The Center for Food Safety and Applied Nutrition, abbreviated CFSAN, is the branch of the United States Food and Drug Administration responsible for the safety of foods, cosmetics, and dietary supplements. It sets standards for food additives, labelling, and contaminants, oversees the safety of the food supply, and regulates health claims on packaging. Its scientists evaluate new ingredients, monitor chemical and microbial hazards, and respond to emergencies such as contamination incidents. For the food industry, CFSAN’s regulations and guidance documents define what may be sold in America and how it must be labelled, making it one of the world’s most influential food regulators.
