Key Takeaways

  • The USDA is mandating HPAI H5N1 testing in milk cows due to positive tests found in pasteurized milk samples.
  • Further investigation is ongoing to confirm if live, infectious virus is present.

  • Authorities believe pasteurization remains effective against HPAI H5N1, but ongoing research is crucial.

Bird Flu News on the Rise

The United States Department of Agriculture (USDA) announced a mandatory testing program for HPAI H5N1, a highly pathogenic avian influenza strain, in milk-producing cows.

This follows the Food and Drug Administration's (FDA) announcement of positive HPAI H5N1 tests in samples of pasteurized milk found on store shelves.

This bird flu news has raised alarms, prompting more investigations to determine if the virus is infectious or remnants of dead virus particles left over from the pasteurization process.

Federal authorities have identified "isolated" mutations in the virus found in cows, that were thought to be spread by wild birds.
