USDA confirmed H5N1 highly pathogenic avian influenza in a dairy cattle herd in Morrow County, Oregon, on November 10. It is the first reported case in Oregon; officials are investigating and conducting further testing, while the detection does not change the federal eradication strategy.
The case adds a new state to the outbreak’s geographic reach, but no dairy supply disruption or production impact is reported, so the immediate price effect is likely limited.
