Highly Pathogenic Avian Influenza Found in Dodge County Dairy Herd
The case was identified through routine milk testing, marking the first detection in Wisconsin dairy cattle amid regional poultry infections, state officials said.
- On Dec. 14, 2025, the Wisconsin Department of Agriculture, Trade and Consumer Protection reported bird flu in a Dodge County dairy herd, the state's first dairy-cattle case, and quarantined the affected farm.
- Routine National Milk Testing Strategy screening found a Dodge County dairy herd tested positive for HPAI, with nearby detections in Marquette County on Dec. 9 and poultry farms in Jefferson County; several states reported cases this year.
- Officials advised livestock owners and poultry owners to register premises and report illness via the DATCP Animal Disease Reporting webpage; signs include reduced feed intake and decreased rumen motility, while CDC said human health risk is low and USDA confirmed pasteurization protects milk.
- State law requires livestock owners to register where animals are kept, aiding animal health officials during outbreaks as bird flu can reduce milk production and appetite in cattle.
- Multiple states reporting dairy-cattle cases this year and routine milk testing highlight ongoing surveillance and spread, ADM Investor Services and U.S. Department of Agriculture said Sunday.
