The Federal Food, Drug, and Cosmetic Act (FDCA), enacted in 1938, empowers the U.S. Food and Drug Administration (FDA) to oversee the safety and efficacy of food, drugs, and cosmetics. Its primary purpose is to ensure these products are safe, effective, and not adulterated or misbranded, which involves rigorous testing and approval processes. The FDCA aims to protect public health by regulating the manufacturing, marketing, and distribution of these products, setting standards for labelling and advertising to provide accurate information to consumers. Additionally, it seeks to prevent fraud and deception in the marketplace by prohibiting the distribution of any misbranded or adulterated products.
