3 Factors Fueling Americans' Obsession with Protein

Fri, 06 Jun 2025 15:48:09 GMT

Meat is having a moment, and the craze for more protein is benefiting protein across the board. The fact cattle prices continue to crush records is proof of that, as well as the robust demand for pork.

“I am still bullish of dairy. I’m bullish of beef. I’m bullish of pork and poultry,” says Dan Basse, AgResource Company . “I think as you think forward, I see the next two or three years as being the years of protein. It’s that side of the fence in agriculture that’s going to do very well.”

Basse’s optimistic outlook on protein hinges on one major factor: consumers’ ability to pay for it.

“I’m still bullish of protein, until we see the labor force start to shrink in the United States, and I start to see disposable income coming down. Again, there’s not a period looking backward in history that I can find where disposable income on a personal basis has risen this quickly from 2020 to 2025,” he says.

“Meat protein, not just pork or not just beef, but meat is having a moment. I’m an economist, so I have concerns on the macroeconomic front, but it is exciting to be in an era where the public’s desire for meat protein is growing,” says Glynn Tonsor, a professor in the Department of Agricultural Economics at Kansas State University.

People Are Eating More Protein Than Ever Before

Cargill’s 2025 Protein Profile found people are eating more protein than ever before. The report found 61% of consumers report increasing their protein intake in 2024, which is up from 48% from 2019.

According to Cargill, the shift in shoppers’ preferences toward whole, minimally processed foods, is giving protein a chance to shine.

“It’s really important to remember the U.S. public wants meat protein,” Tonsor says. “There are a lot of signs. We are in a pro protein environment. I don’t think there’s issues. I actually think there is a celebration about the taste and the eating experience and so forth for all the major proteins.”

A Slight Shift in May’s Monthly Meat Demand Monitor

Tonsor also authors what’s called the Monthly Meat Demand Monitor (MDM) , which tracks U.S. consumer preferences, views and demand for meat. The first half of the year, the MDM continued to show consumers’ growing demand for protein, but in the report in May, it did show a slight shift.

“The biggest takeaway from the MDM would be we have two conflicting patterns,” says Tonsor. “One is the public really wants meat protein, but the macroeconomic environment is giving us some pause. So, we continue to see strong signals people want protein. Taste is leading that decision, so that’s good and very supportive, but we also see lots of uncertainty on the macro-economic front. So, trade discussions, elevated unemployment, inflation concerns and so forth. Those are not supportive of meat demand, so those are the two trends that are fighting the way out.”

Tonsor points out the May MDM showed a pullback in consumers eating away from home, like in restaurants, but showed a boost in retail demand, which would be grocery stores.

“But part of that is a substitution away from restaurants,” he says. “And that’s across the board. It’s not just pork or beef or chicken. It’s all of them that we track, so I do think it is a headwind that is growing here in 2025.”

Tonsor says if confidence in the economy rebounds, and tariff discussions ease, the restaurant piece of meat demand could quickly recover, especially considering we’re entering the summer months, where meat demand is typically higher.

3 Major Drivers Behind the Protein Craze

And even with the pause in restaurant demand in May, Tonsor says the push for consumers to eat even more protein doesn’t seem to be going away, and it’s being driven by three major factors.

“More people are having meat as an ingredient rather than center of the plate. So, it’s coming across as more convenient. It’s an input,” Tonsor says. “Also younger folks in particular are quite physically active, and their demand for protein and that broader lifestyle is elevated.”

Those two factors are strong drivers of meat demand, especially in the younger crowd. But another supportive piece of the growing demand for protein is related to weight loss drugs.

“We have a GLP-1 effect, so Ozempic, Mounjar and so forth, in the MDM, we put out a report earlier this year, showing maybe 15% of the U.S. public is using the GLP-1,” Tonsor says. “That’s a higher end, but that’s what we estimate. And if you are on those products, you’re actually consuming beef, pork and chicken more frequently.”

He says all of those things add up to support the growth in meat demand.

“It’s the income and the future status of my finances is mainly the only headwind at the moment, and that’s why I keep reiterating that concern,” Tonsor says.

Demand is What’s Pushing Cattle Prices to New Highs

It’s not just the hog industry that’s benefiting from the strong demand, both domestically and with exports

Cattle prices continue to crush records. But according to one veteran cattle analyst, it’s not historically tight cattle numbers pushing prices higher, it’s the strong demand.

“This price increase that we’re experiencing in the industry is demand-driven,” says Randy Blach, CEO of CattleFax. “Our per capita supplies were flat last year. They’re going to be flat again this year. And yet we’ve had a market that’s gone from a $1.75 to $2.25. That’s all been demand driven with what we’ve seen throughout the industry.”

The incredible demand is pushing beef demand to its highest level in nearly 40 years.

“Beef demands that are a 37-year high,” he says. “And I think when people think about demand, obviously quality has been the key to that. We’ve seen the quality of the animals being produced has increased substantially.”

As record-high cattle prices also push the cost of beef higher, that would push consumers to eat more pork and chicken in the past. But it’s a trend Tonsor is not largely seeing this time around.

“We see some of that, but not nearly as much as you might think. So, there’s less of that adjustment than historically we would have seen,” Tonsor says. “This is 100% Glynn’s opinion, but I think habits are a little stickier. Persistence of an item in your meal is a little sticker than in the past. Meat is an ingredient, not just the center of the plate. Higher beef prices have not elevated chicken demand as people have expected, and I think it’s because the consumer substitution effects, they exist, but they’re not as strong as they were 20 years ago.”

As consumers crave more protein, it’s a bright spot for all of livestock with many hopeful this isn’t just a trend but a permanent fixture on consumers’ plates.

What Do Foot-and-Mouth Disease Outbreaks in Europe Mean for the U.S.?

Fri, 28 Mar 2025 22:09:30 GMT

Foot-and-mouth disease (FMD) is rearing its ugly head in Europe. After an outbreak in water buffalo in Germany in January, an outbreak in cattle in Hungary in early March and an outbreak in cattle in Slovakia last week, why now? What is the U.S. doing to keep this foreign animal disease out and protect the country’s livestock industry?

“FMD is caused by a virus that affects cloven-hoofed animals so that can include cattle, pigs, sheep and goats,” explains Megan Niederwerder, DVM, who serves as the executive director of the Swine Health Information Center (SHIC). “It does not affect humans and is not a threat to food safety, but it has significant trade implications once it is introduced into a country.”

FMD has been fairly quiet in these European countries – with no cases reported for decades. Other parts of Europe have seen outbreaks more recently like the 2001 outbreak in the United Kingdom that caused a crisis in British agriculture and tourism and resulted in the cancellation of the World Pork Expo held in Des Moines, Iowa.

“FMD really decimated the United Kingdom,” says Barb Determan who was serving as president of the National Pork Producers Council (NPPC) at the time. “It became very apparent that we couldn’t guarantee the safety for our U.S. pig herd because of the high numbers of international travelers that would be at the show. We had to cancel World Pork Expo out of an abundance of precaution.”

Although there is still a lot to be discovered about how FMD was introduced into these populations, it’s a significant warning to the U.S. to be on alert.

That was the first time, but not the only time World Pork Expo was canceled. The event was also canceled in 2019 because of the African swine fever outbreak in China and again in 2020 due to the COVID-19 pandemic.

“That was a hard financial decision,” Determan says. “We had just completed the separation agreement between NPPC and the National Pork Board. NPPC was very tightly budgeted at that time, so it was a huge hit.”

However, keeping the U.S. pig herd safe was the most important thing on everyone’s mind. She says they made their decision after hearing reports from veterinarians who had been to England to better understand the extensiveness as well as from the USDA that had sent veterinarians over to help.

“At that time, we didn’t have near the biosecurity practices and things that we do now with the disinfectant foot mats,” Determan says. “We also don’t have live pigs on the on the grounds now compared to how we did things many years ago. We used to have live pigs everywhere on the fairgrounds in the early 2000s from genetics companies with pigs in their displays to the pigs in the live shows.”

The Truth About FMD
The clinical signs of FMD are similar to what the name implies. It can cause vesicles or blisters on the feet, mouth and tongue of animals that are infected. The U.S. has not had a case of FMD since 1929.

“We certainly want to keep it that way, as the economic implications for producers are significant if the virus is introduced,” Niederwerder says.

