JEFFERSON COUNTY, Wis. – The state Department of Agriculture, Trade and Consumer Protection (DATCP) has announced a confirmed case of highly pathogenic avian influenza (HPAI) in a commercial poultry flock in Jefferson County.

This is Wisconsin’s first confirmed case of HPAI since 2015. DATCP and the U.S. Department of Agriculture (USDA) are working closely with animal health officials on a joint incident response.

The affected premises will not move poultry products, and birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system.

Producers are encouraged to move their birds indoors when possible to prevent contact with wild birds and their droppings.

HPAI viruses are a form of avian influenza that has been found to be highly contagious and often fatal to domestic poultry.

It can be spread by contact with infected birds, equipment, or clothing worn by those working with the animals.

Signs of HPAI in infected birds include:

  • Sudden death without clinical signs

  • Lack of energy or appetite

  • Decrease in egg production; soft, misshapen eggs

  • Purple discoloration of wattles, comb, and legs

  • Difficulty breathing

  • Runny nose, coughing, sneezing

  • Stumbling or falling down

  • Diarrhea

To report increased mortality or signs of illness among domestic birds, contact DATCP at 608-224- 4872 (during business hours) or 800-943-0003 (afterhours and weekends).
