The US Food and Drug Administration (FDA) Center for Food Safety and Applied Nutrition (CFSAN) oversees the regulation of food ingredients,1, 2 and premarket approval is required before a food ingredient can be brought to market. Food ingredients include the following:
- Food additives
- Food components are ingredients directly added to food.
- Food contact substances are used in packaging or production processes that indirectly contact food.
- Food colour additives impart colour.
Manufacturers submit safety information on a food ingredient to CFSAN using one of three types of petition:3
- For direct food additives (food components) or food colour additives, a Food or Color Additive Submission is used. Direct food additives may be exempt from the regulatory process if they are prior sanctioned substances or are generally recognized as safe (GRAS).4
- For indirect food additives (food contact substances), a Food Contact Substance Submission is used.
- Companies seeking voluntary GRAS status for direct food additives submit a GRAS Notice. GRAS status means that the direct food additive is safe under the conditions of intended use according to qualified scientific experts; however, this status can be reversed and may be revoked on the basis of new data indicating poor safety.
The FDA provides general guidelines5, 6 about tests that may be used to infer a reasonable certainty of no harm. In general, safety is determined largely using information reflecting chemical identity, exposure, and the results of a flexible battery of toxicology tests. While agency guidelines recommend animal tests, these are not required to achieve regulatory acceptance, as noted in the FDA Redbook:
FDA’s guidance for toxicity studies for food ingredients continue to emphasize that there is no substitute for sound scientific judgement. This guidance presents recommendations – not hard and fast rules. If an investigator believes that he/she can provide the Agency with useful toxicological information by modifying a recommended study protocol, and is able to support the modification with sound scientific arguments, then the investigator should propose the modified protocol to the appropriate program division within [the Office of Food Additive Safety]. As always, petitioners and notifiers should consult with the FDA prior to and during the design of study protocols for toxicity studies and/or before commencement of studies.7
Thus, non-animal testing approaches can be used to obtain premarket approval of or GRAS status for food ingredients. The PETA Science Consortium International e.V. has developed a user-friendly workflow to help petitioners who are interested in pursuing non-animal food ingredient safety assessment, available here.
