Idaho reported 32 new confirmed H5N1 cases in dairy herds in the 30 days to June 10, bringing its total to 162. Between 70 and 80 Idaho dairies were under quarantine as of June 11, the highest number in a year.
Nationally there have been 1,141 cattle cases across 20 states since March 2024.
Dairy quarantines reduce milk output in a major dairy state, which can tighten milk supply and support Class III milk prices, with modest effects on dairy-related feed demand.
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.