Compared to many viruses, FMD is a highly stable, non-enveloped virus that allows it to be infectious for longer periods. It’s very contagious and highly transmissible. Not only are there risks with transmission of the virus through infected meat products that may come in through illegal trade, but it can also be carried on contaminated clothes or equipment or supplies of humans.

“The human would not be infected, but certainly people can carry the virus on contaminated clothing,” Niederwerder says. “That’s why it’s really important as we think about prevention of entry into the U.S.”

FMD causes fever and pain. It results in excessive salivation and causes reduced milk production in dairy cattle.

“When you think about the impact, certainly there’s an impact on animal health with regards to the clinical signs, but even further is this impact on trade restrictions and the economic losses for producers,” Niederwerder says. “When you try and contain the virus, that oftentimes results in those infected animals being culled or euthanized so the disease no longer has the chance to spread.”

Why Should the U.S. Pay Attention?
When a virus moves into a new geographical range or is reintroduced into a country that has maintained a negative status for a long period, Niederwerder says it’s critical to reassess the risk to the U.S.

“In January, Germany reported their first case in over 30 years in water buffalo near Berlin,” she explains. “It was 14 animals, and those animals were all culled after the infection was confirmed but certainly trade restrictions and implications on surrounding areas of that Berlin farm were significant.”

Fast forward to March when two additional countries have reported cases. Hungary reported FMD in a single farm of cattle in the north part of the country for the first time in over 50 years. Shortly thereafter, the virus appeared in Slovakia (who also hadn’t seen a case in over 50 years) in multiple herds of cattle.

“Just recently, another herd was a suspect herd in Slovakia, near the southern border near Hungary,” Niederwerder says. “This is certainly concerning about how this virus is being reintroduced. Is it associated with contaminated fomites that may be in the country or traveling to new locations? Is it associated with wild boar? Could it be associated with infected hay?”

Although there is still a lot to be discovered about how FMD was introduced into these populations, it’s a significant warning to the U.S. to be on alert .

“We need to do everything we can to make sure it doesn’t get reintroduced into the U.S.,” Niederwerder says. “How can we amp up any biosecurity measures that are necessary to reduce our risk? We also need to think about reducing the risk of introduction into our country through travel and illegal trade.”

Be on Alert
Livestock operations should reevaluate biosecurity protocols. If any of your farm’s employees travel to areas where there are infected animals, implement a quarantine period for entry back into your U.S. farm, she advises.

“Be vigilant,” Niederwerder urges. “One of the challenges of FMD is that it does cause these characteristic lesions of vesicles or blisters on the mouth, nose or the hoof. What becomes very tricky is that those clinical signs are indistinguishable from other vesicular diseases such as Senecavirus A. If producers and veterinarians see these lesions, they must report it immediately so it can be investigated and confirmed that it is not FMD virus.”

FMD is not just a disease of pigs and cattle, she points out. Sheep, goats and cloven-hoofed zoo animals may also be impacted by FMD. This increases the breadth of what the industry needs to monitor.

“The world is very small now,” Niederwerder says. “Not only do people travel more internationally, but animals move around more than ever, too. It’s extremely important for those of us that are producers to keep our eyes open and pay attention to what’s going on worldwide so we can be as prepared as possible for any change in disease risk.”

That’s one of the ways that SHIC is trying to help producers. SHIC provides timely domestic and global disease updates to producers.

“Watching the SHIC global disease report is really important for producers,” Determan says. “It comes out every month and really gives you a feel for what’s happening in the entire world from a swine health standpoint. The biggest lesson we learned from the 2001 FMD outbreak is that looking farther out than just our own farm gate is so important.”

Economists Fear the U.S. Will See a Recession in 2025, And That Could Eat Into Consumers' Demand for Meat

Fri, 28 Mar 2025 17:56:24 GMT

Consumer meat sales hit record-breaking levels last year. The craze for protein-filled diets has been a storyline that’s helped drive meat demand, which is good news for meat producers. Ag economists warn, however, the major limiting factor for meat demand, and meat prices, in 2025 just may be what happens in the overall economy.

The March Ag Economists’ Monthly Monitor asked economists if they think the U.S. general economy will see a recession in 2025, and 62% said yes.

Recent reports agree with that sentiment, as the Federal Reserve’s key inflation index rose more than expected in February and consumer spending posted a smaller-than-projected increase, according to the Commerce Department. Both could be warning signs of what’s ahead.

As a follow up question, The Ag Economists’ Monthly Monitor survey asked, “In what ways does the U.S. economy impact meat demand in 2025?” Respondents had no shortage of opinions on that.

Here’s a rundown of some of their reactions:

“If real wages fall, there will be a substitution toward other protein/cheaper meat cuts.”
“Slower growth (even if the U.S. does not endure a recession) will reduce consumer willingness to spend, especially at a time when beef prices, in particular, are high.”
“A downturn in economic growth impacts disposable income and should slow animal protein demand.”
“There is a positive correlation between GDP and meat demand, particularly between GDP and higher end cuts.”
“When the U.S. economy is strong and incomes increase, consumers have more disposable income to spend on meat and higher quality cuts of meat. When the U.S. economy is weak and disposable income tightens, consumers may reduce meat in their diet or turn to less expensive meat options.”

Not all economists expect U.S. consumer demand to fall off though, even if the U.S. officially enters into a recession.

“Labor income is growing faster than inflation. Most U.S. firms are profitable - at least as of current earnings reports,” said one economist.

Another shared, “I do think consumer demand will be lower in 2025 than it was in 2024. That being said - 2024 consumer expenditures and demand were a lot higher than I anticipated at the beginning of the year. Two indicators that are showing up, and are unsustainable right now, are reducing savings accounts and increasing credit card debt. I think it leads to slower meat demand in 2025, partially due to lower meat availability and partially due to slowing consumer demand. Notice I said ‘slowing’ consumer demand and not ‘declining/negative’. Demand does not have to decline year-over-year to impact meat prices. Slowing can do the same thing.”

The GLP-1 Effect
What could have an even bigger impact on meat demand, and even more so than inflation and a recession, is the use of GLP-1 drugs for weight loss. GLP-1 drugs not only moderate users’ blood sugar levels, but also affect their appetites by suppressing hunger cravings.

“U.S. consumer preference for meat demand is strong, though I would be paying attention to the growing use of GLP-1s as it relates to all agricultural product demand,” one economist responded.

The good news is studies have shown those who use GLP-1 drugs often crave healthier items and often consume more protein versus unhealthy foods.

Starting From a Place of Strength
Forecasting meat demand in 2025 relies on a number of factors. But a positive trend is how consumers, especially the millennial generation, are buying more meat. As PorkBusiness.com reported this week, consumers are buying more meat than ever. In 2024, meat sales hit a record high of $104.6 billion and total pounds sold increased by 2.3%, which was cited in the latest Power of Meat.

More people want meat today, but economists are concerned any economic pain could eat into overall meat demand.

Take the Stress Out of Social Media: Navigate Detractors

Thu, 20 Feb 2025 14:00:00 GMT

Have you ever wanted to post on social media but were worried about potential backlash? You want to share your farm, but are worried about receiving potentially negative comments about sow housing? Maybe you are worried about getting tough questions about the use of hormones or antibiotics when it comes to feeding your animals or treating them for illnesses?

Unfortunately, this scenario is all too common for farmers, veterinarians and others in the ag community advocating for animal agriculture on social media. Negative comments have the potential to steer the conversation down an unproductive path. However, if you know how to handle contentious issues online then you can help people understand the animal agriculture community’s commitment to animal care, responsible antibiotic use, sustainability and other core values.

Before deciding how (and if) to respond to comments, take a deep breath and ask yourself a few key questions:

1. Is the comment relevant or is it completely off-topic?

2. Who has made the comments? Are they genuinely curious or are they a known extreme animal rights activist?

3. Consider, “Is it possible they have a different perspective?” or “Is there something that could have shaped this person’s opinion?”

4. Will responding to the comment help other people who will read your response?

If the person has left a completely irrelevant comment, don’t feel obligated to respond. If the comment included offensive remarks, feel confident in hiding the comment or blocking the person from commenting again. Remember, your social media page is your space, and you can set community guidelines.

Depending on who has left the comment can determine how you respond. By clicking on the commentor’s profile you can quickly learn if their comments come from a place of true concern and interest, like a parent concerned about feeding his or her children safe, nutrient-dense foods, or potentially an animal rights extremist with no intention of having a productive conversation about animal agriculture.

