The Federal Food, Drug, and Cosmetic Act (FFDCA) is a key piece of legislation enacted in 1938 that provides the legal framework for the regulation of food, drugs, and cosmetics in the United States. This act empowers the FDA to oversee the safety and efficacy of these products, ensuring they meet specific standards before they can be marketed to consumers. The FFDCA also established protocols for labeling and advertising, setting the groundwork for food safety and consumer protection.
