Avian Influenza Detected in US Dairy Cows and Seals

Milk from dairy cows in Texas, Kansas, and New Mexico has tested positive for bird flu, marking the first time the virus has been found in US livestock. The commercial milk supply is safe, and the risk to people is low, according to the USDA. The virus is affecting older dairy cows, causing decreased lactation and low appetite, but pasteurization kills viruses and is required for milk sold through interstate commerce. The federal government's tests did not detect any changes to the virus that would make it spread more easily to people. Dairy farmers have implemented enhanced biosecurity efforts, and officials are closely monitoring the situation.