If you have concluded that the commenter is likely not open to having a dialogue, still ask yourself if responding to the comment will help others understand your perspective. Social media is a very public space and there are many more people reading your posts and comment sections than actually engaging.

Once you have asked yourself these questions and have decided that responding is your next step, look for common ground on a related topic – such as food safety and family values. Before jumping into the safety and animal welfare benefits of using antibiotics, validate their concerns and offer empathy. Then, ask permission to share your personal experience with using antibiotics on the farm. If the conversation is going well, follow up with the science and offer resources or other people to follow on social media if they are interested in learning more.

Most importantly, know that you can always ask for help. Bring in your friends who also have experience responding to contentious issues, reach out to your local partners, or the Animal Agriculture Alliance to help you moderate difficult conversations.

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.

The full conversation between Naig and Flory on AgriTalk is available below.

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.

New Study Says Domestic Cats Need To Be Evaluated More For HPAI H5N1 Implications

Mon, 13 Jan 2025 21:07:11 GMT

Dairy cattle have garnered most of the agriculture industry’s attention in the past year, with regard to outbreaks of the highly pathogenic avian influenza A (HPAI) H5N1.

Now, some researchers are turning their attention to other animals on the farm impacted by the virus: cats.

A new study published Monday in the journal Emerging Microbes & Infection addresses how domestic cats are affected by the virus and notes concerns such felines could offer the potential for HPAI H5N1 to evolve into a more dangerous version of the virus.

The study – which addresses the deaths of 10 cats in rural South Dakota last April – is not the first time researchers have raised concerns about the virus in cats and the potential for transmission to other mammals.

‘Urgent Need For Surveillance’
Researchers at the University of Maryland School of Public Health said in June 2024 that a “20-year review of bird flu in felines suggests urgent need for domestic cat surveillance.”

Kristen Coleman, an assistant professor in the UMD School of Public Health, and an affiliate professor in the University of Maryland Department of Veterinary Medicine, said, “As companion animals, domestic cats provide a potential pathway for avian influenza viruses to spillover into humans.” (Researcher Warns Pet Cats Risk Getting Bird Flu)

“We looked at the global distribution and spread of bird flu infections in feline species between 2004 and 2024 and found a drastic rise in reports of feline infections starting in 2023, with a spike in infections reported among domestic cats, as opposed to wild or zoo-kept animals,” added Coleman, who was not involved in the South Dakota study.

There is no study that shows transmission occurs from HPAI H5N1-infected cats to humans. Furthermore, current research shows HPAI H5N1 does not readily spread among humans, though studies have noted one or two key mutations could change that fact.

The virus often does take a deadly toll on felines. According to the University of Maryland’s School of Public Health , infected domestic cats have a mortality rate of up to 67%.

Last week, the Cornell University College of Veterinary Medicine Animal Health Diagnostic Center published directions online for veterinarians testing cats for highly pathogenic avian influenza (HPAI) .

AVMA Weighs In
“Dozens of cats are known to have contracted the virus, including barn and feral cats, indoor cats, and big cats in zoos and in the wild (e.g., mountain lions, tigers, leopards, and bobcats),” according to the American Veterinary Medical Association (AVMA). “Cats were already known to be susceptible to the H5N1 virus, with several feline cases linked to poultry or wild bird exposure before the cattle outbreak began,” AVMA said.

See Avian influenza A (H5N1) in cats for the Association’s recommended practices for dealing with any suspected of being infected by the virus.

‘A Possible Link’ To Local Cattle
The study published on Monday said virus-infected birds could have played a role in the South Dakota felines’ demise.

In addition, the report said: “The exact source of infection remains unclear; however, phylogenetic analysis of H5N1 sequences from two of the cats reveals a close genetic relationship to clade 2.3.4.4b strains previously detected in local cattle, suggesting a possible link.

“Additionally, the presence of bird feathers near the deceased cats indicates the likelihood that infection may have occurred through the consumption of virus-infected birds. However, because the disease typically requires several days to manifest post-ingestion, the exact timing of exposure is unclear. This evidence points toward a plausible cattle-to-bird-to-cat transmission pathway, supported by recent studies that identified H5N1 sequences across multiple species on affected farms, including dairy cows, wild birds, domestic cats, and raccoons.”

Many Mammal Species Impacted
According to USDA-APHIS, more than 200 mammal species in the U.S. have been infected by the virus since 2022.

Along with cows and cats, other U.S. mammals infected with the virus include a bottlenose dolphin, foxes, bobcats, mountain lions, coyotes, skunks, harbor and grey seals, opossums, squirrels, minks, otters, black bears, brown bears, polar bears, and a single pig on a backyard farm in Oregon, confirmed in late October.

The CDC encourages veterinarians and other individuals working with cats or other mammals that are suspected or confirmed positive for HPAI H5N1 to take precautions to prevent potential unprotected exposures.

As we leave 2024 behind and start the New Year, the U.S. needs to step up its efforts to stop the spread of HPAI H5N1 — for all our sakes.

Based on the official numbers of virus cases reported in the dairy industry and beyond, in poultry and wildlife, it doesn’t appear we are moving fast enough individually or collectively to rein in this virus.

I’m trying to tread lightly on this topic, but candidly, I’m afraid.

The Impact On People

I’m very concerned about what this virus has the potential to do to human beings — our dairy farmers, farm workers, veterinarians — and, yes, the rest of us.

While the Centers for Disease Control and Prevention (CDC) says the “current risk to individual and population health remains low in the U.S.,” that statement is less reassuring to me as time marches on and the virus spreads.

As of Dec. 30, 2024, the CDC has confirmed “only” 66 cases of the virus in people. See H5 Bird Flu: Current Situation.

That number is likely very low, based on what veterinarians have told me since March 25, 2024, when the virus was first confirmed in dairy cattle.

More importantly, consider what scientists are saying.

The American Veterinary Medical Association (AVMA) reported on Dec. 30 that “the virus strain found in dairy cows in the U.S. may only need one mutation for it to be able to spread among humans, according to a study published in the journal Science in early December.”

Dr. Les Sims, a veterinary consultant who has worked internationally for over 30 years on the prevention and control of major infectious diseases of food-producing animals, warns in the article: “The longer this virus circulates unchecked, the higher the likelihood it will acquire the mutations needed to cause a pandemic. We need to act urgently to prevent this scenario.”

The AVMA’s complete article is available here:
Novel bird flu strain continues to threaten animal, public health

Virologists Share Their Perspectives
Another insightful article is The state of H5N1 infections and research as 2025 approaches, posted on Dec. 24 by Chemical & Engineering News. It notes:

“As more cows get infected with H5N1 bird flu, and more people get exposed to infected animals, there’s increased opportunity for the virus to evolve into a version that’s more capable of spreading between people,” says Ed Hutchinson, a virologist at the University of Glasgow. “The process could result in the virus accumulating mutations that allow for better replication and transmission, including between people.”

“Virologists are also concerned about a situation where a person simultaneously gets infected with H5N1 and human influenza virus H3N2 or H1N1, each of which is currently circulating as flu activity gains pace . But it’s hard to predict whether genetic reassortment between those viruses would create a version of H5N1 that’s more adept at spreading in humans,” says Richard Webby, an influenza virologist at St. Jude Children’s Research Hospital, in the Chemical & Engineering News article.

Consider what one physician told NBC News Science Reporter Evan Bush on Dec. 23:

“The traffic light is changing from green to amber,” said Dr. Peter Chin-Hong, a professor of medicine at the University of California, San Francisco, who studies infectious diseases. “So many signs are going in the wrong direction.”

Impacts In Dairy, Poultry, Wildlife
The virus continues to spread in the dairy industry, and it’s alarming the toll it’s already taken in domestic poultry and wildlife. In summary:

In Dairy: On March 25, 2024, the USDA, CDC and FDA made their official confirmation of the virus in dairy herds in two states, Texas and Kansas. A short nine months later, on Dec. 30, 2024, we officially had 913 herds affected in 16 states, according to the CDC. See Domestic Summary.

In Poultry: the USDA says HPAI H5N1 outbreaks in poultry have been detected in all 50 states —1,324 commercial flocks and 729 backyard flocks—resulting in the depopulation of more than 125 million turkeys and chickens. See the Full Report .

In Wildlife: The virus has affected more than 200 wildlife species across the U.S. See Detections of Highly Pathogenic Avian Influenza in Mammals.

