The first case of highly pathogenic avian influenza (HPAI) in a commercial poultry flock in Illinois during the 2022-23 outbreak has been confirmed.

The  United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) announced that the case was confirmed on February 24 and involved a flock of 18,200 commercial meat turkeys in Wayne County.

Prior to this, Illinois had not had any commercial flocks affected by HPAI. There was a case confirmed in Grundy County on November 30, 2022, which  APHIS initially classified as a commercial upland gamebird producer, but APHIS has since re-classified that flock as “WOAH (World Organisation for Animal Health) Poultry.” There were approximately 8,800 birds in that flock.

All other HPAI cases to be confirmed in Illinois during the current outbreak were in non-commercial flocks that consisted of 60 or fewer birds, and all of those cases were confirmed in 2022.

In addition to Illinois, other states to have confirmed cases of HPAI in commercial operations in 2023 include Pennsylvania, Mississippi, California, Iowa, Virginia, Tennessee and Kansas.
