Highly Pathogenic Avian Influenza Update

HPAI Banner

Highly pathogenic avian influenza (HPAI) continues to threaten poultry, dairy cattle, and other animals. States surrounding Wisconsin continue to report new cases in poultry. Access the U.S. Department of Agriculture (USDA) list of cases.

The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) encourages poultry owners to protect their flock by practicing strong biosecurity.

State law requires Wisconsin backyard and commercial poultry owners, as well as other livestock owners, to register where their animals are kept. DATCP uses this information to rapidly respond to animal disease outbreaks to protect animal health, the food supply, public safety, and Wisconsin's agriculture economy. Registration is free and can be completed at wiid.org or by calling the Wisconsin Livestock Identification Consortium at (888) 808-1910. 

As a reminder, HPAI—highly contagious and often fatal to domestic poultry—can be spread by commingling with wild birds or their droppings and through contact with infected birds, equipment, or clothing worn by anyone working with infected animals.  

The following are signs of HPAI infection in birds:

• 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

Be sure to monitor flocks for any changes in behavior and call (608) 224-4872 or email DATCPanimalimports@wisconsin.gov to report any birds that may appear sick or that have recently died.

DATCP will continue to update the HPAI in Wisconsin webpage with new resources and information about the impact of the virus among commercial and backyard flocks.