Do What You Can
I don’t want to experience “another Covid” or a virus that could be even worse. I’m sure no one else does, either.

We must act individually and collectively to stem the spread of HPAI H5N1.

Please don’t “kick the can” on down the road and expect someone else to do your part. Take the steps you can to help, however small they might be.
That’s what I’m trying to do, too.

2025 Weather: Drought and Root Zone Maps Signal Dryness Ahead

Mon, 30 Dec 2024 19:25:59 GMT

As 2024 comes to an end, roughly 70% of the nation is experiencing some level of drought and dryness.

Recent precipitation led to small improvements in parts of Oklahoma and Arkansas northeast to the Central Appalachians. Since its peak in September, the drought affecting the Central Appalachians and Upper Ohio Valley has steadily improved.

In the northeast, near to above-normal precipitation in the past 30 days means drought conditions have improved.

Across the Southeast, Lower Mississippi Valley and Texas, precipitation deficits continue to increase.

December is typically a drier time of year for the Upper Midwest and Northern to Central Great Plains.

Since the beginning of October, precipitation has generally averaged below normal across the Central Rockies, Great Basin, Southwest and southern California.

Northwest California and much of the Pacific Northwest have experienced wetter-than-normal conditions.

When it comes to severe or extreme drought, parts of the Northern Plains, the Southwest and the Tennessee Valley fall in those categories. Portions of the Midwest are now considered D1/moderate drought, and one-fifth of Indiana is in D2/severe drought.

Looking at various crop production areas, the following are currently affected by drought:

Barley, 35%
Corn, 54%
Cotton, 18%
Durum wheat, 70%
Peanut, 29%
Rice, 15%
Sorghum, 31%
Soybean, 47%
Spring wheat, 33%
Sugarbeet, 48%
Sunflower, 78%
Winter wheat, 27%

While the drought monitor looks longer term, NASA’s root zone soil moisture map shows just how dry it is in the top 3’ of soil across the Corn Belt and Southwest.

Eric Snodgrass, principal atmospheric scientist at Conduit Ag, says the current La Nina is weak and fading, but it continues to influence weather patterns, which is sending warning signs for spring.

Snodgrass says we’re missing one important component in the atmosphere — the subtropical jet stream, which comes from Hawaii.

“We have the polar jet in place that will drive really cold air into the New Year, especially into the eastern two-thirds of the country, really cold air for probably a while,” Snodgrass says. “Until we crank the jet stream out of the Southwest, it’s hard to return a lot of moisture and break the fear of drought spreading from Mexico or from the western High Plains, which I think is where it’s going to come from next year.”

Snodgrass is worried about drought for two reasons:

Drought conditions are developing in Mexico, the western Plains, the High Plains and all the way up to Canada.
In six of the past 10 years with a really dry fall, the spring to follow was also dry. That causes concern for a big chunk of the Plains and into the Midwest.

Snodgrass says the best opportunity for a pattern shift would be if La Nina breaks down in the next few weeks and transitions to a more neutral pattern heading into spring.

What The Trump Administration's Mass Deportation Plans Could Mean for Agriculture

Mon, 23 Dec 2024 17:39:39 GMT

Farmers and food industry leaders are warning that President-elect Donad Trump’s plans to deport millions of immigrants could devastate agriculture — an industry in which immigrants make up a good chunk of the workforce.

Nearly half of all farmworkers are undocumented, and industries such as dairy and meatpacking plants are especially vulnerable to labor shortages.

“Admittedly, there are some people who slip through,” says Scott VanderWal, vice president of the American Farm Bureau Federation. “Perspective employers are required to take documentation that appears to be legal and valid. There are times when that’s not the case and then ICE [U.S. Immigration and Customs Enforcement] comes in and cleans house, the workers disappear and go wherever they take them and the employers are left without help.”

While the H-2A visa program has grown, it only covers seasonal work and cannot replace year-round jobs at meat processing plants and on dairy and pork farms.

“Our packing plants need labor. Many of our farms use temporary visa labor — educated, skilled individuals work on our sow farms,” says Lori Stevemer, president of the National Pork Producers Council. “We have been experiencing an increased number of denials over the past year, which really makes it a challenge to find workers. The H-2A visa doesn’t work well when we have animals that need care 24/7, year-round.”

Experts say mass deportations would disrupt food production, raise prices and jeopardize the stability of U.S. agriculture.

Deportation falls under the Department of Homeland Security. President-elect Trump has selected South Dakota Republican Gov. Kristi Noem to lead that agency.

“With Governor Noem at the helm, she’s going to bring common sense to that discussion and make sure we don’t close businesses, make sure we get everyone in line, get the workforce in line and then make sure we’re following our country’s rules,” says Hunter Roberts, secretary of South Dakota’s Department of Agriculture and Natural Resources.

Meanwhile, farm groups continue to urge for reforms to immigration policies or a guest worker program to secure a stable workforce.

“At the same time as controlling the border, we need to overhaul our labor system,” VanderWal says. “We need to make H-2A apply to your own workers or come up with a decent program that will help.”

We need some type of H-2A visa reform to allow those workers to stay year-round, Stevemer adds.

Even then immigration is likely to continue to be a political hot potato in 2025, and labor shortages will continue to top the list of challenges for agriculture.

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.

Six Questions One Industry Veterinarian Says She Is Asked Most Often About HPAI

Thu, 26 Sep 2024 19:00:28 GMT

The emerging issue of Highly Pathogenic H5N1 Avian Influenza (HPAI) in the U.S. dairy industry changes on nearly a daily basis.

Novonesis (a merger of Chr. Hansen and Novozymes) hosted a webinar on the issue on Friday to update producers, veterinarians and other members of the agricultural community.

“It’s a rapidly evolving situation,” lead presenter, Kay Russo, DVM, Novonesis technical services manager for dairy and poultry, North America, stressed at the beginning of the program.

“I’m getting a lot of questions, and I’m sure everybody on this call has questions. Or if you’re a veterinarian, you’re receiving them,” she said. “Again, this is a rapidly evolving situation, and what may seem correct today may be different tomorrow.”

Here are the six questions Russo said she is most frequently asked, and what her answers to them are – for now. Russo’s answers have been lightly edited for clarity.

Question #1: Is HNAI spreading from cow to cow?

Answer: Initially the thought was that every one of these animals was exposed to the disease from a bird. But at this point, there is some consideration for the fact that this may be spreading laterally. How it’s spreading is still unclear. There is some postulation that the virus is being spread in the milking parlor. Could it potentially be a mechanical spread from cow to cow on the milkers’ hands, or perhaps (on) the milking machines? Is it possible in these parlors where the humidity is high, it’s a warm environment that we’re seeing some aerosolization of the virus, so I would say that’s possible too. But there’s more work that needs to be done. But for all intents and purposes at this time, I would suspect there is some lateral transmission.

Question #2: Why are calves, younger lactation cows and the feedlot cattle not getting sick?

Answer: Ultimately, I don’t know the answer to this. More work needs to be done. The question needs to be answered. Are they truly not getting infected with a virus? Are they resistant to it, perhaps? Or is it that they are getting infected and just not demonstrating the clinical signs? We milk a lot of these dairy cows three times a day, so there’s a lot of eyes on them. In some of these instances, with the calves or in the feedlot cattle, you’re not handling them as often. We need to rely on the science to answer these questions in order to provide guidelines. I keep saying this, and I will continue to say it, we do not know what we do not measure. And we cannot provide guidelines around what we do not know.

Question #3: Is this a risk to humans?

Answer: The short answer is that it can infect humans. I know that in New Mexico, they are offering free testing to individuals that are working regularly with these infected herds. And if they are symptomatic – we’re seeing conjunctivitis and high fevers in some of them –they are being distributed Tamiflu for their use and for their families. This is a rapidly evolving situation, and the people that are working on it are doing everything they can to ensure the safety of those individuals that are most at risk.

Question #4: Is milk safe?

Answer: The FDA has stated the pasteurization process should kill the virus, and we should not see it in any saleable milk.

Question #5: Will this be a market limiting disease outbreak?

Answer: This is the major concern here, folks. These are important markets for us in this country. At this point, this is something that is absolutely a consideration. The goal here is to keep the farms in business.

Question #6: Are dairy farms a risk to poultry operations?

