how much information we have if we don’t get it out to the people,” Nichols says.

She stresses the importance of agricultural communication specialists in translating scientific information and engaging audiences.

“Don’t leave the communications to the scientists,” she says.

Nichols emphasizes that agricultural literacy and effective communication are crucial for bridging knowledge gaps and building public understanding of food systems.

She shares this advice for agricultural advocates:

Bring agricultural perspective to discussions by speaking up and sharing lived experiences.
Challenge misconceptions with personal stories by focusing on storytelling rather than technical details.
Understand your audience and use relatable language and provide context.

Nichols stresses the importance of preparedness and collaboration. She explains the importance of local-level discussions and community preparedness, suggesting that some of the most effective emergency preparedness conversations happen “at the coffee house” or during casual community gatherings.

10 H5N1 Risk to Swine Projects Receive Funding to Address Emerging Disease Threat

Wed, 23 Jul 2025 01:58:49 GMT

The Swine Health Information Center, in collaboration with the Foundation for Food & Agriculture Research and the Pork Checkoff, has recently funded 10 projects addressing research priorities and topics within its H5N1 Risk to Swine Research Program. Goals of the program are to enhance prevention, preparedness, mitigation, and response capabilities for H5N1 influenza in the U.S. swine herd. The priority areas addressed through the funded projects include vaccine development and cross-protection, clinical presentation of pigs across different production phases, potential for mammary transmission, diagnostic surveillance, introduction and transmission risks, and biosecurity practices. The 10 new projects were initiated in summer 2025 and are 12 to 18 months in duration. Research outcomes from the funded projects will be shared with producers and veterinarians as soon as they become available.

The SHIC/FFAR/NPB H5N1 Risk to Swine Research Program request for proposals was announced on November 6, 2024, and received 51 proposals from 35 different institutions across six countries by the submission deadline of December 31, 2024. Proposals underwent a competitive review process across the first several months of 2025 by subject matter experts on influenza and the swine industry. Funding awarded across the 10 new projects totals $2.1 million of the $4 million total available for this collaborative research program. Funding timely research is an essential component of SHIC providing project outcomes that drive action for emerging disease prevention, preparedness, mitigation, and response for the US swine industry.

SHIC/FFAR/NPB H5N1 Risk to Swine Research Program projects funded and initiated in response to the RFP include:

Outcomes from the funded projects will provide critical information that producers, veterinarians, and industry stakeholders can use to better prevent incursion and develop preparedness plans if H5N1 is identified in U.S. commercial swine herds.

H5N1 Update: New Research Projects Will Explore H5N1 Risk to Swine

Mon, 23 Jun 2025 14:24:27 GMT

When highly pathogenic avian influenza (H5N1) struck the U.S. dairy industry in March 2024, the swine industry kept a close eye on what was unfolding to better understand potential introduction into swine.

“We really wanted to take a proactive approach from the swine industry’s perspective on understanding what this would look like in pigs,” says Megan Niederwerder, executive director of the Swine Health Information Center (SHIC). “Would it look like endemic influenza? What would be the clinical response? Could it cause mastitis in our sow farms, or would it be a high mortality incident similar to poultry with significant death loss and severe disease?”

Although there was a single case in backyard swine in Oregon in October of 2024, the pigs never had clinical signs, she explains.

“These were outdoor, backyard raised pigs that were never intended for the food supply, they did not show clinical signs, and they were exposed due to co-housing with poultry that were infected,” Niederwerder says. “Because of that, we wanted to look at the risk factors for introduction into commercial swine. How can we prevent it? How can we mitigate it? How can we be prepared so we can inform producers and veterinarians what to look for, how to collect samples and how to detect it?”

Investing in Answers
One of the efforts of SHIC was to form the H5N1 Risk to Swine Research Program, along with the Pork Checkoff and the Foundation for Food & Agriculture Research. Producers, veterinarians and other key stakeholders within the swine industry helped to identify gaps in knowledge and develop the research priorities. Through this total investment of $4 million, the organizations received a total of 51 proposals. These proposals went through a competitive peer review process during the first several months of 2025, Niederwerder explains.

The program has recently selected 10 projects for funding, with about $2.1 million going toward universities and companies to conduct this research trying to answer those questions about clinical presentation of the virus in swine in various groups.

“Whether that be sows, suckling pigs, nursery pigs, or grow-finish pigs, this research will look at the different clinical presentations, including from a mammary transmission understanding,” she says. “In addition, researchers will work on studies to discover if H5N1 could impact milk production in sows and biosecurity practices that would reduce the risk from wild birds and other wildlife that may be infected with H5N1.”

As well, these projects will further knowledge of the best diagnostic surveillance tools for early detection and better understand the potential for incursion.

“It’s important we consider the H5N1 risk learnings from the dairy industry and the poultry industry,” she says. “Then, we will apply those learnings to the unique characteristics of the swine industry to hopefully prevent any incursion in the commercial swine herd. We continue to look for other opportunities as well to generate knowledge and tools for our producers.”

Niederwerder says SHIC plans to release the funded projects soon.

How is the U.S. Swine Industry Staying A Step Ahead When It Comes to Swine Health?

Tue, 17 Jun 2025 19:07:28 GMT

Keeping one step ahead of the health of the U.S. swine herd is no easy task. Anna Forseth, DVM, National Pork Producers Council (NPPC) director of animal health, says developing a highly pathogenic avian influenza (H5N1) response plan for the swine industry and establishing the National Swine Health Strategy have been two major priorities this year.

H5N1 Response Plan
“We’ve been watching the devastation of H5N1 in the poultry sector, and more recently, the detection of H5N1 in the dairy industry,” Forseth says. “And all the while thinking, how might this impact the swine industry should we get a detection, especially in the commercial swine sector?”

The differing responses in the poultry and dairy industries to the same virus have a lot to do with how the virus is regulated for those two different species. There are attributes of the response in both sectors that just would not work well in the swine industry, she explains.

The U.S. swine industry convened a small group of the national organizations, state veterinarians, state associations and producers to draft a guidance response plan should the H5N1 virus get into the commercial swine herd. Forseth says the focus of this guidance is really on business continuity opportunities.

“Let’s use the example of a sow farm. If a sow farm were to get infected with H5N1, especially in the absence of a vaccine, it would be really challenging to eradicate the virus in the short term,” Forseth says. “What can be done to allow for those pigs to be weaned from that farm until that farm can get to a point where they’re stable or eradicate the virus?”

She says much of the plan focuses on sidebars like increased biosecurity, movement controls and surveillance to try to reduce the risk that they’ll continue to spread the virus, but still allows them to move pigs off that farm.

The response plan was submitted to USDA in late January. USDA is also working on their own guidance response plan, she notes.

“We have been in conversation with USDA about what a potential response may look like,” Forseth says. “I think over the next few months we’ll have some additional conversations where we can address areas of the plans that don’t necessarily match right now.”

National Swine Health Strategy
African swine fever prevention and preparedness efforts have been a focus for several years now. Forseth says the pork industry decided it was time to revisit priorities to ensure they best fit the current situation.

“We decided we should expand the scope,” she says. “Initially we were planning to expand it to the other two foreign swine diseases. But given the feedback we’ve received from producers over the last two years, with a lot of emphasis on endemic diseases, we decided to initiate the development of a National Swine Health Strategy.”

The strategy is being led by the National Pork Board. During the next few months, Forseth says they will talk with producers and ask a simple question: What are your current challenges or concerns?

“We are asking them to provide one to three examples,” she says. “Then, they have an opportunity to expand on how they think we as national organizations, research institutions, state associations, etc. could help them address those challenges.”

An industry advisory group will come together later this summer to compile and evaluate the feedback and then redefine or establish a new set of priorities. Forseth says she expects they will be a combination of endemic health challenges and foreign disease priorities.

“There’s also a possibility that there are some priorities that don’t have anything to do with disease,” she points out. “Specifically, we might talk about nutrition, biotech or labor. We’ll see what comes out of some of those listening sessions and a producer survey that will be out for the next several weeks.”

At the end of the day, the National Swine Health Strategy is meant to reestablish swine health priorities that will be shared more broadly.

“It’s not just going to be kept with the national organizations,” Forseth says. “We’ll share it with academic institutions, with USDA Agricultural Research Service, and really any other entity that works in the area of swine health. The goal is for everyone to be focusing on the producers’ needs.”

EU Halts Brazil Poultry and Meat Imports After HPAI Outbreak

Mon, 19 May 2025 15:55:03 GMT

Brazil, the world’s largest poultry exporter and main poultry meat importer into the European Union, is no longer allowed to ship poultry and meat products to the EU due to the recent outbreak of highly pathogenic avian influenza (HPAI).

Brazil confirmed the country’s first HPAI outbreak on a commercial farm in the southern state of Rio Grande do Sul on May 16.

The entire territory of Brazil has suspended its official status of being “free of highly pathogenic avian influenza.” The EU joins with bans from top buyer China, Reuters reported. According to a European Commission spokesperson, EU import conditions require that the country of export (Brazil) is free of HPAI.

Why do U.S. farmers need to pay attention?

There are two reasons for U.S. farmers to be watching the developments of the disease and its effect on the Brazilian poultry industry.

Dan Basse, AgResource Company, says Brazil poultry exports account for about 33% of the global poultry supply.

“A good portion of that goes to China,” Basse says. “The Chinese are out and already saying that they are going to be restricting Brazilian poultry but, we’ll see. The Chinese took last year about 570,000 tons of Brazilian product. I don’t know where they would replace it–but they’re not going to do it from the United States with the trade war.”

He says another reason to watch is the feed side of the Brazilian poultry flock.

“Those birds consume a lot of meal and a lot of corn, it’s like 17.6 million metric tons of Brazilian meal, and 42 to 43 million tons of corn,” Basse says. “So we’ve got to think about this not only from a export opportunity for US poultry, but from a demand concern of what the Brazilians will do in terms of feed consumption. They’ll become more aggressive in offering meal and corn to the world market if flocks down there do need to be depopulated and are starting over.”

What are teh next steps?

Restriction on poultry exports follows rules agreed on with each importing country, based on international health certificate requirements, the Agriculture and Livestock ministry told the Associated Press (AP). Depending on the type of the disease, some deals apply to the whole country while others involve limits on where products can come from — for example, a specific state, city or just the area of the outbreak.

Countries like Japan, Saudi Arabia, the United Arab Emirates and the Philippines have already accepted this regional approach, AP reported.

Brazil exported more than 5 million tons of poultry meat in 2024. Reuters reported that approximately 4.4% headed to the EU. Of total EU poultry imports, Brazil is the main origin with a share of 32% last year, according to official EU data.

The U.S. bird flu outbreak and wider trade tensions with Washington have limited Chinese appetite for American poultry. China now blocks poultry from more than 40 U.S. states over HPAI, according to U.S. government data, Reuters reported .

If the HPAI outbreak spreads across Brazil, as it did in the U.S., officials and analysts said outlooks could get dimmer, Reuters reported. That scenario would raise U.S. hopes for China to ease restrictions on American poultry.

Under a Phase 1 trade agreement China signed with U.S. President Donald Trump during his first term in 2020, China is supposed to lift statewide bans on U.S. poultry 90 days after states eliminate bird flu from infected farms.

However, China has kept bans in place longer than it had agreed in that deal, according to the article.

Greg Tyler, CEO of the USA Poultry and Egg Export Council industry group, told Reuters he is hopeful China will move back to abiding by that regionalization agreement.

Don't Be Deceived: Wildlife Pose Serious Threat to Livestock Producers

Tue, 01 Apr 2025 13:42:17 GMT

At first glance, the house sparrow may not seem all that intimidating. But now that highly pathogenic avian influenza (HPAI) is endemic in the wildlife waterfowl population, this tiny bird could become a huge problem for U.S. livestock producers, USDA’s David Marks said at the 2025 American Association of Swine Veterinarians annual meeting in San Francisco in March.

“Ducks and geese waterfowl are a reservoir for highly pathogenic avian influenza (HPAI),” says Marks who serves on the staff of USDA Animal and Plant Health Inspection Services (APHIS) Wildlife Services (WS). “They brought it over here in 2022 from Europe and Asia, and now it is circulating in waterfowl. HPAI is a foreign animal disease in North and North America, but now it’s endemic in wildlife. It’s not a good situation.”

Peri-domestic birds like the house sparrow and the American robin are attracted to the same water sources as these ducks and geese, which can result in peri-domestic birds carrying the disease back to the livestock barns, Marks explains.

“Keep your farms tight,” he says. “HPAI is mixing and reassorting in our waterfowl. Every time it gets in these birds, it’s mutating. Over 85% of positive farms now are from wildlife introductions.”

When it comes to managing wildlife disease threats, there are basically three options: manage the site itself, manage the wildlife, or install a barrier to keep wildlife out.

How Big of a Problem Do We Have?
Since the outbreak in poultry in 2022, APHIS has worked with state animal health officials to identify and respond to detections and mitigate the virus’ impact on U.S. poultry production and trade. Marks says more than 105.2 million birds in 1,197 flocks in 48 states have been affected by the virus since then. In response to this current outbreak, USDA has spent over $1 billion, paying for indemnity, cleanup and disinfection of facilities, diagnostics and other aspects related emergency response.

“More than 75% of infections have been directly related to new introductions of virus of wildlife origin and not related to lateral transfer between facilities, employees and equipment as in previous HPAI outbreaks,” Marks says.

WS developed the Midwest Wildlife Biosecurity Assessment Pilot Project in response to the continued outbreaks of HPAI across the country. Four states (Iowa, Minnesota, North Dakota and South Dakota) were selected as the focus for this project based upon the high number of infections and re-introductions of facilities during calendar year 2022 from within this area.

Earlier this month, USDA announced it is expanding the availability of its biosecurity assessments to commercial poultry producers.

“These assessments, which were previously available on a limited basis have been extremely successful in improving biosecurity on individual premises and preventing the introduction or spread of avian influenza,” USDA Secretary Brooke Rollins said.

The goal of the assessments is to take a proactive approach to managing potential disease transfer and improve the wildlife biosecurity of commercial poultry facilities in the U.S., thus reducing the number of facilities that become infected with HPAI and other diseases of concern to the poultry industry, Marks explains.

