A commercial broiler breeder operation in Bledsoe County is the latest case of highly pathogenic avian influenza (HPAI) to be reported in the United States.

According to information on the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service website, the infection was confirmed on November 15, and there were 20,900 birds in the flock.

Prior to this, there had not been any cases of HPAI in commercial poultry in Tennessee, although thee state did have two previous cases in backyard poultry.

With the case in Tennessee, 26 states have now had confirmed cases in commercial operations in 2022. However, three of those states only had upland gamebird operations affected. Of those 26 states, Tennessee ranks 22nd in terms of the number of birds affected.
