The FDA revoked the authorization of FD&C Red No. 3 in food and ingested drugs on January 15, 2025, citing a legal mandate to ban colorants linked to cancer in animals — the dye caused thyroid tumors in laboratory rats, per the agency's own order. Food manufacturers have until January 15, 2027 to reformulate; ingested drugs have until January 18, 2028. The dye appears in roughly 1 in 10 food categories — chiefly candies, frostings, and some beverages and snack foods, per the FDA's announcement.

Why now, if the evidence is old?
The rat studies date to the 1980s — Red No. 3 was banned from cosmetics in 1990 under the same legal clause. The mechanism is specific: a threshold dose below which no effect was observed, and typical human exposure estimated far below that threshold, which is why the agency didn't act on food earlier, per the FDA's technical explanation. The 2025 order follows a 2022 citizen petition and settles the decades-long gap between the two standards.
What changes for shoppers?
Less than the headlines suggest, at least at first. Products will mostly switch to other approved colorants — Red No. 40 is the common replacement — so the shelf looks nearly identical in 2027. California's own state-level ban, passed in 2023, already forced some national reformulations ahead of the federal order.
The overlooked detail: the ingested-drug deadline of 2028 matters more than the food one. Some oral medications use the dye for identification, and reformulating drugs is slower — check with a pharmacist rather than assuming a prescription changed, since both old and new formulations will be legal during the transition.
The bottom line
Red No. 3 was banned on a decades-old animal-cancer legal trigger, not a new human-risk finding — per the FDA's own January 2025 order. Expect reformulated candies by 2027, not empty shelves; if a medication's color changes, that's the reason.
