The Oklahoma Department of Agriculture, Food and Forestry (ODAFF) announced that the presence of highly pathogenic avian influenza (HPAI) was confirmed on November 30 in a commercial poultry flock in Adair County.
ODAFF posted a notification concerning the flock infection on its website, but did not offer any further details on the matter. Also, no information on this situation has yet been shared by the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), which has been tracking the flock infections throughout the 2022-24 North American HPAI outbreak.
However, ODAFF spokesman Lee Benson told KGOU it was a flock of about 64,000 broiler breeders, and control measures such as quarantine, zoning, surveillance and movement restrictions are in place.
According to APHIS, the only instance of HPAI to be reported in birds in the state in 2024 was a non-commercial case, confirmed on November 21. The only other time the presence of HPAI was confirmed commercial poultry in Oklahoma during the past three years was in April 2022, with that infection involving a flock of 13,800 commercial broiler breeders in Sequoyah County.
Sequoya County borders Adair County to the south.
In July, ODAFF announced that the presence of the H5N1 virus had been confirmed in a commercial dairy herd in the state, but information concerning the county was not made available.
