The U.S. Department of Agriculture Animal and Plant Health Inspection Service has confirmed the detection of highly pathogenic avian influenza (HPAI) in a dairy herd in New Mexico, as well as 5 additional dairy herds in Texas. APHIS shared on March 29 that its National Veterinary Services Laboratories in Ames, Iowa, was working to confirm presumptive positive test results from New Mexico, Texas and Idaho herds; this announcement is a follow-up to that information.
This marks the first known case of HPAI in cattle in New Mexico and adds to the two detections in Texas that were first announced on March 25. To date, USDA has confirmed the detection of HPAI in dairy herds in Texas (7), Kansas (2), Michigan (1) and New Mexico (1). The presumptive positive test results for the Idaho herd are still pending analysis at NVSL.
