WASHINGTON — The U.S. Department of Agriculture announced Friday it will require dairy farms to share samples of unpasteurized milk when requested, in an effort to gather more information about the spread of highly pathogenic avian influenza. Public health officials have tracked the spread of bird flu or H5N1 in domestic poultry flocks for years before the virus began showing up in the country’s dairy herds this March, raising concerns. While the risk to the general public remains low and there is no evidence to suggest bird flu can spread from person to person, nearly 60 people, mostly farmworkers, have contracted the virus this year.
The new milk testing requirements from USDA will apply nationally but will begin first in California, Colorado, Michigan, Mississippi, Oregon and Pennsylvania, the week of Dec. 16. In a written statement Agriculture Secretary Tom Vilsack said “Among many outcomes, this will give farmers and farmworkers better confidence in the safety of their animals and ability to protect themselves, and it will put us on a path to quickly controlling and stopping the virus’ spread nationwide.”

The U.S. Food and Drug Administration has repeatedly tested pasteurized milk on store shelves throughout the country to reaffirm it’s safe to drink. Other dairy products, like cheese and ice cream, have also been found safe. But the FDA continues to urge people against consuming unpasteurized milk, since it doesn’t go through the heating process that kills off viruses and bacteria.
