Headline:  WATT Poultry, 10/23/2026

Roy Graber reports:

For the second time in less than a week, the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) reported that highly pathogenic avian influenza (HPAI) has been detected in a commercial poultry flock in Barron County.

The latest flock infection was announced in a press release that was issued on Oct. 22. The earlier HPAI case was announced on Oct. 19. 

DATCP stated that its animal health officials were working with the U.S. Department of Agriculture (USDA) in a joint incident response regarding both flocks. The affected premises were quarantined to restrict movement of poultry and poultry products. Birds on the property were depopulated to prevent the spread of the disease. 

DATCP has not offered more specific information concerning the type of commercial poultry involved, or how many birds were in either of the flocks
