On October 6, 2005, the U.S. Department of Agriculture´s (USDA) National Veterinary Services Laboratory (NVSL) confirmed Highly Pathogenic Avian Influenza (HPAI) in a backyard flock of ducks and chickens in Wallowa County. This is the first confirmed case of HPAI in Wallowa County. Samples from the flock were first taken to the Oregon Veterinary Diagnostic Laboratory (OVDL) at Oregon State University (OSU) for testing. OSU confirmed the presence of HPAI on October 3, 2025, and NVSL confirmed the results three days later. Additional cases are currently being investigated, and more information will be made available as results are confirmed.