Answer: We’ve seen two commercial layer operations, one in West Texas and one in Michigan, be positive for highly pathogenic avian influenza this week. I know that there’s considerable amounts of work behind the scenes to determine the origin of the virus that caused the outbreak in those situations. Ultimately, in this circumstance, it’s going to be important that the cattle folks and the poultry folks come to the same table and talk and manage through this. We want to be good neighbors. These are two major industries in our country, so it’s important that the dialogue is there and continues so that we can keep (everyone) safe.

Canada To Develop a Foot and Mouth Disease Vaccine Bank

Wed, 11 Sep 2024 14:24:47 GMT

The Government of Canada is continuing to advance its work of protecting animal health by establishing a foot and mouth disease (FMD) vaccine bank, according to a news release from the Canadian Food Inspection Agency (CFIA).

The vaccine bank is a key part of Canada’s response plans to control and ultimately eliminate an outbreak of FMD should it be detected in Canadian animals, CFIA said.

In late August, a Request for Proposal (RFP) was issued by Public Services and Procurement Canada, on behalf of the CFIA, to supply vaccine products to the FMD vaccine bank.

The successful bidder(s) would provide concentrated FMD vaccines that could be rapidly transformed into usable vaccines. Information about the RFP including requirements, criteria, processes and timelines is available to interested bidders on CanadaBuys.

“It’s vitally important that we continue to take steps to protect livestock, and the livelihood of our hardworking farmers, against the threat of animal disease. By creating a dedicated foot and mouth disease vaccine bank, we’re working to reduce the spread of the disease and the impact that a potential outbreak would have on market access for Canadian producers. The announcement marks another step forward in the on-going work of supporting our animal disease preparedness efforts,” said Lawrence MacAulay, Canada Minister of Agriculture and Agri-Food, in the release.

The vaccine bank would help protect Canada from the emerging threat of FMD, maintain public confidence in the Canadian food supply, and help reduce the spread of the disease, should an outbreak occur. An effective and efficient response, including vaccination, will also help mitigate prolonged market disruptions to trade.

Quick Facts

Budget 2023 committed $57.5 million over five years, with $5.6 million ongoing, to the CFIA to establish an FMD vaccine bank for Canada, and to develop FMD response plans.
FMD is a severe, highly communicable viral disease of cattle and swine. It also affects sheep, goats, deer and other cloven-hoofed ruminants but not horses. Many affected animals recover, but the disease leaves them weakened and debilitated.
Canada has been free from FMD since 1952, and strict measures are in place to prevent the disease from entering Canada. FMD is not a public health risk and is not considered a food safety issue.
The CFIA would use a vaccine only in the event of an outbreak to protect animals and help stop the spread of disease. This complements Canada’s current access to vaccines through the North American Foot and Mouth Disease Vaccine Bank (NAFMDVB) ensuring readily available vaccines for Canadian producers.
In Canada, FMD is a reportable disease under the Health of Animals Act, and all suspect cases must be reported to the CFIA.
The CFIA monitors the status of FMD worldwide and has emergency preparedness and response plans ready.

USDA Identifies Ways HPAI H5N1 Has Likely Spread in Michigan Dairy and Poultry Operations

Mon, 17 Jun 2024 22:29:29 GMT

On June 9, the USDA issued a report that summarizes the findings from field epidemiological investigations of disease spread between premises for 15 dairy herds and eight poultry flocks confirmed with HPAI genotype B3.13 in Michigan.

The following information is pulled from the USDA’s 2024 Highly Pathogenic Avian Influenza (H5N1) - Michigan Dairy Herd and Poultry Flock Summary (see Michigan Dairy Herd and Poultry Flock Summary ).

The information offers potential insights for how the dairy and poultry industries in states beyond Michigan likely have been impacted, as well.

A ‘Eurasian Lineage Goose’

Whole genome sequencing (WGS) of viruses from the dairy and poultry premises identified Eurasian lineage goose/Guangdong clade 2.3.4.4b, genotype B3.13 on the Michigan farms and suggests likely indirect transfer of virus from the dairy premises to the poultry premises.

USDA reports that interstate animal movement initially introduced the HPAI genotype B3.13 virus from Texas into a Michigan dairy. However, USDA says the continued disease transmission within Michigan has been determined to be multifactorial.

Transmission between farms is likely due to indirect epidemiological links related to normal business operations such as numerous people, vehicles, and other conveyances frequently moving on and off the affected dairy premises, with many of these indirect links shared between premises.

Importantly, USDA says, disease spread due to independent introduction of the virus onto dairy or poultry premises from migratory waterfowl is not supported based on both genomic and epidemiological data analysis.

Key findings identified to date and potential risk factors for local transmission in Michigan specifically, include:

Shared personnel between premises
o 20% of affected dairies’ employees and 7% of dairies’ employees family members work on other dairy premises

o 7% of affected dairies’ employees also work on poultry premises; 13% of affected dairies’ employees have family members who work on poultry premises

o 31% of dairies have employees who own livestock or poultry at their personal residence

Shared vehicles between premises
o 62% of affected dairy premises use shared vehicles to transport cattle, with only 12% of premises cleaning vehicles before use

Frequent visitors on/off premises
o 100% of affected dairy premises have regular visits by veterinarians, nutritionist/feed consultant, and/or contract haulers (e.g., cattle or manure); the majority of these visitors have direct contact with cattle

o 40% of affected dairy premises have regular visits for deadstock removal, with 20% having direct contact with cattle. Furthermore:

-53% of affected dairies utilized the same deadstock removal company and 40% had animals removed from the premises by that company within 30 days prior to clinical onset

o Milk haulers visit dairy premises, on average, 34 times within a 30-day time period. Furthermore:

-93.3% of affected dairy premises are part of the same milk co-op with at least one other affected dairy premises within the state (i.e., only one of the affected dairy herds is part of a milk co-op that none of the other 14 affected dairy herds belong to)

Disease Spread Between Dairy and Poultry Premises
Apart from the potential for resident wild birds or peri-domestic species to move and transmit the virus, the only other potential transmission routes found from dairy herds to the poultry flocks were through shared employment, housing, or movement of employees.

Approximately 22 employees of three poultry flocks worked weekend shifts at two different dairy premises. Shared housing between dairy and poultry workers was identified between three poultry premises and two dairy premises. It is also possible that dairy employees have social contact with poultry premises employees, USDA reports.

In Summary
The investigations discussed in this report, including the respective WGS information, indicate that HPAI H5N1 genotype B3.13 was introduced into Michigan through animal movement from Texas and subsequently spread within the state between dairy premises with spillover into poultry premises through multiple possible routes.

Factors that appear to be of greater risk for introduction into a dairy premises may be mitigated through enhanced biosecurity, increased animal testing, and potentially through within-state animal movement restrictions if they can be implemented without impacting animal welfare.

USDA says the willingness of Michigan producers to participate in these investigations has greatly increased the body of knowledge of HPAI H5N1 B3.13 detections in Michigan and throughout the nation; this report could not have been completed without them.

US to Test Ground Beef in States With Bird-Flu Outbreaks in Dairy Cows

Mon, 29 Apr 2024 19:59:33 GMT

The U.S. government said on Monday it is collecting samples of ground beef at retail stores in states with outbreaks of bird flu in dairy cows for testing but remains confident the meat supply is safe.

Federal officials are seeking to verify the safety of milk and meat after confirming the H5N1 virus in 34 dairy cattle herds in nine states since late March, and in one person in Texas.

Both the Centers for Disease Control and Prevention and the World Health Organization have said the overall public health risk is low, but is higher for those with exposure to infected animals.

Scientists believe outbreaks are more widespread in cows than officially reported based on findings of H5N1 particles in about 20% of milk samples. The U.S. Food and Drug Administration said on Friday that preliminary results of gold-standard PCR tests showed pasteurization killed the bird flu virus in milk, though.

The U.S. Department of Agriculture will analyze retail ground beef samples with PCR tests that indicate “whether any viral particles are present,” according to a statement. Some
dairy cows are processed into ground beef when they grow old.

The USDA on Monday began requiring lactating dairy cows to test negative for bird flu before being moved across state lines as officials seek to contain the virus.

The department said this weekend that testing is not required for cows that are shipped over state lines directly to slaughter facilities from barns where they are sold. Those
cattle only need documentation showing they were inspected by a veterinarian.

The USDA said it inspects each animal before slaughter, and all cattle carcasses must pass inspection after slaughter to enter the human food supply.

Last week USDA said it had found bird flu in a lung tissue sample from an asymptomatic dairy cow that was sent to slaughter from an infected herd. The animal did not enter the food supply, according to the department.

