The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has identified cases of highly pathogenic avian influenza (HPAI) in backyard flocks in Pierce and Sauk counties. Birds on both sites will be depopulated to prevent spread of the disease.
Eleven counties in Wisconsin have been confirmed with HPAI in domestic flocks. Flock owners are encouraged to continue practicing strong biosecurity measures to protect their birds from the virus. This includes washing hands, disinfecting equipment, restricting access to birds, and separating new birds from existing flocks for at least 30 days. Poultry owners are asked, when possible, to keep 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 communicate with flock owners during disease outbreaks.
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). Signs of HPAI 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
