Iowa Implements 5-Mile Testing Radius to Contain Swine Pseudorabies

Fri, 01 May 2026 22:08:02 GMT

Iowa agriculture officials are working quickly to “stamp out” a confirmed case of pseudorabies (PRV) in a small commercial swine herd – the first detection of the virus in a U.S. commercial site since it was officially eradicated in 2004.

The detection, confirmed on April 30, involved five boars in a small commercial herd with less than 100 animals. While the virus has been absent from commercial herds for two decades, it remains endemic in feral swine populations, which is the suspected source of this “spillover” event.

Aggressive Containment Strategy

Following established USDA pseudorabies program standards , the affected site is being depopulated and all animals will be disposed of on-site to prevent any spread.

“The standards also require that we conduct surveillance around the site,” says Iowa Secretary of Agriculture Mike Naig. “A five-mile radius circle has been drawn around the positive site. Swine facilities within that radius will need to test for pseudorabies within the next 15 days.”

A secondary, two-mile radius circle has also been established. Farms within this inner circle must undergo a second round of testing 30 days after the original site is fully cleaned and disinfected. Naig confirmed that every producer within these zones was contacted by late Thursday.

Tracing the Source

The investigation points to a direct trace-back: the five positive boars were part of a shipment received several months ago from an outdoor “transitional” herd in Texas.

“We coordinated with the state of Texas, who began testing the herd of origin immediately on Monday,” Naig says.

The virus was caught during routine screening at the Iowa operation. While the five boars tested positive, the remaining pigs on the Iowa site tested negative. Naig notes that because there was no spread within the facility, it provides a “strong indication” that there was no spread outside the facility either.

The Science: Why PRV is a Challenge

Pseudorabies is a herpes virus , which presents unique challenges for eradication. Iowa State Veterinarian Dr. Jeff Kaisand explains that unlike many viruses that are cleared by the immune system, herpes viruses can remain dormant in the body.

“The virus can hang out and hide in the cranial nerves of the brain and the tonsil,” Kaisand says. “Pigs may recover and stop shedding, but the virus remains. Under stress, it can resurface.”

While the virus spreads primarily through nose-to-nose contact, it can also move via aerosols or contaminated equipment. Despite the risk, Kaisand emphasizes that vaccination is not currently an option for the industry.

“We are not expecting area spread, and vaccine raises trade issues,” Kaisand says. “We don’t want to vaccinate our populations and confuse natural infection with vaccine.”

Trade and Safety Outlook

Because pseudorabies is a reportable disease, the USDA has notified international trading partners, but the impact is expected to be minimal.

“There is always a potential for trade disruption, which is why we moved so swiftly,” Naig says. “We anticipate minimal, if any, short-term trade disruptions.”

Naig also stressed that the detection is not a food safety concern. Pseudorabies does not pose a risk to human health, and the U.S. pork supply remains safe.

Remain Vigilant

What producers can do is what they always should do – practice good biosecurity, Naig says.

“This is an isolated, specific incident here that has a direct trace back to this Texas farm,” Naig says. “Biosecurity is important every single day for animal health. It is important for livestock producers of all species.”

Kaisand adds that biosecurity is “protection from the unknowns, not the knowns.”

Pseudorabies (PRV) Confirmed in Iowa and Texas Commercial Swine Herds

Thu, 30 Apr 2026 22:17:16 GMT

For the first time since being eradicated in the U.S. commercial swine herd in 2004, pseudorabies (PRV) has been confirmed in herds in Iowa and Texas.

The USDA’s Animal and Plant Health Inspection Service (APHIS) National Veterinary Services Laboratories (NVSL) confirmed the detection of PRV antibodies in a small commercial swine facility in Iowa. The discovery was made through routine testing rather than pre-movement surveillance.

Traceback Confirms Texas Connection

Initial traceback efforts reveal that five affected boars in the Iowa facility originated from an outdoor production site in Texas. Subsequent testing of the Texas herd also returned positive results for the virus.

APHIS is currently collaborating with the Iowa Department of Agriculture and Land Stewardship (IDALS) and the Texas Animal Health Commission (TAHC) to expand traceback efforts and identify any further exposures.

The Feral Swine Risk

Although the commercial industry has been free of the disease for more than 20 years, PRV remains prevalent in feral swine populations across the U.S. Officials believe this detection is a result of “spillover” from wild populations.

“Pseudorabies is still found in wild or feral swine populations, which remain a potential threat of exposure for domestic pigs,” an APHIS release stated. The Texas herd involved was housed outdoors, where contact with feral swine is possible.

Impact and Symptoms

PRV is a contagious viral disease that serves as a significant threat to herd productivity:

Adult Pigs: Causes abortions, stillbirths, and respiratory issues.
Newborn Pigs: Attacks the respiratory and central nervous systems, leading to sneezing, incoordination, and high mortality rates.

While pigs are the only natural hosts, PRV can infect most other mammals—though humans, horses, and birds are considered resistant.

Official Response and Market Safety

Iowa Secretary of Agriculture Mike Naig emphasized that the state is moving decisively to eliminate the disease.

“The Iowa Department of Agriculture and Land Stewardship has spent years preparing for these types of animal health events,” Naig said. “It’s important for people to know that pseudorabies is not a food safety concern, and this virus does not pose a risk to consumers. The United States’ pork supply remains safe and secure.”

Export Implications

Despite the lack of risk to food safety, the detection could have economic repercussions. APHIS warns there may be limited, short-term impacts on the exports of U.S. swine and swine genetics as trading partners evaluate the new health status.

“Established protocols were implemented immediately in response to the incident and remain in place to safeguard the commercial swine industry,” the National Pork Producers Council said in a statement. “These steps were successfully deployed through swift action and close coordination with USDA and the IDALS. The National Pork Producers Council and Iowa Pork Producers Association support these efforts and remain committed to a coordinated response to prioritize biosecurity and prevent further occurrences.”

South Africa Receives 2 Million FMD Vaccine Doses to Combat Worst Outbreak in Years

Wed, 22 Apr 2026 16:14:18 GMT

As authorities intensify efforts to contain the South Africa’s worst foot-and-mouth disease (FMD) outbreak in years, its government announced on Wednesday that it received 2 million doses of FMD vaccine from Turkey.

The vaccine, supplied by Turkey’s Dollvet, will be distributed to provinces in the coming days based on animal population and risk, Reuters reports . An additional 4 million doses have also been ordered from Dollvet.

The government hopes to vaccinate 80% of South Africa’s national cattle herd, estimated at about 14 million. It also plans to allocate some vaccine doses to the pork industry.

