As wild birds begin their fall migration, the risk of highly pathogenic avian influenza (HPAI) spreading to domestic poultry in Oregon is increasing. In October, the U.S. Department of Agriculture’s National Veterinary Services Laboratory confirmed HPAI in five mixed-species backyard poultry flocks located in Deschutes, Malheur, and Wallowa counties. The initial testing was conducted by the Oregon Veterinary Diagnostic Laboratory at Oregon State University, with results later verified by federal authorities.
Dr. Ryan Scholz, State Veterinarian for the Oregon Department of Agriculture (ODA), responded by placing the affected farms under quarantine. An ODA team then humanely euthanized all poultry on these properties to prevent further spread of the disease. “None of the animals from the farms entered the food supply chain or were intended for the commercial food market,” according to officials.
Since May 2022, Oregon has seen three commercial poultry flocks and 47 backyard flocks affected by HPAI. Health officials emphasize that properly cooked meat and eggs remain safe for consumption and recommend choosing pasteurized milk and dairy products as an additional precaution.
The ODA urges poultry owners to review biosecurity measures during this period of heightened risk. Recommendations include restricting access to properties with birds, keeping domestic birds separate from others, using dedicated footwear around birds, washing clothing after contact with birds, and disinfecting equipment after visiting locations where other birds are present. Owners should also quarantine new or returning birds for 30 days before integrating them into existing flocks.
Any cases of illness or death among domestic birds should be reported immediately to the ODA at 503-986-4711. Reports regarding dead wild birds should be directed to the Oregon Department of Fish and Wildlife at 1-866-968-2600; individuals are advised not to handle dead wild birds themselves.
