The United States Federal Food, Drug, and Cosmetic Act (abbreviated as FFDCA , FDCA , or FD&C ), is a set of laws passed by Congress in 1938 giving authority to the U.S. Food and Drug Administration (FDA) to oversee the safety of food , drugs, medical devices, and cosmetics. A principal author of this law was Royal S. Copeland , a three-term U.S. Senator from New York. In 1968, the Electronic Product Radiation Control provisions were added to the FD&C. Also in that year the FDA formed the Drug Efficacy Study Implementation (DESI) to incorporate into FD&C regulations the recommendations from a National Academy of Sciences investigation of effectiveness of previously marketed drugs. The act has been amended many times, most recently to add requirements about bioterrorism preparations.