Foot-and-Mouth Disease on the Rise

Reuters reports South Africa’s government has faced criticism from livestock farmers, who say they are suffering heavy losses over its handling of the outbreak, with some threatening legal action. In February, South Africa rolled out its first FMD vaccine in 20 years to ease a shortage of inoculation doses.

An additional 5 million vaccine doses have been ordered from Argentina, the article says, with delivery expected in two batches once import approval is granted by the South African Health Products Regulatory Authority.

Recent reports of the emergence and spread of the FMD SAT1 serotype are highlighting a concerning shift in the global landscape of this virus.

“For FMD virus, immunity is serotype-specific, meaning infection or vaccination against a given serotype does not confer protection against a different serotype,” says Dr. Sol Perez at the University of Minnesota in a recent Farm Journal’s PORK article .

The Challenge of Controlling FMD

FMD is severe, fast-spreading viral disease that primarily affects cloven-hoofed animals, including cows, pigs, sheep, goats and deer. According to USDA Animal and Plant Health Inspection Service , FMD is one of the most challenging animal diseases to control. Although most infected animals survive, they’re left weak and unable to produce the level of meat and milk prior to infection. FMD is not a human health or food safety threat.

FMD was first discovered in the U.S. in 1870 and eradicated in 1929. The U.S. does not have FMD at this time.

Global Expansion of Foot-and-Mouth Disease Serotype SAT1 Raises Alarms

Wed, 15 Apr 2026 17:40:47 GMT

Recent reports of the emergence and spread of foot-and-mouth disease virus (FMDV) SAT1 serotype are highlighting a concerning shift in the global landscape of this virus. The Swine Health Information Center-funded Global Swine Disease Monitoring Reports, led by Dr. Sol Perez at the University of Minnesota, have highlighted the newly affected countries in monthly publications.

“For FMDV, immunity is serotype-specific, meaning infection or vaccination against a given serotype does not confer protection against a different serotype,” Perez says in a SHIC article.

A Rapid Geographic Shift

Historically, SAT1 was maintained within endemic locations in East and Southern Africa. However, in 2025, SAT1 demonstrated a “concerning expansion” beyond its traditional geographic range, with confirmed detections of two cocirculating subtypes across Western Asia and North Africa. The increasing circulation of SAT1 poses a growing risk to previously unaffected regions, including southeast Europe and potentially beyond. As this serotype expands its geographic range, it creates additional pathways for introduction into new regions and countries, increasing the overall likelihood of transboundary spread, Perez notes.

The Immunity Gap

The primary concern for animal health officials is that FMDV immunity is serotype-specific. Current vaccination programs in many affected regions target serotypes O, A and Asia-1. Because these vaccines provide no cross-protection against SAT1, livestock populations remain effectively susceptible, research shows. This “ecological space” has allowed SAT1 to spread rapidly through populations that were previously considered protected.

Drivers of FMD Transmission

SAT1’s expansion is likely due to several factors, Perez says.

Livestock Movement: Informal cross-border movement of small ruminants, which may carry subclinical infections, is a primary driver.
Environmental Pressures: Drought and land-use changes have increased contact between wildlife reservoirs and domestic herds.
Vaccine Limitations: A lack of SAT1-specific vaccine stockpiles and gaps in surveillance have hindered rapid response efforts.

FMD Implications for the United States

Although the U.S. remains free of FMD, the expansion of SAT1 into new regions of the world increases the complexity of global risk, Perez says. The emergence of two cocirculating subtypes (topotypes SAT1/I and SAT1/III) creates more pathways for the virus to enter the U.S. via international travel, contaminated animal products, or fomites.

“These global developments underscore the need to strengthen early detection and surveillance systems, maintain stringent biosecurity measures across livestock value chains, and ensure that vaccine preparedness strategies are sufficiently flexible to incorporate emerging serotypes such as SAT1,” Perez says.

For the U.S. pork industry, this serves as a critical reminder to maintain stringent biosecurity measures and support global monitoring efforts to prevent a domestic outbreak.

When "Something is Off": Identifying the Subtle Shift of PCV2d

Fri, 03 Apr 2026 18:46:23 GMT

Porcine circovirus type 2 (PCV2) doesn’t look like the devastating ‘wasting’ disease of two decades ago that resulted in high mortality and failure to thrive. Instead, it manifests as a subtle, persistent drag on production today that leaves producers feeling like something is simply ‘off.’

New research confirms the PCV2d genotype is now ubiquitous across the U.S. industry, appearing in over 80% of clinical cases. By matching the vaccine to the dominant field strain, experts say producers can provide the most robust protection possible, effectively taking PCV2 ‘off the table’ so they can focus their resources on more complex challenges like porcine reproductive and respiratory syndrome (PRRS).

Why Modern Circovirus Doesn’t Look Like it Used To

The original PCV2 vaccines included protection against genotype “a” (the most common at the time) and “b.” What had become a major challenge for U.S. pig farmers was fading away because of the successful protection of these vaccines.

But something shifted, as viruses do. Veterinary diagnostic labs discovered less PCV2a and started finding more PCV2d.

“When they were finding PCV2d, they were not seeing the full-blown clinical signs like they saw before vaccines,” says Jana Morgan, DVM, senior key account veterinarian with Boehringer Ingelheim. “It led us to ask, what’s off? What do we need to look for? What more do we need to understand about PCV2d? We wanted to discover what PCV2d was doing to the system.”

To better understand how widespread this particular genotype was in the industry, Boehringer Ingelheim designed two studies. The first set out to determine if PCV2d was associated with particular flows or production systems from a geography perspective and system perspective. The other study sought to discover if PCV2d was actually leading to disease.

“We took two approaches to assess its distribution across the U.S. and swine-producing states,” explains Fernando Leite, DVM, associate director of technical marketing-swine at Boehringer Ingelheim. “We used oral fluids for simple detection and to see if genotype “d” was present or absent. We found that it was widely present in most swine producing states and across most of the production systems that we evaluated.”

In terms of the disease cases, the researchers followed strict criteria to validate that those pigs had clinical signs – lesions. Then, they sequenced the virus to see which genotypes were present.

“The ‘d’ genotype was present in more than 80% of the clinical cases that we investigated, and the ‘a’ genotype was present in around 15% of the cases that we investigated,” Leite says.

What Does This Mean for Vaccines?

Morgan points out there is cross protection between PCV2a and PCV2d. As the “d” genotype became more prevalent in production systems, the team worked to develop a “d” vaccine so they could have homologous protection.

