HPAI Information and Resources for Wisconsin Dairy Farmers


We ask that you not share unverified information to ensure harmful or misinformation is not shared. Producers are strongly encouraged to contact their veterinarian about any animal health concern to help learn more about Highly Pathogenic Avian Influenza (HPAI).

There are currently no known cases of HPAI in Wisconsin. We are closely monitoring the situation and will update this page as new information is released.


USDA announced several actions to protect livestock health against the spread of Highly Pathogenic Avian Influenza (HPAI) in dairy cattle as well as other livestock populations. This includes a Federal Order requiring the following measures, effective Monday, April 29. view more...

The FDA and others reaffirm that the commercial milk supply is safe. The FDA published an update indicating preliminary results of egg inoculation tests on PCR-positive retail milk samples shows that pasteurization is effective in inactivating HPAI. This additional testing did not detect any live, infectious virus.

Producers who believe dairy cattle within their herd are showing clinical signs should report them immediately to their veterinarian and/or state veterinarians. If your veterinarian suspects the disease, the samples they take and submit will have no lab fees. Animals may also be reported to APHIS' toll-free number at 1-866-536-7593

We will continue to provide updates on relevant information as it becomes available. If you have any questions, please contact Tina Peterson at 608-203-7210.
