Pasteurization Confirmed Effective Against Avian Flu in Dairy Milk

Research shows no live H5N1 virus in pasteurized milk, ensuring consumer safety despite recent infections in cattle.

Highly pathogenic avian flu (H5N1) was detected in dairy cows in the U.S. for the first time in March 2024.
The virus has spread to 139 herds across 12 states, affecting both animals and four humans.
Researchers found no live H5N1 virus in nearly 300 pasteurized milk samples, although viral genetic material was detected in some.
Pasteurization effectively neutralizes the virus, keeping the milk supply safe for consumers.
Dairy industry experts and federal agencies emphasize ongoing biosecurity measures to prevent further spread.
