HPAI H5N1 Virus in Dairy Cattle – What We Know

In March 2024, Highly Pathogenic Avian Influenza (HPAI) A (H5N1), commonly referred to as bird flu, was confirmed in domestic U.S. livestock for the first time in a dairy operation in Texas. Since then, the virus has spread to 172 dairy operations across 13 states, raising widespread uncertainty throughout the dairy and livestock markets. Industry participants have raised concerns about the outbreak's potential impact on consumer perception and demand for dairy and meat products, though government agencies reiterate that the national food supply remains safe. Expana is closely monitoring the...

Penn State Tests Dairy Herd for Bird Flu in Support of State Surveillance Effort

Animal health experts in Penn State’s College of Agricultural Sciences have announced that — out of an abundance of caution — they will test the University’s dairy herd for highly pathogenic avian influenza, or HPAI, under a voluntary state testing program.

The announcement comes amidst an outbreak of bird flu that has affected dairy cattle in more than a dozen states since March. As of July 19, the virus had not been found in Pennsylvania dairy herds, according to the U.S. Department of Agriculture and state animal...

Regardless of species, biosecurity remains the best tool available to combat HPAI. On May 1, 2024, Director Boring issued the Determination of Extraordinary Emergency HPAI Risk Reduction...

Herbruck's Poultry Ranch Laying Off About 400 Staff in Michigan Due to Bird Flu

Herbruck's Poultry Ranch is temporarily laying off about 400 employees in Michigan due to the spread of bird flu.

The company's chief human resources officer Stephanie Kempa said the virus impacted the company's hen population at some farms in Ionia County.

"The company plans to rehire many positions as hen replenishing and egg production increases," Kempa said in a letter to the state Department of Labor and Economic Opportunity.

ANALYSIS: Checking-In on Turkey Market Supply Factors

Although mid-May trade conditions have been slow to shift the undertone surrounding whole-body turkeys and raw materials, there is no shortage of variables which are weighing heavily on the minds of market participants as they refine their expectations for the road ahead. Central to many turkey-related conversations remains disease.

As illustrated by this week’s chart, year-to-date (YTD) commercial HPAI outbreaks have risen about 84%, or 229.6 thousand head, when compared to a similar period one year prior...

INSIGHT: Experts Challenge Allegations of Poultry Litter in Feed Spreading HPAI in Cattle

In the weeks since the unprecedented discovery of US cattle testing positive for highly pathogenic avian influenza (HPAI), some mainstream media outlets have attempted to connect this to the use of poultry litter in cattle feed.

However, those familiar with the science and with the workings of the US livestock and poultry industry find the idea rests on shaky grounds.

Experts believe cattle infected by wild birds

In a document published on 26 April, the US Animal and Plant Health Inspection Service (APHIS) stated “The genetic and epidemiological data indicate spillover of the virus from...

Bird flu Outbreak in Dairy Cows Fails to Deter US Raw Milk Sellers

U.S. sellers of raw milk appear undeterred by federal health warnings for consumers to avoid drinking unpasteurized milk in light of a bird flu outbreak that has affected dairy herds in nine states and sickened at least one dairy farm worker.

Thirty of the 50 U.S. states permit the sale of raw milk, which accounts for less than 1% percent of U.S. milk sales. A nationwide survey of pasteurized milk - heated to kill pathogens - found avian flu virus particles in about 20% of samples tested...

USDA Confirms Detection of Avian Influenza in Dairy Cattle in Colorado

Yesterday, the US Department of Agriculture’s (USDA) National Veterinary Services Laboratory (NVSL) confirmed a detection of Highly Pathogenic Avian Influenza (HPAI) H5N1 in dairy cows in Northeast Colorado. This is the first detection of avian influenza diagnosed in cattle in Colorado. Detections of HPAI in dairy cattle have occurred in eight other states.

On Monday, April 22, the Colorado State Veterinarian’s office received a notification of a dairy herd demonstrating clinical signs consistent with HPAI in cattle. Samples submitted to the Colorado State University Veterinary Diagnostic Laboratory tested presumptive positive for HPAI on April 24, and were confirmed by the USDA's National Veterinary Services Laboratory on April 25.

INTERVIEW: Six Months On, France’s World-First HPAI Vax Campaign Seen as Successful

Early April marked six months since French authorities, along with the country’s poultry sector, embarked on an ambitious effort to vaccinate every commercially-raised duck on the mainland against highly pathogenic avian influenza (HPAI). The decision made it a global pioneer; although HPAI vaccines had been used in non-exporting countries to protect food security, no major exporter has done so, and the world has been closely watching the experiment. As an industry representative told Feedinfo last year, “We’re a bit like the guinea...

Properly Prepared Beef Remains Safe; Meat Institute Calls For Guidance to Protect Workers 

As the U.S. Department of Agriculture (USDA) issued a nationwide order including requiring lactating dairy cows to test negative for Highly Pathogenic Avian Influenza (HPAI) before interstate transport, the Meat Institute today said that properly prepared beef remains safe to eat and called for USDA and the Centers for Disease Control and Prevention (CDC) to provide worker safety guidance specific to beef processors to ensure workers are protected from infection.

“USDA and CDC are working overtime to understand the spread of the virus...

USDA Issues FAQ on Federal Order Requiring Bird Flu Testing in Dairy Cattle

On Wednesday, the U.S. Department of Agriculture (USDA) announced a Federal Order requiring mandatory testing of lactating dairy cattle for bird flu before interstate movement. Effective Monday, April 29, 2024, the order also mandates reporting positive influenza A test results in livestock to USDA’s Animal & Plant Health Inspection Service (APHIS). 

Highly pathogenic avian influenza (HPAI) causes less severe illness in cattle than in poultry, in which the virus is typically fatal, but remains a concern for livestock and humans who come into contact with infected animals...

ANALYSIS: Tightening Turkey Production Trends

Given the relatively serene state of the turkey market here in early Q2, market participants are keeping their eyes trained on the stats as they refine their expectations for the road ahead. When it comes to supply-facing variables, disease remains a top consideration, and with good reason. In just the first four months of the year, about 346 thousand commercial turkeys have been impacted by HPAI. Although this figure represents only a small fraction of the industry’s annual production potential, it is one part of a more complex scenario currently unfolding on the supply...

Cow-to-Cow Transmission Confirmed as a Factor in Spread of H5N1

In an update provided by the USDA, the agency confirmed that cow-to-cow transmission is a factor in the spread of H5N1 bird flu in dairy herds.

However, it remains unclear exactly how the virus is being moved around. “We know that the virus is shed in milk at high concentrations; therefore, anything that comes in contact with unpasteurized milk, spilled milk, etc. may spread the virus,” explained the USDA.

The government stressed the importance of biosecurity, including the movement of people, animals, vehicles, and...

States with HPAI-Infected Dairy Cows Grows to Six

A herd of dairy cattle in Ohio has been infected with highly pathogenic avian influenza (HPAI), increasing the number of states with dairy operations affected by the virus to six.

The USDA previously confirmed the H5N1 strain of HPAI in dairy cattle on seven Texas farms, two in Kansas, and one each...

ANALYSIS: Exploring Factors Influencing the Turkey Market

Although market-swaying spot trade activity is off to a fairly uneventful start in April, there are no shortage of variables that are lingering on the minds of turkey market participants as we proceed into spring. At the top of the "figurative" list is HPAI, which has been slow to relinquish its grasp on the poultry (and egg) industry. Through the first three months of the year, commercial HPAI turkey cases advanced by about 50%, or 70 thousand birds, from the year prior...