“Although the ‘a’ is cross protecting, it is not doing exactly what we want it to do,” Morgan says. “We now have the ‘a’ and ‘d’ in the same bottle. It’s important to have that homologous protection to provide the most robust defense. I make sure producers understand that they will still have protection against ‘d’ if they only use the ‘a’ vaccine, but there is an economic impact by putting ‘d’ in there as well. Your production will be better, and you will decrease the clinical signs if you have ‘d’ in your system.”

When PRRS and PCV2d Mix

Recent research also indicates that PCV2d can be more virulent when combined with PRRS, Leite adds. That’s why it’s important to understand which genotype of circovirus is present on your farm.

“The more we understand, the more we can meaningfully intervene,” he says.

As PRRS also continues to evolve and become more frustrating for producers, Morgan says getting a handle on PCV2 helps.

“If we can take that piece off the table by putting a homologous vaccine in the pig that’s going to protect it to the best of its ability (whether it’s ‘a’ or ‘d’), we can start working harder to fight viruses like PRRS,” she says.

Do Diagnostics Align with a Shift in Data?

Producers are encouraged to look critically at small shifts in production numbers. If the “math is off,” diagnostics should be used to see if PCV2d is the underlying culprit, even in the absence of full-blown clinical symptoms.

“Understand what you’re seeing within your system,” Morgan says. “Yes, everyone looks at their closeout numbers. I think with PCV2d, the shift might be small. But if the diagnostics align with this small shift in production numbers, there are tools to shift that back.”

Questions about PCV2d being just in one flow or system in one area of the country have answers now, Leite says.

“PCV2d is really the predominant genotype in the industry today, across different production systems and states and locations,” he says. “Why not use the best tools that are available? If you want to optimize production, the tool is there. As always, work with your herd veterinarian to find the best strategy for your herd.”

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.

(USDA)

“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.

(USDA-ERS)

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.

Read about 5 livestock diseases that could impact U.S. food security and economic stability.

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.”

Is the U.S. Corn and Soybean Crop Getting Smaller?

Fri, 29 Aug 2025 16:48:46 GMT

From disease to drought, this 2025 crop has been thrown a curve ball late in the season. It’s also pushing the crop to maturity quicker. And with USDA projecting currently projecting a record yield and crop, many analysts say the U.S. crop is likely going backwards in terms of yield, but that doesn’t necessarily mean USDA will cut yield projections next month.

USDA’s August crop production report showed a record-high 2025/26 U.S. corn yield projection of 188.8 bu. per acre and a record-high soybean yield estimate at 53.6 bushels per acre.

But as AgWeb reported earlier this week , southern rust could take a big bite out of the U.S. corn crop this year. The disease is causing turmoil for farmers who have a large crop in the making. In some cases, a Hail Mary fungicide application at R4 up to early dent (R5) might make sense this season, say agronomists. But in severe cases, the disease can wipe out 45% of the yield potential in a field, according to the Crop Protection Network (CPN) .

Add to that fresh concerns about drought, as the latest U.S. Drought Monitor shows drought is now covering 33% of the country. When it comes to agriculture, 5% of the corn crop is now considered in drought, 11% of the soybean crop and 30% of the cotton crop.

USDA meteorologist Brad Rippey authored the Monitor this week, saying the drought picture has drastically changed over the past month.

“We’re seeing rapid expansion flash drought across the mid-south, lower Midwest into the Northeast,” Rippey says. “All of this drought has come on in just the last few weeks. At the end of July, we were virtually drought free in the Midwest, so to see these yellows and tans starting to light up, that is reflective of the overall dryness. Of course, it’s a different story in the West where we’ve got drought really deeply entrenched. But from the big picture here, a lot of focus on those developing drought areas from the mid-South into the northeast.”

The latest U.S. Drought Monitor shows how the dry August is impacting the drought picture across the country.

(U.S. Drought Monitor )

Rippey says as the taps turned off for some areas, some portions of the Eastern Corn Belt are seeing their driest August on record. He says that dryness is extending westward into parts of the southern and eastern Corn Belt.

“Agriculturally, all eyes are on the Northern Mississippi Delta into the Ohio Valley and the southern Corn Belt. A lot of those areas are receiving less than half of the normal rainfall during the month of August. A few areas have less than 25% of normal,” Rippey says. “And with those taps turning off, that is depleting topsoil moisture. We’re going to have to wait and see with crop production in September to see how the crops have handled this late dryness.”

Rippey says, on a positive note, temperatures have remained mild. So, even though the moisture has been sparse or absent, at least temperatures didn’t amplify the situation. But a dry August is still a concern.

Impact on Yield
Peter Meyer, who helped lead Pro Farmer Crop Tour in the east last week, says with the amount of dryness that’s entered the picture —and the fact that disease has exploded in many Midwest fields over the past week — he thinks the crop is getting smaller, not bigger. But that’s something that likely won’t show up until USDA factors in test weight, which will be the October report.

“I think the crop has gone backward since [Pro Farmer] Crop Tour,” Meyer says. “When I start to look at some of these numbers for the month of August, it was extremely dry in many, many areas. We’re talking the top 10 or 15 dry years out of the last 150, 160 years. So, that’s why the crop ran out of gas. It had a lot of moisture. The heat was there. It pushed a crop further and faster. I think we have an issue.”

Meyer says based on those factors, he’s dropped his yield estimate from the 183 bu. per acre he personally projected during Crop Tour last week.

“But I’m still not below 180 [bu. per acre]. I think we’re going to have an early harvest, and I think we’re going to have an earlier harvest in beans, too. That’s represents a problem here as far as the market is concerned.”

“It definitely feels like it’s going backward,” said Jim McCormick with AgMarket.net on U.S. Farm Report. “When we talk to our clients, which we have some all across the country, they are really concerned about it. Probably a little bit more in the east and the west where we’ve seen some of the driest conditions in 130 years in parts of Ohio. Is it a disaster? No, but it’s definitely taking the top end off the crop.”

Dan Basse, who’s AgResource Company’s president and founder, agrees the U.S. corn and soybean crops could be losing yield, but he warns that it may not be a dramatic cut.

“I think its going backward, but maybe not to the degree that the farmer would like,” Basse said on U.S. Farm Report. “We dropped our yield estimate from 189.2 to 187.1 [bu. per acre]. So, we’re down a skosh from USDA, but this is still a big crop. And some of the early deal data we’re getting out of Kentucky, Missouri and Kansas is above what expectations were. When you think about this crop, southern rust is a bad disease if you get it into blister or early milk stage. But when it happens at dent, you’re looking at yield losses of zero to 4%. So, let’s hope that farmers applied one application of fungicide and that kept them until the crop got in the dent. I’m hoping that’s going to limit yield losses going forward.”

