The Iowa Department of Agriculture and Land Stewardship and the USDA’s Animal and Plant Health Inspection Service detected a case of Highly Pathogenic Avian Influenza in a commercial turkey flock in Calhoun County, Iowa. This is Iowa’s eighth detection of HPAI within domestic birds in 2025. As the fall wild bird migration continues, that’s typically when infections in domestic flocks pick up. Clinical signs of infection include a sudden increase in bird deaths without any clinical signs, lethargy, and a lack of appetite.
It can also include a decrease in egg production, or soft, thin-shelled, or misshapen eggs, and a swelling of the head, eyelids, comb, wattles, and hocks. Remember, it remains safe to enjoy eggs and poultry products. Consumers are reminded to properly handle and cook eggs and poultry products, including cooking to an internal temperature of 165 degrees Fahrenheit. The CDC said the threat to the public remains low.
