Federal regulators are taking a new step in how processed food ingredients enter the U.S. market, part of a broader push to tighten oversight of the food supply. On August 10, 2026, the Food and Drug Administration announced a proposed rule that would require manufacturers to notify the agency before introducing new food ingredients or additives under the “generally recognized as safe,” or GRAS, pathway. The change would affect food makers nationwide, but critics said the proposal still leaves companies with substantial authority to decide for themselves what can go into food.
FDA proposes a new notice requirement for food additives
The FDA said the proposal would replace a long-standing system that lets companies self-affirm that a substance is GRAS without telling the agency. Acting FDA Commissioner Kyle Diamantas said the change would give regulators “comprehensive visibility” into ingredients entering the market, according to remarks reported by the Associated Press on August 10. The agency said it will accept public comments for 120 days before taking further action.
The scale of the issue is significant. The Associated Press reported that roughly 10,000 additives are allowed in U.S. food, including preservatives, thickeners and packaging-related substances. Under the current framework, manufacturers can decide independently whether some new substances qualify as GRAS, and the FDA has acknowledged that notification is encouraged but not required.
Under the new proposal, companies would have to submit their safety rationale before marketing a new ingredient under the GRAS pathway. Diamantas said the FDA would aim to review those submissions within 180 days and could ask for more information or request a delay if safety questions arise, according to the Associated Press. The FDA also said it plans to publish a list of company-submitted ingredients, though former FDA food official Susan Mayne told the AP that appearing on that list would not mean the ingredient had been determined safe by the agency.
The impact is national, but the full reach is not yet known
Because the FDA proposal applies at the federal level, its practical effect would extend across all 50 states, including grocery shelves, packaged foods and processed products sold in local supermarkets. What is confirmed is the rule would apply to future ingredients introduced through the GRAS pathway if finalized. What is not yet known is how many companies would change product development plans, delay launches or shift to other regulatory channels once the rule is in place.
The government has not released a state-by-state breakdown of foods or manufacturers that would be affected. It also has not published a comprehensive list of self-affirmed GRAS substances currently used without FDA notification. That means shoppers in states from California and Texas to New York and Florida would not immediately see a product list tied to this proposal.
The FDA has also not said when any final rule would take effect after the 120-day comment period. In practical terms, that means there is no immediate change at checkout, in restaurant supply chains or in packaged food labels. The proposal is a procedural shift in oversight, not a ban on specific additives now on store shelves.
Critics say transparency is improving, but independent review is still limited
The main reason the announcement has drawn mixed reactions is that it addresses notification, not automatic premarket approval. Susan Mayne, now a Yale public health expert, told the Associated Press that the proposal is “a reasonable first step” toward a fuller inventory of ingredients, but she said most self-affirmed GRAS ingredients still would not be reviewed by the FDA for safety. That distinction is central to criticism from consumer groups that have argued for years that the GRAS system functions as a loophole.
Melanie Benesh of the Environmental Working Group said the new framework should include stronger safety standards and independent FDA review before chemicals are used in food, according to the AP. Food industry representatives, by contrast, have maintained that internal safety reviews can be as rigorous as the government’s process. The current debate traces back to changes beginning in 1997, when the FDA started allowing companies to independently conclude that certain additives were safe based on publicly available science and expert consensus.
The additive proposal arrived alongside a separate FDA announcement that it had completed work on the federal government’s first definition of ultra-processed food and sent it to the White House for review. Health and Human Services Secretary Robert F. Kennedy Jr. said the two actions would change how the federal government oversees food ingredients and understands the foods Americans eat, according to remarks at HHS headquarters. For consumers, the immediate takeaway is that the proposal would increase federal visibility into future additives, while broader powers to require full FDA review would still depend on Congress.
