BHA (butylated hydroxyanisole) is a synthetic preservative found in US cereals, snack mixes, ice cream, and dozens of other packaged foods. The National Toxicology Program classifies it as “reasonably anticipated to be a human carcinogen.” In February 2026, the FDA opened a formal safety reassessment. BHA is still legally permitted in food while that review proceeds.
If you have ever flipped a box of cereal over and scanned the ingredient list, you may have spotted “BHA” or “butylated hydroxyanisole” near the bottom. Same compound, two different names. It has been in the US food supply since 1958. For most of that time it generated little public discussion.
That changed on February 10, 2026, when the US Food and Drug Administration opened a formal post-market safety review of BHA, citing concerns about its classification by the National Toxicology Program.
Here is what the review covers, where BHA shows up in packaged food, and what you can do with that information today.
What Is BHA, and How Did It End Up in Food?
BHA is a synthetic antioxidant. It slows the oxidation of fats and oils, extending shelf life and preventing rancidity. The compound was added to the FDA’s Generally Recognized as Safe (GRAS) list in 1958 under 21 CFR 182.3169, and received a separate food-additive authorization in 1961 under 21 CFR 172.110. Both authorizations are still in force.
The 1958 GRAS designation was established before modern toxicology methods existed. The underlying safety evaluation relied on techniques that predate much of what is now considered standard for assessing chemical risk in humans. The FDA conducted an internal review later, but the original 1958 and 1961 authorizations were never formally updated.
BHA appears in food at low concentrations, typically at or below 0.02% of the fat content of any given product. That threshold was set in the 1950s and has not changed.
Why Is the FDA Reviewing BHA Now?
The National Toxicology Program (NTP), a division of the US Department of Health and Human Services, classifies BHA as “reasonably anticipated to be a human carcinogen” in its 15th Report on Carcinogens (2021). That classification is the trigger for the current reassessment.
The NTP classification is based on animal studies. Rat, mouse, and hamster studies showed forestomach tumors associated with BHA exposure. Studies on fish larvae found hepatocellular carcinoma. Human epidemiological data is described by the NTP as “inadequate,” meaning a direct link between BHA consumption and human cancer has not been established. The classification reflects the weight of animal evidence alongside the absence of exculpatory human data.
On February 10, 2026, the FDA opened Federal Register docket FDA-2026-N-0302 and requested scientific information from the public and industry. The comment window closed April 13, 2026. The FDA stated that the review was prompted by the NTP classification and by concerns about BHA exposure in products marketed to children.
The BHA review is part of a broader FDA post-market chemical safety program launched in May 2025, which also covers titanium dioxide, propylparaben, phthalates, and six artificial food dyes. BD Law’s analysis of the program confirms that BHA and titanium dioxide are both currently receiving formal docket-and-comment reviews under this framework.
What Foods Contain BHA?
BHA is permitted in a wide range of product categories under US federal regulations. The categories confirmed through the relevant CFR sections are:
Under 21 CFR 172.110 (direct food-additive authorization):
- Breakfast cereals
- Dehydrated potatoes (potato flakes, hash brown shreds)
- Shortening used as an emulsifier in baked goods
Under 21 CFR 172.615:
- Chewing gum base
Under 21 CFR 182.3169 (GRAS antioxidant use at up to 0.02% of fat content):
- Lard and rendered animal fats
- Ice cream and frozen desserts
- Candy
- Snack mixes and crackers
- Frozen meals
Products in these categories do not all contain BHA. The authorization allows manufacturers to use it, it does not require them to. Some brands have removed it voluntarily and switched to mixed tocopherols (vitamin E) or rosemary extract. Others have not.
The FDA’s 2026 announcement specifically named cereals, frozen meals, cookies, candy, ice cream, meat products, and “products marketed to children” as exposure categories the reassessment is focused on, as confirmed by Food Safety Magazine’s coverage of the announcement.
How Do You Spot BHA on a Label?
Two names to look for:
- BHA (the abbreviation)
- Butylated hydroxyanisole (the full chemical name)
Both refer to the same compound, as confirmed in the FDA’s food substance database. Manufacturers can use either name. Some use the abbreviation to save label space; others print the full name.
BHA often appears alongside BHT (butylated hydroxytoluene), a related synthetic antioxidant preservative. They are structurally similar but distinct compounds with separate regulatory histories. A label listing “BHA/BHT” contains at least one, possibly both.
If you want to scan ingredient lists across a wide range of packaged foods, the NoJunk food additive checker flags both BHA and BHT in products you scan.
What Does the FDA Review Change?
The review is ongoing. The FDA collected public comments through April 2026 but has not issued a safety determination.
Possible outcomes, none of which have been announced:
- No change: current exposure levels are found acceptable and the existing authorizations remain.
- Revised limits: the permitted concentration is lowered from the current 0.02% threshold.
- Revocation: the GRAS designation and food-additive authorization are withdrawn, forcing reformulation.
- Labeling requirements: manufacturers may be required to flag BHA’s presence more prominently.
The FDA typically takes several years to complete post-market reviews of this scope. The comment window closed in April 2026 and no date for a safety determination has been set publicly.
What is clear from the review is that the FDA considers BHA’s 1958-era authorization overdue for re-examination, given toxicological evidence that did not exist when the original approval was granted.

Frequently Asked Questions
Is BHA safe to eat?
The FDA has not declared BHA unsafe, and it remains legally permitted in US food as of May 2026. The National Toxicology Program classifies it as “reasonably anticipated to be a human carcinogen” based on animal studies, but the human epidemiological evidence is described as “inadequate,” meaning a confirmed link to human cancer has not been established. The FDA’s 2026 reassessment is the agency’s first formal update to BHA’s safety status in decades. A final determination has not been issued.
What is the difference between BHA and BHT?
BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are two chemically distinct synthetic antioxidant preservatives often used together in fat-containing foods. Both slow rancidity. Both have been on the FDA’s GRAS list since the 1950s. The FDA is currently reviewing BHA specifically under docket FDA-2026-N-0302. BHT has a separate regulatory status and is listed separately in the FDA’s post-market review program.
Can BHA appear in products sold in Canada?
Canada’s Food and Drug Regulations permit BHA as a food additive in specific categories, including fats and oils. Products formulated for the US market that contain BHA may also be sold in Canada. Check the ingredient list for “BHA” or “butylated hydroxyanisole” regardless of where the product was manufactured.
Why did the FDA wait until 2026 to review BHA?
BHA received its GRAS designation in 1958 under a framework that predates modern toxicology standards. The FDA did conduct an internal review at a later point but did not revise the authorization at that time. The 2026 reassessment was triggered by the NTP’s 2021 carcinogen classification and by the FDA’s new post-market chemical safety program, launched in May 2025, which is systematically reviewing legacy food additives that were authorized before modern safety standards existed.
What are some alternatives to BHA-containing products?
Whole foods without synthetic preservatives naturally avoid BHA. In packaged foods, you can swap boxed breakfast cereal for plain rolled oats (check the label on flavoured oat products, some contain BHA), packaged snack mixes for raw or dry-roasted nuts, boxed potato flakes for fresh or frozen potatoes, and look for ice cream that lists only cream, milk, sugar, and eggs as ingredients. BHA-containing products cluster heavily in NOVA Group 4 (ultra-processed foods). The NoJunk NOVA score guide explains which product categories fall into that group and how to identify them on a shelf.