USDA’s next yield revision could come Sept. 12. That’s when the agency is slated to release its latest crop production report. But if you look at USDA’s methodology in September, which is to factor in ear counts and pod counts, Basse thinks USDA could potentially raise its yield estimate next month.

“I think, in general, they tend to grow a little bit bigger,” McCormick says of USDA’s historical pattern of yield estimates from August to September. “I mean, look at last year’s analog year. The crop was big in August, it got bigger in September, then again in October before they started revising it down. It would not be a surprise that they will go bigger, but there’s gonna be a lot of pushback, like Dan said, from the disease pressure. There’s going to be a wide range on the estimate for the September WASDE when it’s all said.”

Basse adds: “I wouldn’t be surprised if USDA raises yield next month. Even on the Pro Farmer Crop Tour, it showed us record ear counts and record pod counts. Those are the two most important ingredients for the September report. Now, in October, we’ll have more to know about pod weights and ear weights. But for September, I’m kind of expecting USDA is going to be a few bushels, if you will, from the August estimate. It’s the October report that will determine how big is big.”

Senecavirus A: How Often are New Outbreaks Really Occurring?

Wed, 23 Jul 2025 01:46:17 GMT

Senecavirus A (SVA) continues to be a concern for the U.S. swine industry. This endemic disease, characterized by vesicular lesions on the snout and feet, is clinically indistinguishable to foot-and-mouth disease. This makes investigations necessary for every suspected case to rule out this foreign animal disease and places a burden on state and federal animal health agencies.

In a study led by Cesar Corzo of the University of Minnesota, researchers examined just how often new SVA outbreaks occur in breeding herds. Since a major SVA outbreak in 2015, there has been a gap in comprehensive research on how often SVA occurs across U.S. pig farms, reports the Swine Health Information Center (SHIC) .

This study, published in Animals, provides epidemiologic insights into SVA across U.S. breeding herds from January 2015 to December 2024 through analysis of data gathered from the SHIC-funded Morrison Swine Health Monitoring Project.

“Data included in this study is comprised of SVA PCR results originating from production systems participating in MSHMP as well as the type of specimen submitted and the official Premises Identification Number,” SHIC reports.

The sow population participating in MSHMP currently represents 60% of the total U.S. breeding herd. A total of 36,400 SVA PCR submissions were provided by the University of Minnesota and Iowa State University veterinary diagnostic labs (VDLs) from January 2015 to December 2024. SHIC says this robust dataset allowed for the assessment of SVA incidence, identification of temporal fluctuations, and characterization of regional patterns.

Notable findings include:
>Despite its clinical significance, the cumulative incidence of SVA in U.S. breeding herds remained low, generally less than 2.5% per year across the 10-year study period. Researchers say this suggests that while SVA continues to circulate, it affects a relatively small proportion of breeding herds annually. For sites experiencing more than one SVA outbreak, the median time interval between outbreaks was approximately 402 days, highlighting the potential for re-introductions and/or persistent circulation within herds.

>A notable temporal pattern was observed, with peak SVA incidence occurring during the third and fourth quarters of the calendar year (July to December). This suggests seasonality influences disease transmission dynamics, the researchers say. VDL reports further support this observation.

>SVA outbreaks were more frequently reported in the Midwest region. Though this finding is confounded with the high density of swine production in the Midwest, researchers say efforts to better assess disease distribution are still needed. The temporal and regional patterns suggest seasonal fluctuations and a regional disease burden, emphasizing the need for continued surveillance to better understand SVA dynamics.

>Factors like personnel and animal movement, dead animal management, and even vectors such as flies were noted in SVA transmission, reinforcing the importance of stringent biosecurity protocols.

“Overall, this study provides valuable, data-driven insights into the current epidemiology of SVA, enabling veterinarians and producers to enhance prevention and control strategies,” SHIC writes. “It underscores the ongoing need for robust and collaborative surveillance systems that integrate on-farm observations with laboratory diagnostics to provide a comprehensive picture of SVA dynamics. Specifically, the observed seasonality and regional concentration suggest opportunities for more targeted biosecurity enhancements and surveillance efforts, particularly in the Midwest during the latter half of the year.”

New World Screwworm: The Billion Dollar Battle at the Southern Border

Fri, 20 Jun 2025 18:27:59 GMT

Nearly 60 years ago, the U.S. eradicated New World screwworm (NWS). Today, the risk of reintroduction is real. So real that Ethan Lane with the National Cattlemen’s Beef Association (NCBA) says it’s not a matter of if NWS will reach the U.S. but when.

“We need to spend $300 million now to save us $8 billion down the line in eradication costs,” says Lane, who serves as the senior vice president of government affairs. “This is a marathon, not a sprint, and it’s going to take years to re-eradicate New World Screwworm and push it back to Panama.”

As the fight to keep NWS out of the U.S. ramps up, the economic impact on ranchers and the industry is top of mind.

“Successfully eradicating New World screwworm from the U.S. in 1966 cost stakeholders’ tens of millions of dollars,” says TR Lansford III, DVM, deputy executive director and assistant state veterinarian with the Texas Animal Health Commission. “The freedom from NWS provides an estimated $1 billion in direct benefits to livestock producers and $3.7 billion in benefits to the general economy annually.”

Financial Impact of NWS On Ranchers
Regular, large-scale outbreaks of NWS started occurring in the U.S. in the 1930s. According to APHIS, producer losses have reached:

1930s and 1940s — $5 million to $10 million per year
1950s and 1960s — $60 million to $120 million per year
1970s — $132.1 million per year (While the U.S. successfully eradicated the devastating pest, there have been outbreaks, primarily in Texas, since then.)

(APHIS)

Experts agree if NWS reaches the U.S., eradication today will be far more expensive due to the size of the cattle herd, speed and distance of cattle movement in commerce, and increased wildlife interfaces.

“Historically it cost tens of millions, and now it’s estimated to cost into the billions of dollars to eradicate this pest if it gets back to the U.S,” Lansford says.

Based on historical data from an isolated outbreak in Texas in 1976, per-head impact reached $452 in today’s dollars, totaling $732 million.

“[NWS] is a highly impactful foreign animal pest because it is expensive and deadly,” Lansford says. “Back in 1935, when screwworms were endemic in Texas, the state lost about 180,000 head of cattle alone in that year.”

Lansford says the industry will see decreased livestock production and increased veterinary services, medication, insecticide, labor and vehicle costs for the inspection and treatment of NWS.

