Minnesota reported its first highly pathogenic avian flu outbreaks, affecting flocks in three counties, as three more states—Colorado, North Dakota, and Pennsylvania—reported their first detections in waterfowl.

Also, four earlier affected states reported more outbreaks in poultry, part of activity involving the Eurasian H5N1 strain. The development in Minnesota lifts the number of states reporting poultry outbreaks in 2022 to 18. So far, the outbreaks have led to the loss of about 14.4 million birds.