The USDA is now collecting beef muscle samples at slaughter facilities of dairy cattle that have been condemned to determine the presence of viral particles, according to the statement. Any positive PCR tests for retail or slaughter samples will be evaluated for live virus, the USDA said.

The USDA will also use a “virus surrogate” in ground beef and cook it at different temperatures to determine how the virus is affected, according to the statement. It said cooking meat to a safe internal temperature kills bacteria and viruses

Colombia restricted the import of beef and beef products coming from U.S. states where dairy cows have tested positive for avian influenza as of April 15, according to the USDA.

There are no known cases of bird flu in beef cattle so far.

The human case in the current outbreak was in a Texas farm worker who suffered conjunctivitis following exposure to dairy cows.

A Message to the Ag Industry about H5N1

Fri, 26 Apr 2024 20:49:16 GMT

“We’re going on a bear hunt. We’re going to catch a big one… We’re not scared.”

So goes a beloved children’s book written by Michael Rosen. The story is a metaphor for how to address fear. Kay Russo, DVM, often reads it to her son and daughter, ages 4 and 6.

“This unfortunate family seems to deal with a lot of issues as they’re going on their hike,” Russo says. “Ultimately, every time they reach one of these issues, the book basically says, ‘You know, we can’t go over it. We can’t go around it. We can’t go under it. We have to go through it.’”

That story illustrates how the dairy industry must deal with the growing impact of H5N1, says Russo, Novonesis technical services manager for dairy and poultry. She’s watched the spread of the virus with alarm and urges U.S. leaders across dairy and agriculture to step up and take action.

“Address it head-on,” she says. “Don’t hide.”

As with all major threats, she says ag needs a comprehensive, cohesive plan to address the virus in dairy – and to also look at how to protect the beef, pork and poultry industries.

“At this point, I believe it’s important to take one day at a time and systematically answer the questions that we need to get answered in order to define a sustainable path forward,” Russo says.

“We have a very clear picture that it’s in the udder and is being shed in milk. But where else do we need to be concerned? That matters because that is going to define the control tactics to reduce spreading it from cow to cow. Those questions are ultimately going to be the pillar of our understanding and help to define strategies for controlling the virus in a sustainable way.”

On The Front Line
Help can’t come soon enough for dairy producers and veterinarians in the trenches working with cows.

Veterinarians such as Dr. Barb Petersen in Texas have been dealing with the virus in their clients’ dairy herds since at least March.

“It has been circulating here as early as February, based on retrospective feedback from owners and fellow veterinarians,” says Petersen, owner of Sunrise Veterinary Service in Amarillo.

By early March, she had begun sending daily emails and text messages to her Texas Panhandle dairy clients who needed answers and support.

Petersen, who has been in practice 15 years, did her best to provide both. But she didn’t know what she was dealing with. Neither did any other veterinarian Petersen reached out to within 200 miles of her practice.

“We started to text and email each other, and give summaries of ‘OK, here’s the test that this doctor has run. Here’s what another colleague has run,’” Petersen recalls.

“We tested for every single viral bacterial mycotoxin, lepto, rumensin toxicity, nitrates… I mean, you name it, every single thing that we vaccinate for, we tested for, for sure, right off the bat. And then even some of the things that we don’t or can’t vaccinate for. We tried to cast a really wide net.”

None of the initial tests, conducted by the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL), provided an answer.

Recurring Symptoms Emerge

Some members of the animal health community suspected winter dysentery – an acute, highly contagious gastrointestinal disorder that can affect housed dairy cattle of all ages.

Petersen was skeptical.

“The first clinical symptom I saw was cows that had indigestion. They had manure that wasn’t well-digested, manure with particles of feed in it,” she says.

As she checked more cows and talked with colleagues, more information came to light and she began to identify recurring symptoms: thick, colostrum-like milk; lesions on cow vulvas; high temperatures; respiratory distress; a drop in feed consumption; and a corresponding lack of rumination. None of it added up to winter dysentery.

“This is a really strong and fierce reminder to keep your hands on the cows,” Petersen says. “It’s wonderful to have data, but you have to trust and then verify.”

When Russo at Novonesis got news of the problem from a colleague, she called Petersen.

Russo has worked as a dairy veterinarian and is also a board-certified poultry veterinarian. She and Petersen discussed what kinds of tests had already been done and what health concerns had been ruled out.

“I said, ‘You know, I may sound like a crazy person, a tinfoil-hat-wearing person, but this sounds a bit like (highly pathogenic avian) influenza to me. We’ve seen this particular strain of influenza that’s been circulating, that’s been jumping into mammalian hosts,’ and I kind of left it there,” Russo recalls.

More conversations between Russo, Petersen and other veterinarians ensued. Russo encouraged Petersen to collect some of the dead birds she had encountered at the dairies and submit them to TVMDL for testing, which she did.

On March 19, Petersen received a call from the Texas lab, confirming the wild birds were positive for H5N1.

At about the same time, barn cats at the dairies Petersen worked with were getting sick and starting to die. They had consumed some of the H5N1-infected birds and milk that had not been pasteurized.

“I spent one weekend picking up dead birds and the next weekend picking up dead cats. It was very sad,” Petersen says.

Science Provides Answers
Petersen sent some of the dead cats and a pooled sample of milk to TVMDL pathologists for testing. Because of their heavy workload, she sent the same material to a former veterinary classmate at Iowa State University (ISU), Dr. Drew Magstadt, now a pathologist at the school’s diagnostic laboratory.

“Whenever I’ve gotten into a real jam professionally – like, you have a question that you can’t seem to find an answer to – the group of folks that have always helped me solve it have been pathologists,” Petersen says. “It’s been pathologists that I could give the clues to who helped finish the puzzle.”

On a warm March night in Amarillo, Petersen sat resting on her back porch at home when a text message from Magstadt popped up on her phone.

“There’s something in the results,” he wrote. “Can I call you?”

On the phone, Magstadt shared what he’d found in the lab tests done on the cats and milk: H5N1.

“I was like, ‘Are you serious?’” Petersen asked Magstadt. “Are you going to run those tests again?”

“Yes,” he said. “Just to make sure.”

The initial H5N1 confirmation flabbergasted Magstadt. The next day, he retested the samples to confirm the finding.

“I had thought we would find the results were negative and we would move on to other testing. So I was very, very surprised when the results came back positive,” says Magstadt, ISU clinical associate professor and a pathologist at the Iowa State Veterinary Diagnostic Laboratory.

The National Veterinary Services Laboratory (NVSL) then confirmed Magstadt’s findings. The documentation of H5N1 by NVSL in a sample of milk from a dairy cow represented an industry first.

“The most surprising part of this, in my mind, is the fact that we’re finding so much virus as we are in the milk, in the mammary gland,” Magstadt says.

‘Show Us The Data’
On April 23, the U.S. Food and Drug Administration (FDA) reported it had detected “viral particles of H5N1 avian influenza” in pasteurized milk available for purchase at grocery stores.

Russo is quick to point out this doesn’t mean the actual virus is in milk. Rather, it’s the genetic material known as RNA.

“I think the FDA needs to show us the data,” Russo says. “The fact that there is viral material in some of the milk on shelves, as detected by rt-PCR. That test doesn’t say whether it is alive or dead. Virus isolation is necessary. The first tests have not grown virus, thankfully, but we need more data.”

No unusual human illnesses have been documented. Government health officials say they have seen nothing unusual in flu activity, according to a senior official at the Centers for Disease Control and Prevention (CDC) who was interviewed for this story. The overall assessment and risk to human health remains low from H5N1, the official says.

“CDC looks for a host of flu-like symptoms,” he told “U.S. Farm Report” host Tyne Morgan during a phone interview. “They do so by looking at people coming into emergency rooms, care systems, etc.”

Yet anecdotal evidence suggests the people most likely to be infected – dairy farm workers who have their hands on cows regularly – aren’t necessarily going to doctors for treatment.

The World Health Organization (WHO) website references just one “laboratory-confirmed case of human infection with an influenza A (H5N1) virus on 1 April 2024” on a dairy farm.

“It’s a mild, mild case and the only symptom he had was pinkeye,” Sid Miller, state commissioner of the Texas Department of Agriculture, told “AgriTalk” host Chip Flory at the time, as reported on AgWeb.

That Texas case marked the second confirmed human case of influenza A(H5N1) detected in the U.S. — and the first in the dairy industry. The first documented case, identified in 2022, involved a person in Colorado who worked with infected poultry that tested positive for the virus.

