HPAI Confirmed in Commercial Poultry Flock in Barron County

On September 14, highly pathogenic avian influenza (HPAI) was confirmed in a commercial poultry flock in Barron County. Access the press release. Find information on biosecurity to protect your farm from infectious diseases.

The Wisconsin Department of Health Services (DHS) and Barron County Public Health are monitoring exposed farm workers for HPAI symptoms. The risk to the general public in Wisconsin remains low. Find information related to prevention information for farmworkers or others who have close contact with birds, dairy cows, or other relevant animals.

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.

When HPAI is diagnosed in a Wisconsin poultry flock, a control area is established within a 10-kilometer area around the infected premises, restricting movement on or off any premises with poultry. Poultry producers should utilize DATCP's mapping tool to determine if their poultry are located within an active control area or surveillance zone.
