The United States permits a number of food additives, animal drugs, pesticides and processing practices that are banned, restricted or subject to warning labels elsewhere, most often in the European Union. Part of the difference is legal design. EU general food law (Regulation (EC) No 178/2002, Article 7) writes in a precautionary principle that allows provisional restrictions when harmful effects on health are possible but scientific uncertainty persists. US law also requires pre-market approval for new food additives, but substances that companies determine to be “generally recognized as safe” (GRAS) can enter food without FDA review, and withdrawing an existing approval has often taken decades — brominated vegetable oil, for example, was used under an “interim” authorization from 1970 until FDA revoked it in 2024.

The list keeps changing. Since 2023 FDA has removed partially hydrogenated oils from its regulations (2023), revoked brominated vegetable oil (2024), FD&C Red No. 3 (ordered January 2025, effective in food January 2027) and Orange B (2026), proposed revoking Citrus Red No. 2 (2026), opened post-market safety reviews of BHA and azodicarbonamide (2026), and proposed requiring companies to notify it of GRAS determinations (August 2026). Each entry below gives the status as of October 2026; the regulatory documents and studies are listed under Key Research Papers.

The Precautionary Principle and the US Approach

Much of the difference between US and EU outcomes comes from how the two systems are designed.

The EU Precautionary Principle

EU general food law (Regulation (EC) No 178/2002, Article 7) allows provisional risk-management measures when the possibility of harmful effects on health has been identified but scientific uncertainty persists; the principle also appears in Article 191 of the Treaty on the Functioning of the European Union. In practice:

The US Approach

US law (the 1958 Food Additives Amendment) also requires pre-market approval for new food additives, under a “reasonable certainty of no harm” standard. The differences critics point to lie elsewhere:

These regulatory differences are covered in more detail in US vs EU Food Safety Regulation Compared.

Labels, Standards and State Laws

The Bottom Line

US and EU rules differ less in whether new additives need approval than in how GRAS substances are handled, how readily existing approvals are re-examined, and how much scientific uncertainty is enough to act on. Several substances on this page have changed status in the US since 2023: partially hydrogenated oils (removed from the regulations, 2023), brominated vegetable oil (revoked, 2024), Red No. 3 (revoked, effective in food January 2027) and Orange B (revoked, 2026). BHA and azodicarbonamide are under FDA post-market review, and potassium bromate, titanium dioxide, rbST, ractopamine, chlorine-based poultry rinses, atrazine and olestra remain permitted as of October 2026.

For several of these substances the evidence of harm comes from animal studies or occupational exposure, and regulators have weighed the same data differently. Questions about individual health conditions belong with a clinician.
