Answer: Yes — Butylated Hydroxyanisole is banned in 1 country/region including Japan (banned for use in foods containing fats and oils). The FDA still allows it in US food. Commonly found in: Some Post and Kellogg's cereals (certain US formulations), Chewing gum, Potato chips.
TL;DR: Butylated Hydroxyanisole is restricted in the EU but allowed in the US (food additives).

Butylated hydroxyanisole (BHA) is a synthetic phenolic antioxidant preservative derived from petroleum. It is a mixture of two isomeric compounds (2-BHA and 3-BHA). BHA prevents fats and oils from oxidizing (going rancid), extending shelf life. Its chemical formula is C11H16O2.
BHA is used at very low concentrations (typically 0.02% of fat content) to prevent oxidative rancidity in fats, oils, and fat-containing foods, extending shelf life. It is cost-effective, stable under heat, and used in snack foods, cereals, chewing gum, packaging materials, and cosmetics.
BHA is classified by the International Agency for Research on Cancer (IARC) as Group 2B (possible human carcinogen) based on studies showing it causes papillomas and squamous cell carcinomas of the forestomach in rats, hamsters, and mice at high doses. A 1983 NTP bioassay confirmed these findings. The National Toxicology Program lists BHA as 'reasonably anticipated to be a human carcinogen' in its Report on Carcinogens. The forestomach is an anatomical structure found in rodents but not humans, creating some uncertainty about direct extrapolation. EFSA's 2012 re-evaluation (EFSA Journal 2012;10(10):2588) concluded that BHA may have endocrine-disrupting potential based on animal data showing interactions with estrogen receptors and androgenic hormone pathways. EFSA found the ADI of 1 mg/kg body weight but noted concerns about endocrine effects. Japan banned BHA for use in foods containing fats and oils, consistent with its generally precautionary approach to synthetic food preservatives. In cosmetics, the EU Scientific Committee on Consumer Safety (SCCS) has assessed BHA and found potential endocrine-disrupting effects at dermal exposure levels. EWG rates BHA as high-concern in Skin Deep cosmetics database. The antioxidant paradox applies: while BHA prevents lipid oxidation in foods, it may paradoxically act as a pro-oxidant in certain biological contexts at certain doses.

Regulatory status is not the same as a proven health effect — read the cited sources for their exact wording, and consult a doctor for decisions about your or your family's health.
Mixed tocopherols (natural vitamin E, E306-309), rosemary extract (E392), ascorbyl palmitate (fat-soluble vitamin C), and natural antioxidant blends effectively replace BHA. Most European and US organic/natural food brands use these alternatives. Modified atmosphere packaging and vacuum sealing extend shelf life without chemical preservatives.
IARC classifies BHA as Group 2B (possible human carcinogen) based on rodent forestomach tumors at high doses. The NTP lists it as 'reasonably anticipated to be a human carcinogen.' Japan banned it; the EU restricts it. The FDA permits it at low levels.
Some cereals, potato chips, chewing gum, shortening, lard, and many packaged snack foods. Also found in numerous cosmetics and medications. Look for 'BHA,' 'butylated hydroxyanisole,' or 'E320.'
Animal studies show BHA interacts with estrogen receptors. EFSA's 2012 review found evidence of endocrine-disrupting potential. The EU SCCS flagged it in cosmetics. Human relevance at typical dietary exposures is uncertain but warrants precaution.
BHA (E320) is not completely banned in EU food but is heavily restricted — banned in baby food, restricted in other categories. Japan has a complete food ban.
Both are synthetic phenolic antioxidant preservatives but different chemical structures. BHA is IARC Group 2B; BHT has more complex carcinogenicity data with some bidirectional effects. Both are restricted in Japan and EU but broadly permitted in the US.
Check labels for 'BHA,' 'butylated hydroxyanisole,' or 'E320.' Choose organic-certified products. Look for natural antioxidants like rosemary extract or mixed tocopherols. Use EWG Skin Deep for BHA-free personal care products.

FDA considers it safe at permitted levels. IARC Group 2B status, NTP carcinogen listing, Japan's ban, and EU restrictions reflect scientific uncertainty. The precautionary principle drives restrictions in other countries.
Particularly concerning in cosmetics due to dermal absorption adding to total body exposure. EU SCCS found potential endocrine-disrupting effects. EWG rates it high-concern. EU has restricted concentrations in cosmetics.