Wildlife biosecurity assessments are through evaluations of all buildings, external operations and wildlife population use and movements that occur on and near commercial poultry facilities. These reports are directly provided to facility managers and include long-term management recommendations for mitigating any identified risks related to wildlife.

The formal WBA process is comprised of three main components: Wildlife hazard identification surveys, wildlife abundance surveys, and in most cases, direct control and continued monitoring for attractants, hazards, and wildlife.

Step 1: Wildlife Abundance Surveys
What species are there in the first place? Marks says wildlife abundance surveys (WAS) simply determine what wildlife species one could expect and that one finds on an operation.

“A farm in northwest Iowa might be different than a farm in southeast Iowa or Texas,” he points out. “WS conducts WAS at different times during the day (morning, midday, evening, and night) to understand the different species present in and around the facilities at these times.”

After establishing multiple survey points to represent all habitats and cover the perimeter, WS conducts standardized wildlife point counts at each survey point and revisits those monthly to create population trend data. These maps show areas of wildlife activity for each facility.

Step 2: Wildlife Hazard Identification Surveys
Wildlife hazard identification survey (WHIS) take place at all facilities as they enter the program, he says. These reports provide a detailed list of all the wildlife biosecurity hazards found within the perimeter buffer area of the facility, and categorizes hazards into three tiers, with tier 1 being of the greatest concern. Examples of Tier 1 hazards include holes in barn exterior walls, exclusionary netting, or other breaches that would allow direct contact with wildlife and poultry.

Lower Tier hazards include wildlife attractants and potential sources for indirect transmission routes, such as standing water and food sources. WS conducts the first WHIS during an initial facility site visit and generates the report for the producer shortly after. WHIS reports contain photographs of all hazards identified and their locations represented on an aerial photo. WS designs the reports so producers can quickly identify and mitigate any hazards found.

WS personnel conduct subsequent WHIS quarterly to monitor progress. They also monitor for additional hazards continuously while on site, and any additional hazards found are recorded and relayed to producers in real time. Formal quarterly WHIS reports help track hazards and mitigation over time.

Step 3: Direct Control
The next step is to develop a plan for routine direct control actions. This includes both lethal (removal) and nonlethal (habitat management, exclusion, harassment) management of wildlife present at the facility, Marks explains.

“WS records all direct control activity results, along with wildlife observations while on site,” he says. “These are not standardized data, but over time are very valuable in showing trends and we expect a direct inverse correlation to result from wildlife abundance surveys (ie, the more wildlife managed, the lower the wildlife abundance on site). Similar to wildlife abundance data, direct control trend data can be depicted on a map of a facility to show areas of wildlife activity.”

After the first six months of participation in the program, WS generates a comprehensive report for the facility, which summarizes all WS personnel activities.

While on site, WS personnel collect samples from wildlife species for HPAI testing, he adds. Sampling strategies focus on facilities that have recently become positive for HPAI because of the increased likelihood of the virus being present in non-reservoir species. WS processes samples and submits them to the diagnostic lab for analysis, and all influenza A detections are forwarded to the USDA National Veterinary Services Laboratory for confirmation and genomic sequencing. Additionally, WS collects samples from a subset of wildlife collected from non-infected facilities.

What Can You Do Now?
Although the biosecurity assessments and audits are offered to poultry producers only at this time, WS does offer financial support to help dairy producers enhance biosecurity and offset costs associated with Influenza A testing, veterinary expenses, personal protective equipment purchases, milk disposal and milk losses.

“The wildlife exclusions and barn setups are similar between swine and poultry facilities,” Marks says. “Biosecurity is a critical tool for disease prevention for all species.”

USDA encourages all producers to review their biosecurity plans and take action now to prevent disease from reaching their herds. While the actual assessments may not be available to pork producers right now, USDA does offer biosecurity resources for swine producers here .

Is the Swine Industry Ready for H5N1? Texas Veterinarian Says “No”

Fri, 21 Mar 2025 20:26:37 GMT

Nearly one year ago, USDA made a shocking announcement. Highly pathogenic avian influenza type A H5N1 (H5N1) was identified in milk and in cows on two dairy farms in Texas and two dairy farms in Kansas. A disease no veterinarian had previously feared in cattle had jumped from wild birds to domestic cows.

Scanlon Daniels, a large animal veterinarian with Circle H Headquarters in Dalhart, Texas, received a call 10 days prior to that announcement that he will never forget from one of his dairy clients that something wasn’t right with some of the cows.

“My client sent me a text: ‘I think I might have it,’” Daniels says.

He went out to the dairy, collected samples from four cows and submitted them to Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) as any good swine vet would do, he explained, during the American Association of Swine Veterinarians annual meeting. He also took some nasal swabs and tested those in his own lab. He did a follow-up, collecting samples from 20 different cows later on that week and sent those to the Iowa State University Veterinary Diagnostic Lab.

The four cows that initially presented symptoms of decreased rumination, decreased activity and nasal discharge were eventually confirmed to have H5N1. Right around that same time, he said there were reports from Texas Animal Health Commission about a backyard poultry flock in the county next door diagnosed with H5N1.

“We had a suspicion that it could have been influenza, because of what was going on with some of the detections in birds in that area,” Daniels says. “But from my standpoint, I was thinking about flu from all my experiences dealing with it in pigs, and it didn’t present as a primary respiratory pathogen. It presented as a mastitis pathogen. Once we knew to look for it in milk, it was super easy to find, but we had to get over that hurdle to be able to rapidly identify it.”

In the past 15 years, Daniels grew his practice to develop its own laboratory capabilities, conducting PCR and Elisa testing for swine, dairy and beef clients. This, combined with his involvement with H5N1 from before it was even identified as an issue in cattle, caused him to bring up an incredibly important question for the swine industry: Are you ready for H5N1?

Who is Steering the Ship?
To date, H5N1 has been discovered in one pig that was on a hobby farm with H5N1-infected poultry. Although this is considered an isolated incident and hasn’t been discovered in the commercial swine population, it needs to be on everyone’s radar, Daniels says.

Andrew Bowman, DVM, one of the country’s top swine influenza experts, joined The PORK Podcast during a special report on H5N1 last fall. A professor in the Department of Veterinary Preventive Medicine at The Ohio State University, he is well-known for his expertise in swine production medicine, veterinary public health and epidemiology.

“Across the swine industry, we routinely deal with influenza, so we’re pretty well versed in flu,” Bowman says. “But this adds a whole other character to the scene that we really don’t want reassorting with the flu viruses we already have.”

One of the things that makes H5N1 different than other new swine disease outbreaks is that the USDA has jurisdiction over H5 in any animal, so they have the regulatory authority, Daniels says.

“USDA had no rules or regulations around H5 in cattle, and we’re at the same place today in the swine industry,” Daniels adds. “If we were to find H5 in swine, USDA would have the authority and there are no rules or regulations around it.”

This has made the discovery of H5N1 in dairy cattle challenging in the past year, because it’s taken a long time for those regulations to be developed.

“There’s the state and federal aspect of that, where states have autonomy to set their own rules, and then federal rules can come in place that everybody has to abide by,” he points out. “There’s been this slowly evolving plan with a patchwork of regulations by different states. That’s been challenging to keep up with as a veterinarian and a producer.”

The recent COVID-19 pandemic has likely amplified concerns around influenza’s ability to be transmitted from humans to animals and from animals to humans.

“This has resulted in a high concern about influenza being the next COVID. Yes, that could happen. Today it hasn’t to that degree.”

Scanlon Daniels

People are fearful of government influence and interaction, he says.

“No one wanted to be first or second or third to get H5N1 in their dairy cattle – just like no one wanted to be first to get COVID-19. There was a reluctance to test because of the uncertainty of it,” Daniels explains. “People fear government overreach or regulations that wouldn’t be applied in a fair or equal way across the industry.”

The Stakes are High
Everybody has a stake in this issue, Daniels says. The challenge is that everybody comes to it with differing priorities regarding the issues at hand.

The American Association of Bovine Practitioners invited seven different groups that have the ability to provide vaccine to share about their technologies on a webinar. This gave avian and bovine veterinarians alike exposure to their vaccine technology.

“The hard part is getting everybody to agree on what needs to happen,” Daniels says.

But he believes the vaccine question is worth talking about.

“If it was just another influenza, we would have had a vaccine available in a couple weeks, honestly,” he says. “The government has the ability to authorize vaccine use under an emergency use exemption. For all the concerns that have been talked about with export markets, and how people might respond from a trade standpoint, they haven’t been willing to look at that. But if we could use vaccine on an experimental use basis, we would know a lot more by now about the value of that intervention.”

In a USDA update on March 20, Secretary of Agriculture Brooke Rollins said USDA is exploring the viability of vaccinating poultry for highly pathogenic avian influenza. However, Rollins said the use of any vaccine for poultry or any animal species has not been authorized at this time.

“I know there has been some misreporting on that,” Rollins said. “The day we rolled out the plan, I actually talked about the fact that we’re not ready to vaccinate. We need to do some more research, and so that has not changed, but I do look forward to this next process of learning more about getting more research done and perhaps seeing what makes sense for the country moving forward, once that is concluded.”

Another concern on Daniels’ mind is the implication with human health. Influenza A viruses are common in people. They are constantly changing and reassorting.

“Influenza viruses exist and circulate in people all the time,” says National Pork Board chief veterinarian Dusty Oedekoven . “The threat of influenza virus infection is ever present. It’s why healthcare providers recommend people get annual influenza vaccines to prevent against new strains of the virus that are emerging all the time.”

Daniels says the unknown transmission opportunities between humans and animals, especially pigs, can be concerning.

“The transmission from people to pigs is a legitimate concern. As an industry, it might be worthwhile doing some serological surveillance.”

Scanlon Daniels

At a recent bovine practitioners meeting, they surveyed 150 veterinarians and found three of them have had prior exposure to H5N1, he says. Some of those had no contact with dairy or birds.

“It would probably be wise for us to do some serosurveillance to know if people working at hog farms have had some exposure and it hasn’t transmitted yet,” he points out.

For example, his lab had a lot of infected milk come through before they knew what it was.

“My staff had legitimate fears and concerns we had to address,” Daniels says. “Fortunately, we didn’t experience any illness or lost time outside of the normal. That could have been different. We can’t lose sight of the human aspect of it. I am a human, a swine vet and a beef producer, so I can understand several aspects of it from a balanced way.”

Hurdle By Hurdle
At the end of the day, the swine industry has a lot to learn from what the dairy industry experienced in the past year, he says.

“On one hand, we have advantages relative to bovine veterinarians because we have a strong background and applied experience in diagnostics and strong working relationships with state and federal animal health officials,” Daniels says. “We have a mindset of disease elimination when possible and strong integrated relationships with producers. The swine industry also has the ability to direct Pork Checkoff dollars toward research (the dairy industry does not).”

On the other hand, he says many of the factors that have caused consternation will continue to be problematic if HPAI is identified in swine. Studies need to be done looking at H5N1 in swine, he says. If a sow is infected, does it transmit to pigs? Can her pigs shed it to contact controls? How could the movement of wean pigs spread the disease?

He also wonders if pigs have some cross-protective immunity at this point because influenza is pretty much endemic in almost all swine populations. And, even though it presents in the mammary system in cows, he argues the swine industry could do some additional work in growing pigs, because it would be easier to deal with there than on a sow farm.

One of the biggest hurdles is that H5N1 is a select agent. Once samples are known to be positive for H5N1 antigen, there are many requirements related to storage, handling and testing that come into play. Space is limited to research H5N1 and Daniels is concerned at the delay in testing this virus in swine.

“Another challenge is H5N1 is of economic significance to dairy producers but has not been great enough to stimulate much independent industry action.”

Scanlon Daniels

For comparison, the relative economic impact of H5N1 in dairy is estimated to be approximately 10% that of a porcine epidemic diarrhea virus (PEDV) outbreak in swine, he says.

“We have seen growing interest by veterinarians and producers in eliminating H1 and H3 influenza infections in swine, but the interest and adoption is less than what we see for porcine reproductive and respiratory syndrome and PEDV,” Daniels says. “Would we see the same if H5N1 was identified in swine?”

He believes the swine industry still has an opportunity to develop the response to H5N1 in commercial swine before it occurs.

“It’s time to get some of these questions answered that are important to us,” Daniels says. “If it were to happen, we need to be prepared to address some of the risk factors, things that are real versus the fear of the unknown.”

Editor’s Note: On March 12, APHIS confirmed the presence of highly pathogenic avian influenza H7N9 in a broiler chicken breeder flock in Mississippi. APHIS has previously documented H7 low pathogenicity avian influenza in U.S. wild bird surveillance this year and in previous years, but this is the first HPAI H7 case in commercial poultry in the U.S. since 2017. This H7N9 virus is a fully North American virus of wild bird-origin and is unrelated to the Eurasian H5N1 currently circulating in the U.S. Spillovers of avian influenza from wild bird sources can occur due to breaches in biosecurity. APHIS closely monitors these subtypes because H5 and H7 LPAI viruses in poultry species such as chickens and turkeys can mutate into highly pathogenic avian influenza.

More Funding Going to Tackle HPAI H5N1, Egg Imports are Now Underway to Stabilize Supply

Thu, 20 Mar 2025 17:41:08 GMT

On Thursday morning, USDA Secretary Brooke Rollins gave an update on progress the Trump administration is making on the five-prong strategy it unveiled Feb. 26 to combat avian influenza virus type A (H5N1).

Speaking to industry stakeholders, media and offices of elected officials, Rollins focused on the administration’s work to lower egg prices and improve supply, while also emphasizing the importance of biosecurity in protecting U.S. poultry flocks from the virus.

Regarding egg prices, she said wholesale prices are down nearly 50% from their peak in late February from $8.53 then to $4.08 currently.

However, Rollins said she realizes that wholesale prices don’t automatically show up as reductions in retail prices.

“I know for some of us who are shopping that we’ve seen egg prices drop immediately, which has been true for me. But then we’ll hear from people in other parts of the country where they have yet to see that reduction on their grocery store shelf.”

With Easter just a few weeks away, she acknowledged that egg demand is always “unusually high during the season,” and that egg prices could potentially move back up.

To help address the egg shortage, Rollins noted that shell egg exports have declined by 8%, “keeping more eggs in the U.S. and lowering prices.”

