The Food and Drug Administration is suspending a quality control program for testing of fluid milk and other dairy products due to reduced capacity in its food safety and nutrition division, according to an internal email seen by Reuters.

The suspension is another disruption to the nation’s food safety programs after the termination and departure of 20,000 employees of the Department of Health and Human Services, which includes the FDA, as part of Donald Trump’s effort to shrink the federal workforce.

The FDA this month also suspended existing and developing programs that ensured accurate testing for bird flu in milk and cheese and pathogens like the parasite Cyclospora in other food products.
