USDA said the cattle illness first reported in Texas is highly pathogenic avian influenza, while noting the situation is rapidly evolving. Dairy futures, especially Class III and cheese, traded higher in response.
Spot cheese held near the December low of $1.39 and recovered slightly.
Avian influenza detected in dairy cattle raises uncertainty about herd health and milk output, which supports dairy prices. Lower herd numbers would tighten milk supply and reduce demand for dairy-related feed.
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.
