The United States Department of Agriculture is testing samples of retail ground beef to ensure safety as bird flu continues to spread in dairy cattle.
These testing decisions come after the USDA implemented a rule requiring lactating dairy cows to test negative on PCR tests before crossing state lines.
This rule came into effect after traces of the avian flu virus was discovered in the U.S. milk supply.
Despite the findings, the Food and Drug Administration is reminding Americans that “the commercial milk supply is safe,” it said in a May 1 update.
