Oregon Confirms First HPAI Detection in Dairy Cattle: Dairy Quarantined, No Human Cases
The Oregon Department of Agriculture announced that milk from a dairy in Morrow County, Oregon, tested positive for highly pathogenic avian influenza (HPAI) — the first detection of HPAI in Oregon dairy cattle — and that the affected dairy is under quarantine.
The department said the state veterinary diagnostic laboratory obtained preliminary positive results on November 6, and the USDA National Veterinary Services Laboratory confirmed the results on November 10. No other dairies are currently affected, no human cases associated with this incident have been identified in Oregon, and the risk to the public is low.
State Veterinarian Dr. Ryan Scholz said infected cows generally recover within weeks, and the department is working with the dairy and federal agencies on monitoring while the state's milk supply continues under existing testing and pasteurization protocols.
