The Food and Drug Administration (FDA) recently issued a letter to the food industry restating the requirements of the Federal Food, Drug, and Cosmetic Act regarding the marketing of conventional foods containing novel ingredients, including botanicals. FDA is issuing this letter because of the significant growth in the marketing of foods containing these ingredients. FDA is concerned that some botanical and other novel ingredients that are being added to conventional foods are neither approved food additives, nor generally recognized as being safe for these uses. This letter serves as a reminder to the industry of the longstanding legal requirements governing conventional food products.
