H5N1 bird flu has been confirmed in California dairy cows, extending the US dairy outbreak to a 14th state. More than 190 herds have been infected nationally since March, along with 13 dairy and poultry farm workers.
Spread into a major dairy state raises the risk of lower milk output and herd culling, which can pressure milk prices. Broader poultry exposure would also add to demand uncertainty for feed.
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.
