MADISON, Wis. – The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) announces a confirmed case of highly pathogenic avian influenza (HPAI) in a poultry flock in Racine County.

Samples were tested by the Wisconsin Veterinary Diagnostic Laboratory and confirmed by the National Veterinary Services Laboratories. DATCP and the U.S. Department of Agriculture (USDA) continue working with animal health officials on a joint incident response. Birds on the property have been depopulated to prevent spread of the disease.

Three Wisconsin counties – Jefferson, Rock, and Racine – have now been confirmed with HPAI among domestic birds. Last month, the Wisconsin Department of Natural Resources (DNR) announced that five counties – Dane, Columbia, Grant, Milwaukee, and Polk – were confirmed with HPAI among the wild bird population. Poultry owners are asked to continue using strong biosecurity practices and, when possible, move their birds indoors.

DATCP also encourages poultry owners to register their premises. State law requires that all livestock owners register where their animals are kept, and registration helps animal health officials during disease outbreaks.

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 (business hours) or (800) 943-0003 (after hours and weekends).
