E-numbers banned in the EU but allowed in the US: the full 2026 list
TL;DR
- Titanium dioxide (E171) has been banned across all EU member states since August 2022 (EFSA opinion 2021) but remains legal in US candies, frostings and chewing gums.
- BHA (E320) and BHT (E321) are classified as "possibly carcinogenic" by IARC and restricted in the EU, while the FDA still considers them GRAS (Generally Recognized As Safe).
- Brominated vegetable oil (BVO) is banned in the EU and was finally pulled by the FDA in August 2024, but US stockpiles and small-brand sodas may still contain it through 2026.
- Red 3 (Erythrosine, E127) is banned in EU cosmetics and restricted in food; the FDA banned it from US food only in January 2025, with a compliance deadline of January 2027.
- NutriDecrypte analyzes 230+ data points per product across 13 official sources (EFSA, ANSES, FDA, IARC) to flag additives banned on either side of the Atlantic.
If you grew up eating Skittles, Pop-Tarts or Mountain Dew in the United States, you have probably ingested additives that European regulators pulled from supermarket shelves years, sometimes decades, ago. The gap between the EU and US food safety frameworks is not a minor footnote: it is a structural philosophical divide that shapes what ends up on your plate.
The European Union operates under the precautionary principle (Article 191 of the Treaty on the Functioning of the EU), meaning an additive must be proven safe before it is allowed on the market. The US Food and Drug Administration (FDA) uses a different standard: the GRAS (Generally Recognized As Safe) system, established by the Food Additives Amendment of 1958, which lets manufacturers self-certify the safety of new ingredients. A 2013 study published in JAMA Internal Medicine found that 64% of GRAS submissions were determined by employees or consultants of the companies marketing the additive, with no independent FDA review.
In this guide, NutriDecrypte, the independent label decoder, walks you through the most controversial additives that remain legal in US food but are banned, restricted or being phased out in the EU. Each entry includes the official regulatory citation, the scientific basis for the ban, and the typical US products where the additive still appears. No marketing spin, just the data.
Why does the EU ban additives the FDA allows?
The transatlantic divide on food additives is not about taste, lobbying alone or regulatory speed. It comes down to two opposing legal frameworks.
The EU precautionary principle
Under Regulation (EC) No 1333/2008 on food additives, the European Commission mandates that any new additive must pass a full safety evaluation by the European Food Safety Authority (EFSA) before authorization. EFSA reviews toxicological studies, genotoxicity, carcinogenicity, reproductive effects and cumulative exposure. If the data show "unacceptable risk" or even significant uncertainty, the additive is rejected or withdrawn.
EFSA also re-evaluates all 320+ authorized additives on a rolling basis under the 2010-2020 re-evaluation program (extended to 2025). This is how titanium dioxide, considered safe for decades, was suddenly delisted in 2022.
The US GRAS system
The FDA, by contrast, operates under the Federal Food, Drug, and Cosmetic Act (FD&C Act). Any substance "generally recognized" as safe by qualified experts can bypass premarket FDA review. Companies are not even required to notify the FDA when they self-certify a new ingredient as GRAS, although a voluntary notification system exists.
The result, documented by the Environmental Working Group (EWG) and the Pew Charitable Trusts (2014 report), is a regulatory backlog: roughly 10,000 additives are estimated to be in the US food supply, with only a fraction independently reviewed.
The consequence for consumers is direct: an additive banned in Paris or Berlin may still appear in your morning cereal in Atlanta or Chicago.
Titanium dioxide (E171): the most famous EU ban
EU status: Banned in all 27 member states since August 7, 2022 (Commission Regulation (EU) 2022/63). US status: Legal, no restriction on quantity.
Why the EU banned it
In May 2021, the EFSA Panel on Food Additives and Flavourings (FAF) published its scientific opinion concluding that E171 can no longer be considered safe as a food additive. The reason: genotoxicity concerns related to titanium dioxide nanoparticles, which can accumulate in tissues and cause DNA damage that may not be reversible.
The opinion drew on more than 200 studies, including INRAE research (Bettini et al., 2017, Scientific Reports) showing that chronic exposure to E171 in rats triggered preneoplastic colon lesions.
Where it still appears in US food
- Candies and gum: Skittles, Starburst, Trident, Mentos (white-coated versions)
- Frostings and icings: Betty Crocker, Pillsbury ready-to-spread varieties
- Coffee creamers (some non-dairy brands)
- Chewing gums (Wrigley, Hubba Bubba)
- Pharmaceutical coatings (legal in both EU and US for medication, controversial)
In July 2022, a class-action lawsuit (Thames v. Mars Inc.) was filed in California over titanium dioxide in Skittles. Mars settled in 2023 without admitting liability and pledged a gradual phase-out, still incomplete in 2026.