In addition, the Trump administration is allowing egg imports as a temporary measure to stabilize prices and supply. Rollins’ chief of staff Kailee Buller said this measure would likely be discontinued once those measures were achieved.

USDA Focuses On Biosecurity For Poultry Operations
Rollins said biosecurity in poultry flocks will continue to be a major part of the Trump administration’s plan to address H5N1, moving forward.

“Our pilot programs have proven that biosecurity is the most important thing our farmers can do to protect our flocks against the disease, at least right now,” she said.

The USDA is working closely, she said, with its federal partners including the U.S. Department of Health and Human Services (HHS), Centers for Disease Control (CDC), National Institutes of Health (NIH), and the Food and Drug Administration (FDA) to “combat avian flu as a unified federal family.”

On Wednesday, USDA announced it is expanding the availability of its biosecurity assessments to commercial poultry producers.

“These assessments, which were previously available on a limited basis have been extremely successful in improving biosecurity on individual premises and preventing the introduction or spread of avian influenza,” Rollins said.

While USDA is exploring the viability of vaccinating poultry for H5N1, she said the use of any vaccine for poultry or any animal species has not been authorized at this time.

“I know there has been some misreporting on that,” Rollins said. “The day we rolled out the plan, I actually talked about the fact that we’re not ready to vaccinate. We need to do some more research, and so that has not changed, but I do look forward to this next process of learning more about getting more research done and perhaps seeing what makes sense for the country moving forward, once that is concluded.”

Dairy Is Not Part Of USDA’s Primary H5N1 Focus
No information was offered during the conference call to address the issue of H5N1 in dairy cattle or other livestock or animal species.

Mike Watson, administrator of USDA-APHIS, said right now USDA is focused on the poultry vaccine.

“We’re looking for a vaccine that has sterilizing immunity but also an opportunity for us to have different introduction methods for the vaccine right now, as injections are the only possibility,” he said. “We need new tools, whether it’s water based, aerosol based, those kind of things. We’re looking for manufacturers to really look at what those options might be, to really provide us with a vaccine that matches the current strain but also is highly effective. And again, this is really focused on poultry.”

Buller said there is already quite a bit of research at USDA on the topic in dairy.

“Please rest assured, we are thinking of you all (in dairy). We know you all are impacted. But for this particular strategy, we have been hyper-focused on the poultry side. USDA has separate work streams as we’re working through this on the cattle and dairy side.”

One of the media asked whether Sec. Rollins had talked further with HHS Sec. Robert F. Kennedy Jr. regarding his idea of letting H5N1 burn through poultry flocks to identify birds that might have immunity or show resistance to the virus.

Buller answered the question, as Rollins had stepped away from the call. “I have not been engaged specifically with those conversations with the Secretary and Secretary Kennedy,” she said. “They are talking very regularly and you are aligned on the approach, but in terms of that specific topic, there’s no further light I can shed on that at this time.”

Assessments Available To Poultry Operations
USDA is offering two different, free, voluntary biosecurity assessments for poultry operations not currently affected by HPAI.

The first is a wildlife biosecurity assessment. The second is a general biosecurity assessment. Poultry producers can request one or both of these free assessments.

Per the wildlife biosecurity assessment, Rollins said USDA will conduct on-farm assessments at poultry facilities and provide recommendations to producers for facility repairs and wildlife management techniques. The assessments include a series of regular engagements, including wildlife hazard identification surveys, wildlife abundance surveys and wildlife management on the premises.

“USDA has assessed approximately 130 facilities to date (in 2025), and plans on doing significantly more moving forward and expanding that program,” she said.

For the general biosecurity assessment, USDA will work with poultry producers to review biosecurity plans and physical measures.

“This is a proactive resource for premises that are outside of avian flu control areas to identify and mitigate potential biosecurity gaps,” she said.

Funding Is Ramped Up To Address HPAI In Poultry
The USDA announced on Thursday that up to $100 million in funding will be available to support projects on avian influenza, prevention, therapeutics, vaccines and research.

“USDA will invest up to $100 million in these projects, which will identify and foster innovative solutions to fight avian flu and directly support American producers,” Rollins said during the conference call.

Funding is available through a competitive process to for-profit organizations, including manufacturers of vaccines, biologics and therapeutics, as well as states, universities, livestock producer organizations and other eligible entities, she noted.

USDA will prioritize one or more of the following. First, it will support the development of novel therapeutics to address HPAI in poultry. Second, it will support research to further understand the risk pathways of avian influenza for producers and to inform improved biosecurity and response strategies.

“Let me just say, as a quick aside, I’ve had multiples and multiples and multiples of conversations with some of our chicken farmers across the country —many of them have been highly successful at not having the bird flu infect their populations,” Rollins said. “Better understanding of risk pathways and realizing what best practices are is a big part of (this work).”

The third focus is on the development of novel vaccines to protect poultry from H5N1 while promoting biosecurity.

“That will all be part of the research funding opportunity that we announced about an hour and a half ago,” Rollins said.

USDA will test the efficacy of therapeutic interventions to prevent the virus and treat infected flocks.

“USDA, in consultation with HHS, has already had multiple conversations with Secretary Kennedy and leaders in the NIH and CDC, but will also be exploring prevention strategies to promote biosecurity in agriculture and in humans, to ensure limited impact on American farmers,” Rollins noted.

USDA is offering a webinar to assist interested applicants in learning more about the funding opportunity and how to submit a proposal on Tuesday, April 1 at 12 p.m. Eastern. No details on how to participate in the webinar have been communicated yet.

“As we try to do everything under this president and here at USDA, we will be as fast and efficient and effective as we can possibly be, working around the clock,” Rollins said.

Buller added that Sec. Rollins and her staff will continue to host update calls regularly.

“It’s very important to Sec. Rollins that we are showing progress on this five-prong plan and being honest and open with the public about what we’re up to and the progress and potential challenges that we have ahead,” Buller said. “We have an open door here, and we remain open to having conversations and hearing from stakeholders.”

EXCLUSIVE: Ag Secretary Brooke Rollins Provides Timing Update on $10 Billion in Emergency Relief Payments

Thu, 27 Feb 2025 16:36:22 GMT

Time is running out for USDA to issue the nearly $10 billion of economic relief payments to farmers . Congress approved a 90-day window to release those payments, and in an exclusive interview with U.S. Secretary of Agriculture Brooke Rollins Thursday morning, we asked when exactly those payments will be released. Rollins confirmed to Farm Journal that those payments will be released before the current deadline.

“Congress gave us until March 21, that is the ideal deadline,” Rollins said. “It looks like we’re going to be able to beat that, so it should be just around the corner.”

As USDA works to release those payments within the next few weeks, according to some sources, producers are banking on the payments, even making business decisions based on projected payment calculations.

Pro Farmer Washington policy analyst Jim Wiesemeyer says the only issue that could impact that timing is a possible government shutdown. If the government shuts down beginning March 15, and those payments haven’t been released yet, that could impact the March 21 deadline.

Wiesemeyer also reports based on history, the initial payment will likely be around 85% of the projected total, with a supplemental payment likely coming in the summer. Most expect the per acre payment rates to be in line with what staffers on the House Ag Committee released last year, which are:

Corn: $43.80
Soybeans: $30.61
Wheat: $31.80
Cotton: $84.70
Rice: $71.37

Payment Cap
Like other recent disaster programs, the payment limit for farmers will depend on how much of a farmer’s income is derived from agriculture. However, this program is based on average gross income rather than adjusted gross income (AGI).

The payment cap will be:

If < 75% of average gross income from 2020 to 2022 is from agriculture, then the limit is $125,000
If 75% or more of average gross income from 2020 to 2022 is from agriculture, then the limit is $250,000
USDA says standard FSA “actively engaged in farming” requirements apply

While USDA will determine the finalized per acre payments, these are the estimated American Relief Act payments for farmers.

Update on Timing of $1 Billion to Combat Avian Flu
Led by Rollins, USDA announced on Wednesday plans to invest up to $1 billion in new funding to combat impacts of highly pathogenic avian influenza (HPAI) and soaring egg prices.

“The important piece is not just this immediate short-term goal of getting the cost of eggs down and repopulating our layers and locking our barns down,” Rollins told Farm Journal on Thursday. “But much more importantly, perhaps, is figuring this out for the long term, so we’re not having the same conversation over and over and over again.”

The avian flu plan, which USDA rolled out on Wednesday, includes five major points:

Dedicate up to $500 million to help U.S. poultry producers implement “gold-standard” biosecurity measures. USDA has developed a successful pilot program, called Wildlife Biosecurity Assessments, to identify and implement more safety measures. USDA will pay up to 75% of the cost to address any identified biosecurity vulnerabilities at poultry farms.
Make up to $400 million of increased financial relief available to farmers whose flocks are affected by avian flu, and USDA will assist farmers in receiving faster approval to begin safe operations again after an outbreak.
USDA is exploring the use of vaccines and therapeutics for laying chickens. While vaccines aren’t a stand-alone solution, they will provide up to $100 million in research and development of vaccines and therapeutics, to improve their efficacy and efficiency. This should help reduce the need to depopulate flocks, which means killing chickens on a farm where there’s an outbreak. Note: USDA hasn’t yet authorized the use of a vaccine. Before making a determination, USDA will consult state leaders, poultry and dairy farmers, and public-health professionals. The agency will also work with trading partners to minimize potential negative trade effects for U.S. producers and to assess public-health concerns.
USDA will take other actions to lower the price of eggs. For starters, it will remove unnecessary regulatory burdens on egg producers where possible. This will include examining the best way to protect farmers from overly prescriptive state laws, such as California’s Proposition 12, which established minimum space requirements for egg-laying hens.
USDA will consider temporary import options to reduce egg costs in the short term. They will proceed with imports only if the eggs meet stringent U.S. safety standards and if they determine that doing so won’t jeopardize American farmers’ access to markets in the future.

As for the $500 million that will go toward beefing up biosecurity efforts, Rollins says that will happen immediately.

“The team is putting together right now the guardrails for that, but I think they’re almost finished, and that money should be moving out very quickly,” Rollins told Farm Journal. “That biosecurity money is based on a pilot program where 150 different egg laying farms were piloted on specific biosecurity measures. Of those 150, only one has seen the avian flu. Once they implemented, there’s a massive audit that USDA comes in. They help audit. We’re hiring a whole bunch of new folks to come on board to do that — and new epidemiologists to help us work through all of the science on this, and hopefully you see that immediately.”

Where is the $1 Billion Coming From?
At a time when the Trump administration is looking to save money, not spend, we asked Rollins where exactly is the $1 billion of funds going to be sourced.

“We’ve repurposed funds from other programs within USDA, so this is not spending new money,” Rollins said. “Clearly, we’re in an era where President Trump’s vision is to really streamline government, but this is not that. This is outside that lane. This is a really, really important issue. You know, it’s affecting every single American, not just our poultry producers. And so there’s short-term and long-term fixes here now.”

Some of that money, however, is coming from savings from the Department of Government Efficiency (DOGE).

“We are pulling it from multiple different pots. But yes, there’s no doubt that we’ve been able to find some serious savings in DOGE,” Rollins said. “We’ve canceled almost a thousand DEI trainings that were across USDA.... All of it adds up, and we’ve really pulled a lot of that money back. And now putting it where we think it really helps farmers and ranchers.”

What Will It Take for the Ag Economy to Recover

Rollins is set to give the keynote address at USDA’s Ag Outlook Forum on Friday. Rollins told Farm Journal there are a lot of farmers hurting in this economy, saying “it’s one of the worst for that industry that we’ve seen in decades.”

Considering 64% of ag economists think the row crop sector of agriculture is in a recession , we asked Rollins what it will take for the ag economy to recover.

“There’s no doubt, to your point, a lot of our producers in the different lanes are really hurting. Listen, we’ve got to get the cost of input down. We have got to get our export markets opened up around the world. I mean, we’re facing this year a $45 billion trade deficit,” said Rollins.

Rollins says when President Trump left the White House in 2020, there wasn’t a trade deficit. And she says the growign trade deficit is something President Trump wants to address.

“Just think about the amount of ag production that we were once moving out across the world that was keeping our farmers whole and making sure that they could make some kind of a profit,” said Rollins. “That’s not there anymore. Obviously, inflation, the cost of energy has absolutely decimated our producers. The input cost is up 30%. So when you’ve got all of these different factors that are basically piling on at one time, it’s it’s no surprise that sorghum, cotton and so many others are really hurting right now. And we’ve got to do something about that.”

As input prices remain elevated, and commodity prices are below break-even for some, Rollins says she and President Trump are aligned in what needs to happen to bring relief to farmers.

“My perspective, and the president’s perspective, is how do we achieve this through broader access to markets, broader access to capital, making sure that that the cost of inputs goes down. Hopefully with our energy plan, we see that happening almost immediately. And I think that will move into a different era for prosperity for ag, but there’s no doubt it is a dire, dire forecast right now without significant change.”

During the the first Cabinet meeting in President Trump’s second-term, which was held Wednesday, President Trump floated 25% tariffs on the European Union.

“Obviously, tariffs always come up. I’m always saying, ‘let’s be very, very careful and intentional how we move here,’” Rollins said about the first Cabinet meeting. “The border came up, immigration deportations came up. So all the things that the ag community is concerned about that came up, course, I’m at the table. My job is to ensure that that our community’s voice is heard, but also to help effectuate the president’s vision. And we’re moving forward on all fronts.”

Trump Administration Announces $1 Billion to Combat Avian Flu and Soaring Egg Prices

Wed, 26 Feb 2025 15:28:33 GMT

The Trump administration is investing up to $1 billion in new funding to combat impacts of highly pathogenic avian influenza (HPAI) and soaring egg prices.

USDA Secretary Brooke Rollins in the Wall Street Journal said, “There’s no silver bullet to eradicating avian flu.” She laid out a five-point plan to address the situation.

