Highly Pathogenic Avian Influenza Strain spreading mystery Illness in cows in Texas
A mystery illness that's impacted dairy herds in the Texas Panhandle, New Mexico and Kansas now has a diagnosis: Influenza A. USDA says genetic sequencing revealed it's the same strain of Highly Pathogenic Avian Influenza (HPAI) that's been in the U.S. for two years.
APHIS says the "National Veterinary Services Laboratories" detected Influenza "A" in samples from several impacted herds in Texas, Kansas and New Mexico. The virus is carried by wild waterfowl, which experts think is how the illness is spreading. Even with the diagnosis, USDA is still not recommending movement restrictions of animals.
According to the Texas Department of Agriculture, Texas Agriculture Commissioner Sid Miller received confirmation from the United States Secretary of Agriculture, Tom Vilsack, and the Animal and Plant Health Inspection Service (APHIS) that the mystery disease has been identified as a strain of Highly Pathogenic Avian Influenza (HPAI) commonly known as Bird Flu. To date, three dairies in Texas and one in Kansas have tested positive for HPAI.
USDA reports that affected dairy cows do not appear to be transmitting the virus to other cattle within the same herd. APHIS says based on findings from Texas, "the detections appear to have been introduced by wild birds. Initial testing by the National Veterinary Services Laboratories has not found changes to the virus that would make it more transmissible to humans, which would indicate that the current risk to the public remains low."
APHIS also says federal and state agencies are moving quickly to conduct additional testing for HPAI, as well as viral genome sequencing, to better understand the situation, including characterization of the HPAI strain or strains associated with these detections.
The Texas Department of Agriculture (TDA) also says they are "vigilantly monitoring this outbreak."
“This presents yet another hurdle for our agriculture sector in the Texas Panhandle,” Miller said in a statement. “Protecting Texas producers and the safety of our food supply chain is my top priority. The Texas Department of Agriculture will use every resource available to maintain the high standards of quality and safety that define Texas agriculture.”

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,” Miller added. “Cattle are expected to fully recover. The Texas Department of Agriculture is committed to providing unwavering support to our dairy industry.”
As AgWeb and AgDay first reported last week, dairy farmers in the Texas Panhandle, NewMexico and Kansas were dealing with quite the mystery. Something is causing milk production to nosedive, and veterinarians and state officials can’t pinpoint what it is. In affected cowherds, the issue impacts nearly 10% of the animals, causing reduced feed consumption and a 10% to 20% decline in milk production.
