Bird Flu in U.S. Raises Concerns Over Raw Milk and Pandemic Potential

H5N1 infections linked to livestock and raw milk prompt public health warnings as experts monitor mutation risks.

The H5N1 bird flu virus has infected cattle and poultry in 16 states, with 60 human cases reported nationwide, including one in Texas and 29 in California.
Most human infections have been linked to direct contact with infected livestock, and there is no confirmed human-to-human transmission in the U.S. so far.
Health officials warn that raw milk from infected cows contains high levels of the virus, with one California dairy issuing a recall after contaminated milk was detected.
A study from Scripps Research highlights the risk of a single mutation in H5N1 potentially enabling efficient human-to-human transmission, raising pandemic concerns.
Public health agencies are increasing testing of raw milk and infected herds, while urging precautions for those handling livestock or consuming unpasteurized dairy products.