“Infested wounds and/or mucous membranes and lesions created by this pest cause significant distress and damage to an animal, which can lead to chronic conditions making the animal less marketable and less productive in its lifespan,” he adds.

USDA Investment to Fight NWS
The reopening of Moore Air Base in Texas as a sterile fly distribution facility has an estimated price tag of $8.5 million. A brand new production facility, which would take two to three years to build would cost $300 to $600 million, depending on location and resources.

“That doesn’t include what it would cost to continue to operate one of those facilities,” Lansford says. “Certainly, research dollars also need to be spent to develop more effective treatments and other methods and modalities that we can use to help offset not only the infestations, but help prevent those infestations.”

USDA is also investing $21 million in the renovation of an existing fruit fly production facility in Metapa, Mexico, to further the long-term goal of eradicating NWS.

Border Closing Impacts U.S. Cattle Industry
Since May, Agriculture Secretary Brooke Rollins has suspended imports of live cattle, horses and bison from Mexico to keep NWS out of the U.S. Many U.S. cattle feeders depend on Mexican cattle to fill feedlots, especially now when the U.S. cattle inventory is at a 74-year low.

“Mexico exports, on average, 1.2 million head of cattle to the U.S. each year,” says Kathy Simmons, chief veterinarian for NCBA.

Obviously, that number will take a hit with the border closed, but Simmons says even prior to the May 11 suspension, mitigation protocols for NWS, including wound inspections, for cattle from Mexico allowed less than 25% of the usual numbers to cross the southern border each month.

As the U.S. fights to limit the impact of NWS, it’s a long-term battle, reminds Lane with NCBA.

“They’re getting those flies on that leading edge of the incursion. As I understand it, that is slowing the advance in a way that is very good to see,” he says. “The fact is, there are just so many different vectors. There are so many different ways this thing can move north, and we’re going into the hot season where flies thrive. So it’s really about slowing it, about preparing and about making sure we have the resources to meet it and push it back down as quickly as possible. But certainly everyone’s trying to focus right now on trying to hold the line as much as humanly possible.”

As Lansford has come to realize: “This pest will be one that leaves quite a mark on our economy.”

Rollins Rolls Out 5-Point Plan to Contain New World Screwworm

Wed, 18 Jun 2025 19:01:29 GMT

Today Secretary of Agriculture Brooke Rollins announced a five-pronged plan to combat New World screwworm (NWS) – a pest that would devastate ranchers if it made its way across the border.

Rollins made her announcement at the Moore Air Base facility near Edinburg, Texas. Moore was instrumental as a sterile fly production lab to rid the U.S. of NWS in the 1960s and 1970s. Hundreds of millions of flies were reared, sterilized with radiation and dropped from aircraft to eliminate the parasitic pest that preyed upon wildlife and livestock. According to a USDA spokesperson it will cost an estimated $8.5 million to get the base up and running as a distribution facility.

U.S. Secretary of Agriculture Brooke Rollins this morning launched an $8.5 million sterile New World screwworm (NWS) fly dispersal facility in South Texas and announced a plan to enhance USDA’s already robust ability to detect, control, and eliminate this pest.

According to the Texas Wildlife Association , there are currently more than 1,800 cases of livestock infestation in southern Mexico. The flies are moving north and are currently 600 miles from the south Texas border.

“We have defeated the screwworm before, and we will do it again,” Rollins says.

— Secretary Brooke Rollins (@SecRollins) June 18, 2025

Her five-pronged plan to combat NWS includes:

Stop the pest from spreading in Mexico.
Rollins plans to continue partnering with her Mexican counterparts and using sterile insect technology to stop the spread. This includes investing $21 million to produce up to 100 million additional sterile flies weekly.

“We are first enhancing the international sterile fly production and investing $21 million in renovation of an existing fly facility in southern Mexico, which will provide up to 100 million additional sterile flies every week to stop the spread,” Rollins says.

Currently, the only sterile fly facility is located in Panama. It’s jointly run by the Panamanian government and the U.S. government. USDA had previously announced its plan to invest in the retrofiting of a fruit fly facility in Chiapas, Mexico, to produce additional sterile flies.

According to the National Cattlemen’s Beef Association , “The Chiapas facility produces about 117 million flies per week, but to form an effective barrier along the U.S. southern border, we need upward of 300 million sterile flies per week.”
Protect the U.S. at all costs.
Rollins temporarily closed the southern border to live animal imports and intercepting illegally introduced livestock. USDA is working closely with Mexico to improve surveillance.

“I do believe we have met and moved into a new era of productive partnership —perhaps better than ever before — with our Mexican counterparts,” Rollins says.
Maximize our readiness.
This will be achieved by partnering with state animal health officials to update emergency management plans and stockpile therapeutics for ranchers.
Take the fight to the screwworm.
The domestic fight includes establishing a sterile fly dispersal facility at Moore Air Base. Rollins says they are exploring options for building a domestic production facility at Moore that could produce up to 300 million sterile flies per week.

“We can’t get a brand new facility up and running probably before two or three years. So, that’s why we’ve got to really focus on the today,” Rollins explains.

She also announced USDA will be hosting listening sessions in affected areas starting next week.
Innovate Our Way to Eradication.
Leverage the sound science including USDA’s Agriculture Research Service (ARS) to continue to quickly develop novel treatments, preventatives and response strategies. Rollins says this includes working with land grant universities in Texas, Arizona and New Mexico. She listed these key strategies during the press conference:
- Develop better fly traps and lures
- Provide local training
- Improve surveillance methods
- Create new response strategies

Nearly 80 lawmakers led by House Ag Committee Chair Glenn “GT” Thompson (R-Pa.) sent a bipartisan letter on Tuesday to Rollins urging immediate action and promising congressional support for the significant funding required.

The letter included this message, “When looking solely at the historical impact of NWS in Texas, USDA’s Animal and Plant Health Inspection Service (APHIS) estimates a contemporary outbreak would cost producers $732 million per year and the Texas economy a loss of $1.8 billion. Extrapolating those results to the states within the historic range of NWS pre-eradication, a contemporary outbreak of NWS could cost producers $4.3 billion per year and cause a total economic loss of more than $10.6 billion. This does not account for the possible expansion of NWS beyond the historic range.”

