DATCP and the U.S. Department of Agriculture (USDA) animal health officials are working together in a joint incident response. The affected premises has been quarantined to restrict movement of poultry and poultry products. Birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system.

The Wisconsin Department of Health Services (DHS) and Jefferson County Public Health are monitoring exposed farm workers for HPAI symptoms. The risk to the general public in Wisconsin remains low. Prevention information for farmworkers or others who have close contact with birds, dairy cows, or other relevant animals can be found under https://www.dhs.wisconsin.gov/occupational-health/farm-health.htm.

DATCP urges all livestock owners to implement strong biosecurity measures to protect their flocks and herds from the disease. This includes washing hands, disinfecting equipment, restricting access to animals, and separating new additions to the flock or herd for at least 30 days. Poultry owners are asked, when possible, to keep their birds indoors.
