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. Grade "A" milk, or fluid milk, meets the highest sanitary standards. The testing program was suspended because FDA's Moffett Center Proficiency Testing Laboratory, part of its division overseeing food safety, "is no longer able to provide laboratory support for proficiency testing and data analysis," the email said. The FDA's proficiency testing programs ensure consistency and accuracy across the nation's network of food safety laboratories. Laboratories also rely on those quality control tests to meet standards for accreditation.
