The United Farm Workers union says many more US farm workers have been infected with H5N1 bird flu than officially reported, with some showing very severe symptoms. Officially 73 people have been recorded as infected since 2024, and H5N1 is spreading across US cattle farms in dozens of states.
The story concerns worker health and reporting rather than herd losses or trade, so its direct effect on feed supply and prices is limited. Ongoing spread in dairy herds could eventually affect milk output.
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.
