H5N1 Detections In U.S. Livestock 2024
H5N1 in Livestock
Detections of Influenza A (H5N1) also known as Highly Pathogenic Avian Influenza (HPAI) in cattle and goats in the USA have prompted the Ontario Animal Health Network to provide this collection of resources for Ontario veterinarians and producers.
What to do if you observe livestock animals mammals with abnormal clinical signs consistent with HPAI infection:
- Producers should report clinical signs or suspected illness in their herds to their veterinarian immediately.
- Veterinarians should contact their local CFIA animal health office if there is a high degree of suspicion of HPAI.
What to do if you find sick or dead birds or other wildlife on your property:
- Report these findings to the Canadian Wildlife Health Cooperative (CWHC) who may arrange for submission of wildlife for HPAI testing at the University of Guelph’s Animal Health Lab (AHL).