BHA (E320) and BHT (E321): the "preservative twins"
EU status: Restricted to specific food categories at very low levels under Regulation (EC) No 1333/2008. Banned in most processed foods. US status: GRAS, used widely as a preservative.
The science
Butylated hydroxyanisole (BHA) is classified by the International Agency for Research on Cancer (IARC) as Group 2B: "possibly carcinogenic to humans" (1986 monograph, reaffirmed 2020). Butylated hydroxytoluene (BHT) has shown endocrine-disrupting activity in animal models (NIH, National Toxicology Program, 2014).
The US National Institutes of Health lists BHA in the 15th Report on Carcinogens (2021) as "reasonably anticipated to be a human carcinogen" based on sufficient evidence from animal studies.
Yet the FDA continues to permit BHA and BHT in:
- Breakfast cereals (Frosted Flakes, Lucky Charms in some batches)
- Chewing gum base
- Processed meats
- Dehydrated potato products
- Vegetable oils and shortenings
The California Office of Environmental Health Hazard Assessment (OEHHA) added BHA to its Proposition 65 list of carcinogens in 1990, requiring warning labels in California. Federal regulation, however, remains unchanged.
Brominated vegetable oil (BVO): the citrus soda additive
EU status: Banned since the 1970s. US status: Banned by the FDA in August 2024, with a 1-year compliance grace period ending August 2025.
What it does and why it is dangerous
BVO is a vegetable oil (typically soybean or corn) modified with bromine atoms to make it denser and able to keep citrus flavor oils suspended in soft drinks. The problem: bromine accumulates in human adipose tissue, and case studies (Horowitz, NEJM, 1997) reported bromism (memory loss, skin lesions, neurological symptoms) in heavy consumers of BVO-containing sodas.
A National Toxicology Program study (2022) confirmed that BVO causes thyroid disruption in rats at doses approximating dietary exposure in heavy soda drinkers.
Where it lingered until recently
- Mountain Dew (PepsiCo removed it in 2020)
- Sun Drop (still contained BVO in 2023)
- Generic citrus sodas from regional bottlers
- Some sports drinks (older formulations)
Although the FDA finally acted in 2024, the EU banned BVO five decades earlier. The lag is emblematic of the GRAS framework's inertia.
Red 3 (Erythrosine, E127): the cherry-pink dye
EU status: Banned in food except for a narrow list (cocktail cherries, candied cherries) since 1994. Banned in cosmetics. US status: Banned by the FDA from food on January 15, 2025, with manufacturers required to comply by January 15, 2027.
The decades-long delay
The FDA officially recognized Red 3 as a carcinogen in 1990, when it banned the dye in cosmetics and externally applied drugs. Why did it remain in food for 35 more years?
The answer lies in the Delaney Clause (1958), which mandates that no carcinogenic additive be approved. The FDA had legal authority to remove Red 3 from food in 1990 but chose not to, citing "low risk at dietary exposure levels." The 2025 decision came after a petition filed by 24 consumer health groups in 2022, including the Center for Science in the Public Interest (CSPI).
Where Red 3 still appears in 2026
- Candies: Brach's Conversation Hearts, Pez, certain Jelly Belly flavors
- Maraschino cherries (most US brands)
- Strawberry milkshake mixes
- Pink frostings and sprinkles
- Some children's medications (still legal in pharmaceuticals)
In Europe, Red 3 was replaced decades ago by alternatives like Carmine (E120) or Beet juice extract (E162).
Potassium bromate (E924): the bread flour additive
EU status: Banned since 1990 (Directive 95/2/EC). US status: Legal at federal level. Banned only in California (2024) and New York (proposed for 2026).
The cancer link
Potassium bromate is used to strengthen dough and improve bread volume. It oxidizes flour proteins for stronger gluten networks. The problem: residual bromate in baked goods, even at trace levels, is classified by IARC as Group 2B (possibly carcinogenic), and has shown tumor formation in rat kidneys (NTP, 1992).
The UK banned it in 1990, the EU followed, and Canada, Brazil, China, India, Peru, Nigeria and Sri Lanka all prohibit it. The FDA has refused to ban it federally for over 30 years, citing the manufacturing argument that "properly baked bread contains undetectable residues."
Where it appears in US food
- Industrial bread brands (some Wonder Bread, Sara Lee batches before California ban)
- Pizza dough at chain restaurants
- Bagels and rolls from large bakeries
- Tortillas (some brands)
The California Food Safety Act (AB 418), signed in October 2023 and effective January 2027, bans potassium bromate, propylparaben, Red 3 and brominated vegetable oil statewide. This sub-federal patchwork is creating a confusing reality for US consumers.