During his interview with Miller, Flory asked whether the virus could impact beef cattle at some point.

“You’ve seen what’s happened in the cattle markets,” Flory said. “They’re looking at it like this is a major problem for beef.”

Problems aren’t anticipated for Texas beef cattle, which consist primarily of feedlot cattle in the Panhandle, Miller replied.

“The cattle that get it are the older lactating cows, and we don’t have those in the feedlot,” Miller explained. “I think we’re OK, but we’re certainly going to research that.”

Tip Of The Iceberg?
So far, H5N1 has been officially confirmed in only 32 herds in eight states, according to data from USDA’s Animal and Plant Health Inspection Service (APHIS).

Some veterinarians working with dairies in Texas believe the virus is more active than current data suggest. Nick Schneider, a consulting dairy practitioner, is one of them.

“The thing is, when you get into the Panhandle of Texas, I’m not sure there’s anybody (dairy farms) that did not have it,” says Schneider.

Texas is home to 335 Grade A dairies with an estimated 625,00 cows, according to information on the Texas Association of Dairymen website. More than 100 of those operations are in the Panhandle.

The virus likely is being under-reported by the dairy industry because the presence of the virus in dairy cows is new, and there are no reporting requirements, Russo says.

“It’s not a foreign animal disease like it’s considered in poultry, where there are reporting requirements,” she explains. “This is considered an emerging disease (in dairy cattle).”

The dairy industry needs to be “very forward looking” now and address the virus, advises Schneider, the Texas dairy consultant.

“Looking at what happened in the rearview mirror is great, but if you’re not looking at where you’re going, it’s really just a pointless endeavor,” he says.

To that end, he advises gaining insights and expertise in preparation for whatever new information emerges next.

“We need to think about this potentially being something we have to live with, as being a part of the industry in the future,” Schneider says. “I hope I’m wrong. I would love to be wrong about that. But it’s something that we definitely need to consider when we’re thinking of how we’re going to manage it.”

Lessons From Swine And Poultry
Russo also advocates learning the lessons from swine and poultry, which have faced a variety of viral challenges for years.

“It’s important that we don’t try to reinvent the wheel as the cattle industry, but sort of cross the aisle to interact with the poultry folks and the swine folks who have gone through this repeatedly over the years and learn from the defined principles they use and try to adapt them into the bovine space,” she says.

Both swine and poultry have modified their animal management practices from the farm to the marketplace as a result of those experiences.

“Poultry, for instance has very distinct biosecurity principles they abide by to include lines of separation,” Russo says. “One is they keep the outside world out. Another is their use of PPE (physical protective equipment) to protect employees and also the birds from anything that might be carried onto the farm.”

The latter is a message Dr. Barb Petersen has taken to heart. Petersen says she was exposed to H5N1 for more than a month before she learned about the virus and its ability to infect dairy cows and people.

“I’m very fortunate that I never got sick,” she says.

Her advice? “Protect yourselves and your people on the dairy. There’s been underreporting of the virus. Understandably, there’s been a lot of fear. But every dairy that I’ve worked with has – with the exception of one – had sick human beings at the same time they had sick cows.”

Based on that knowledge, Petersen has acquired PPE available through Texas Health and Human Services.

“All the states have personal protective equipment available. Go and get it for your dairies,” she encourages other veterinarians. “If a dairy is on the fence, just provide it to them, offer it to everybody.”

Petersen says she has worked with people infected by H5N1 who do not interact with dairy cows. “I’m talking owners and feeders who don’t usually touch cows,” she says.

Research is underway to determine how much of a health risk the virus poses to humans, Russo says.

“This is a rapidly evolving situation, and the people that are working on it are doing everything they can to ensure the safety of those individuals that are most at risk,” she says.

A Paradigm Shift
The virus continues to hit the U.S. poultry industry hard.

Cal-Maine Foods, the largest producer and distributor of fresh shell eggs in the U.S., announced April 2 that chickens at its facility in Parmer County, located in the southwest part of the Texas Panhandle, tested positive for the virus. As a result, Cal-Maine had to cull nearly 2 million chickens − 1.6 million hens and 337,000 pullets.

In the AgriTalk discussion aired earlier this spring, Flory asked Miller, the Texas ag commissioner, whether he believes state agriculture department investigators are in front of the latest issues with HPAI in dairy cattle.

“I think so,” Miller replied. “We’ve got about 10 months before the ducks and geese come back, so I think we’ll have it figured out by then.”

Moving forward, the U.S. livestock industry might operate in a new world – one where the H5N1 virus is endemic.

Russo is undaunted by the challenge.

“This is not insurmountable, but it’s an issue we need to address swiftly,” she says.

Culled dairy cows going into the food supply deserve special attention, she says.

“We need to do the work so that we can define those movement strategies for the practitioners that are being asked to write health certificates on these farms that have the virus circulating,” Russo says.

The dairy industry needs to be more proactive for the sake of the poultry industry, she adds.

“Putting our heads in the sand, and hoping it burns itself out is not going to work. It’s just not,” she says. “It would take down the entire poultry industry by doing that, because this is highly pathogenic to them.”

That is not hyperbole, Russo says: a dime-sized piece of manure with H5N1 can infect up to 1 million chickens or turkeys.

In essence, the livestock industry needs to go on a bear hunt, as the children’s story says.

‘We can’t go over it. We can’t go around it. We can’t go under it. We have to go through it.”

With that as the focus, solutions to H5N1 can be found and help delivered to livestock producers and veterinarians on the front lines and, ultimately, the U.S. agriculture industry can insure a safe food supply.

The South Dakota Department of Agriculture (DANR) and the Animal Industry Board (AIB) have received confirmation from the United States Department of Agriculture’s (USDA) National Veterinary Services Laboratory (NVSL) of the detection of highly pathogenic avian influenza in a dairy cattle herd in South Dakota.

This is the first confirmed case of HPAI in a dairy operation in South Dakota.

“South Dakota Dairy Producers encourage all dairy producers to closely monitor their herd and contact their herd veterinarian immediately if cattle appear symptomatic,” said Marv Post, Chairman of South Dakota Dairy Producers, in a prepared statement. “USDA continues to emphasize that pasteurization kills the virus and that milk and dairy products are safe to consume.”

Texas-Sized Problems Hit the Lone Star State, but Ag Commissioner says ‘Things are Getting Better’

Thu, 04 Apr 2024 21:26:34 GMT

Already this year, farmers and ranchers based in the Texas Panhandle have dealt with some Texas-sized problems that have impacted their livelihoods.

In March, the Smokehouse Creek Fire burned more than a million acres and killed thousands of cattle, primarily in the Panhandle and in Oklahoma.

Cal-Maine Foods, the largest producer and distributor of fresh shell eggs in the U.S., announced on Tuesday that chickens at its facility in the southwest part of the Texas Panhandle, in Parmer County, tested positive for highly pathogenic avian influenza (HPAI). As a result, Cal-Maine had to cull nearly 2 million chickens − 1.6 million hens and 337,000 pullets.

Dairy producers in the Texas Panhandle have also grappled with outbreaks of HPAI in their cow herds in recent weeks. To date, the USDA has confirmed the H5N1 strain of HPAI in dairy cattle on seven Texas farms.

In addition, one dairy worker has contracted an HPAI infection and displayed mild symptoms, the Texas Department of Health and Human Services reported Monday.

“It’s a mild, mild case and the only symptom he had was pinkeye,” Sid Miller, state commissioner of the Texas Department of Agriculture, told AgriTalk Host Chip Flory on Thursday. Miller said it’s unknown how the individual was infected.

What’s Going To Happen Next?
Flory asked Miller whether he believes state agriculture department investigators are in front of the latest issues with HPAI in dairy cattle.

“I think so,” Miller replied. “We’ve got about 10 months before the ducks and geese come back, so I think we’ll have it figured out by then.”

Miller speculated that waterfowl caused the dairy and poultry HPAI infections.

“Cowboy logic would tell you that cattle were drinking from the same ponds where waterfowl were present,” he said. “Or, maybe waterfowl had been in the feed boxes eating grain or something (along those lines). So, we’ve got to take better biosecurity measures to make sure that we eliminate all those possibilities.”

Despite the challenges Texas agriculture has faced the past few months, Miller is cautiously optimistic.

“Things are turning around and getting better. They really are,” he said.

