What GRAS Means and Why It Matters for Food Safety

If you have ever looked up the safety of a food additive in the United States, you have almost certainly encountered the acronym GRAS — "Generally Recognized as Safe." It sounds reassuring, and for many common substances like salt, vinegar, and baking soda, the GRAS designation is perfectly appropriate. But the GRAS system also contains one of the most significant loopholes in American food regulation: the ability for companies to declare their own ingredients safe without FDA review. Understanding how GRAS works — and where it falls short — is essential for any informed consumer.

The Legal Origin of GRAS

The GRAS concept was created by the Food Additives Amendment of 1958, which amended the Federal Food, Drug, and Cosmetic Act. The amendment established that any substance intentionally added to food is a "food additive" and requires pre-market approval from the FDA — unless it is "generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use."

The original intent was practical: Congress recognized that thousands of substances with long histories of safe use — salt, pepper, vinegar, corn starch — should not require the same approval process as a novel synthetic chemical. The 1958 amendment grandfathered in approximately 700 substances based on their established safety record.

This made sense in 1958. The problems emerged in how the system evolved over the following decades.

The Self-Affirmed GRAS Loophole

The critical distinction in the GRAS system is between FDA-affirmed GRAS and self-affirmed GRAS. Here is how they differ:

FDA-affirmed GRAS: The FDA reviews safety data and formally publishes its determination that a substance is GRAS. These are listed in 21 CFR Parts 182, 184, and 186. This is the more rigorous pathway.
Self-affirmed GRAS: A company convenes its own panel of experts, evaluates safety data, and independently concludes that its substance is GRAS. The company may voluntarily notify the FDA through the GRAS Notification Program (GRN), but it is not required to do so.

This means a company can introduce a new substance into the food supply without ever informing the FDA, as long as it has assembled expert consensus that the substance is safe. The FDA does not know about these substances, cannot track them, and cannot evaluate whether the safety determination was rigorous.

A 2014 study by the Natural Resources Defense Council (NRDC) analyzed the GRAS notification database and found that of the 451 voluntary GRAS notifications submitted between 1997 and 2012, the FDA only formally affirmed 3 as GRAS. The majority received "no questions" letters, meaning the FDA had no objections but did not independently validate the safety data. And these are only the notifications that were voluntarily submitted — an unknown number of self-affirmed GRAS determinations were never reported to the FDA at all.

Conflicts of Interest in Expert Panels

A 2013 study published in JAMA Internal Medicine examined the composition of expert panels used in 451 GRAS determinations. The findings were striking:

100% of GRAS determinations were made by panels with financial ties to the company seeking the GRAS designation.
In 22.4% of cases, the panel member was an employee of the company.
In 13.3% of cases, the panel member had been selected by a consulting firm hired by the company.
Not a single determination included an expert panel member with no financial connection to the interested party.

This does not mean every self-affirmed GRAS determination is wrong. Many are conducted by reputable toxicologists using sound methodology. But the structural conflict of interest — where the entity paying for the safety review is the same entity that profits from a "safe" determination — undermines public confidence and scientific independence.

How GRAS Differs from EU Approval

The European Union does not have a GRAS equivalent. Under Regulation (EC) No 1333/2008, every food additive must undergo a full safety evaluation by EFSA before it can be authorized for use. The process works as follows:

The manufacturer submits a dossier including toxicological studies, proposed uses, and estimated exposure levels.
EFSA's Panel on Food Additives and Flavourings evaluates the data and publishes a scientific opinion.
The European Commission, with input from member states, decides whether to authorize the additive and sets conditions of use (maximum levels, food categories).
Every authorized additive is assigned an E-number and added to the Union List (Annex II of the regulation).

Critically, EFSA is also conducting a systematic re-evaluation of all food additives authorized before 2009. This program, which began in 2010 and is ongoing, has already resulted in revised ADIs, restricted uses, and in the case of titanium dioxide (E171), a complete ban. No equivalent systematic re-evaluation exists in the US.

The result: the EU has a positive list system (only what is explicitly approved can be used), while the US has a hybrid system where some additives are formally approved, some are FDA-affirmed GRAS, and an unknown number are self-affirmed GRAS without any government awareness.

GRAS vs. Food Additive Petition

When a substance does not qualify for GRAS status — typically because it is novel and lacks a history of safe use — the manufacturer must submit a Food Additive Petition (FAP) under 21 CFR Part 171. This is a far more rigorous process:

The petition must include full toxicological data, including two-year chronic feeding studies in at least two animal species.
The FDA reviews the data and publishes a regulation authorizing the additive (or rejecting it).
Authorized food additives are listed in 21 CFR Parts 172–180 with specific conditions of use.
The entire process typically takes 2–5 years and costs $1–3 million in testing and regulatory fees.

The time and cost differential between GRAS self-affirmation (months, tens of thousands of dollars) and a food additive petition (years, millions of dollars) creates a strong economic incentive to pursue the GRAS pathway even for substances where it may not be appropriate.

Recent Reforms and Ongoing Criticism

The FDA has acknowledged the limitations of the GRAS system. In 2016, the agency finalized a rule updating the GRAS notification process, replacing the older "GRAS affirmation petition" with the current voluntary notification program. The rule clarified the criteria for GRAS determinations but did not address the fundamental issue: notifications remain voluntary.

In 2022, the Government Accountability Office (GAO) issued a report recommending that the FDA take steps to "ensure the safety of substances that companies market as GRAS without notifying FDA." The report found that the FDA could not determine how many self-affirmed GRAS substances were in the food supply, nor could it systematically identify safety concerns.

Legislative efforts have been introduced but not passed. The SAFE Food Act, introduced in Congress multiple times since 2015, would require mandatory pre-market notification for all GRAS determinations and give the FDA authority to reassess existing GRAS substances. As of 2026, the bill has not advanced out of committee.

How Consumers Can Protect Themselves

Given the gaps in the GRAS system, informed consumers should take an active role in evaluating food additives:

Use independent databases: The AdditiveChecker Analyzer provides safety assessments based on multiple regulatory sources, not just FDA GRAS status. Paste any ingredient list to see which substances have been flagged by EFSA, IARC, or independent research.
Look beyond "GRAS." A GRAS designation means experts (selected by the manufacturer) believe a substance is safe. It does not mean the FDA has reviewed or endorsed that conclusion.
Check the regulatory comparison. If a substance is GRAS in the US but restricted or banned in the EU, that discrepancy is worth investigating. Our additive guides include cross-jurisdictional regulatory status for each entry.
Support regulatory reform. Consumer advocacy groups like the Center for Science in the Public Interest and the Environmental Working Group actively campaign for mandatory GRAS notifications and systematic re-evaluation of existing additives.

The GRAS system was designed for a simpler era when the food supply contained fewer novel substances. As the number of food additives has grown into the thousands, the gap between the system's design and today's reality has become difficult to ignore. Until meaningful reform occurs, the responsibility for due diligence falls disproportionately on the consumer.
