The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) this week noted several commercial poultry outbreaks of avian flu, including an event in Kent County, Delaware, involving 147,900 birds that were part of a commercial broiler operation.
Walker County, Georgia had the second-largest detection this week, affecting 71,300 birds at a commercial broiler breeder facility.
Also recorded was an outbreak among 9,000 commercial turkey breeder hens in Meeker County, Minnesota. Smaller detections were noted in Colorado, Kansas, and Oregon.
In the past 40 days, APHIS reported 70 flocks with confirmed highly pathogenic avian influenza (HPAI), including 17 commercial flocks and 53 backyard flocks. A total of 1.17 million birds have been affected. Since the outbreak began in February 2022, more than 185 million birds and 2,022 flocks have been affected, 917 of which have been commercial poultry flocks.
Dozens of detections in ducks across the country
In wild birds, APHIS this week recorded 80 detections from across the country, suggesting HPAI is widespread among waterfowl, as more than 60 of the detections were in wild and hunter-harvested mallards.
Dozens of ducks in York County, Maine, were found to have HPAI, along with geese in Douglas County, Nebraska, and a bald eagle in Hernando, Florida.