U.S. Congresswoman Monica De La Cruz (R-Texas) was at the announcement and recently shared in a letter to Rollins these key advantages of the Moore Air Base location:

Border proximity: The proximity to the border with Mexico is crucial for effective monitoring and control of potential incursions of invasive fly species. A facility in this region would allow for rapid response and containment, minimizing the spread of infestations into the U.S.
Existing agricultural infrastructure: The region boasts a robust agricultural sector with established infrastructure and expertise in livestock management. This existing framework would facilitate efficient integration of the sterile fly facility and streamline its operations. Additionally, Moore Air Base has operations runways equipped to distribute sterile flies.
Strategic location: Moore Air Base offers a central location for distribution of sterile flies to other areas in the southern U.S., if such a need arises. Additionally, this base was the site of a facility used in the 1960s to successfully combat NWS.
Economic impact: The establishment of such a facility would provide valuable economic opportunities for the region by generating jobs and stimulating local economies.

U.S. Congressman Ronny Jackson (R-Texas) summarized at the announcement, “This is important to the whole country. We are going to be aggressive about this, and we are going to make sure that we don’t get screwed by the screwworm.”

Chinese Scientist Accused Of Smuggling ‘Potential Agroterrorism Weapon’ Into the U.S.

Wed, 04 Jun 2025 23:10:37 GMT

Two Chinese nationals have been charged with trying to smuggle a fungus, Fusarium graminearum, into the United States.

Yunqing Jian, 33, and Zunyong Liu, 34, citizens of the People’s Republic of China, were charged in a criminal complaint with conspiracy, smuggling goods into the U.S., false statements and visa fraud.

The charges against the pair were unsealed in the U.S. Attorney’s Office for the Eastern District of Michigan, on Tuesday.

The U.S. Attorney’s Office references Fusarium graminearum online as a “dangerous biological pathogen … which scientific literature classifies as a potential agroterrorism weapon.”

Fusarium graminearum causes significant diseases in a number of U.S.-grown food crops, including corn, wheat, barley, soybeans and rice.

Diseases caused include Fusarium head blight (scab) in wheat, and two corn diseases Gibberella ear rot and Gibberella stalk rot , which can lower yield and feed quality of silage corn, according to the Crop Protection Network, a partnership of land grant universities.

Toxins the fungus produces can cause vomiting, liver damage, reproductive defects and mycotoxin-induced immunosuppression in humans and livestock, including cattle, hogs, horses and poultry.

One Scientist Arrested, One Returned To China
The 25-page criminal complaint alleges Liu tried to smuggle the fungus through the Detroit Metropolitan Airport (DMA) in July 2024, so he could study it at a University of Michigan laboratory where his girlfriend, Yunqing Jian, worked at the time.

Jian had been living in the U.S. and working at the university laboratory since 2022.

The roots of the case involving Yunqing Jian, 33, and her boyfriend, Zunyong Liu, 34, stretch back to March 2024. That is when Liu applied for a B2 tourist visa to enter the U.S.

(The Detroit News and Sanilac County Jail)

According to the criminal complaint, Jian and Liu had both previously conducted work on the fungus in China.

Officials further allege Jian received funding from the Chinese government for her research on the pathogen in China. They also claim she is a member of the Chinese Communist Party.

Jian, who was arrested by the FBI, remains in federal custody. On Thursday, her detention hearing was adjourned until 1 p.m. June 13 to allow time for a new defense attorney to get up to speed.

Liu was sent back to China last year after changing his story during an interrogation at the Detroit airport about red plant material discovered in a wad of tissues in his backpack, the FBI says.

The U.S. does not have an extradition treaty with China, which makes Liu’s arrest unlikely unless he returns.

In a statement released on June 3, the University of Michigan said it condemns “any actions that seek to cause harm, threaten national security or undermine the university’s critical public mission.”

“It is important to note that the university has received no funding from the Chinese government in relation to research conducted by the accused individuals,” the university added. “We have and will continue to cooperate with federal law enforcement in its ongoing investigation and prosecution.”

In a statement released on June 3, the University of Michigan said it condemns “any actions that seek to cause harm, threaten national security or undermine the university’s critical public mission.”

(Michigan News Source)

Boyfriend Spills Intentions To Investigators
An article in The Detroit News said Liu told investigators during an interrogation at the Detroit airport he planned to clone the different strains and make additional samples if the experiments on the reddish plant material failed, according to the government.

“Liu stated that he intentionally hid the samples in his backpack because he knew there were restrictions on the importation of the materials,” an FBI agent wrote. “Liu confirmed that he had intentionally put the samples in a wad of tissues so CBP officers would be less likely to find and confiscate them, and he could continue his research in the United States.”

Liu told investigators he planned on using UM’s Molecular Plant-Microbe Interaction Laboratory to research the biological materials, the FBI agent wrote.

“Liu stated that, while he was in the United States, he would have free access to the laboratory at the University of Michigan on some days, and that other days his girlfriend would give him access to the laboratory to conduct his research,” The Detroit News article reported.

Before preventing Liu from entering the U.S. and sending him back to China, the investigators found messages between the couple that indicate Jian previously smuggled biological material into the U.S., the FBI agent wrote.

The messages are from August 2022 and discuss smuggling seeds into the U.S.

Lawmakers Respond To The Criminal Complaint
Attorney General Pam Bondi said in a statement that the Justice Department “has no higher mission than keeping the American people safe and protecting our nation from hostile foreign actors who would do us harm.”

“Thanks to the hard work of our excellent DOJ attorneys, this defendant — who clandestinely attempted to bring a destructive substance into the United States — will face years behind bars,” the attorney general says.

“I can confirm that the FBI arrested a Chinese national within the United States who allegedly smuggled a dangerous biological pathogen into the country,” FBI Director Kash Patel said on Tuesday.

(FBI)

FBI Director Kash Patel addressed the arrest of Jian late Tuesday on X, formerly Twitter.

“This case is a sobering reminder that the CCP (Chinese Communist Party) is working around the clock to deploy operatives and researchers to infiltrate American institutions and target our food supply, which would have grave consequences … putting American lives and our economy at serious risk.”

U.S. Custom and Border Protection, Director of Field Operations Marty C. Raybon says the criminal charges against Jian and Liu are indicative of CBP’s critical role in protecting the American people from biological threats that could devastate its agricultural economy and cause harm to humans.

“This was a complex investigation involving CBP offices from across the country, alongside our federal partners,” says Raybon in a prepared statement. “I’m grateful for their tireless efforts, ensuring our borders remain secure from all types of threats while safeguarding America’s national security interests.”

U.S. Cattle Industry Urges Mexico's Border to Remain Closed Over Spread of New World Screwworm

Tue, 13 May 2025 21:31:47 GMT

New World screwworm (NWS) has been detected in Mexico only 700 miles from the U.S. border. With the impending threat, National Cattlemen’s Beef Association (NCBA) says it’s not a matter of if the U.S. gets the deadly pest — but when.

