USDA’s Animal and Plant Health Inspection Service (APHIS) confirmed the presence of highly pathogenic (HPAI) H5N8 avian influenza in guinea fowl and chickens from a small backyard poultry flock in Winston, Oregon. The flock of approximately 100 birds had access to the outdoors. A pond and a marsh on the premises are frequented by migratory birds. USDA reiterated the H5N8 virus has NOT been found in commercial poultry anywhere in the United States, and there is no immediate public health concern, as the H5N8 virus has been found in birds in other parts of the world and has not caused any human infection to date.
USDA notified the World Organization for Animal Health (OIE) of this detection as required by the OIE. USDA expects trading partners to respond to this reported detection according to OIE’s science-based standards. USDA is working with trading partners to minimize trade impacts on poultry and poultry products as much as possible. USDA is coordinating closely with its partners, including: Washington State Department of Agriculture, the Oregon Department of Agriculture, the U.S. Department of the Interior and the U.S. Department of Health and Human Services, on avian influenza surveillance, reporting, and control.
All bird owners, whether commercial producers or backyard enthusiasts, are encouraged to practice good biosecurity, prevent contact between their birds and wild birds, and to report sick birds or unusual bird deaths to State/Federal officials, either through your state veterinarian or through USDA’s toll-free number at 1-866-536-7593.
