Title 21 › Chapter 9— FEDERAL FOOD, DRUG, AND COSMETIC ACT › Subchapter IV— FOOD › § 350a
Infant formula must have the nutrients the law lists and must be made and tested under rules set by the head of the FDA. If a formula lacks required nutrients, fails the quality rules, or is not made using the required safe manufacturing and quality-control practices, it is treated as adulterated. The FDA must write rules for quality and for good manufacturing practices. Manufacturers must test each batch: certain vitamins (A, B1, C, and E) at the final product stage, check nutrient premixes, and test for any other required nutrients before the product is sent out. The FDA may add nutrients to the required list and then manufacturers must test for those too. Companies must keep testing records, premix certificates, microbiology and packaging data, complaint files, and audit results, generally for at least one year after the product’s shelf life, and make them available to the FDA when asked. Anyone bringing a new formula into interstate commerce must register with the FDA and submit detailed information at least 90 days before marketing (or 30 days when the FDA has declared a shortage), including the formula’s recipe, any processing changes, and assurances that testing and processing meet the rules. After first production, the maker must send the FDA a written summary of test results before sale. The FDA must reply to submissions within 45 days. If a maker knows a product might be unsafe or missing nutrients, they must act. Recalls must follow FDA rules; the FDA will review a recall within 15 days and every 15 days after, and a maker must report recall actions every 14 days. The FDA must notify Congress within 24 hours of a recall and must send an annual report by March 30 about submissions, new ingredients, inspections, and related data. Special formulas for infants with medical needs can have different rules or exemptions, and during shortages the FDA may allow imports of comparable specialty formulas while still keeping recall authority.
