Avian flu strikes more poultry flocks in 7 states and more cats

By

As H5N1 avian flu outbreaks in commercial and backyard poultry across the United States continue at a brisk pace, the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) has reported a few more detections in domestic cats.

Also, APHIS confirmed 5 more detections in dairy cattle, all from California, and more than 50 in wild birds across several states.

Commercial and backyard farms hit

Over the last 2 days, APHIS reported the virus in more poultry flocks across seven states, with several involving commercial farms.

In hard-hit Ohio, outbreaks were confirmed on four more layer farms and three more turkey farms. And in neighboring Pennsylvania, the virus struck five more commercial farms.

Elsewhere, outbreaks struck two more farms in Missouri, including a turkey farm in Lawrence County and a broiler farm in Newton County.

Meanwhile, federal officials confirmed findings at two more live bird markets in New York’s Queens and Bronx counties. Earlier detections at live markets in Queens, the Bronx, and Brooklyn prompted New York’s governor last week to announce a temporary closure of live bird markets in New York City, Westchester, Suffolk and Nassau counties.

APHIS also reported new outbreaks in backyard flocks in Louisiana’s Calcasieu County, Washington’s Mason County, and Connecticut’s New London County.

Since the virus first emerged in US poultry in early 2022, outbreaks have led to the loss of a record 157.7 million birds across all 50 states and Puerto Rico.

With detections continuing in domestic and wild birds, the Michigan Department of Agriculture and Rural Development today urged poultry owners to continue to take steps to protect their birds, especially as wild birds begin their spring migration.

Officials added that though it’s impossible to predict what will happen in the spring, “it is certain that this disease will continue to impact Michigan’s animal agriculture, and taking preventative measures to keep HPAI [highly pathogenic avian influenza] away from domestic birds remains essential.”

More detections in cows and wild birds

In related developments, APHIS confirmed 5 more detections in dairy cattle, all from California. The latest additions lift the national total to 962 and California’s total to 744.

The virus also continues its heavy toll in wild birds. APHIS today added more than 50 H5N1 confirmations to its list of birds found dead in several states, which includes gulls, geese, ducks, and birds of prey.

The list also includes hunter-harvested and live-sampled waterfowl from states including Louisiana, Indiana, Arizona, Nebraska, Oregon, and Michigan.

Virus strikes more domestic cats in 3 states

APHIS today confirmed three more H5N1 detections in domestic cats, which includes an infected stray cat in California’s San Mateo County announced by county officials on February 6. The cat was taken in for medical care by a family in Half Moon Bay when it developed symptoms. It’s not known how the cat was infected, and the animal was euthanized due to its condition.

The other confirmations involve a cat from Montana’s Flathead County that was sampled on December 5, 2024, and a cat from Oregon’s Multnomah County that was sampled on February 3.

Lakeview Poultry LLC in Versailles, Mo., was one of three farms across the U.S. to receive the U.S. Poultry & Egg Association’s (USPOULTRY) Family Farm Environmental Excellence Award during the 2025 International Production & Processing Expo in Atlanta. USPOULTRY sponsors the annual awards for exemplary environmental stewardship by family farmers engaged in poultry and egg production.

Applicants were rated in several categories: nutrient management planning, implementation of novel sustainability practices, community involvement, innovative litter or manure management techniques, and participation in education or outreach programs. A team of environmental professionals from universities, regulatory agencies, and state poultry associations reviewed applications and conducted farm visits.

Kenneth and Elaine Nolt have raised four 13,000 bird flocks of tom turkeys per year for the past 20 years. Kenneth’s interest in raising turkeys originated at an early age when a co-worker began raising turkeys for Cargill. It would take years, but Kenneth’s calling to work in the turkey industry was finally realized when Kenneth, Elaine and their three children moved back to Missouri in 2004.

With sustainability in mind, in 2020, Kenneth installed 80,000 BTU quad stoves to better control heat within the barn. Through this upgrade, the Nolts have seen a 20% increase in fuel efficiency. Kenneth also installed automatic vents and a curtain pocket to reduce fan run time and propane usage. As lighting is so important to turkey performance, in 2023, Kenneth implemented LED lighting to improve the well-being of the turkeys and increase energy efficiency.

