Highly pathogenic avian influenza (HPAI) was detected in a Benton County dairy herd on Thursday, marking Minnesota’s first case. BAH spokesperson Michael Crusan emphasized the importance of testing for farmers to help prevent future outbreaks. 

“If your animals show clinical signs or don’t look well, there is something not right. Have that conversation with your veterinarian as soon as possible and consider testing those animals,” Crusan advised. 

He added that sick cows must be isolated from the healthy herd for 30 days, cannot be moved off-site, and any milk produced must be treated and discarded. After the isolation period, the cows can be retested and, if healthy, reintegrated into the herd.
