The Food and Drug Administration (FDA) is a U.S. government agency responsible for protecting public health. It oversees the safety and effectiveness of food, drugs, medical devices, and cosmetics. The FDA ensures that products meet specific standards before they can be sold to consumers. In addition to regulating products, the FDA also monitors food labeling and advertising to prevent misleading claims. The agency plays a crucial role in responding to public health emergencies and provides guidance on the safe use of products, helping to maintain the overall health and safety of the population.
