The Department of Agriculture, Trade and Consumer Protection has identified a case of highly pathogenic avian influenza in a commercial poultry flock in Barron County. In a media briefing, DATCP confirmed it was a turkey flock.
The affected premises will not move birds or products, and it will depopulate the birds to prevent the spread of the disease. Birds from the flock will not enter the food system.
This is the first HPAI case in Wisconsin in any species since January.
The H5N1 HPAI virus has continued to circulate in both wild and domestic birds in North America since December 2021. H5N1 HPAI viruses are highly contagious and often fatal to domestic poultry. Caused by influenza type A viruses, the disease varies in severity depending on the strain and species affected. The disease spreads through contact with infected birds, commingling with wild birds or their droppings, equipment, or clothing worn by anyone working with the animals.
DATCP continues to urge 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. When possible, keep birds indoors.
When HPAI H5N1 infects a Wisconsin poultry flock, DATCP establishes a control area within a 10-kilometer area around the infected premises. The department restricts movement on or off any premises with poultry. State Veterinarian Darlene Konkle says there are no cattle operations within the control area, but there are other poultry producers.
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).
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.
