Oregon confirmed its first highly pathogenic avian influenza case in commercial dairy cattle at a Morrow County dairy. Officials also report growing numbers of infected migratory waterfowl in the Willamette Valley, and a large wild bird die-off was reported in Washington.
Infection in dairy herds can reduce milk output and raises concern about spread to other livestock, while wild-bird outbreaks in the Pacific Northwest signal rising poultry risk. Milk supply disruption could modestly support dairy prices.
After 24 past bullish disease events, Milk (Class III) moved a median -0.1% over 5 sessions (42% higher; middle half -2.1% to +0.5%), and -2.8% over 20.