One concern the livestock industry has now is whether HPAI will impact beef cattle at some point.

“You’ve seen what’s happened in the cattle markets,” Flory said. “They’re looking at it like this is a major problem for beef.”

Miller replied that he doesn’t anticipate there will be an HPAI problem in Texas beef cattle, which consist primarily of feedlot cattle in the Panhandle.

“The cattle that get it are the older lactating cows, and we don’t have those in the feedlot,” Miller said. “I think we’re OK, but we’re certainly going to research that.”

Food Safety Precautions
Miller said one of the Texas Department of Agriculture’s primary responsibilities is to make sure food produced in the state is safe for consumers. None of the affected milk, meat or eggs ever reached the marketplace.

“If you want to take some precautions, you might lay off the raw milk and unpasteurized dairy products, because that’s about the only way (HPAI) could get there,” Miller said. “But it’s not in the food chain. It’s not going to create a shortage of milk and dairy products. There’s no shortage of eggs. So, consumers, just rest assured. Don’t be alarmed. This is really not going to affect you.”

In a statement last week, the Centers for Disease Control said it considers the human health risk to the U.S. public from the virus to be low, though people who work with livestock are at higher risk of infection. The agency also advised against eating unpasteurized dairy products, such as raw milk or cheese, from animals with suspected or confirmed cases of HPAI.

House Passes Bill to Preserve Veterinary Use of Xylazine

Wed, 13 Dec 2023 20:45:55 GMT

The House of Representatives passed the Support for Patients and Communities Reauthorization Act on Tuesday. The Act, in part, fights the illicit use of xylazine in humans while preserving access to the drug for use in animals.

“For beef packers, xylazine is used to quickly and humanely sedate sick or injured cattle in a manner that can safely and effectively be administered by workers. Xylazine has both animal welfare and worker safety benefits at beef plants, and there are no equally safe and effective alternatives,” said Meat Institute President and CEO Julie Anna Potts.

Xylazine is used to a lesser degree in pigs than in beef. “But it is an issue for vets in general as DEA schedule drugs are a huge hassle and really limit access. It is one more limit on what we can do,” Jim Lowe, DVM, associate dean of Online Programs and Extension at the University of Illinois College of Veterinary Medicine told Farm Journal’s Pork earlier this month.

At issue is the concern that xylazine, a drug approved by the U.S. Food and Drug Administration for use in animals, is being imported illegally in powder form and added to fentanyl. Xylazine is not approved for human use.

The Combating Illicit Xylazine Act was included in the Support for Patients and Communities Reauthorization Act, H.R. 4531, approved by the House with a vote of 386-37.

“We appreciate the hard work of Congressmen Jimmy Panetta (D-CA) and August Pfluger (R-TX) and the Energy and Commerce Committee for including the xylazine measures in the bill passed by the House with strong bipartisan support,” said Potts. “We now call for swift Senate consideration.”

The bill will ensure the Drug Enforcement Agency (DEA) has the power to stop the illegal flow of xylazine to humans, while allowing its continued access for veterinary purposes.

Xylazine Bill Protects Veterinary Access to the Sedative

Protect Your Calves During Fly Season

Tue, 17 May 2022 15:18:17 GMT

With fly season at its peak, calves need extra protection to stay healthy and stress-free.

Stable flies are particularly damaging to calves, because their painful bites on the lower legs are stressful and damaging to calves’ tender skin. Sarah Morrison, researcher at the W.H. Miner Institute, Chazy, NY, said the damage from stable flies can be severe enough to cause noticeable hair loss and scab formation. “Stable fly populations will increase throughout the summer, and have the greatest numbers by the end of August and early September,” noted Morrison.

Biting flies like stable flies also have been identified as a vector that can spread vesicular stomatitis , which is a growing concern in the southwestern U.S. Common houseflies are more of an annoyance but also can spread diseases, and have been recorded in populations as much as 8-fold greater than stable flies.

“Unfortunately, calf housing is an awesome breeding ground for fly populations on the farm,” said Morrison. “Fly maggots grow and develop in accumulations of manure; spilled grain and milk; other spoilage piles; and straw bedding.”

She noted an Integrated Pest Management (IPM) plan can be helpful in minimizing fly populations and protecting calves from their damage. IPM focuses on (1) sanitation; (2) biological control; and (3) chemical control. For IPM in calf environments, she advised:

Sanitation – Clean pens weekly and remove excess manure regularly. Mow areas around calf hutches, and elevate hutches to encourage airflow and keep bedding dry. Consider sand, gravel or sawdust as bedding materials instead of straw in warm-weather months.

Biological control – Releasing natural predators in the spring can help keep fly populations from blooming. These natural enemies include black soldier flies, rat-tailed maggots, beetles, mites and wasps.

Chemical control – Chemical sprays should be rotated to prevent insect resistance. Larvicides can be used in heavy breeding areas such as manure storage, but should be used with caution because they also destroy beneficial insect populations. Oral, feed-through larvacides are especially helpful in managing fly populations in calf environments. Baits and traps also are useful in lowering adult fly populations throughout the farm.

“A whole-farm approach should be taken to maximize fly control, and also will positively impact the calf-rearing area,” said Morrison. “Plus it also creates a more pleasant environment for the people caring for the animals.”

‘Moisture Opportunity’ Is On Its Way To The Plains

September was one of the driest months on record for parts of the Midwest, and October has continued the dry trend, said Chip Flory, host of AgriTalk, on Tuesday’s show. He asked guest John Homenuk of Empire Weather Consulting, what shut the moisture off in the middle of the country.

“We’ve had this ridge in place since September, which we’re fortunate didn’t happen in late July and August,” Homenuk told Flory. “We’ve kind of been in this really poor cycle for moisture for several weeks.”

Homenuk said parts of the U.S. have been in a fairly weak La Nina weather pattern, which he expects will “oscillate up and down a bit” throughout this fall and into the 2024-25 winter months.

However, Homenuk does anticipate some limited moisture will start to move back into Midwest weather forecasts soon.

“For instance, late this weekend and early next week, we have a moisture opportunity coming into the Plains,” he said. “A low-pressure system could spread out of the Intermountain West into the foothills, and eventually bring some moisture to places like the Texas Panhandle, Kansas and Nebraska. That’ll be the first system to come out, and there might even be some scattered showers across parts of the Midwest early next week.”

Meteorologists anticipate weather patterns will continue to lean toward more moisture as November gets underway.

“It’ll be a slow go of it, but the feeling is that we’re through the worst of the dryness now, and we’ll start working back gradually into a more normal pattern,” Homenuk said.

Looking Ahead To Next Spring

Flory asked what kind of weather pattern farmers can anticipate going into the 2025 cropping season.

“There is some indication already on models that we’re going to split up again, between a La Nina and El Nino,” Homenuk said. “Some of the indications stay near neutral, so not a La Nina or El Nino, and some of them start actually sending us back into El Nino by spring and summer of next year. I think we need to get through the next couple of months before we really have an inclination of where it’s going to go next year.”

Flory said he’s concerned, given the weather conditions this fall, that next spring will be a dry one.

“It’s kind of common to hear people say, ‘droughts don’t start in the year that they happen. They start in the fall before.’ And I think there’s more than a few producers out there that are concerned that this drought we’ve got in the middle of the country is going to continue on into the spring of next year,” Flory explained.

Homenuk said he believes if the U.S. transitions back to an El Nino weather pattern by spring, that should be generally viewed as a good thing.

“That would reintroduce some more moisture. If we stay neutral, or we stay in a weak La Nina into the spring, then I think those lingering drought concerns could make their way into the growing season in 2025,” he added.

Weather Outlook For South America

Flory asked what kind weather South America, Brazil and Argentina in particular, will see for its growing season.

“We’re kind of into this weak La Nina scenario,” Homenuk said. “What tends to happen down there in South America is you get a little bit of a mixed bag. So, it was a slow start over the last couple of weeks, but now we’re seeing a pattern change across central Brazil, essentially Mato Grosso southward, where there’s moisture coming into the forecast over the next several weeks.”

He added that the same could likely be said for northern Argentina.

“If you look at the next 15 to 30 days, the moisture forecast is actually pretty solid. They have some ground to make up, given how dry it was before. But I think these weak La Ninas tend to be OK in those regions. It is a kind of pattern indicating that there will be some moisture around it. I think they’ve avoided the worst-case scenario, which would have been a really strong La Nina developing.”
