To date, there has been one H5N1 detection in livestock other than poultry in Wisconsin.
Biosecurity and Monitoring
It is important to remain vigilant and utilize enhanced biosecurity measures.
- Enhance biosecurity measures and monitor disease in your herds and flocks.
- Report flocks and herds with unexplained symptoms immediately.
- Report sick, dead, or injured wildlife to the Wisconsin Department of Natural Resources
- April 24, 2024 Federal Order: Lactating dairy cattle must test negative for Influenza A virus at a National Animal Health Laboratory Network (NAHLN) lab before interstate movement.
- Wisconsin Cattle Testing Order: Lactating dairy cattle must test negative for Influenza A virus before moving to fairs or exhibitions.
H5N1 Protocol: What to Do if H5N1 is Confirmed on Your Dairy Farm
DATCP created a resource document in case of a detection of H5N1 on a dairy farm. The document is intended to serve as a general reference for industry, but individual needs and response actions may differ for H5N1 detections depending on the operation and specific circumstances.
