USDA confirmed HPAI in a dairy herd in Morrow County, Oregon, on November 10. The report also says 50 dairy herds across five states had tested positive in the preceding 30 days, including new detections in Idaho and Washington.

After 22 past bullish disease events, Milk (Class III) moved a median -0.0% over 5 sessions (45% higher; middle half -0.9% to +0.5%), and -2.8% over 20.