To track and maintain the health of the soil on his farm, Kenneth regularly tests his soil. By measuring the nitrogen, phosphorus and potassium levels, Kenneth can make educated management decisions to enhance his soil performance. Careful not to overapply nutrients, these soil tests provide Kenneth with guidance on when and how much litter is sold to litter brokers for use on neighboring farms.

Practicing smart farm stewardship, Kenneth’s family focuses on the health of the farm’s ecosystem. This past summer, the Nolts’ youngest son built his own honeybee hive. Besides raising bees for honey, they understand the benefits that native pollinators provide for a variety of agricultural crops and native plants. This implementation on the farm will provide pollinators with the opportunity to increase their population while also expanding biodiversity. This is a project the Nolts hope to continue and expand.

Bill Griffith, chief operations officer for Peco Foods and USPOULTRY vice chair, presented the award to the Nolt family.

Count Your Eggs Before They Crack: Coverage Options in the Event of a Poultry Crisis

By
Sophi Fairman

The recent surge in the cost of eggs because of the avian influenza (bird flu) is impacting many consumers. Multiple grocery store chains have implemented limitations on the amount of eggs a customer can buy and restaurants have imposed surcharges on menu items with eggs. Consumers, however, are not the only ones feeling the economic impact of the ravage to poultry flocks, poultry farmers and producers are also feeling the financial strain. As we have explained in the past, insurance can help mitigate the risks to poultry farmers and producers associated with these kinds of events. Here, we explore how some types of coverages can help protect poultry farmers and producers who face unexpected events, such as those stemming from illness or contamination of a flock, that disrupt operations or cause a business loss.

Poultry-Related Risks Coverage

Poultry farm insurance is meant to protect poultry farming operations from an array of losses because of damages to equipment and property; and the death, injury or illness of the birds. Insurance products specific to poultry risks can also cover animal loss and loss of production due to diseases. Poultry insurance can also protect against unexpected mortality (like sudden death due to a farming accident or natural disaster), theft, contamination and flock repopulation costs. Insurance for poultry farmers and producers is also available in certain livestock policies, which also cover some risks associated with poultry farming.

Disease & Contamination Coverage

Disease or contamination insurance covers losses resulting from the outbreak of diseases, like bird flu and salmonella, that can affect the egg-production process. Some policies include coverage for flock culling (the process of removing birds from a flock and often later replacing them) to prevent the spread of a disease or illness within a flock. In some cases, coverage may even be available for costs of treatments for ill birds and for sanitizing a poultry farm before bringing new birds in. Disease or contamination coverage may also cover costs for poultry farmers and producers who face egg recalls and government mandates to destroy an egg supply due to contamination or suspected contamination.

Business Interruption Coverage

Business interruption coverage protects against income losses. Often, this type of insurance also covers the additional costs of keeping a business running after an interruption caused by events like supply chain issues, natural disasters and potential disease outbreaks. In some instances, business income insurance also covers lost income due to direct loss of a poultry farming operation. Some insurance offerings also protect against risk of loss due to market conditions that impact livestock businesses and owners considering events like the bird flu. For example, “gross margin” insurance policies, which are part of a federal risk-management program, protect against the loss of gross margins when costs to feed and care for animals exceeds the market value of the animals. Notably, however, business interruption coverage may require a showing of direct physical loss to insured property, which may vary depending on the policy. In this regard, insurers might also attempt to apply pro-insurer rulings from cases arising from the Covid-19 pandemic that interpret the meaning of “physical loss or damage” to limit what otherwise would have been a covered business interruption loss arising from bird flu-related issues. Instances of such insurer conduct have already been seen in cases involving smoke damage from California wildfires.

Key Takeaways

Poultry farming involves many unique risks, from disease outbreaks and egg recalls, to devastation resulting from severe weather conditions. For that reason, it is key for farmers and producers in the poultry industry to understand the various insurance products and unique elements associated with events that can impact their flocks and their finances. As a best practice, poultry businesses should assess potential risks of loss early and identify which insurance offerings can maximize their coverage options if their flock and farm operations are impacted by an event that leads to a loss.

