Cows at Two Texas Dairy Farms Have Bird Flu, Another Blow to Cattle Country Following Wildfires

BY JAYME LOZANO CARVER

Cows in the Texas Panhandle have tested positive for the bird flu, another blow to the Texas dairy industry following historic wildfires that killed at least 7,000 livestock.

The discovery, reported at two different dairies, is believed to be the first time the disease was found in livestock, researchers say.

Strains of Highly Pathogenic Avian Influenza, commonly known as the bird flu, were confirmed Monday by the U.S. Secretary of Agriculture and the Animal and Plant Health Inspection Service. The state agriculture department is also monitoring the outbreak. Similar outbreaks have been reported at dairies in Kansas and New Mexico.

The U.S. Department of Agriculture said 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.

“In the rare event that some affected milk enters the food chain, the pasteurization process will kill the virus,” said Texas Agriculture Commissioner Sid Miller.

The dairy industry is critical for the state. With about 292 dairies and an estimated 625,000 cows, Texas ranks fourth in the U.S. when it comes to milk production, and contributes roughly $50 billion to the state’s economy. In the Panhandle, also known as Cattle Country, more than 1.3 billion gallons of milk are produced each year, according to data from the Texas Association of Dairymen. The highest rates of production are in Hartley, Castro and Moore counties.

According to the Texas Animal Health Commission, the disease is causing a decrease in milk production as well as thicker, colostrum-like milk and cows have less of an appetite. The disease is also severely impacting older cows and cows in mid-lactation. Infected herds are expected to lose up to 40% of their milk production for 7-10 days until they recover from their symptoms, Miller said.

On average, about 10% of each affected herd appears to be infected. The USDA did not specify if any cows have died from the disease. And experts say it can be difficult to track as dairies are also culling cattle for other reasons.

Milk loss from infected cows is “too limited” to have a major impact on supply.

“There should be no impact on the price of milk or other dairy products,” the USDA said in a statement.

Multiple agencies are working fast to monitor the affected herds and conduct additional testing. The disease moves quickly from bird to bird, but experts say the disease is uncommon for dairy herds.

“We have never seen avian influenza in dairy cows before,” said Erin Supak, director of communications for the animal health commission. “So we’re encouraging best management practices and enhanced biosecurity measures to be put in place and ensure the spread is not going to go farther than it already has.”

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Anna Johnson from Iowa State University and Emma Coursey from the University of Illinois discuss research evaluating welfare resources during the late finishing stage on commercial swine farms. They explain how feeder management, water use, space allocation, and pig health influence welfare outcomes and practical on-farm management. Listen now on all major platforms!

"Small resource issues can become larger welfare problems when multiple stressors interact across finishing barns."