Dedicate up to $500 million to helping U.S. poultry producers implement “gold-standard” biosecurity measures. USDA has developed a successful pilot program, called Wildlife Biosecurity Assessments, to identify and implement more safety measures. USDA will pay up to 75% of the cost to address any identified biosecurity vulnerabilities at poultry farms.
Make up to $400 million of increased financial relief available to farmers whose flocks are affected by avian flu, and we will assist them in receiving faster approval to begin safe operations again after an outbreak.
USDA is exploring the use of vaccines and therapeutics for laying chickens. While vaccines aren’t a stand-alone solution, we will provide up to $100 million in research and development of vaccines and therapeutics, to improve their efficacy and efficiency. This should help reduce the need to “depopulate” flocks, which means killing chickens on a farm where there’s an outbreak. Note: USDA hasn’t yet authorized the use of a vaccine. Before making a determination, USDA will consult state leaders, poultry and dairy farmers, and public-health professionals. The agency will also work with trading partners to minimize potential negative trade effects for U.S. producers and to assess public-health concerns.
USDA will take other actions to lower the price of eggs. For starters, it will remove unnecessary regulatory burdens on egg producers where possible. This will include examining the best way to protect farmers from overly prescriptive state laws, such as California’s Proposition 12, which established minimum space requirements for egg-laying hens.
USDA will consider temporary import options to reduce egg costs in the short term. We will proceed with imports only if the eggs meet stringent U.S. safety standards and if we determine that doing so won’t jeopardize American farmers’ access to markets in the future.

Senate Ag Committee Chair John Boozman (R-Ark.) said, “Producers and consumers alike have experienced the economic burden of this outbreak since 2022. I applaud Secretary Rollins and the Trump administration for prioritizing a strategy to combat this evolving threat. I look forward to working with USDA to ensure all poultry and livestock producers’ unique challenges are taken into consideration and they have the tools they need to address animal disease risks.”

In the Wall Street Journal Op-Ed , Rollins said some of the money will come from cuts to USDA spending by the Department of Government Efficiency (DOGE).

“Egg prices are skyrocketing, and it isn’t simply a matter of inflation. Grocery prices rose by more than 20% on President Biden’s watch, but the average price of a dozen eggs went up 237%, from $1.47 in January 2021 to $4.95 last month,” Rollins said wrote in the Wall Street Journal. “This matters for American families because eggs are a healthy, accessible and generally affordable source of protein.”

By the Numbers: Soaring Egg Prices
USDA upped its 2025 egg price forecast to a 41.1% increase (range of up 15.0% to 74.9%), more than double the 20.3% rise they forecast in January. USDA started their 2025 egg price forecast in July 2024 looking for them to decline 7.6% versus 2024

“Retail egg prices increased by 13.8% in January 2025 after rising by 8.4% in December 2024,” USDA detailed. “Retail egg prices continue to experience volatile month-to-month changes due to an outbreak of HPAI that began in 2022. HPAI contributes to elevated egg prices by reducing egg-layer flocks and egg production. About 18.8 million commercial egg layers were affected by HPAI in January 2025, the highest monthly total since the outbreak began in 2022.”

Egg prices in January were 53% higher than January 2024 and “surpassed the previous peak prices in January 2023,” USDA detailed.

I just left a message for Chris Kempczinski, CEO of McDonalds USA, thanking him for the choice to not add surcharge to eggs. THANK YOU @McDonalds!!!

Avian Flu a Top Priority for Rollins
On Monday, Rollins met with poultry farmers and industry leaders in Texas to address the ongoing avian flu crisis. She toured a Cal-Maine Foods facility in Bogata before hosting a roundtable in Mount Pleasant, where discussions focused on outbreak response and mitigation strategies. Rollins criticized the Biden administration’s handling of the issue, emphasizing the Trump administration’s commitment to supporting farmers and stabilizing egg prices.

“Clearly, this is a massive issue for our poultry producers, especially our egg layers,” Rollins told AgriTalk’s Chip Flory, in an exclusive interview, during Top Producer Summit. “Ensuring that we have a plan, not just for the short-term to bring down egg prices, which the president is very focused on, but for the long-term. What are the best practices around the world? Why in America have we been hit so hard? Why did the last USDA, a couple of years ago, recognize it as a major issue, but not many steps were taken.”

Just hours after being confirmed, Rollins’ first official meeting at the White House was on avian flu. She told Flory it’s her top priority right now, and she’s gathered a team from within USDA and the White House to focus on the issue.

“I’ve been talking to governors. I’ve been talking to the companies that are facing this. I’ve been talking to grocery. I mean, we’ve been talking to everyone, trying to come up with a big toolkit to be able to really approach this and hopefully figure out a way to, again, solve it for the long-term,” Rollins said.

Flory followed up by asking Rollins if vaccines will be one of the tools used by USDA.

“Vaccines are being discussed right now. I think that there is a lot of opinion on that on both sides. And we’re working through all of that right now,” Rollins told Flory.

The big announcement released on Wednesday did not include any plans to approve vaccines to combat the disease.

As the Trump Administration Shifts Strategy on Avian Flu, it’s a Complicated Issue in Need of a Long-Term Solution

As Trump Administration Shifts Strategy on Avian Flu, It's a Complicated Issue in Need of Long-Term Solutions

Tue, 25 Feb 2025 14:36:46 GMT

The Trump administration is rolling out a new strategy to combat avian flu, moving away from mass culling of infected flocks of egg-laying chickens. But as Agriculture Secretary Brooke Rollins told Farm Journal in an exclusive interview, the key to solving the issue is to find a solution that doesn’t just address the avian flu outbreak in the short-term. The plan also needs to find a solution that works long-term, as well.

USDA’s food price outlook report released Tuesday shows the sticker shock shoppers are seeing for egg prices. The report egg prices for 2025 now more double their previous forecast, now up 41.1% midpoint versus 20.3% last month.

Also on Monday, Rollins met with poultry farmers and industry leaders in Texas to address the ongoing avian flu crisis. She toured a Cal-Maine Foods facility in Bogata before hosting a roundtable in Mount Pleasant, where discussions focused on outbreak response and mitigation strategies. Rollins criticized the Biden administration’s handling of the issue, emphasizing the Trump administration’s commitment to supporting farmers and stabilizing egg prices. Following the roundtable, she spoke with local media about USDA’s efforts and the impact on Texas agriculture

That followed the Trump administration introducing a new plan last week, which was spearheaded by National Economic Council Director Kevin Hassett and Rollins. The plan prioritizes enhanced biosecurity measures and medication to control the spread of the virus in egg-laying flocks.

“Clearly, this is a massive issue for our poultry producers, especially our egg layers,” Rollins told AgriTalk’s Chip Flory, in an exclusive interview. “Ensuring that we have a plan, not just for the short-term to bring down egg prices, which the president is very focused on, but for the long-term. What are the best practices around the world? Why in America have we been hit so hard? Why did the last USDA, a couple of years ago, recognize it as a major issue but not many steps were taken?”

Thank you East Texas! I am so grateful to so many as the learning tour continues — yesterday a poultry facility and a roundtable with #local farmers and ranchers to solicit feedback on combatting bird flu and lowering the cost of eggs. @POTUS and our team at @USDA remain… pic.twitter.com/ATXTEz0tVk

Flory followed up by asking Rollins if vaccines will be one of the tools used by USDA.

“Vaccines are being discussed right now. I think that there is a lot of opinion on that on both sides. And we’re working through all of that right now,” Rollins told Flory.

Part of the Trump administration’s new strategy on avian flu released so far includes:

Biosecurity and Medication: Improved containment protocols and medication aim to reduce reliance on widespread culling.
Smart Perimeter Approach: Targeted containment methods will enhance efficiency in preventing outbreaks.
Collaboration: Government scientists and global academic experts are contributing to the plan’s development.

How to Get More Eggs in the Short-Term
The National Chicken Council (NCC) is also petitioning the FDA to lift a regulation that prevents broiler industry eggs from entering the food supply, arguing the move could ease record-high egg prices caused by the bird flu outbreak.

The 2009 rule forces broiler producers to discard surplus hatching eggs instead of selling them to processors, despite government risk assessments affirming their safety. If granted, the request would allow nearly 400 million eggs annually to be used in processed foods like bread, pasta and mayonnaise, alleviating strain on table egg supplies.

NCC previously sought relief under the Biden administration in 2023 but was denied. Now, with egg prices soaring, the organization is urging swift action from the Trump administration.

USDA Reports Decline in Egg production, Signs of Recovery Ahead

USDA’s latest report highlights key trends in the poultry industry, including a 4% decline in U.S. egg production for January 2025. This drop is largely due to a 4% reduction in laying hens, driven by the ongoing avian influenza outbreak.

However, signs of recovery are emerging: egg-type chick hatching rose by 6%, and incubation numbers increased by 7%. Meanwhile, broiler production is growing, with a 3% rise in broiler chick hatching. USDA will release updated forecasts on March 11, offering a clearer picture of the industry’s trajectory.

More details:

The number of layers fell to about 363 million in January, down 3.8% from a year ago.
Egg production of 8.865 billion was down 4.2% and the lowest for the month since 2016 — when there was a previous major outbreak of bird flu.

Egg Production

(Bloomberg)

Denny’s became the latest breakfast chain to announce an egg surcharge. Earlier this month, Waffle House introduced a temporary 50-cent surcharge per egg.

Major retailers, including Costco and Trader Joe’s, have had to act as well by imposing limits on how many eggs one customer can buy. According to USDA, the avian flu has killed more than 140 million egg-laying birds in the country since 2022. At least 18.9 million birds have been culled in the past 30 days alone.

Egg Prices and Market Conditions
Conventional table eggs jumped 36 cents a dozen nationally last week, on average.

Negotiated wholesale prices for graded loose eggs are firm to moving higher with a higher undertone. Demand for retail is moderate to good, while food service interest is lower. Offerings are very light, with little chance of improvement due to ongoing highly pathogenic avian influenza (HPAI) impacts on productive flocks.

Price Trends

National trading: White large shell eggs increased $0.33 to $8.07 per dozen
New York market: Large cartoned shell eggs rose $0.24 to $8.47 per dozen
Midwest region: Large white shell eggs increased $0.28 to $8.09 per dozen
California benchmark: Large shell eggs rose $0.05 to $9.22 per dozen

Supply and Demand
Shell egg demand has increased over the past week, with marketers struggling to cover needs due to reduced supplies from HPAI outbreaks. Spot market bids routinely outpace offers, often by a factor of ten, with prices setting daily records. Shell egg shortages are now impacting most major markets.

Inventory and Production

Overall shell egg inventory declined 2%
Large class shell eggs inventory is down just over 1%
Cage-free egg stocks decreased 3.5%
Breaking stock inventory gained 2%
Total estimated table egg production unchanged from last week and last year

Breaking and Processing
Breaking schedules are generally reduced, running 3% below year-ago levels. The volume of eggs processed last week decreased just under 1%. Production of whole eggs was up nearly 3%, while egg components (whites and yolks) continue to decline.

Frozen Egg Storage
December monthly volume of frozen eggs in storage declined 7% from November, 38% below the December 2023 level. This is the lowest level of egg products stocks recorded in the last 10 years.

NCC’s Petition to Bring More Eggs Into the Market

As noted above, the National Chicken Council is also petitioning the FDA to lift a regulation preventing broiler industry eggs from entering the food supply.

· Consumer safety vs. potential economic benefits: The FDA determined that allowing the use of surplus broiler eggs would not maintain the same level of public health protection as the current egg safety rule. The agency prioritizes consumer safety over potential economic benefits.

· Refrigeration requirements: The 2009 rule requires all eggs entering the food supply to be kept at 45°F within 36 hours of being laid. Broiler eggs are typically stored at 65°F, which is incompatible with this requirement.

· Different risk profiles: While the NCC argues that pasteurized surplus broiler eggs present a different risk profile than raw table eggs, the FDA has not been convinced by this argument.

· Regulatory jurisdiction: The FDA has authority over shell eggs under the Federal Food, Drug, and Cosmetic Act, while USDA’s Food Safety and Inspection Service (FSIS) regulates egg products. This division of responsibilities complicates the decision-making process.

· Previous rejections: The FDA has consistently denied similar petitions in the past, including one in June 2023. This suggests a long-standing policy position that is unlikely to change without significant new evidence or circumstances.

What Could Happen Moving Forward

USDA officials and analysts clearly understand the issue, but they are dealing with a topic that involves short- and long-term issues, FDA and White House officials. Also, throw in politics, with Democrats asking almost daily what the White House is doing about high egg prices.

A whole-of-government approach is evident on this issue via the Trump administration. That was not the approach on this topic during the Biden administration, even though various steps were taken by then USDA Secretary Tom Vilsack. They just came too late or were not aggressive enough, sources conclude.

Industry contacts say the failure of former President Biden’s team to deal with the spread of HPAI means both a short- and long-term approach is now needed. There is only so much that can be done in the short run to lower egg prices. That topic should have been dealt with via more effective HPAI policy a few years ago, contacts advise. It was not.

The push is on for a multi-focus, all-inclusive approach including:

An increased focus on biosecurity, but with funding to help the industry accomplish that because of indemnity and other issues.
Finding different modes of administering medications, such as via water, feed and aerosols. But those methods are not yet available. Thus the need for expanded research funding on this topic.
Coming up with a trade strategy that could involve regionalization (trading with states outside impacted areas). But that has to be negotiated with trading partners, and that takes time. Also, industry officials are very hesitant about trade issues. A regionalization approach could be taken, but only after more vaccines are available. However, there are already regionalization agreements in place with some countries on bird flu. One question is what would any vaccination effort do to those regionalization agreements?
Increasing imports of eggs, but this could be limited and presents some quality issues and food safety issues (testing, etc.). But egg exporting countries are increasingly looking at the U.S. market due to prices and wanting to boost exports.
Any discussion of an embargo on U.S. egg exports should be moot. Reason: embargoes do not work. Example: The Carter grain embargo in 1980 against the then Soviet Union.

Vaccines:
USDA recently granted Zoetis a conditional USDA approval for an avian flu vaccine. Major poultry and dairy organizations back vaccine use to control the virus.

However, several problems exist regarding vaccines, including the trade angle previously discussed, and the fact that their effectiveness timeline wears off. Also, HPAI is multifaceted with different mutations causing vaccine-related issues.

As for FDA, if the agency is convinced somehow to temper its current safety rule, concerns still exist regarding increased threats of salmonella.

If the NCC petition would be approved in some way, increased testing for salmonella is just one requirement. Any cost-benefit analysis is difficult at best to do on this topic. Of note: It will be curious to see what HHS Secretary JFK Jr. says about this and other HPAI issues, especially the use of vaccines.

