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. To help producers determine if their poultry are located within an active control area or surveillance zone, poultry owners are encouraged to use DATCP's mapping tool.
The Wisconsin Department of Health Services (DHS) and county public health entities 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 Protective Actions for People. Farm workers, businesses, and processors can request a limited supply of surplus personal protective equipment (PPE) through the Wisconsin DHS Office of Preparedness and Emergency Health Care. For more information, visit Office of Preparedness and Emergency Health Care: https://www.dhs.wisconsin.gov/preparedness/medical-stockpile.htm.
DATCP reminds Wisconsin livestock owners to register their premises. State law requires that all livestock owners register where their animals are kept. Registration helps animal health officials communicate with flock and herd owners during disease outbreaks.
To report increased mortality or signs of illness among domestic birds, dairy cattle, or other animals, contact DATCP at (608) 224-4872 (business hours) or (800) 943-0003 (after hours and weekends). For updates on how the virus is affecting domestic birds in Wisconsin, and to find resources on protecting Wisconsin poultry, visit DATCP's HPAI in Poultry webpage: https://datcp.wi.gov/Pages/Programs_Services/HPAIWisconsin.aspx.
H5N1 in Other Species
The HPAI H5N1 virus has continued to circulate in both wild and domestic birds in North America since December 2021. Since that time, the H5N1 virus has also affected other species, including mammalian species. A specific genotype of H5N1 virus was first detected in dairy cattle earlier this year in Texas. To date, Wisconsin has not identified an H5N1 infection in dairy herds in the state. DATCP continues to work with USDA to conduct testing for H5N1, encourage biosecurity, and provide resources to producers.
