Nevada Department of Agriculture taking additional action to prevent the spread of avian influenza

The Nevada Department of Agriculture (NDA) in conjunction with the U.S. Department of Agriculture (USDA) Wildlife Services is taking additional action in an effort to prevent the spread of avian influenza. Dairy cattle premises in Nye and Churchill Counties have been placed under quarantine due to detections of Highly Pathogenic Avian Influenza (HPAI). The USDA National Veterinary Services Laboratory is continuing testing to confirm what strain of virus has been detected in Churchill County. Preliminary results show this detection to be consistent with a strain that has also been detected in wild birds in all North American flyways.

This is a huge paradigm shift in H5N1 in dairy - more to come, I’m sure…