Lawmakers Push to Block USDA’s Proposed Salmonella Rule

By
Sophi Fairman
-

A new bill introduced by Representatives Steven Womack of Arkansas and Tracey Mann of Kansas aims to halt the USDA’s efforts to implement a proposed regulation addressing salmonella in raw poultry. If enacted, the legislation would prevent the agency from finalizing or enforcing the rule.

Initially published in August 2024, the USDA proposal seeks to classify raw poultry as adulterated if it contains 10 or more colony-forming units (CFU) of any salmonella strain or any detectable levels of specific high-risk serotypes. Additionally, the rule mandates regular USDA testing and requires slaughter facilities to adopt stricter contamination prevention measures.

The introduction of this bill coincided with the release of a Government Accountability Office (GAO) report, which highlighted that the USDA’s Food Safety and Inspection Service (FSIS) had put other microbial safety initiatives on hold to prioritize the salmonella framework. The GAO advised FSIS to establish a strategy for managing its food safety objectives more effectively.

Meanwhile, food recalls linked to bacterial contamination reached their highest level in five years, according to data from the FDA and USDA.

Revenue Management Software, AI, and Price Fixing Implications for Agriculture, By Todd Janzen

By

-

One of the ways that artificial intelligence (AI) has been marketed to agricultural business owners is as a tool to improve market competitiveness. AI platforms promise to deliver real time market insights in a way that humans never could, since AI has the ability to analyze much larger datasets than any single person. This post explores whether such market insight tools might actually lead to price fixing problems—illegal conduct under US law—rather than an increase in competitiveness.

What is illegal price fixing? Price fixing in the legal sense originates from the Sherman Antitrust Act of 1890. Under Section 1 of the Act, in order to demonstrate illegal price-fixing conduct, a plaintiff must demonstrate that an injury resulted from: “(1) the existence of a contract, combination, or conspiracy among two or more separate entities that (2) unreasonably restrains trade and (3) affects interstate or foreign commerce.” For the purposes of this post, let’s focus on two of those elements: First, there must be some “agreement” by sellers to fix prices. Second, that agreement must be with competitors. “Competitors” are those persons or entities engaged in similar lines of business, competition for sales with similar customers.

How might AI tools create price fixing? There are many AI tools on the market already that promise market insight from data collected from various competitors in the same market. While these competitors would not agree to share their market data directly with another competitor, as that could be viewed as an agreement to fix prices, these competitors might agree to anonymously share their market data with a third-party AI tool which then shares market intelligence with its users.

An example is already underway in the real estate rental market. Using different online platforms, landlords in various cities and markets all agree to share information about their rental spaces, such as rent, vacancies, operating costs, and other information reported to a central data exchange platform. The platform uses algorithms to provide insights to landlord users, advising them that, for example, their rent is lower than average in the market space. The result—the landlord knows it can raise rent and still be competitive in the market, and a tenant that might have found a lower rent now pays the market average instead of a better deal. Is this an agreement to fix rental prices?

Are such AI pricing tools legal? We are seeing litigation on these AI-influenced rental markets start to unfold in the courts. A recent case by the Justice Department and ten states against RealPage, Inc., an online platform offering landlord “revenue management” software, has claimed that such software and its use by landlords has resulted in illegal price fixing harming tenants. As alleged by the DOJ in its Amended Complaint against RealPage:

Renters are entitled to the benefits of vigorous competition among landlords. In prosperous times, that competition should limit rent hikes; in harder times, competition should bring down rent, making housing more affordable. RealPage has built a business out of frustrating the natural forces of competition. In its own words, “a rising tide raises all ships.” This is more than a marketing mantra. RealPage sells software to landlords that collects nonpublic information from competing landlords and uses that combined information to make pricing recommendations. In its own words, RealPage “helps curb [landlords’] instincts to respond to down-market conditions by either dramatically lowering price or by holding price when they are losing velocity and/or occupancy. . . . Our tool [] ensures that [landlords] are driving every possible opportunity to increase price even in the most downward trending or unexpected conditions” (emphases added).

