The Federal Food, Drug, and Cosmetic Act (FFDCA) was enacted in 1938 and gave the U.S. Food and Drug Administration (FDA) authority to oversee food, drugs, and cosmetics. It was passed in response to the 1937 Elixir Sulfanilamide tragedy that killed over 100 people. The FFDCA introduced requirements for pre-market approval of new drugs and mandated that labels disclose ingredients and directions for safe use. It has since been amended multiple times to both strengthen and clarify the FDA's regulatory authority.