Azodicarbonamide (E927a): the "yoga mat chemical"
EU status: Banned in food since 2005 (Directive 2004/45/EC). Approved only for non-food plastics. US status: Legal, used as a flour bleaching and dough conditioning agent.
Azodicarbonamide earned its nickname in 2014 when a Subway petition revealed it was used both in their bread and in yoga mats and shoe soles. Subway removed it after public pressure, but Pillsbury, McDonald's buns, Wonder Bread and Arby's bread all continued using it at the time.
The World Health Organization (WHO) issued a 1999 statement linking ADA exposure to respiratory issues, including asthma, in bakery workers. The breakdown products semicarbazide and biurea are classified as possible carcinogens.
Propylparaben (E216): the preservative
EU status: Banned in food since 2006. US status: GRAS, used in baked goods and tortillas.
Propylparaben is an endocrine disruptor with documented estrogenic activity (EFSA, 2004 opinion). The EU pulled it after the Soni et al. study (2002) demonstrated reproductive toxicity in rats. In the US, it is still found in:
- Industrial baked goods (some tortilla brands)
- Cake mixes
- Frostings
California's AB 418 also bans propylparaben starting 2027.
Recombinant bovine growth hormone (rBGH/rBST)
EU status: Banned since 2000 (Council Decision 1999/879/EC). US status: Legal, approved by FDA in 1993.
This is technically not an E-number, but it qualifies as a regulatory mismatch. Recombinant bovine somatotropin (rBST), marketed as Posilac by Monsanto and later Elanco, is injected into US dairy cows to boost milk production by 10 to 15%.
The EU banned it citing animal welfare (increased mastitis, lameness) and concerns about elevated IGF-1 levels in milk, which the IARC and several studies have linked to colorectal and breast cancer risk (Renehan et al., Lancet 2004).
In the US, Canada, Australia, New Zealand and Japan have also banned rBGH. Most major US dairy producers have voluntarily phased it out, but it remains legal and is still used in some industrial-scale dairies.

What this means for European consumers buying US products
If you live in the EU and order US food products online (Amazon, iHerb, expat groceries), check labels carefully. Regulation (EC) No 1169/2011 on food information requires that any product sold in the EU comply with EU additive rules, but imports through third-party sellers can slip through enforcement gaps.
The Rapid Alert System for Food and Feed (RASFF) publishes weekly notifications of non-compliant imports. In 2023, 412 notifications concerned unauthorized additives in food imported from non-EU countries (RASFF Annual Report 2023).
For US consumers traveling or living in Europe, the reverse situation is often a positive surprise: European versions of the same brand often have cleaner ingredient lists. The classic example is Heinz Ketchup: the US version contains high-fructose corn syrup, the EU version uses regular sugar.
FAQ
Is the FDA "behind" the EU on additive safety?
Yes and no. The FDA has more rigorous testing requirements for new pharmaceuticals than the EU. But for food additives, the GRAS self-certification system creates structural delays. The EU's precautionary principle results in earlier bans when evidence accumulates.
Are all "banned in Europe" social media claims accurate?
No. Many viral posts conflate "restricted" with "banned" or cite outdated regulations. Always check EFSA opinions and Commission Regulations directly. NutriDecrypte cross-references claims against 13 official sources.
Can I get titanium dioxide in pharmaceutical products in Europe?
Yes. E171 remains authorized for medicinal use under EMA (European Medicines Agency) rules until pharmaceutical alternatives are validated. The EMA published a 2021 review acknowledging the EFSA opinion but maintaining the authorization pending pharmaceutical reformulation.
Are organic US products free of these banned additives?
The USDA Organic standard prohibits most synthetic additives, including artificial colors, BHA, BHT and azodicarbonamide. However, USDA Organic does not specifically address titanium dioxide or rBGH (the latter is excluded by default since growth hormones are banned in organic dairy).
How do I check a product fast?
Scan the barcode with NutriDecrypte. The app cross-references 230+ data points across EFSA, ANSES, FDA and IARC databases and flags any additive banned in the EU even if the product is sold elsewhere.
Conclusion: the regulatory gap is real but closing
The EU-US gap on food additives is narrower than it was a decade ago. The FDA's 2024 BVO ban and 2025 Red 3 ban suggest a slow shift toward precaution. California's AB 418 is pulling national brands toward EU-style standards because manufacturers rarely produce separate formulations for one state.
That said, dozens of additives still legal in the US would never pass EFSA scrutiny today. If you split your time between continents, or simply want to know what your transatlantic relatives are eating, the gap matters.
NutriDecrypte provides free, independent label analysis for products sold in France, the EU, the UK and the US. The app reads each label, identifies banned or restricted additives across all jurisdictions, and gives you a transparent rating based on 13 official scientific sources. No paid placements, no sponsored brands, no marketing influence: just the science, in your pocket.