In fact, as RealPage’s Vice President of Revenue Management Advisory Services described, “there is greater good in everybody succeeding versus essentially trying to compete against one another in a way that actually keeps the entire industry down” (emphasis added). As he put it, if enough landlords used RealPage’s software, they would “likely move in unison versus against each other” (emphasis added). To RealPage, the “greater good” is served by ensuring that otherwise competing landlords rob Americans of the fruits of competition—lower rental prices, better leasing terms, more concessions.

Courts are wrestling with whether such rent sharing constitutes illegal price fixing because AI data sharing tools lack the traditional “agreement” between competitors. Instead, the users of the platform set prices according to the information learned through using the tool. There is no requirement to follow the market information, but is there an implied agreement if users consistently implement the platform’s suggestions? Is that enough to constitute an agreement among competitors to fix prices? We will see this issue litigated in the next few years but the answer is not clear today.

Conclusion. The outcome of the rent-sharing cases will be important for AI developers and farmers. Agricultural goods and commodities are highly competitive. Farmland rental rates in particular are extremely competitive. Use of similar “revenue management” platforms in agriculture might be viewed as anti-competitive by farmers who are used to handshake deals with landlords that do not traditionally share their rental rates. What do you think the outcome of such cases should be?

Cargill and BinSentry introduce AI-powered tools to optimize Brazil’s animal feed supply chains and increase profits for pork and poultry producers

By
Sophi Fairman
-

Cargill and BinSentry have formalized a partnership to provide artificial intelligence (AI)-powered sensor technology to help Brazilian producers improve efficiency and control of their animal feed supply chain for healthier pork and poultry, and more profitable operations.

The agreement makes Cargill the exclusive distributor in Brazil of BinSentry’s animal feed inventory management platform. It builds on a partnership that began more than four years ago to market the companies’ leading-edge technology across North America to ensure producers, feed mills and their customers get the right feed at the right time, and in the right quantities, for their operations.

Integrating BinSentry technology with Cargill’s expertise in sustainable food production will open up exciting opportunities for the Brazilian agrifood sector, said Marcelo Dalmagro, Strategic Marketing and Technology Leader for Cargill Animal Nutrition in South America.

“Cargill, a global leader with over 150 years of history, is proud to team up with BinSentry, a growing ag-tech innovator, to bring cutting-edge technology to Brazil that will help producers optimize their operations, increase the competitiveness of Brazilian agribusinesses and strengthen Brazil’s position as a leading exporter of pork and poultry,” said Dalmagro.

BinSentry’s rugged, easy-to-install sensors are now monitoring more than 25,000 feed bins for some of the largest swine and poultry producers in the United States and Canada. The solar-powered, self-cleaning sensors monitor feed levels in bins with 99% accuracy. Combined with proprietary software that analyzes the sensor data and a mobile dashboard that works on any device, BinSentry allows producers to manage feed in real time, prevents costly out-of-feed events and eliminates the need for unreliable and dangerous manual inventory checks.

Combined with Cargill’s solutions in animal nutrition, logistics and analytics, the BinSentry platform turns data into actionable insights that enhance process control, reduce transportation costs, reduce waste and lower feed conversion ratios for increased profitability.

“Intelligent process automation is the new frontier in animal production,” said BinSentry CEO Ben Allen. “Animal feed represents 60% to 70% of total production costs, so both industry and producers benefit from advancements in precision feed monitoring, supply chain management and planning.”

While Brazil is known as a leading producer and exporter of livestock and poultry, its vast territory and diverse landscapes present significant production and management challenges. Partnering with BinSentry will help the industry overcome those challenges by boosting efficiency of the animal feed supply chain, said Dalmagro.

“We pride ourselves on deeply understanding producers and continually seeking solutions to their challenges. Now, in addition to Cargill’s high-performance nutrition and health products, we are bringing an AI-powered management tool to the Brazilian market that will help producers unlock savings and make data-based decisions that improve their operations and their bottom line,” Dalmagro said.

