Red Dye 40 Isn't Banned. Here's What's Actually Happening — and the Full Brand Hit List.

Is Red 40 being banned?

No. Red Dye No. 40 is not banned by the FDA, and as of this writing there is no federal rule that prohibits it. What happened in 2025 is different — and the difference matters if you're reading labels.

On April 22, 2025, the U.S. Department of Health and Human Services and the FDA announced an initiative to phase out six petroleum-based synthetic dyes from the food supply by the end of 2026. The critical word is voluntary. The Center for Science in the Public Interest, which has petitioned against these dyes for years, put it bluntly: "the agency is not issuing a ban; instead, the FDA has asked food manufacturers to comply with the agency's request to remove these food dyes voluntarily." CSPI added that the plan rests on "an unspecified 'understanding' with some unspecified fraction of the food industry." No formal agreement was published. No industry representative was at the announcement.

So when a headline tells you Red 40 is "getting banned by 2026," that's marketing the news the way brands market a label. The truth is more useful: there's a target, a pile of corporate pledges, and a couple of state laws doing the real legal work — and the dye is still legal and still in thousands of products right now.

What's the difference between Red 3 and Red 40?

Red No. 3 was actually revoked by the FDA. Red No. 40 was not. People conflate the two constantly, and the brands aren't going to correct you.

On January 15, 2025, the FDA issued an order revoking the authorization for FD&C Red No. 3 (erythrosine) in food, beverages, and ingested drugs. Manufacturers have until January 15, 2027 to reformulate food and beverages, and ingested-drug makers have until January 18, 2028. The legal trigger was the Delaney Clause — a provision that bars the FDA from authorizing any additive shown to induce cancer in people or animals. The FDA's own language is precise here: there is "no evidence that the use of FD&C Red No. 3 in food or in ingested drugs puts people at risk," but a 2022 color-additive petition showed high doses caused cancer in male lab rats. Under Delaney, that finding leaves the agency no discretion. Revocation was mandatory.

Red 40 (Allura Red AC) carries no such cancer finding and no Delaney revocation. That's why it sits in the voluntary bucket, not the banned one. Same color family, completely different legal status.

Why are synthetic dyes being phased out at all?

The stated reason is a body of research suggesting a link between synthetic dyes and behavior in some children — a contested area, not a closed case. We'll quote the regulators and researchers and let you weigh it.

CSPI's position, drawn from decades of studies it cites, is that the most widely used synthetic dyes "can cause or exacerbate neurobehavioral problems in some children," and that those problems "can make it harder for affected kids to succeed in school and socially." California's Office of Environmental Health Hazard Assessment reached a similar conclusion in its 2021 review of the evidence on dyes and childhood hyperactivity and inattention. The food-color industry disputes the strength of that link, and the FDA has not concluded that these dyes are unsafe at approved levels — its 2025 move is framed as precaution, with FDA Commissioner Martin Makary citing "growing concerns of doctors and parents."

Our read: this is a "research suggests, regulators are acting cautiously, the science is still being argued" situation. That's exactly the kind of nuance a front-of-package claim flattens — and exactly why the ingredient list, not the headline, is the thing to read.

What state laws actually restrict Red 40?

Two states have passed laws, and they're narrower than most coverage implies — both center on schools, and one has already been partly blocked in court.

California passed two laws. The California Food Safety Act (AB 418) bans Red No. 3, potassium bromate, brominated vegetable oil, and propylparaben statewide, effective January 1, 2027 — note that's Red 3, not Red 40. The California School Food Safety Act (AB 2316) is the one that hits Red 40: it bars Blue 1, Blue 2, Green 3, Red 40, Yellow 5, Yellow 6, and titanium dioxide from foods served or sold in K-12 public schools, effective December 31, 2027.

West Virginia went broader. House Bill 2354 banned seven dyes — including Red 40 and Yellow 5 — in school nutrition programs starting August 1, 2025, with a statewide retail ban (plus BHA and propylparaben) set for January 1, 2028. But in December 2025, U.S. District Judge Irene Berger granted a preliminary injunction blocking the statewide retail ban while a color-manufacturers' lawsuit proceeds. The injunction did not touch the school provisions. So as of this writing, the West Virginia school ban stands; the broader retail ban is on hold.

State laws, not the federal "phase-out," are the only place Red 40 currently faces an actual legal restriction — and only in schools.

Which brands are removing it?

A real list — only brands with verified public commitments, and the dates they gave. Pledges, not a rule, are doing the heavy lifting.

And the brands that have not committed: Coca-Cola, Keurig Dr Pepper, and Ferrero have made no concrete plans, and Mondelez says only that it's "actively working on a transition." CSPI's tracker also notes several companies — including Campbell's, General Mills, Mars, Mondelez, and Kellogg's — have failed earlier dye pledges before, which is exactly why "voluntary" deserves a skeptical eyebrow.

The honest summary: the exodus is real and accelerating, but it's a wave of self-imposed deadlines, not a law. A pledge can slip. A reformulation can apply to new SKUs while the old dyed version stays on the shelf (see: PepsiCo). The product in your hand today is the only thing the ingredient list can't spin.

What foods contain Red 40?

Red 40 shows up most in brightly colored, heavily processed products — and it's always listed by name, near the bottom. That's the tell.

By category, you'll find Red 40 (or "FD&C Red No. 40," or "Allura Red AC") concentrated in candy, sodas and sports drinks, powdered and fruit-punch drink mixes, fruit snacks, flavored chips, many cereals, colored frostings and cake mixes, and flavored dairy like yogurt, pudding, popsicles, and ice cream. It's also in a lot of children's medications. We're naming categories, not asserting any specific product's current formula — because brands reformulate constantly right now, and the label on today's box is the only source of truth. The 2025 dye exodus means the same brand can have a dyed version and a dye-free version on the shelf at the same time.

Here's the pattern that survives any reformulation: synthetic dyes live at the end of the ingredient list, in the smallest type, after everything that sounds wholesome. That placement is legal and intentional. The order is by weight — dyes are a tiny fraction by weight — but the effect is that the thing some shoppers most want to avoid is the last thing they read. We think that's worth flipping.

What should you actually do about it?

Stop waiting for a ban that isn't coming for Red 40, and start reading the bottom of the list. The dyes are still legal, still common, and — for now — still hiding in plain sight on products whose fronts say nothing.

Set Red 40, Yellow 5, or "synthetic dyes" as a sensitivity in your profile, and they'll surface on every scan instead of getting lost in nine-point type. Label Snob scores on what's actually in the product — additives included — not on what the package wants you to feel.