Mexican officials said Tuesday they won’t close the southern border to cattle from Central America, but the U.S. cattle industry strong supports USDA’s decision over the weekend to suspend cattle, horse and bison imports from Mexico , saying the 15-day suspension will likely be extended due to Mexico’s lack of action so far.

NWS Detected 700 Miles From the U.S.
It’s an issue that started in November. The detection of NWS in Chiapas, which is near the Guatemala border, caused USDA to close the border to cattle imports. While shipments resumed in February, USDA says Mexico isn’t doing enough to eradicate the invasive pest, causing an even greater threat to the U.S. cattle industry. And now NCBA wants the U.S. to ramp up efforts as well.

“When we discovered New World screwworm flies in the southern border of Mexico right before Thanksgiving back in November, at that point in time, USDA provided counsel, they provided some money to help the Mexican government try to stop the incursion of the fly,” Colin Woodall, CEO of NCBA, told AgriTalk’s Chip Flory.

“But unfortunately, because of the ineptitude of the Mexican government, quite frankly, the corruption of the Mexican government, the inability to actually allow the planes that are carrying the sterile males to land and to be able to do their job, they have now come further north,” Woodall says. “And right now we know that New World screwworm flies have been detected just 700 miles south of the U.S. Border.”

Woodall told AgriTalk’s Flory that the pest is now way too close for comfort.

Mexico Won’t Close Mexico/Central America Border
According to Reuters, Mexico’s agriculture minister said on Tuesday it will take a long time to eradicate the pest. While the officials said they won’t close Mexico’s southern border to cattle from Central America, Mexico will tighten the flow of cattle from the south of the country to limit the potential spread of the screwworm.

“We are going to be restricting cattle movement from the south of the country much more tightly,” Mexican Agriculture Minister Julio Berdegue said on Tuesday, adding that “closing the border is a complex issue that needs to be carefully analyzed, because it also impacts the national meat supply.”

MEXICO AGRICULTURE MINISTER:

WILL TAKE A LONG TIME TO ERADICATE SCREWWORM FROM MEXICO AND CENTRAL AMERICA
— PiQ (@PiQSuite) May 13, 2025

Derrell Peel, Oklahoma State University Extension Livestock Marketing Specialist, spoke with Drovers about the geography of southern Mexico and how the NWS has been able to move further north.

“Mexico has that narrow point down there at the bottom, the Isthmus of Tehuantepec, then to the east of it is the Yucatan Peninsula. To the west is the rest of Mexico, and that narrow gap is, historically, where we established the boundary way back when,” Peel explains. “When we initially controlled screw worm in the U.S., we pushed it down through Mexico and got it past below that isthmus, and that was the boundary for years. Then we eventually got it down to Panama, but it got away from them. In Panama, it came back up through Central America, and now that’s the reason we closed the border. It’s actually jumped past that isthmus and is into a part of Mexico now where it’s going to be increasingly difficult to contain it, just physically. That’s the concern and the reason for this latest action.”

NCBA Blames Corruption in Mexico’s Government
Woodall told AgriTalk the country has poorly managed the situation so far and was pointed with his words, saying it’s because of the Mexican government’s failures that Rollins stepped up and closed the border on Sunday to “send a very clear signal that they have failed, and they’ve got to step up their approach.”

“We do know that the first meeting to review the ban is in about 15 days, and then it’ll be reviewed on a month-by-month basis,” Woodall said on AgriTalk. “That’s what the secretary has said. But unless they do something miraculous as far as changing the approach that they are taking in trying to address this in Mexico, I doubt that it’ll be lifted in 15 days just because of what we’ve already seen. They’ve had six months to step up here and try to address it, and they’ve fumbled the ball.”

“They’ve had six months to step up here and try to address it, and they’ve fumbled the ball.”

Colin Woodall, Chief Executive Officer, NCBA

The corruption claims are rooted in what the U.S. has experienced over the past several months. As the U.S. has tried to ramp up efforts to help stop the spread, Woodall told Flory that there have been instances where the government wouldn’t allow U.S. planes to fly over impacted areas, or not allow those planes to land.

“Will they allow that without additional hurdles or trying to extort money from these planes?” Woodall says. “Will they be true cooperators in helping us get those sterile flies delivered into the country? And can we show that there is a check in their northern approach? If we can look at some things like that, then we’ll be willing to go back to the table, because as I said, we know that this is an economic impact on us, but it’s also a pest that we do not want here domestically.”

The Risks of NWS If It Enters the U.S.
The risks are high. Not only is the U.S. beef cattle herd the smallest in more than 60 years, NWS can be lethal to other species.

“We have to be prepared, and that’s why I talked about it. We need to make sure producers understand what to look for because if you don’t catch it fast, you’re going to lose that animal,” Woodall says. “Also this is not just a cattle issue; we’re talking all warm-blooded animals. This can be on birds. This can be on hogs. It can be in pets like dogs. And it can be in people. So, this is going to be a significant issue that we have to deal with not just as a cattle industry, but us in agriculture because I think it also could look really bad from an optics standpoint if somebody’s dog gets screwworms and they want to blame us as agriculture for being responsible for it.”

“This is not just a cattle issue; we’re talking all warm-blooded animals. This can be on birds. This can be on hogs. It can be in pets like dogs. And it can be in people.”

Colin Woodall, CEO of NCBA

Woodall says NWS is a nasty parasite. It hasn’t been in the U.S. since the 1960s, but the reason it’s so difficult to manage is it lays larva, and the larva dig into the flesh of the animal, basically eating the flesh.

“That’s how it develops,” Woodall says. “And so, if it’s not treated, within four to seven days, you can lose an animal. This is a significant animal health issue.”

Currently, there’s a sterile fly production facility in Panama. Jointly funded by the U.S. government, the facility produces a little more than 100 million sterile flies a week, according to Woodall.

“Now, when we were dealing with this down in southern Mexico, 100 million were enough to be able to stop it,” he says. “But now that they have gone through that phytosanitary border and are coming north, that’s no longer going to be enough. We do not have enough sterile flies.”

NCBA Is Working with Congress and USDA to Ramp Up Sterile Fly Production Domestically
NCBA is talking to both USDA and Congress about building a sterile fly production facility in the U.S. When NWS was a problem in the U.S. more than 60 years ago, there was a production facility based in Texas.

There is legislation to do just that. The STOP Screwworms Act was introduced by Rep. Tony Gonzales (R-TX) and Sen. John Cornyn (R-TX). It would fund the opening of a new sterile fly facility in the United States, with the legislators saying the bill would help protect both livestock and human health from the New World screwworm.

