Raw samples nationwide will now be collected and shared with the U.S. Department of Agriculture (USDA) in order to test for bird flu, according to a new federal order issued by the agency on Friday.

The new federal order by the USDA includes three new requirements. Raw milk samples must now be shared upon request by dairy farms, bulk milk transporters or dairy processing facilities.

Herd owners with cattle that test positive for bird flu have to provide information that allows health officials to perform contact tracing and disease surveillance. Private laboratories and state veterinarians must now report positive bird flu test results to the USDA.

The decision comes after bird flu virus was found in samples of raw milk from a California farm, which issued a recall of all of its raw milk products earlier this week. The farm was also placed under quarantine by state health officials.