Risks:
If a change in the major depopulation strategy is implemented, the concern is that if it does not work, an explosive increase in HPAI cases could follow.

Upshot:
Limited avenues are available in the short run regarding bringing down egg prices, and containing HPAI. As previously mentioned, the reason for that in part is this topic was not taken as seriously as it should have been during the Biden administration because no such all-of-government approach was taken.

A likely game plan will or should be to lay the groundwork to deal with HPAI in the long run so it does not surface again years from now. But this will take time to unfold. Regarding egg prices, any effort to stop U.S. egg exports will likely be rejected. That means increase supply via imports and eventually more U.S. egg production, and/or reduced demand via higher prices.

Trump Administration Shifts Strategy on Avian Flu

Mon, 17 Feb 2025 00:38:30 GMT

The Trump administration is rolling out a new strategy to combat avian flu, moving away from mass culling of infected flocks. Spearheaded by National Economic Council Director Kevin Hassett and USDA Secretary Brooke Rollins, the plan prioritizes enhanced biosecurity measures and medication to control the spread of the virus.

Key Points of the New Strategy

Biosecurity and Medication: Improved containment protocols and medication aim to reduce reliance on widespread culling.
Smart Perimeter Approach: Targeted containment methods will enhance efficiency in preventing outbreaks.
Collaboration: Government scientists and global academic experts are contributing to the plan’s development.

Recent Developments

Vaccine Approval: Zoetis received conditional USDA approval for an avian flu vaccine.
Industry Support: Major poultry and dairy organizations back vaccine use to control the virus.

Concerns and Challenges

Trade Impact: The National Chicken Council warns that vaccinating flocks could hinder poultry exports.
Efficacy of Previous Measures: Critics argue that the Biden administration’s mass culling approach was costly and ineffective.
Ongoing Outbreak: The flu has affected over 150 million birds since 2022, driving up egg prices and causing supply shortages.

Future Outlook

The plan’s success hinges on industry adoption and global trade acceptance. Balancing effective disease control with maintaining poultry exports remains a critical challenge for the administration.

NEC-Led Task Force on HPAI/Egg Prices to Confront Hurdles, Challenges

Hassett is working with industry experts and government analysts and officials, including those at USDA. Secretary Rollins late Thursday heard from various experts on the topic.

The emergence and spread of new avian influenza variants have significantly impacted egg prices, poultry production, and resulted in public health concerns, necessitating ongoing vigilance and adaptive strategies from both the industry and government agencies. Some of the issues:

Background

Bird flu was present during the first Trump administration (2017-2021). Several notable events related to avian influenza occurred during this period:

Outbreaks in 2017

In March 2017, an outbreak of highly pathogenic avian influenza (HPAI) H7N9 virus was detected in two commercial chicken breeder flocks in the United States.
This North American lineage HPAI H7N9 virus was genetically unrelated to the Asian lineage HPAI H7N9 viruses reported in China.

Policy Continuation

A USDA bird flu response plan, updated in May 2017 during Trump’s first administration, incorporated policy guidance based on lessons from influenza outbreaks during the Obama and first Trump administrations. The plan stated that “rapid depopulation of infected poultry is critical to halt virus transmission and must be prioritized.”

Depopulation Strategy

During a March 2017 bird flu outbreak, a USDA report indicated that “nearly 253,000 birds were depopulated.”
This depopulation strategy was a continuation of long-standing practices to prevent bird flu from spreading, as confirmed by agriculture experts.

While bird flu was present during Trump’s first term, the current widespread outbreak affecting cattle and causing human infections began in 2022, after Trump left office. The ongoing situation presents new challenges for the incoming Trump administration in 2025.

The Biden administration faced significant bird flu outbreaks during its tenure, with the H5N1 virus causing widespread impacts across the United States. Here’s an overview of the outbreaks and the actions taken:

Outbreaks

The current H5N1 outbreak began in 2022 and intensified throughout the Biden administration.
By early 2025, the virus had affected over 130 million birds, including both wild and domestic populations.
The outbreak expanded to dairy cattle, with 925 dairy herds across 16 states infected by October 2024.
Human cases were reported, with 67 confirmed cases and one fatality in the U.S. by early 2025.

Actions Taken

The Biden administration and then USDA Secretary Tom Vilsack implemented several measures to address the outbreak:

Funding and Resource Allocation

By January 2025, the administration had spent approximately $1.8 billion battling bird flu since the spring of 2023.
An additional $306 million was allocated in early 2025 for various response efforts.
In May 2024, nearly $200 million was provided to contain the outbreak, with $98 million for dairy farms and $101 million split between the FDA and CDC.

Testing and Surveillance

USDA implemented a Federal Order in May 2024 requiring testing of cattle before interstate movement.
In December 2024, a new mandate was announced to test the national milk supply for bird flu.
Enhanced testing and monitoring strategies were planned to better assess the presence of H5N1.

Biosecurity Measures

Vilsack emphasized the importance of improved biosecurity as a key strategy to limit the spread of H5N1.
USDA announced assistance for producers with H5N1-affected premises to improve on-site biosecurity.

Interagency Cooperation

USDA worked closely with the FDA on lab testing and with the CDC on public health matters.
A response team including four HHS agencies (CDC, FDA, NIH, and ASPR) was established to work with USDA. (ASPR is the Administration for Strategic Preparedness and Response.)

Public Health Initiatives

Funds were allocated to enhance hospital readiness and conduct research on therapeutics, diagnostics, and vaccines.
Local jurisdictions received funding to increase monitoring of high-risk populations, such as livestock workers.

Bottom Line: The above actions demonstrate the Biden administration’s multifaceted approach to addressing the H5N1 outbreak, focusing on containment, research, and protection of both animal and human health. However, despite these efforts, the outbreak expanded to dairy cattle, with 925 dairy herds across 16 states infected by October 2024. Human cases continued to occur, with 67 confirmed cases and one fatality by early 2025. Critics argued that the Biden administration’s response was not swift or comprehensive enough.

Vaccines

They are seen as impractical but could be used in targeted areas. Most available vaccines for avian influenza in chickens are administered through injection. This method, while effective, can be time-consuming and stressful for the birds, especially in large-scale poultry operations.

Currently, there are limited options for vaccinating chickens against bird flu via feed or water, but research is ongoing to develop more convenient methods of vaccine administration

New Variants

The disease is a moving target. USDA under then Secretary Tom Vilsack conditionally approved a vaccine made by Zoetis, containing a killed version of an H5N2 variant designed to work against circulating H5N1 variants. However, the effectiveness of vaccines may be compromised as new variants emerge, potentially requiring frequent updates.

Vilsack, during his tenure as USDA Secretary, took several steps regarding HPAI vaccines, but the situation has evolved over time:

Vaccine approval and funding. In 2016, Zoetis received a conditional license for its H5N1 vaccine and a contract award for the USDA’s National Veterinary Stockpile. This vaccine was approved under Vilsack’s leadership, as he served as USDA Secretary from 2009 to 2017, and then again from 2021 until Jan. 2025.
Vaccine fate. The Zoetis H5N1 vaccine approved in 2016 remained in the National Veterinary Stockpile until 2021 but was never used. This suggests that the vaccine was eventually discarded or removed from the stockpile without being deployed.
In August 2024, Vilsack authorized the first field trial of an H5N1 vaccine for cattle.

Of note: As of February 2025, Zoetis received a conditional license from USDA for its Avian Influenza Vaccine, H5N2 Subtype, Killed Virus, for use in chickens.

USDA has allocated significant funding for HPAI response:

In May 2024, Vilsack approved the transfer of $824 million from the Commodity Credit Corporation to the Animal and Plant Health Inspection Service (APHIS) for HPAI response efforts. This was in addition to a previous approval of $1.3 billion in emergency funds to tackle nationwide HPAI detections.
Former USDA Secretary Vilsack revealed that USDA was accelerating vaccine production for bovines, with seven potential vaccine candidates in development.

While not yet widely available, some alternative methods for vaccinating chickens against bird flu are being explored:

Spray vaccination: Some researchers have evaluated immune responses in chickens vaccinated via coarse spray with adenovirus-vectored avian influenza vaccines. This method shows promise for mass immunization of poultry, potentially eliciting both systemic and mucosal immune responses.
Drinking Water: As of now, there are no available vaccines that can be delivered through drinking water for avian influenza. However, this route of administration is being researched as a potential method for mass vaccination.
Aerosol/Spray: Only one vaccine is currently available for aerosol/spray administration. This method could potentially allow for easier mass vaccination of poultry flocks.

Challenges

The development of vaccines suitable for mass application methods outside hatcheries, such as via drinking water or spray/aerosolization, is still in progress. These methods would greatly simplify the vaccination process for large-scale poultry operations. Researchers are working on various approaches to make vaccination more practical:

Vectored vaccines: Some vaccines use viral vectors, like adenoviruses, to deliver avian influenza antigens. These may be more amenable to alternative administration routes.
Mucosal immunity: Spray and aerosol methods are being explored to target mucosal immune responses, which could provide better protection against respiratory infections like avian influenza.

Of note: While progress is being made, as of now, most approved and effective vaccines for avian influenza in chickens still require injection. The development of feed- or water-based vaccines remains an active area of research in the poultry industry.

Another Issue:

Changing variants of avian influenza significantly impact the egg price situation and overall poultry industry. Here’s how:

Emergence of New Genotypes. A new genotype of avian influenza, D1.1, emerged in wild migratory birds in September 2024 and subsequently spread to domestic poultry. This new variant has had severe consequences:

Increased spread across North America’s four migratory waterfowl flyways.
Spillover into poultry, humans, and even cows.
Caused a severe flu case in British Columbia and a death in Louisiana.
Scientists announced they found D1.1 in infected dairy cattle in Nevada for the first time. A dairy farm worker tested positive for H5N1, the state’s first reported human case.
Some scientists fear the D1.1 variant carries a new mutation that helps the virus copy itself more easily onto the cells of mammals, including humans.
Some scientists suspect a new strain is spreading via dust from bird droppings, carried by the wind.

Impact on Poultry and Egg Production.

The emergence of new variants has led to:

More than 20 million egg-laying chickens in the U.S. died in the last quarter due to the bird flu outbreak. This figure includes both chickens that died from the virus and those that were culled to prevent further spread of the infection. This recent toll represents the most severe impact on America’s egg supply since the outbreak began in 2022.
Reduction in the conventional egg-laying flock by 3.7% in January 2025 alone.
Significant drop in egg production, falling to 9.1 billion dozen in 2022 from 9.4 billion dozen in 2019.
The losses have affected all major production systems, including conventional caged, cage-free, and certified organic types (with some major differences as noted below).
Egg prices have soared to their highest levels in years, largely driven by the virus (details below).
The U.S. egg industry now has 8% fewer egg-laying hens than it did three years ago.
The federal government has allocated substantial funds to compensate farmers, with USDA spending $1.25 billion on payments to farmers since the outbreak started in 2022.
New bird flu outbreaks have also struck major egg-laying operations in Indiana and Georgia, leading to heists of the precious commodity and the sight of empty supermarket shelves where cartons of eggs should be.
New York Governor Kathy Hochul recently ordered all live-bird markets in New York City and some surrounding areas to shut down for a week to stem the spread of the virus. Three ducks at the Queens Zoo died of bird flu and as many as 12 birds at the Bronx Zoo that died after possible exposure are being tested for the virus.

The bird flu outbreak has significantly impacted the availability of organic and cage-free eggs, though in some unexpected ways:

Impact on Organic Egg Production

Less affected: Organic egg production has been less impacted by the bird flu outbreak compared to conventional egg production.
Smaller flocks: Organic egg-laying hens typically live in smaller flocks with more spacious conditions, which may contribute to their lower infection rates.
Price stability: Organic egg prices have been relatively more stable due to different pricing practices, with producers often setting long-term strategic prices with retailers.

Cage-Free Egg Availability

Disproportionate impact: Despite representing only about a third of U.S. egg layers, cage-free hens contributed to nearly 60% of all bird flu cases in 2024.
Supply challenges: The disproportionate impact on cage-free flocks has led to significant supply issues, especially in states with cage-free egg laws.
Recovery difficulties: Rebuilding cage-free flocks can be more challenging due to fewer sources and stricter regulations in some states.

Market Dynamics

Pricing anomalies: In some areas, like New York City, organic and cage-free eggs have been priced lower than conventional eggs due to existing contracts.
Potential price increases: As contracts expire, prices for organic and cage-free eggs may increase significantly.
State regulations: Nine states, including California and Colorado, have laws requiring eggs to be from cage-free hens, further complicating supply issues.

Other Issues:

Cage-free transition: About 40% of U.S. commercial egg layers are now in cage-free systems, up from just 30 million in 2015.
Supply/demand imbalance: The growth in cage-free egg demand has outpaced supply, exacerbated by bird flu outbreaks.
Bottom line: While organic eggs have been somewhat less affected by the bird flu outbreak, cage-free egg production has faced significant challenges. This has led to complex market dynamics, including unexpected pricing patterns and potential future shortages, particularly in states with cage-free egg laws.

Economic and Trade Implications.

Changing variants can affect international trade and economic stability:

The presence of highly pathogenic avian influenza (HPAI) restricts international trade in live birds and poultry meat.
New variants may lead to more stringent trade restrictions, further impacting national economies.

Human Health Concerns

As the virus evolves, there are increasing concerns about human health:

The D1.1 genotype has infected humans, with 68 confirmed cases and one fatality in the United States.
Experts worry that as the virus replicates, the chance of a mutation allowing human-to-human transmission increases.

Egg Prices

Egg prices in the United States have reached unprecedented levels, with the average cost of a dozen Grade A eggs hitting a record high of $4.95 in January 2025, but prices in individual states and stores can be much higher or lower. This represents a significant increase from previous years, with prices nearly doubling since 2024. The surge in egg prices has been particularly dramatic, with a 15% increase from December 2024 to January 2025 alone.

