Several key agencies worldwide are involved in toxicology. In the United States, the Environmental Protection Agency (EPA) plays a significant role by regulating chemicals in the environment. The Food and Drug Administration (FDA) oversees the safety of food, drugs, and cosmetics. The Occupational Safety and Health Administration (OSHA) focuses on protecting workers from chemical hazards at the workplace. On the international stage, the World Health Organization (WHO) is involved in setting health-based guidelines for toxic substances.
