Avian influenza was confirmed in an Oregon dairy herd for the first time, making Oregon the 22nd state with infected cattle. Washington's outbreak has grown to dozens of infected herds and has been linked to 3 human infections, including 1 death.
Growing dairy herd infections in Washington and a new state add to the risk of lower milk output in key dairy regions. The impact on milk prices is likely modest so far because no supply disruption has been reported.
After 22 past neutral disease events, Milk (Class III) moved a median -0.1% over 5 sessions (41% higher; middle half -1.4% to +0.5%), and +0.2% over 20.
