Highly pathogenic avian influenza identified in Barron county flock

Another case of highly pathogenic avian influenza (HPAI) has been identified in Wisconsin, this time in a commercial poultry flock in Barron County. This is the state’s fourth detection of HPAI among domestic flocks.

The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) confirmed the case of HPAI. Animal health officials, DATCP, and the U.S. Department of Agriculture (USDA) are working on a joint response. To prevent the spread of the disease, birds on the property will be depopulated.

DATCP issued an order on April 7 immediately suspending poultry shows and exhibits through May 31, 2022 as efforts are being made to prevent the spread of HPAI. Poultry owners are asked to continue to use strong biosecurity practices and move their birds indoors if possible.

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 increase mortality of signs of illness among domestic birds, contact DATCP at (608) 224-4872 during business hours or (800) 943-0003 after hours or on weekends.
