Last week, the USDA Animal and Plant Health Inspection Service (APHIS) confirmed HPAI H5N1 in a Minnesota commercial layer flock, where 940,000 hens were housed. This was the first commercial layer detection in 320 days since striking a Colorado farm on Dec. 20, 2022. In addition to the Minnesota case, APHIS posted a commercial turkey detection in South Dakota, WOAH Poultry in Iowa, and a commercial broiler breeder flock in Missouri.
The below chart depicts information pulled from APHIS on Nov. 8, 2023.
Producers across the country should proactively assume the virus is present in their areas and move biosecurity to the highest level. Continue to monitor the implementation of biosecurity programs and take additional precautions and delay activities when conducting high-risk activities such as moving birds or manure as fall migration persists.