Domestic and Global Poultry Market and HPAI Outlooks Highlighted at the Poultry Market Intelligence Forum at IPPE 2025

“Two years from now, will people be happy with the agenda…or not happy?” asked Christian Richter, principal with The Policy Group, during his 2025 Washington update. He spoke at the Poultry Market Intelligence Forum, sponsored by the U.S. Poultry & Egg Association, and held during the 2025 International Production & Processing Expo (IPPE).

Richter was referring to the upcoming administration, mentioning that among the priorities will be border security and immigration, tariff policy, deregulation and defunding, and legislation. He also remarked that more worksite enforcement will be coming, especially in agriculture. In addition, Richter noted that the Clean Water Act Effluent Limitations Guidelines and Standards for PFAS Manufacturers Under the Organic Chemicals, Plastics and Synthetic Fibers Point Source Category proposed rule is pending until August 2025, as well as emissions modeling for animal agriculture.

Mark Jordan, executive director for LEAP Markets Analytics, provided an economic update. He stated that in the U.S., per capita availability of red meat and poultry is at a record high and climbing. He observed that supplies of animal protein per capita in the U.S. are growing, led by broilers.

Jordan also said that the animal health threat is higher than at any point in recent memory. He indicated that if highly pathogenic avian influenza does not slow down, table egg production could decrease considerably. He also remarked that disease (e.g., avian metapneumovirus) and demand issues have significantly impacted the turkey industry.

As part of her presentation on “Going the Distance: Engaging from Farm to Fork,” Wendy Reinhardt Kapsak, president and CEO of International Food Information Council, commented that more than 70% of Americans snack at least once a day and mentioned that “snacking may replace a meal, so this is a good opportunity for animal protein producers.” She also discussed the health benefits of food that are sought out by generation, with Gen Z, Millennials and Gen X looking for energy, while the Boomer generation seeks food for healthy aging.

Further, Reinhardt Kapsak observed that among the purchasing drivers and shopping patterns, taste is the top purchasing driver, followed by price. In addition, she commented that “healthcare professionals and registered dietitians are the most trusted sources for foods to eat and avoid.”

Control plan reveals poultry meat contamination rate in France

By
Sophi Fairman
-

Results of a French surveillance operation have been published, revealing the rate of contamination in fresh poultry meat at retail.

In France, Salmonella and Campylobacter are the two main bacterial agents responsible for foodborne infections, and Clostridioides difficile is often isolated from the stools of patients with digestive disorders. Poultry is recognized as a reservoir for these three pathogens.

An official surveillance plan organized by the Directorate General for Food (DGAL) in 2022 updated data on Salmonella and Campylobacter in poultry products with skin (thighs) and without skin (cutlets) at retail level and also collected related Clostridioides difficile data.

The prevalence of Salmonella, Campylobacter, and Clostridioides difficile was 0.9 percent of 2,435 units, 49.2 percent of 2,425 units and 0.9 percent of 465 units, respectively. For all pathogens, the prevalence was higher on products with skin.

For Campylobacter, a seasonal effect was observed, with the percentage of positives lower in winter than in the other three seasons.

Campylobacter and Salmonella findings
Campylobacter counts showed that 28 percent of the cutlets and 31 percent of the thighs were contaminated at levels below 10 colony forming units per gram (CFU/g). However, 2.4 percent of the thighs and 0.2 percent of cutlets had more than 1,000 CFU/g, which is the threshold for slaughterhouse hygiene criteria.

There is no regulatory limit in Europe for Campylobacter or Clostridioides difficile in fresh chicken meat at retail. There are rules around Salmonella Typhimurium and Salmonella Enteritidis in fresh poultry meat.

There is also hygiene criteria for Campylobacter involving testing neck skin samples of broiler chicken carcasses. Beginning in January 2025, no more than 10 samples out of 50 should exceed 1,000 CFU/g.

Levels of Campylobacter contamination appeared to have dropped compared to a similar control plan in 2009. Scientists said this could be because of the European regulation on Campylobacter testing at slaughterhouses.

From 2,425 units analyzed, 1,192 were positive for Campylobacter. Clostridioides difficile was only found in four of 465 samples.

Among Campylobacter positive units, 344 cutlets and 370 thighs were contaminated at under 10 CFU/g. A total of 187 thigh samples had more than 100 CFU/g and three were above 10,000 CFU/g. For cutlets, 22 were above 100 CFU/g.

