The Food and Drug Administration is part of the Public Health Service of the U.S. Department of Health and Human Services. It is the regulatory agency responsible for ensuring the safety and wholesomeness of all foods sold in interstate commerce except meat, poultry and eggs (which are under the jurisdiction of the U.S. Department of Agriculture). FDA develops standards for the composition, quality, nutrition, safety and labeling of foods including food and color additives. It conducts research to improve detection and prevention of contamination. It collects and interprets data on nutrition, food additives and pesticide residues. The agency also inspects food plants, imported food products and feed mills that make feeds containing medications or nutritional supplements that are destined for human consumption. And it regulates radiation-emitting products such as microwave ovens. FDA also enforces pesticide tolerances established by the Environmental Protection Agency for all domestically produced and imported foods, except for foods under USDA jurisdiction.