Several factors have contributed to the soaring egg prices:

Avian influenza outbreak: The primary driver of the price increase is an ongoing outbreak of highly pathogenic avian influenza (HPAI) that began in 2022. This outbreak has led to the culling of millions of chickens, significantly reducing the egg-laying population.
Supply chain disruptions: The bird flu epidemic has caused severe disruptions in the egg supply chain, with the population of conventionally caged chickens reduced by 8%.
Supply/demand imbalance: Consumer demand for eggs has remained steady despite the price increases, contributing to the supply-demand imbalance.
Shift in consumer preferences: There has been a growing preference for specialty eggs, such as cage-free and organic varieties, which are typically more expensive.
State Regulations: Some states, like California, have implemented stricter regulations requiring eggs to be sold from cage-free hens, further impacting prices.

Impact on consumers and businesses. The egg price surge has had widespread effects:

Grocery store limitations: Some grocery chains, including Trader Joe’s and Kroger, have placed limits on the number of eggs customers can purchase.
Restaurant surcharges: Restaurants like Waffle House have implemented per-egg surcharges to offset the increased costs.
Regional price variations: Prices vary significantly by region, with some areas seeing even higher costs. For example, in California, a carton of two dozen eggs can cost $13.49.

Egg Price Outlook

USDA predicts that egg prices could rise by up to 20% in 2025. The duration of high prices remains uncertain, as it depends on controlling the spread of avian flu and replenishing the egg-laying chicken population.

Experts suggest it may take at least another three to six months before prices begin to moderate. But some analysts say if a way can be found to deal with HPAI, egg prices would tumble. As consumers grapple with these high prices, some are adapting by reducing egg consumption or seeking alternatives. The situation continues to evolve, with both political and economic implications as the country faces this ongoing challenge in the food supply chain.

Does the U.S. import and export eggs? Yes.

Total egg exports from the U.S. in 2024 amounted to 172.8 million dozen eggs. This figure includes both table eggs and egg products (converted to shell egg equivalent). Breaking this down further:

Table egg exports: 84.3 million dozen
Egg product exports: 24,834 metric tons
The total value of egg exports in 2024 was $314.2 million, an increase of 5.9% compared to 2023.
In 2023, the U.S. exported $144.9 million worth of eggs, making it the 6th largest exporter globally. The U.S. maintains a positive trade balance in eggs, with exports exceeding imports by $139.6 million in 2023.

Imports

In 2023, the U.S. imported $110.15 million worth of eggs, primarily from Canada, the Netherlands, and the United Kingdom.

The U.S. generally is a net exporter of eggs, with exports significantly outweighing imports.

The top egg-exporting countries globally in 2023 were:

Netherlands: $610.1 million (20.5% of global egg exports)

The import of eggs into the U.S. is subject to strict regulations, including requirements for USDA import permits, veterinary health certificates, port inspections, and import quarantines. These measures ensure the safety and quality of imported eggs entering the U.S. market.

The U.S. gov’t has several potential options to address the rising egg prices:

Regulatory Actions

Investigate price gouging: The Federal Trade Commission (FTC) could investigate potential antitrust violations or price gouging in the egg industry. Some lawmakers have urged the FTC to probe egg producers for potentially coordinating efforts to restrict supply and sustain inflated prices.
Ease FDA regulations: The National Chicken Council (NCC) has petitioned the FDA to modify policies that force the broiler industry to destroy safe, nutritious eggs. Relaxing these regulations could increase egg supply and potentially lower prices. The issue stems from a 2009 FDA rule known as the Shell Egg Rule, which requires all shell eggs to be refrigerated at or below 45°F within 36 hours of being laid. This rule, intended for table eggs, inadvertently affects surplus broiler hatching eggs. Broiler eggs intended for hatching must be stored at 65°F for up to five days before determining which eggs are needed for hatching. This process is incompatible with the FDA’s refrigeration requirements, forcing the broiler industry to discard surplus eggs instead of sending them to egg breakers for processing into liquid egg products.

The NCC has requested FDA to: Exercise enforcement discretion to allow surplus broiler eggs to be processed into egg products under USDA Food Safety and Inspection Service (FSIS) jurisdiction; Exempt surplus broiler hatching eggs intended for breaking from the refrigeration requirements in the Shell Egg Rule. NCC argues that the current policy results in significant waste, costing the broiler industry over $27 million annually. Allowing these eggs to be used would help alleviate egg shortages and high prices, especially during events like the recent highly pathogenic avian influenza (HPAI) outbreak. The eggs would be safe for consumption as they would be pasteurized during processing, which is effective in controlling Salmonella.

As of February 2025, FDA has not yet granted the NCC’s request. The FDA denied a similar request on June 12, 2023, stating that the proposed action would not maintain the same level of public health protection as the current egg safety rule.

Policy Interventions

Address avian flu outbreak: The government could allocate more resources to combat the ongoing bird flu crisis, which has significantly impacted poultry populations and egg production since 2022.
Implement price controls: While controversial and unlikely under the Trump administration, the government could consider temporary price controls on eggs to limit further increases.
Increase imports: Easing restrictions on egg imports could help supplement domestic supply and potentially lower prices.

Economic Measures

Provide subsidies: The government could offer subsidies (incentives) to egg producers to offset increased production costs and encourage greater supply.
Offer consumer relief: Implementing targeted financial assistance or tax credits for low-income families could help offset the impact of high egg prices.

USDA has several potential measures to stabilize egg prices:

Enhance biosecurity: Promote and enforce stricter biosecurity measures across poultry farms to prevent the spread of highly pathogenic avian influenza (HPAI).
Increase surveillance: Improve monitoring and early detection of HPAI outbreaks to minimize their impact on egg production.
Investigate price gouging: Collaborate with the Federal Trade Commission and Department of Justice to scrutinize potential anti-competitive practices in the egg industry.
Enhance price discovery: Implement new regulations to improve fairness and transparency in pricing mechanisms for poultry farmers.
Promote competition: Support smaller egg producers and encourage market diversification to reduce reliance on large conglomerates.
Expedite flock replacement: Facilitate faster repopulation of laying hen flocks after HPAI outbreaks.
Address labor shortages: Develop programs to alleviate workforce issues in the egg industry that hamper production.
Ease import restrictions: Consider temporary measures to increase egg imports and supplement domestic supply.
Implement purchase limits: Encourage retailers to set temporary limits on egg purchases to prevent panic buying and ensure fair distribution.
Monitor retail practices: Scrutinize grocery stores’ pricing strategies and promotional activities to prevent unjustified price hikes.
Invest in research: Fund studies on HPAI-resistant poultry breeds and alternative production methods to increase resilience in the egg industry.
Improve forecasting: Enhance data collection and analysis to better predict and prepare for future supply chain disruptions.

Challenges and Limitations

Government intervention in markets can have unintended consequences. Additionally, some factors contributing to high egg prices, such as inflation and increased production costs, may be beyond the government’s immediate control.

President Donald Trump, who campaigned on promises to lower food prices, is facing pressure from lawmakers to act. However, no specific plan has been announced to address the egg price crisis, but NEC Director Kevin Hassett has signaled that a plan is coming, which was released on Sunday.

Iowa Secretary of Ag Weighs In on The H5N1 Battle, Vaccine Potential And Trade Sensitivities

Wed, 29 Jan 2025 13:53:38 GMT

Eggs continue to be a hot topic in the news as supplies are down, prices are up – and expected to go even higher – and consumers are understandably concerned.

At the center of the issue, fanning the on-going problem for poultry and dairy producers as well, is the Highly pathogenic H5N1 avian influenza A virus (HPAI H5N1).

AgriTalk Host Chip Flory broached the topic with Iowa Secretary of Agriculture Mike Naig on Tuesday.

At the heart of their conversation was a two-part question – how does the U.S. address the virus and, in the process, prevent any potential negative ramifications on trade?

Naig says the federal government is taking what he described as a three-legged stool approach to addressing the problem in both industries.

He described the three legs of the stool as being USDA’s Animal and Plant Health Inspection Service (APHIS), individual state animal health officials and industry.

“We work very closely with APHIS on this, meaning that they’re the ones that are providing the indemnity payments to producers. They are providing the disposal and cleanup assistance, but they must work in close collaboration with the states and state animal health officials,” Naig says. “And then, of course, you’ve got to have the third leg, which is industry.”

Biosecurity Measures
Naig noted that while the virus hit the poultry industry hard in 2015, it struck even harder in 2024.

“It’s not just in the Midwest or West, it’s been really all across the country now, affecting the egg laying industry, broilers and turkey production,” Naig says.

A significant positive, Naig says, is that biosecurity measures in the poultry industry appear to be preventing farm-to-farm spread. “The industry continues to get high marks for that, which wasn’t the case in 2015, which was so devastating because we didn’t have those strategies in place.”

“I believe, and our experience has been, that our USDA partners in this regard have been very strong,” he adds.

As Naig addressed the three-legged stool approach the U.S. is taking to addressing the virus in dairy, he says the three partners have more work to do.

“Frankly, there’s been a lot of criticism to share around the three legs, if you will, on how states have reacted, or how strongly USDA should have reacted, and what the industry is doing to try to contain that virus. So, I would say on the dairy side of things, it’s a different story (than in poultry). There’s a lot more work that’s yet to be done to even understand how that virus is impacting those (dairy) herds.”

What Is The Role For Vaccines?
Flory asked Sec. Nagy whether he believes a vaccine could be part of the solution to the virus or whether that would set up too many trade barriers. Flory also asked whether the virus is stable enough for a long enough period of time for a vaccine to be developed that would work effectively.

Both are questions the U.S. is grappling with as it tries to get ahead of the virus in dairy and poultry.

Earlier this month, Reuters reported the U.S. will rebuild a stockpile of avian influenza vaccines for poultry that match the strain of the virus circulating in commercial flocks and wild birds, citing the Department of Agriculture.

Naig told Flory that he believes a vaccine could be developed, with regard to poultry specifically, and its use negotiated into trade agreements.

“Those are challenges, and yet those are things that can be worked on and can be done, but it’s not easily done. I would want to put a flag there,” Naig says.

“I’m supportive of developing … we should try to figure out whether this can be an effective tool. If you’re in the broiler business or if you’re in the turkey meat business or if you’re in the egg business or maybe you’re in the genetics business, those are very different in terms of how you view that vaccine.”

Naig explains part of the different viewpoints on vaccine use have to do with the difference between poultry business segments.

“We need to recognize that those sectors are different in how they’ll view and potentially use a vaccine,” Naig says.

“Don’t treat them all the same. It’ll make way more sense for some than others.”

Naig did not weigh in on vaccine development for the dairy industry specifically.

APHIS Answers Call to Protect Animal Agriculture

Thu, 16 Jan 2025 21:00:12 GMT

Despite facing many challenges, including the continued response to highly pathogenic avian influenza, USDA’s Animal and Plant Health Inspection Services (APHIS) worked to protect the health and value of America’s agricultural and natural resources.

“2024 was a year that confronted APHIS with new challenges. It was a year that forced us to find new and creative solutions to animal and plant health threats,” says Michael Watson, administrator for APHIS, in the 2024 Impact Report.

Here are a few highlights from the 2024 Impact Report surrounding animal agriculture:

Confirmed the first detection of HPAI H5N1 in a dairy herd in March 2024, and subsequently identified, investigated, and responded to H5N1 detections in livestock in over 860 herds across 17 states. APHIS issued two federal orders, implemented a producer support program, set up a voluntary monitoring and surveillance program for interested producers, and developed a national bulk milk testing strategy to help states protect the health of their dairy herds.
- Opened new market access for American agricultural exports, including U.S. rice to Ecuador, Texas grapefruit to South Korea, and California peaches and nectarines to Vietnam. APHIS also opened markets for U.S. live cattle, day-old chicks, and hatching eggs to Mozambique and beef and bone meal to Ecuador and Peru.
- Worked with regional partners in Central America to implement a multilateral response to the New World screwworm outbreak, increasing production of sterile flies weekly from 20 million to 90 million. These efforts, combined with rigorous surveillance and livestock inspections, protected U.S. borders from this devastating pest.
- Provided assistance to livestock producers on more than 123,000 occasions, including outreach and direct control activities to protect livestock from predation through a combination of techniques and tools. As much as possible, we responded using nonlethal methods like range riding, fladry, fencing, and husbandry practices.
Continued an emergency program to address nationwide detections of highly pathogenic avian influenza (HPAI). Since the outbreak began in February 2022, we have confirmed the virus in over 1,300 poultry premises across the nation and supported affected producers through depopulation, disposal, and indemnification programs.
Protected American agriculture from harmful plant pests and foreign animal diseases by intercepting 289,855 prohibited agricultural items and 3,008 quarantine-significant pests during baggage inspections. These inspections involved more than 16.7 million passengers bound for the U.S. mainland from Hawaii and Puerto Rico.

Unapproved Use of Aspirin in Dairy Cattle Prompts Reminder for Pork Industry

Tue, 14 Jan 2025 18:00:52 GMT

The increased use of aspirin (acetylsalicylic acid) to treat pyrexia and pain in dairy cattle infected with highly pathogenic avian influenza (HPAI) H5N1 prompted FDA to issue a warning to producers and veterinarians in October. Previously, FDA had stated that aspirin use was of low regulatory concern. However, due to its increased use because of H5N1, FDA has shifted its stance.

“The U.S. Food and Drug Administration understands that veterinarians and dairy farmers may be treating lactating dairy cattle for pyrexia and pain with aspirin and wants to clarify that there are no FDA-approved aspirin products for use in cattle,” FDA said in a letter to veterinarians . “There are FDA-approved products for controlling pyrexia and pain in lactating dairy cattle that are safe, effective, and have established milk and meat withdrawal periods.”

How Does This Affect the U.S. Swine Industry?
The same regulations that guide the use of aspirin in dairy cattle also guide its use in swine, reminded Locke Karriker, DVM, professor at Iowa State University College of Veterinary Medicine and American Association of Swine Veterinarians (AASV) president-elect, in a recent Swine Health Information Center/AASV webinar.

“Currently, those regulations mean that there is no legal pathway to use aspirin in swine and it should be avoided,” Karriker says.

Under the Animal Medicinal Drug Use Clarification Act (AMDUCA), veterinarians may use only FDA-approved human or animal drug in food-producing species under specific conditions in an extra-label manner. The extra-label use of unapproved drugs in food-producing species is prohibited.

