More dairy cattle in Idaho, New Mexico, and Texas have tested positive for highly pathogenic avian influenza virus (HPAI).
The U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) announced April 1 and 2 that these mark the first known cases of HPAI in cattle in Idaho and New Mexico, and add to the two detections in Texas and two in Kansas that were announced on March 25.
To date, the USDA has confirmed the detection of HPAI in seven dairy herds in Texas, two in Kansas, and one each in Idaho, Michigan, and New Mexico. The National Veterinary Services Laboratories (NVSL) is currently performing confirmatory tests on presumptive positive results from Kansas, New Mexico, Ohio, and Texas. While these samples are from cattle with at least some clinical signs in common with other cattle diagnosed with HPAI, the USDA says the presence of HPAI should not be considered confirmed until the NVSL analysis is complete.