Results revealed 23 Salmonella positives from 2,435 units. Seven different serotypes were found including Salmonella Infantis, Salmonella Agama, and Salmonella Derby. Campylobacter was also detected in 10 Salmonella-positive samples.

The prevalence of Salmonella in broiler chicken products had been estimated at retail at 1.7 percent in 2009 and 1.2 percent in 2010. This compares to 0.9 percent in the current survey.

Vaccinating for Marek’s disease? Don’t be thrown off by PFU levels

By
Sophi Fairman
-

As the use of recombinant or vector vaccines for poultry continue to grow around the world, misperceptions around a vaccine’s plaque-forming unit (PFU) level are leading to inaccurate conclusions about vaccine protection.

Plaques form when virus infects cells. Marek’s disease virus is able to spread to adjacent cells without killing them. However, this infection leads to changes in the morphology of the infected cells forming what is known as plaques. Counting plaques in cell culture is the gold standard method to establish Marek’s disease vaccine titers (plaque-forming units or PFUs).

Frequently, high PFU levels of herpesvirus of turkey (HVT) vaccines are inaccurately associated with greater protection; and worse, PFU levels are used to determine a vaccine’s possible dilution rate, said Isabel M. Gimeno, DVM, PhD, professor, North Carolina State University.

However, PFUs are not a measure of vaccine efficacy and there is no magic PFU number that guarantees protection. The number of PFUs necessary to achieve the greatest efficacy depends on the product, said Gimeno, an expert in vector vaccine research.

PFUs unique to each vaccine

The amount of PFUs per dose relates to how adapted the vaccine virus is to cell culture, Gimeno said. Even though all commercial HVT vaccines are derived from the FC-126 strain isolated by Witter,1 each vaccine manufacturer has its own seed virus and will do several passages to get to commercial levels. Depending on several factors – cell type use, days between passages, number of passages and culture media, among others – viruses adapt differently to grow in cell culture.

“The more adapted the virus is, the higher PFUs per dose can be obtained. On the other hand, better growth in cell culture might lead to less replication in vivo,” she said.

It is critical to follow the manufacturer’s recommended dosage for an HVT vaccine and not dilute it based on its PFU level. Any change in the recommended dose could result in subpar results, as shown in a 2016 study.2 In this study, different HVT products, including one conventional and three recombinant HVTs, were administered in ovo at 1,500 PFUs regardless of what the recommended dose was for those vaccines. Some vaccines performed better than others when reducing the dose to 1,500 PFUs.2

Alternatively, increasing the dose might not be good in some cases, she said. Adding a very high dose of a Marek’s disease vaccine such as CVI988 when mixing with a recombinant HVT (rHVT) was shown to result in reduced rHVT replication, which emphasizes the relevance of following manufacturer recommendations.3

PFU variability

Marek’s disease vaccines are cell associated, meaning that there is a mix of infected (5%-20%) and non-infected (80%-95%) cells in the vial instead of free infectious viral particles. Hence, they are extremely fragile (the virus dies if the cell dies) and there is great variability on the vaccine dose, Gimeno explained.

She pointed to a 2019 study that demonstrated the PFU dose-to-dose variability at the time of reconstitution in each vial is between 10% and 34%.4

“PFU ratings are averages. Don’t think that because a vaccine has a particular PFU that every single dose has this PFU level,” she said.

Over time, the number of PFUs per dose can get more variable. The moment a vaccine is reconstituted, it has the maximum number of PFUs, which start to drop off. Improper handling and mixing, as well as the use of antibiotics in combination with an HVT, can lead to very inconsistent PFU levels, Gimeno said. In some cases, chickens might not receive enough dosage to confer protection.

Getting the most from vector vaccines

Overall, rHVT vaccines have been shown to be as efficacious as conventional HVT vaccines with the advantage of providing immunity against other viral diseases, such as infectious bursal disease or Newcastle disease, Gimeno concluded. To get the most out of a vector vaccine program, the focus should be on vaccine handling, preparation and timely administration – factors under the control of poultry veterinarians.
