A commercial broiler breeder flock and a commercial turkey flock – both in California – are the latest cases of highly pathogenic avian influenza (HPAI) in the United States.
According to information on the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service webpage, the broiler breeder flock included 22,900 birds in Fresno County, while the turkey flock included 30,800 birds in Tuolumne County.
Fresno County has now had three confirmed cases of HPAI – all of which were broiler breeder flocks – with the first one being confirmed on August 22. Tuolumne County has now had four cases of HPAI, and all of those have involved commercial turkey flocks. That county’s first case was confirmed on August 26.
In total, California has had eight cases of HPAI in commercial poultry. The remaining one was confirmed in a flock of commercial meat turkeys in Sacramento County on August 30. The state has also had four cases of HPAI in backyard flocks. Including both the commercial and backyard poultry, California has lost an estimated 480,010 birds in 2022 as a result of the avian influenza outbreak.
Nationwide, more than 40 million head of commercial poultry have been lost to HPAI in 2022.
