USDA confirmed H5N1 genotype B3.13 in an Indiana dairy herd on November 2, the state’s first reported case in cattle. Routine milk testing detected the infection, bringing the number of states with infected dairy herds to 21; state and federal officials are investigating the case.
Further spread could disrupt dairy operations and reduce milk output, posing a modest downside risk to milk supply and prices. The report concerns one newly detected herd, so the direct market impact is likely limited.
After 10 past bearish disease events, Milk (Class III) moved a median +0.1% over 5 sessions (60% higher; middle half -0.5% to +0.7%), and +2.2% over 20.
