Anyone involved with poultry production from the small backyard to the large commercial producer should review their biosecurity activities to assure the health of their birds, says USDA. The department has a list of tools producers can use to help with biosecurity measures.

APHIS is working closely with state animal health officials on joint incident responses. State officials quarantined the affected premises, and birds on the properties will be depopulated to prevent the spread of the disease. Birds from the flocks will not enter the food system.

Signs of avian influenza include: birds dying without clinical signs; lack of energy; decreased egg production; soft-shelled or misshapen eggs; swelling or purple discoloration of the head, eyelids, comb, and hocks; nasal discharge; coughing; sneezing; incoordination; and diarrhea. USDA has a resource with images to help identify discoloration and other clinical signs.

If farmers have a bird they believe has passed away because of avian influenza, state officials encourage them to double bag the bird and refrigerate to preserve it for testing.

Avian influenza is not a foodborne illness and does not pose a food-safety risk.
