What government agency regulates most US food labeling?

The Food and Drug Administration (FDA) regulates most food labeling in the United States, overseeing the labeling of packaged foods, dietary supplements, and beverages. The U.S. Department of Agriculture (USDA) also plays a role, particularly in labeling meat, poultry, and egg products. Both agencies ensure that labels provide accurate information and comply with federal standards to protect consumer health and inform purchasing decisions.
