In the last 30 days, the U.S. Department of Agriculture (USDA) has confirmed highly pathogenic avian influenza (HPAI), or H5N1, in:
- 69 cases in poultry in 29 states.
- Two cases in livestock in two states.
Wisconsin and the National Milk Testing Strategy (NMTS)
To date, there has been one H5N1 detection in livestock other than poultry in Wisconsin. Access the list of recent poultry detections in Wisconsin and the list of livestock detections in Wisconsin.
With help from industry partners, Wisconsin is sampling milk at the farm level for the mandatory USDA Animal and Plant Health Inspection Service (APHIS) NMTS. When Wisconsin began NMTS testing in May 2025, the goal was to test each farm approximately every month. Wisconsin achieved unaffected Gold Status under the NMTS in September 2025. In October, DATCP reduced its testing frequency to 50%.
Wisconsin will resume NMTS testing at a 100% frequency statewide. DATCP will continue to utilize milk samples that are already collected through existing, routine sampling to streamline the NMTS testing process. The DATCP HPAI in Dairy Cattle webpage will continue to be updated weekly as the testing continues.
