Overview

• USDA’s National Veterinary Services Laboratory confirmed HPAI in a backyard flock of ducks and chickens in Wallowa County, Oregon, marking the county’s first case.
• The Oregon Department of Agriculture quarantined the property and humanely euthanized all birds, and officials said none entered the food supply.
• The Nevada Department of Wildlife reported 10 ducks testing positive for avian influenza, seven highly pathogenic, from 70 samples at Key Pittman WMA and Pahranagat National Wildlife Refuge.
• Final confirmation of the Nevada results is pending from the U.S. Department of Agriculture, and wildlife officials described current human risk as low.
• Authorities urged hunter precautions including avoiding sick or dead birds, using protective gear when cleaning game, cooking to 165°F, keeping dogs from contact, and noted detections typically rise during migration seasons; Oregon has recorded three commercial and 47 backyard affected flocks since 2022.
