Highly Pathogenic Avian Influenza (HPAI)
On March 25, 2024, a mystery illness that had been impacting dairy herds in the Texas Panhandle, New Mexico and Kansas was officially diagnosed as Highly Pathogenic Avian Influenza (HPAI). Also known as bird flu, the same strain has been affecting the U.S. poultry flock for the past two years. The Dairy Herd team is tracking the HPAI cases to keep you aware of any changes while providing information you can use to elevate your knowledge and what the evolving dynamics could mean to your operation.
Researchers detected infectious H5N1 virus in milking parlor air and wastewater systems while also identifying possible subclinical infections in cattle.
