H5N1 bird flu is spreading through US dairy cattle and poultry flocks, with at least one human death reported in Washington state. CDC data show infections confirmed in dairy herds in six states and in poultry flocks across 17 states over the past 30 days.
Health experts warn that co-circulation with seasonal influenza could raise the risk of a human-transmissible strain.
Expanding infections in poultry and dairy herds can cut egg and milk supply and lead to culls, tightening animal protein and feed demand dynamics. The pandemic-risk angle is a broader health concern with a limited direct effect on feed grain prices.
After 24 past bullish disease events, Milk (Class III) moved a median -0.1% over 5 sessions (42% higher; middle half -2.1% to +0.5%), and -2.8% over 20.
