JEFFERSON COUNTY, Wis. (WFRV) – Wisconsin Officials confirmed its first case of highly pathogenic avian influenza since 2015, and the flock will not enter the food system.

According to the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), a confirmed case of highly pathogenic avian influenza (HPAI) was found in Jefferson County. The case was in a commercial poultry flock.

Samples were reportedly tested by the Wisconsin Veterinary Diagnostic Laboratory and were confirmed by the National Veterinary Services Laboratories in Iowa.

This is the state’s first confirmed case of HPAI since 2015. Officials are reportedly working on a joint incident response. The area that is affected will reportedly not move poultry products. Birds on the property will be depopulated to prevent the spread of the disease.

The U.S. Centers for Disease Control and Prevention says that HPAI does not present an immediate public health concern. No human cases of avian influenza have been found in the U.S.

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

HPAI does not pose a food safety risk, as cooking poultry and eggs to an internal temperature of 165 degrees kills the virus.

Additionally, DATCP has issued a special order immediately banning poultry from any movement to, or participation in, shows, exhibitions, and swap meets held in Jefferson County. The order will remain in effect through May 31, 2022.
