Typically, the FDA requires that food companies comply voluntarily with FDA regulations prohibiting food misbranding or mislabeling. Failure to comply often results in the FDA sending a Warning Letter to the transgressor. If serious civil or criminal penalties are not available for minor violations of FDA regulations, what incentive or threat is there for companies to avoid or discontinue use of misleading claims on food labels? Is the "public interest" served by the mere issuance of a Warning Letter?