“One of the things that we’re also talking to the secretary about and also with Congress is how do we have the funding to build a sterile fly production facility here in the United States because that is the only way we’re going to stop these flies, get them out of the United States, out of Mexico, and ultimately push back into South America,” he says.

“One of the things that we’re also talking to the secretary about and also with Congress is do we have the funding to build a sterile fly production facility here in the United States?”

Colin Woodall, CEO, NCBA

He says in the ‘60s, it took more than 400 million sterile flies a week to eradicate the issue.

“We are focused on getting the domestic production up and running as quickly as possible, so is Secretary Rollins,” Woodall says. “She’s doing a tremendous job in leading this effort. This is something that she has taken on personally. And so I have a lot of faith in her and her willingness to help us as an industry push back this pest, eradicate it as quickly as possible and try to get back to normal training.”

Groups like the Texas & Southwestern Cattle Raisers Association (TSCRA) also support a bill to protect the U.S. from NWS.

“The STOP Screwworms Act is a vital step in protecting the U.S. cattle herd from the growing threat of the New World screwworm. This legislation provides USDA the support needed to construct or retrofit domestic sterile fly production infrastructure which Texas Southwestern Cattle Raisers Association believes is essential in preventing a widespread outbreak,” President Carl Ray Polk Jr. said in a statement. “We are grateful to both Sen. Cornyn and Rep. Gonzales who understand the importance of acting quickly to support cattle raisers and ensuring the threat of the New World screwworm is taken seriously at the highest levels in Washington.”

How Will Germany's Foot-and-Mouth Disease Outbreak Impact Global Pork Trade?

Tue, 21 Jan 2025 14:17:58 GMT

Despite a 25% decline in production over the past decade, Germany remains a global leader in pork exports, particularly to the rest of the European Union.

Foot-and-mouth disease was recently detected in a water buffalo herd at a small exotic farm near Berlin. Germany immediately worked to isolate the impacted animals and trace the origin. But because of the FMD detection, most livestock products cannot be exported outside of the EU.

Restrictions on German pork because of this FMD outbreak could leave a void in some markets, but lack of market access and available products could limit the opportunities for U.S. pork, experts say.

Three of the main export markets for German pork present challenges for any market share gains for U.S. pork. The United Kingdom and Vietnam have significant tariffs on U.S. pork as well as sanitary and phytosanitary (SPS) barriers. And while the U.S. does significant pork trade with South Korea, most Korean imports of German pork are bellies, which are always in strong demand domestically in the U.S.

“U.S. exports to UK are minimal,” Erin Borror, U.S. Meat Export Federation’s (USMEF) vice president of economic analysis, said in the USMEF Audio Report. “This is an area where we’ve been saying, there should be great opportunity if we could have some type of reciprocal market access. But today, the combination of tariffs and quotas, and then on top of that, the SPS issues, our exports to UK are limited, highly limited.”

She adds that U.S. share into Vietnam is also minimal, partially because of the tariff disadvantage. Korea is mostly single rib bellies — product that the U.S. exports, but really just small volume, Borror explains.

“The U.S. consumer loves bacon, so that belly price is generally, on average, higher than the European belly price,” she says.

Emergency USDA Funding Available to Protect U.S. Livestock and Animals from New World Screwworm

Fri, 13 Dec 2024 18:09:22 GMT

On Dec. 13, the United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) announced $165 million in emergency funding from the Commodity Credit Corporation to protect U.S. livestock and other animals from New World screwworm (NWS) and to increase USDA’s ongoing efforts to control the spread of NWS in Mexico and Central America. NWS are fly larvae that infest living tissue of warm-blooded animals, causing infection, according to an agency release.

NWS has spreadout throughout Panama and into Costa Rica, Nicaragua, Honduras, and Guatemala during the last two years. With the finding of a NWS-positive cow found in Mexico on Nov. 22, APHIS and Mexican authorities have taken additional measures to prevent further spread through surveillance, animal health checkpoints and domestic preparedness. In addition, USDA is working with partners in Mexico and Central America to establish a barrier on the Isthmus of Tehuantepec, eradicate NWS from the affected areas, and reestablish the biological barrier in Panama.

“The current outbreaks in Central America demonstrate the need for USDA to increase its investment in NWS eradication and prevention,” says Jenny Lester Moffitt, USDA Under Secretary for Marketing and Regulatory Programs. “If NWS were to spread to the United States, it would result in significant economic losses and threats to animal health and welfare. This funding will allow for a coordinated emergency response to control the outbreak and prevent NWS from spreading to the United States.”

APHIS asks all producers along the southern border to watch their livestock and pets for signs of NWS and immediately report potential cases to their local veterinarian, State Veterinarian’s Office, or APHIS Veterinary Services.

According to APHIS, eradicating NWS is only possible through sterile insect technique. With this method, sterile flies are released into an area where a known population has become established. The sterile male screwworm fly mates with fertile female screwworm fly, causing the population of screwworm flies to decrease until it eventually dies out.

Drought Increases Aflatoxin Risk

Wed, 11 Nov 2020 05:08:44 GMT

Hot and dry cornfield conditions are breeding grounds for dangerous aspergillus ear and kernel mold that produces aflatoxins. This toxin is a known carcinogen, can harm livestock if fed and can lead to rejection at the elevator if abundant in a load.

Drought states are at a particularly high risk for the disease this year.

Aspergillus ear and kernel mold is a green to yellowish green, powdery fungus that survives on plant residue. In addition, spores can be transferred by wind. Damaged and exposed kernels are more susceptible to Aspergillus.

There are ways to manage aflatoxins, according to AgriGold Agronomist Brandon Nystrom.

Scout to determine if the mold is present
Change combine settings and grain moving equipment to minimize kernel damage and remove cracks, fines and lightweight, diseased kernels
Consider harvesting when the corn is above 20% moisture as less Aspergillus will be present and if you do, dry rapidly to at least 14% moisture in under 48 hours
Don’t store grain in any non-aerated site for more than six hours
Manage storage conditions to discourage fungi growth, cool dried grain to 35 to 40 degrees Fahrenheit

If you find mold that produces aflatoxins in fields it will limit where you can sell the grain. The table below, from Iowa State University (ISU) Extension showcases outlets for the infected grain.

Note, blending aflatoxin-contaminated corn is not legal except for on-farm use, according to Alison Robertson, professor of plant pathology and microbiology at ISU. Ethanol could be another outlet for infected grain. For on-farm use, anhydrous ammonia can reduce the contamination .
