The U.S. Food and Drug Administration (FDA) is an agency of the United States Department of Health and Human Services and is responsible for the safety regulation of most types of foods, dietary supplements, drugs, vaccines, biological medical products, blood products, medical devices, radiation-emitting devices, veterinary products, and cosmetics.
Most states have adopted the FDA Food Code definition of potentially hazardous foods or the previous FDA/AFDO Retail Code or FDA Food Service Code, which do not state a specific a w or pH value, but use a general definition that has been interpreted by the FDA as including a w = 0.85 and pH =4.6.
