Morrow County dairy under quarantine for bird flu

MORROW COUNTY — The Oregon Department of Agriculture reported milk from a Morrow County dairy tested positive for highly pathogenic avian influenza, the first detection at a dairy in Oregon. The affected dairy is under quarantine, the ag department announced Tuesday, Nov. 10, and the milk and food supply remain safe for consumption. Preliminary detection of HPAI was identified through Oregon’s routine statewide milk surveillance program, with preliminary results reported by the Oregon Veterinary Diagnostic Laboratory at Oregon State University on Nov. 6. The DOA immediately initiated an on-farm investigation and submitted additional samples to the U.S. Department of Agriculture National Veterinary Services Laboratory for confirmation. Positive results were confirmed on Nov. 10. Oregon’s routine statewide milk surveillance program identified the detection, the state ag department reported, and no additional affected dairies have been identified at this time.