All FDA-approved animal products are required to carry one of the following statements on the label:

“Approved by FDA under NADA # XXX-XXX” (for brand name animal drugs), or
“Approved by FDA under ANADA # XXX-XXX” (for generic animal drugs).

With no legal pathway to use true aspirin in swine, experts are looking into other potential treatments and other nonsteroidals and how they may be evaluated.

“The industry, veterinarians and university-based clinical scientists are working to develop alternatives to aspirin use while exploring the development of products that contain aspirin and conform to regulatory requirements,” Karriker says. “This includes cooperation among the professional veterinary organizations for bovine, poultry and swine medicine as well as dialog with the FDA directly.”

Dusty Oedekoven, DVM, chief veterinarian for the National Pork Board, says this situation is a good example why involvement of a licensed, accredited veterinarian is important in providing timely care for animals while ensuring regulatory compliance and food safety.

“My recommendation to producers is to consult with your herd veterinarian regarding the use of any animal health products, including aspirin products (acetylsalicylic acid),” Oedekoven says.

Karriker adds that depending on the case context and clinical signs, there may be several options that do have a legal status.

Government Designates $103 Million to Monitor Avian Influenza in Farmworkers

Mon, 06 Jan 2025 14:46:10 GMT

The U.S. Department of Health and Human Services (HHS) announced on Jan. 3 that it will award $306 million to continue its H5N1 Avian Flu response. Although the Centers for Disease Control and Prevention’s assessment of the risk of avian influenza to the general public remains low, USDA and HHS plan to collaborate with federal, state, local, industry and other stakeholders to protect human health, animal health and food safety, a release said.

“While the risk to humans remains low, we are always preparing for any possible scenario that could arise. These investments are critical to continuing our disease surveillance, laboratory testing, and monitoring efforts alongside our partners at USDA,” Secretary Xavier Becerra said in a release. “Preparedness is the key to keeping Americans healthy and our country safe. We will continue to ensure our response is strong, well equipped, and ready for whatever is needed.”

Administration for Strategic Preparedness and Response said it will award approximately $183 million in additional funding for regional, state and local preparedness programs:

$90 million to the Hospital Preparedness Program (HPP)
$10 million to the National Emerging Special Pathogens Training and Education Center (NETEC)
$26 million to the Regional Emerging Special Pathogen Treatment Centers (RESPTCs)
$43 million to the Special Pathogen Treatment Centers (SPTCs) Avian Influenza Preparedness and Response Activities
$14 million to replenish equipment and supply caches for the National Disaster Medical System (NDMS)

CDC will award approximately $111 million in funding for additional enhancements to our ability to monitor H5N1 at the local, state and national levels:

$103 million to jurisdictions for increased monitoring of individuals exposed to infected animals, testing, and outreach to high-risk populations (such as livestock workers)
$8 million to manufacture, store, and distribute additional influenza diagnostic test kits for virologic surveillance

National Institutes of Health will award approximately $11 million in funding for additional research into potential medical countermeasures for H5N1:

$11 million to the Centers for Excellence for Influenza Research and Response contracts

New Zealand Reports First Case of HPAI

Mon, 02 Dec 2024 19:45:35 GMT

Biosecurity New Zealand has placed strict movement controls on a commercial rural Otago egg farm, the Ministry for Primary Industries reports, after testing confirmed a highly pathogenic strain of avian influenza (HPAI) in chickens that has likely developed from interactions with local waterfowl and wild birds.

“Tests from the Mainland Poultry managed farm have identified a high pathogenic H7N6 subtype of avian influenza. While it is not the H5N1 type circulating among wildlife around the world that has caused concern, we are taking the find seriously,” Biosecurity New Zealand deputy director-general Stuart Anderson, said in the release.

Testing shows it is unrelated to a H7 strain that was identified in Australia earlier this year. Experts believe this case may have occurred as part of a spillover event, where foraging laying hens were exposed to a low pathogenic virus from wild waterfowl.

“Low pathogenic viruses are present in wild birds here, especially waterfowl like ducks, geese, and swans, and the virus can mutate on interaction with chickens,” Anderson said. “It is important to note that the strain found on this farm is not a wildlife adapted strain like H5N1, so we believe it is unlikely to be transmitted to mammals.”

The report says there have been no reports of other ill or dead birds on other poultry farms. There are no human health or food safety concerns, so it is safe to consume thoroughly cooked egg and poultry products, the release said.

Quick action had been taken in co-operation with Mainland Poultry and a restricted place notice issued, Anderson explained in the release.

“Test results late last night confirmed the strain, but we already had restrictions in place and expert biosecurity staff on site, with more arriving today. Mainland Poultry took the right steps by reporting ill birds in one shed on the property and locking that building down as testing continued,” he said. “We will move quickly, with Mainland Poultry, to depopulate birds on the remote property, and we’ve placed a 10-kilometre buffer zone around it alongside the restrictions preventing movement of animals, equipment, and feed. We aim to stamp this out like we did with infectious bursal viral disease that affected chickens in 2019.”

John McKay, chief executive of Mainland Poultry, manages the free-range farm. He says the farm is committed to taking quick action.

“We have been preparing for an event like this for some time, knowing that low pathogenic avian influenza is already present in New Zealand wild birds,” McKay said in the release. “Fortunately, this is not the H5N1 type that has caused concern for wildlife in other parts of the world. International experience with avian influenza has shown us this particular strain (H7N6) can be eradicated quickly and successfully.”

Biosecurity New Zealand will work closely with industry partners to limit possible impacts to trade.

H5N1 Risk to Swine Research Program Proposals Needed

Wed, 06 Nov 2024 22:18:40 GMT

The Swine Health Information Center (SHIC) is partnering with the Foundation for Food & Agriculture Research and the Pork Checkoff to fund a $4-million research program to enhance prevention, preparedness, mitigation and response capabilities for H5N1 influenza in the U.S. swine herd.

H5N1 influenza, an emerging disease identified as a priority for the U.S. pork industry, poses a risk due to ongoing outbreaks in poultry and a growing number of diverse mammalian species susceptible to infection, SHIC said in a release. The unprecedented 2024 H5N1 outbreak impacting dairy herds across the U.S. fuels the urgency for greater understanding and information, along with the recent discovery of the virus in a single backyard pig in Oregon on Oct. 30.

“This diagnosis certainly reminds us of the necessity for diligent, effective, and consistent biosecurity measures on all pig farms to safeguard the health of our herds. SHIC continues to prioritize the mitigation of H5N1 and other emerging disease risks to US swine through our disease prevention, preparedness and response infrastructure to maintain the health of U.S. swine,” says Megan Niederwerder, executive director of SHIC. “Importantly, no animals on the Oregon farm were intended for the commercial food supply and U.S. pork remains safe for consumers.”

Research priorities for H5N1 are designed to further strengthen U.S. swine industry prevention and preparedness as well as inform response efforts should H5N1 be introduced into the commercial swine herd.

Submission Information
Proposal submissions are encouraged from qualified researchers for funding consideration to address H5N1 risk to swine research priorities described in the detailed Request for Research Proposals found here along with the instructions for completion and submission, including topic areas of 1) vaccines, 2) clinical presentation, 3) mammary transmission, 4) surveillance, 5) introduction risks, 6) caretakers, 7) biosecurity, 8) pork safety, 9) production impact and 10) pig movements.

Individual awards are capped at $250,000, however, proposals may exceed cap if sufficient justification is provided, the release said. Matching funds are encouraged but not required; the funding cap applies to only those funds requested from SHIC/FFAR/NPB. All projects should strive to have a high impact, show value to pork producers, and have pork industry-wide benefit.

Collaborative projects including the pork industry, allied industry, dairy or poultry industries, academic institutions, and/or public/private partnerships are highly encouraged. Projects demonstrating the most urgent priorities and timeliness of completion, providing the greatest value to pork producers, and showing efficient use of funds will be prioritized for funding. Projects are requested to be completed within a 12-to-18-month period with sufficient justification required for extended project duration.

The deadline for proposal submission is 5 p.m. CT on Dec. 31. For questions, please contact Dr. Megan Niederwerder at mniederwerder@swinehealth.org or 785-452-8270 or Dr. Lisa Becton at lbecton@swinehealth.org or 515-724-9491.

Oregon Identifies 3 Human Cases of Avian Influenza in Farm Workers from Washington State

Fri, 01 Nov 2024 14:21:40 GMT

Avian influenza (bird flu) has infected three more people from Washington state after they were exposed to poultry that tested positive for the virus, according to health authorities in Washington and in Oregon, where the human cases were identified.

A total of 39 people have tested positive in the U.S. this year, including nine from Washington, as the virus has infected poultry flocks and spread to more than 400 dairy herds, federal data show. All of the cases were farm workers who had known contact with infected animals, except for one person in Missouri.

The people from Washington cleaned facilities at an infected chicken farm after birds were culled to contain the virus, the Washington State Department of Health said in an email on Thursday.

Officials tested workers who had symptoms, including red eyes and respiratory issues, and those with potential exposure to the birds, the department said. People with symptoms were told to isolate and given antiviral treatment, it added.

Oregon identified the three new cases after the people traveled to the state from Washington while infected, the Oregon Health Authority said in a Thursday statement. They have since returned to Washington, where public health staff are monitoring them, according to the statement.

There have been no infections among people living in Oregon and is no evidence of human-to-human transmission, the Oregon Health Authority said. It said the risk for infection to the general public remains low.

Since 2022, the virus has wiped out more than 100 million poultry birds in the nation’s worst-ever bird flu outbreak.

H5N1 bird flu was confirmed in a pig on a backyard farm in Oregon, the first detection of the virus in swine in the country , USDA said on Wednesday.

Influenza Expert Gets Real About the H5N1 Risk to Your Swine Herd

Thu, 31 Oct 2024 22:11:28 GMT

Is influenza a greater concern to pigs and people in light of the Oct. 30 USDA announcement that H5N1 was detected for the first time ever in a pig from a backyard Oregon farm? If so, how?

Andrew Bowman, DVM, one of the country’s top swine influenza experts, joined The PORK Podcast to answer that question and more during a special report on H5N1. A professor in the Department of Veterinary Preventive Medicine at The Ohio State University, he is well known for his expertise in swine production medicine, veterinary public health and epidemiology.

“Across the swine industry, we routinely deal with influenza, so we’re pretty well versed in flu,” Bowman says. “But this adds a whole other character to the scene that we really don’t want and reassorting with the flu viruses we already have.”

This isn’t just something that will go away, he adds. This is a topic that’s becoming a bigger issue across the ‘entire proverbial barnyard.”

“Poultry has been dealing with this problem for a while. Dairy, this year, has joined the influenza game. Pigs have had our own endemic strain. The idea that high-path might be affecting pigs as well, and even if not, is a good warning sign the threat is there,” he says.

It’s an important topic for the pork industry to think about, Bowman points out. Oregon might be miles from your farm, but the threat isn’t going away. So, how are you trying to keep diseases such as influenza out of your herd with biosecurity protocols?

“We need to work together. I don’t think there’s much finger pointing left in the flu world. We’re all on the same bus, and we need to figure out how we manage this,” Bowman says. “Granted, it will be different in different species, but this is a problem everyone’s having to deal with.”

USDA Reports First H5N1 Detection in Swine

Wed, 30 Oct 2024 19:05:00 GMT

USDA announced on Oct. 30 the first reported case of H5N1 in a pig in an Oregon backyard farm. It’s important to note there is no concern about the safety of the nation’s pork supply as a result of this finding, USDA said. This farm is a non-commercial operation, and the animals were not intended for the commercial food supply.

“The confirmed case in Oregon poses no threat to consumer health or food safety; properly handled and cooked pork products remain safe for consumption,” Bryan Humphreys, National Pork Producers Council (NPPC) CEO said in a statement. “The entire pork industry remains committed to safeguarding food safety and human and animal health.”

The case was discovered on a backyard farm that includes a mix of poultry and livestock, including swine. The Oregon Department of Agriculture announced on Friday, Oct. 25, that poultry on this farm represented the first H5N1 detection in Crook County, Oregon. On Tuesday, Oct. 29, the USDA National Veterinary Services Laboratories also confirmed one of the farm’s five pigs to be infected with H5N1, marking the first detection of H5N1 in swine in the U.S., USDA reports.  

“The livestock and poultry on this farm shared water sources, housing, and equipment; in other states, this combination has enabled transmission between species. Although the swine did not display signs of illness, the Oregon Department of Health and USDA tested the five swine for H5N1 out of an abundance of caution and because of the presence of H5N1 in other animals on the premises,” USDA wrote.

The swine were euthanized to facilitate additional diagnostic analysis. Although test results were negative for two of the pigs, and test results are still pending for two others.  
The farm has been quarantined to prevent further spread of the virus. Other animals on the farm include sheep and goats that remain under surveillance.  

“USDA’s National Veterinary Services Laboratories (NVSL) has conducted genomic sequencing of virus from the poultry infected on this farm, and that sequencing has not identified any changes to the H5N1 virus that would suggest to USDA and CDC that it is more transmissible to humans, indicating that the current risk to the public remains low,” USDA wrote.

H5N1 detections include viral genome sequencing to provide additional information of interest to medical professionals and the research community to improve understanding of the virus. Genetic sequencing for these samples is underway, but results may be inconclusive due to low viral levels in the samples, USDA said.   

Pork Producers Practice Biosecurity to Protect Pigs
Biosecurity is critical to eradicating H5N1 and other viruses. Not only does biosecurity protect the health of livestock, but it also protects the health of farmworkers and their families. For more information on protecting farmworkers, visit the CDC’s website .

The pork industry has worked alongside USDA’s Animal and Plant Health Inspection Service (APHIS) since 2009 to carry out the swine influenza surveillance program to identify influenza viruses circulating in swine, proactively detect reassortment viruses that could impact public health, and gain knowledge to contribute to improved animal health diagnostics and vaccines, NPPC pointed out in a statement.

“Pork producers have always been proactive and diligent about implementing biosecurity plans as part of their daily production practices to assure animals wellbeing and food safety,” Lori Stevermer, NPPC president and Minnesota pork producer said. “This detection serves as a reminder for producers of all sizes to understand and address influenza virus risks.”

