Jefferson County

The following is an update on Highly Pathogenic Avian Influenza (HPAI) caused by the influenza virus H5N1.  

On October 1, HPAI H5N1 was confirmed in a commercial poultry flock in Jefferson County. Access the press release. Find information on biosecurity to protect your farm from infectious diseases.

There have been no detections of HPAI H5N1 in Wisconsin cattle.

DATCP and the Wisconsin Department of Health Services (DHS) continue to work together to provide information on personal protective equipment (PPE). DHS advises those working with animals to take precautions and wear PPE per CDC guidance. According to the Centers for Disease Control and Prevention (CDC), the public health risk from H5N1 detections remains low. 

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 H5N1 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.
