Avian Influenza Detected in Dairy Cattle

On Monday, March 25th the US Department of Agriculture (USDA), Food and Drug Administration (FDA), and Center for Disease Control (CDC) issued a statement confirming the identification of Highly Pathogenic Avian Influenza (HPAI) in dairy cattle located in Texas and Kansas. They have suspected that HPAI may be a contributing factor in the unclassified illness affecting older, mid to late lactation dairy cattle in several herds in New Mexico, Texas, and Kansas over the past two months. It is not yet clear if all reports of the unclassified illness are caused by HPAI. The full press release from USDA can be found here. The OSU Extension Vet Med team worked on a factsheet attached here. The following are answers to common questions producers and the general public may have about this outbreak.