What’s Next?
USDA recently approved two vaccine field safety trials for vaccine candidates designed to protect dairy cows from H5N1, and continues to explore vaccine options for other species.   As USDA takes additional steps to protect the health of livestock, it will continue to work closely with CDC to protect the health of people and FDA to protect the safety of the food supply.

“These collective, collaborative efforts have helped protect farmworkers and farmers, the health and welfare of livestock animals, and reaffirmed the safety of the nation’s food supply. The U.S. government remains committed to addressing this situation with urgency,” USDA said.

Animal Health Experts Open Up About Future Disease Preparedness

Thu, 26 Sep 2024 21:20:39 GMT

With recent outbreaks of H5 influenza in poultry and dairy populations, what is the impact on “secure” plans for the livestock sector?

During the National Association of State Departments of Agriculture 2024 Annual Meeting, the Animal Agriculture Policy Committee hosted a panel with Danelle Bickett-Weddle, veterinary and public health consultant and Preventalytics owner; Jim Roth, Clarence Hartley Covault Distinguished Professor at Iowa State University’s College of Veterinary Medicine; and Carol Cardona, Pomeroy Chair in Avian Health at University of Minnesota’s College of Veterinary Medicine.

Panelists shared current efforts to safeguard the animal agriculture industry against foreign and emerging animal disease threats. H5 influenza continues to pose a threat to animal health in a few species. Because of this panelists explained how the livestock sector is working toward strengthening biosecurity and sustainability measures and enhancing collaboration among state and federal agencies, industry stakeholders and farmers.

“H5 influenza viruses have spread across the globe and now the U.S. where they have become endemic in wild bird populations,” Cardona said in a NASDA release. “Annual incursions of the virus into domestic animals are likely to continue because there is a continuous source from this reservoir. Animal production systems need to live with a constant threat and prevent infections and maintain reliable protein sources for the consumer. That’s where the Secure Supply plans can help.”

Outbreaks underscore the need for robust and adaptable secure plans to mitigate the spread of disease and minimize supply chain disruptions. The panel urged livestock producers to strengthen biosecurity methods and enhance awareness. Roth emphasized the threat to swine populations and the need for the Secure Pork Supply plan in the event of the current H5 influenza mutating to infect swine populations.

“Swine are commonly infected with influenza,” Roth said in a release. “Commercial swine producers and swine veterinarians are very aware of the H5 influenza in poultry and dairy cows and are monitoring swine to ensure that they are not infected and to be prepared to respond quickly. The biosecurity and surveillance developed for the Secure Pork Supply plan could be very useful in the event of the H5 influenza virus moving into pigs.”

For affected producers, panelists shared efforts on recovery, resources and federal support.

“When H5 influenza was diagnosed in dairy cattle, the enhanced biosecurity resources from the Secure Milk Supply Plan were promoted as prevention practices,” Bickett-Weddle said in the release. “While SMS was developed for foot-and-mouth disease, the concepts of stopping exposure through cattle, people and vehicle movements apply to H5.

Get the Facts Straight on Highly Pathogenic Avian Influenza

Thu, 26 Sep 2024 19:12:14 GMT

Updated as of 4.10.24

Now that the mystery illness impacting dairy herds in multiple states has been revealed as the same strain of influenza virus [Influenza A (H5N1)] that has been impacting the U.S. poultry flock, pork producers are asking a lot of questions. Is this strain transmittable to pigs? Should livestock producers with cattle and pigs be concerned about cross-species transmission?

Those are all important questions, but understanding influenza is the best place to start, says National Pork Board chief veterinarian Dusty Oedekoven.

“Highly Pathogenic Avian Influenza (HPAI) is influenza. HPAI is an official term defined by the severity of the mortality rate in poultry,” he explains.

Within strains of influenza A, the naming convention goes by two proteins on the outer surface of the virus: hemagglutinin (H type) and neuraminidase (N type). Typically, HPAI is of the H5 or H7 types, but there are many other possibilities as there are 18 hemagglutinin types and 11 neuraminidase types, he explains.

“Not all of those occur in poultry, not all of those occur in pigs, and not all of those occur in humans,” Oedekoven clarifies. “But the term highly pathogenic applies to poultry.”

He believes the reason it’s making headlines as HPAI is because it’s the same strain, H5N1, or similar strain that has been found recently in poultry where they have designated it as HPAI.

“Maybe that’s a narrow thing to tease apart,” he points out. “But in my mind, I hope we can separate that a little bit. This is influenza A virus.”

Influenza A viruses affect many warm-blooded animals, including birds and mammals. That’s nothing new, Oedekoven says. Influenza A viruses have been identified in cattle in the past, as well as swine and birds.

“If we think about influenza in domesticated species and humans, we are typically looking at the cycle between humans and pigs,” he says. “Pigs become amplifying hosts of influenza A viruses and the mixing vessel for different types of viruses, as are birds. Birds can get multiple viruses and those viruses mutate within the bird, and new strains evolve. That’s how we have new strains of the virus that emerge and become different strains.”

And that’s why receiving the annual flu vaccine is so important, he adds.

“It’s likely the vaccines we got last year were designed for a different strain than what we’re looking at this year because the virus reassorted and it’s slightly different. Scientists predicting which strain we might be dealing with for the vaccine are right sometimes, and sometimes they miss the mark a little and you may see more influenza in a given year,” he says.

Fact #1: The threat of influenza virus infection in people and pigs is ever present.

Oedekoven says he has not heard of the H5N1 strain being identified in pigs at this time.

“We know pigs are susceptible to influenza A viruses, and swine influe-nza is not uncommon in the U.S. We see outbreaks of routine swine influe-nza fairly frequently,” he says. “We don’t know if there’s any special higher risk of disease or illness or mortality for pigs due to this virus strain than any other swine influenza strain we have.”

The key is diligent observation. If producers see signs of illness in their pigs, Oedekoven urges them to contact their veterinarians.

On the same hand, if they see signs of respiratory illness or flu-like symptoms in people, seek advice from healthcare providers.

Influenza A viruses are common in people, just like they are pigs. Influenza viruses are constantly changing and reassorting.

“The threat of influenza virus infection in people and pigs is ever present. It’s why healthcare providers recommend people get annual influenza vaccines to prevent against new strains of the virus that are emerging all the time,” he says.

This doesn’t represent an elevated threat, Oedekoven adds.

“It’s recognition of a threat we know is there,” he says. “Influenza viruses exist and circulate in people all the time.”

Good sanitation and hygiene are important. If employers have workers who are ill with influenza signs, don’t let them come to work because they could potentially spread that disease to the pigs, which could cause more spread to other humans.

Fact #2: There’s no evidence to support a higher risk of influenza infection from cattle to pigs than exists otherwise.

“We’re not even sure yet to what extent this strain of influenza may be transmitted from cattle,” he says.

USDA reports bovine influenza A virus (originally referred to as HPAI in many reports) in dairy cattle was first identified in samples that included unpasteurized milk from one dairy farm in Texas and two in Kansas, as well as an oropharyngeal swab from another dairy in Texas. The virus was first confirmed in one Texas herd on March 21 by Iowa State University’s diagnostic lab that was helping Texas labs process samples more quickly. Affected farms also reported finding deceased wild birds on their properties.

“Most waterfowl and wild bird species can carry influenza viruses, but usually they don’t die from it. They are good carriers of it and can become infected and produce high levels of the virus and spread it. It’s always a good biosecurity practice to keep birds away from your pigs,” he says.

Remain Vigilant
Megan Niederwerder, executive director of the Swine Health Information Center (SHIC), encourages producers to keep close tabs on biosecurity protocols to reduce risk of pathogen exposure from wildlife.

“As part of the Swine Health Information Center’s Standardized Outbreak Investigation Form, there are several hazards associated with wild birds that can be proactively considered to enhance biosecurity,” Niederwerder explains.

Examples include surface water, wild bird access to inside swine barns, equipment stored outside, compost piles, mortality disposal boxes, open feed bags, open feed bin covers and feed spillage fed to pigs, she says.

“It is important to clean and disinfect tools and equipment with potential exposure to wildlife prior to utilizing inside facilities housing pigs,” Niederwerder says.     

Prompt investigation is key, Oedekoven says. This helps veterinarians and producers handle disease challenges better. USDA notes additional testing is underway, including genome sequencing, to characterize the strain(s) associated with the detections.

Spread the Word

Pork producers play an important role in disseminating truth, Oedekoven says. According to the Centers for Disease Control and Prevention, influenza has not been shown to spread through eating properly handled pork.

“You can’t get influenza from eating or handling pork,” Oedekoven emphasized. “There’s not a risk of acquiring influenza that way. The way that it is transmitted is through aerosolization and direct contact between infected animals, including humans.”

BREAKING: Mystery Illness Impacting Texas, Kansas Dairy Cattle is Confirmed as Highly Pathogenic Avian Influenza Strain

Meat Institute: Properly Prepared Beef is Safe to Eat; HPAI is not a Food Safety Threat

Rare Human Case of Bird Flu Confirmed. Officials Believe it Began on Texas Dairy

Thu, 26 Sep 2024 19:07:46 GMT

Just a week after discovering that Highly Pathogenic Avian Influenza, also known as bird flu, was the cause of illness for several dairy herds throughout the Texas Panhandle, New Mexico and Kansas , the Texas Department of State Health Services (DSHS) is now reporting that a human case of avian influenza A(H5N1) virus has been confirmed in Texas. The case was identified in a person who had direct exposure to dairy cattle presumed to be infected with the disease.

The patient, who experienced eye inflammation as their only symptom, was tested for flu late last week with confirmatory testing performed by the Centers for Disease Control and Prevention over the weekend. Currently, the patient is being treated with the antiviral drug oseltamivir. The DSHS reports that the human case does not change the risk for the general public, which still remains low.

According to the CDC, this is the second human case of H5N1 flu in the U.S. and the first linked to an exposure to cattle. Symptoms can include a fever, cough, sore throat, runny or stuffy nose, headaches, fatigue, eye redness, shortness of breath, diarrhea, nausea, vomiting, or seizures. The illness can range from mild to severe, and health care providers who come across someone who may have the virus should “immediately consult their local health department,” according to the alert.

“The risk to the general public is believed to be low; however, people with close contact with affected animals suspected of having avian influenza A(H5N1) have a higher risk of infection,” the alert said.

While the disease is new to the dairy industry, the U.S. Department of Agriculture says there is no safety concern to the commercial milk supply. Consumer health is also not at risk, the department said. The milk from impacted animals is being dumped or destroyed and will not enter the food supply.

“Milk from impacted animals is being diverted or destroyed so that it does not enter the human food supply,” agencies said. “In addition, pasteurization has continually proven to inactivate bacteria and viruses, like influenza, in milk. FDA’s longstanding position is that unpasteurized, raw milk can harbor dangerous microorganisms that can pose serious health risks to consumers, and FDA is reminding consumers of the risks associated with raw milk consumption in light of the HPAI detections.”

The virus was detected in dairy herds in Texas and Kansas last week and has since spread to additional herds in at least five states, all of which include:

Texas
Kansas
New Mexico
Idaho
Michigan

This leads some scientists to believe that the virus may be spreading cow-to-cow.

Texas officials are guiding affected dairies about how to minimize workers’ exposure and how people who work with affected cattle can monitor for flu-like symptoms and get tested.

In addition, officials are strongly advising dairy producers to use all standard biosecurity measures. They note it’s important for producers to clean and disinfect all livestock watering devices and isolate drinking water where it might be contaminated by waterfowl. Farmers are also being asked to notify their herd veterinarian if they suspect any cattle within their herd are displaying symptoms of this condition.

“Unlike affected poultry, I foresee there will be no need to depopulate dairy herds,” says Texas Agriculture Commissioner Sid Miller. “Cattle are expected to fully recover. The Texas Department of Agriculture is committed to providing unwavering support to our dairy industry.”

HPAI Now Detected on Ohio Dairy: Strange Bird Flu Concerns See Growth

Thu, 26 Sep 2024 19:03:23 GMT

Ohio has become the sixth state where dairy cattle have tested positive for highly pathogenic avian influenza (HPAI), also known as bird flu. A recent news release from the Ohio Department of Agriculture (ODA) reports presumptive positive results from dairy cows in Wood County.

According to officials, the cows arrived in Wood County on March 8 from a dairy in Texas. That dairy later reported a confirmed case of HPAI. The Ohio dairy operation alerted state officials when the livestock began showing signs of illness. State officials are awaiting confirmation from the U.S. Department of Agriculture.

“We have official confirmation that we do have a case at a dairy in Wood County of HPAI, which is an influenza,” says ODA Director Brian Baldridge. “We’ve been working with this in the poultry industry for about the last two-and-a-half years and it has found its way into the dairy industry. We are working diligently with the dairy, with their vets and with our Animal Health division and our state veterinarian, Dr. (Dennis) Summers, on this issue.

According to the USDA, HPAI has now been detected in five other states, including:

Texas
Kansas
New Mexico,
Idaho
Michigan

“Clinically sick dairy cattle from affected herds range from 1% to 20%, with an average of 10% of the milking herd affected. There are no confirmed reports of death loss in dairy cattle directly attributed to these detections. Most sick cows begin recovering within a few days.”

“Federal and state agencies continue to conduct additional testing from sick animals and in unpasteurized clinical milk samples from sick animals, as well as viral genome sequencing, to assess whether HPAI or another unrelated illness may be underlying any symptoms,” the ODA reports.

The agency notes that clinically sick dairy cattle from affected herds range from 1% to 20%, with an average of 10% of the milking herd affected. Currently, there are no confirmed reports of death loss in dairy cattle directly attributed to these detections with most sick cows recovering within a few days.

HPAI symptoms in dairy cattle include:

Sudden drop in milk production.
Some severely impacted cows are producing thicker, more concentrated, colostrum-like milk.
Drop in feed consumption with a simultaneous drop in rumen function, accompanied by loose feces and some fever.
Impacted herds have reported older cows in mid-lactation may be more likely to be severely impacted than younger cows, fresh cows or heifers.
Some herds have reported pneumonia and mastitis.

Officials are strongly advising dairy producers to use all standard biosecurity measures. They note it’s important for producers to clean and disinfect all livestock watering devices and isolate drinking water where it might be contaminated by waterfowl. Farmers are also being asked to notify their herd veterinarian if they suspect any cattle within their herd are displaying symptoms of this condition.
