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.
Overview
- 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.
