Red No. 3 (Erythrosine): FDA Ban, Deadlines & What Companies Must Do

What Is Red No. 3?

FD&C Red No. 3, known chemically as erythrosine (CAS 16423-68-0, UNII: PN2ZH5LOQY), is a synthetic coal-tar dye that produces a characteristic cherry-red color in food, drugs, and — until 1990 — cosmetics. It is a fluorone dye, structurally an iodinated form of fluorescein, and has been used as a color additive in the United States since 1907, permanently listed by the FDA in 1969.

Red No. 3 is distinct from FD&C Red No. 40 (Allura Red), which is a different azo dye with separate regulatory treatment. The two are frequently confused in industry discussions. Red No. 3 also exists as an aluminum lake form (FD&C Red No. 3 aluminum lake, UNII: WXF83K327F), which was terminated for all uses effective January 29, 1990.

Red No. 3 has historically appeared in products where a bright, non-bleeding red is needed — maraschino cherries, candy hearts, cake decorations, and certain oral medications. Its use in cosmetics and externally applied drugs was banned in 1990 under the Delaney Clause after studies demonstrated thyroid carcinogenicity in male rats. For 35 years, the dye remained legal in food and ingested drugs despite the identical evidence base — an anomaly that regulators, advocacy groups, and the Center for Science in the Public Interest (CSPI) challenged repeatedly.

That anomaly ended on January 15, 2025.

FDA Regulatory Status

Red No. 3 is banned in food and ingested drugs in the United States. The FDA issued a final order on January 15, 2025, revoking the color additive listings at 21 CFR 74.303 (food use) and 21 CFR 74.1303 (drug use). The order was published in the Federal Register at 90 FR 4628 (January 16, 2025), under docket FDA-2023-N-0437.

The revocation was triggered by a color additive petition filed by CSPI and 22 co-petitioners, which presented evidence that FD&C Red No. 3 induces thyroid tumors in male laboratory rats. Under the Delaney Clause — Section 721(b)(5)(B) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), enacted as part of the 1960 Color Additives Amendment — the FDA is prohibited from listing any color additive found to induce cancer in humans or animals. The clause operates as a strict legal mandate: once the cancer finding is established, the FDA has no discretion to conduct a risk-benefit analysis or set a safe threshold.

The FDA explicitly acknowledged that the mechanism of carcinogenicity (thyroid hormone disruption in male rats) does not occur in humans at typical exposure levels. However, the Delaney Clause does not permit a human-relevance exception. The agency stated it was revoking the listing "as a matter of law."

Historical Timeline

Date	Action
1907	FD&C Red No. 3 first listed as a permitted color additive
1969	Red No. 3 permanently listed for food, drug, and cosmetic use (34 FR 7446)
1990	FDA terminates provisional listing for cosmetics and external drugs; lakes cancelled for all uses
2008	CSPI files citizen petition (FDA-2008-P-0349) requesting ban on all eight artificial food dyes, including Red No. 3
October 2022	CSPI and co-petitioners file formal color additive petition
January 15, 2025	FDA issues final order revoking 21 CFR 74.303 and 74.1303
February 18, 2025	Deadline for objections and hearing requests
April 22, 2025	FDA/HHS announce broader phase-out of all six remaining petroleum-based synthetic food dyes by end of 2026

Key Deadlines

Companies currently using Red No. 3 face two hard compliance deadlines. These are not voluntary — products containing FD&C Red No. 3 will be adulterated under the FD&C Act after these dates.

Deadline	Scope	CFR Section
January 15, 2027	All food products, including dietary supplements	21 CFR 74.303 (removed)
January 18, 2028	All ingested drugs (Rx and OTC)	21 CFR 74.1303 (revised, then removed)

The FDA has also publicly urged companies to remove Red No. 3 ahead of the 2027 food deadline, as part of the broader MAHA (Make America Healthy Again) initiative to eliminate all petroleum-based synthetic dyes from the food supply by end of 2026.

For pharmaceutical companies, the extended timeline to January 2028 reflects the longer reformulation and regulatory resubmission cycle for drug products, including stability testing and supplemental NDA/ANDA filings.

Accelerated voluntary timeline: On April 22, 2025, the FDA and HHS announced a plan to phase out petroleum-based synthetic dyes from the U.S. food supply. The announcement covered eight dyes total: six for voluntary industry phase-out by end of 2026 (Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2, and Green No. 3) plus formal revocation proceedings for two rarely-used dyes (Citrus Red No. 2 and Orange B). As part of this initiative, FDA is also requesting that food companies remove Red No. 3 sooner than the January 2027 statutory deadline.

State-Level Bans

The federal ban does not exist in isolation. Red No. 3 is also subject to state-level restrictions that in some cases are broader, earlier, or carry different enforcement mechanisms.

California — AB 418 (California Food Safety Act)

Signed into law on October 7, 2023, AB 418 prohibits the manufacture, sale, or distribution of any food product in California containing Red No. 3, potassium bromate, propylparaben, or brominated vegetable oil. The law takes effect January 1, 2027 — two weeks before the federal food deadline. California was the first state to enact a targeted food additive ban of this kind.

AB 418 carries civil penalties of up to $5,000 for a first violation and $10,000 for subsequent violations. Enforcement is handled by the California Attorney General and local prosecutors.

California also enacted AB 2316 (2024), which bans foods containing six synthetic dyes (Blue 1, Blue 2, Green 3, Red 40, Yellow 5, Yellow 6) from school food service by December 31, 2027. Red No. 3 is not included in AB 2316 because it is already addressed by AB 418 and the federal ban.

West Virginia — HB 2354

Signed on March 24, 2025, West Virginia's law is the broadest state-level food dye ban enacted to date. It has a split timeline: a school meals ban effective August 1, 2025, and a broader retail food sale ban effective January 1, 2028 prohibiting foods containing Red No. 3, Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2, Green No. 3, BHA, and propylparaben. Note: A federal judge issued a preliminary injunction in December 2025 blocking enforcement of the retail provisions; the school meals ban remains in effect.

Other State Activity

State	Scope	Status
Utah (HB 402)	Bans Red No. 3 and 8 other dyes/additives in school food	Law effective May 7, 2025; school compliance required 2026-27 school year
Arizona (HB 2164)	Bans Red No. 3 and other dyes in school food	Effective 2026-2027 school year
Virginia (S 1289/H 1910)	Bans Red No. 3 and 6 other dyes in school food	Effective July 1, 2027
Illinois	Legislation pending to ban Red No. 3 in consumer food products	Introduced 2025
New York	Legislation pending to ban Red No. 3 in consumer food products	Introduced 2025
Pennsylvania	Legislation pending to ban Red No. 3 and other additives	Introduced 2025

As of early 2026, more than 15 state-level food chemical bills have been enacted, with nearly 70 introduced across state legislatures — a legislative wave accelerated by the MAHA movement and the FDA's own enforcement posture.

Affected Product Categories

Red No. 3 is used across a wide range of food and drug categories. Companies should audit any product line that uses a cherry-red, pink, or strawberry-colored formulation.

Food Products

• Candy and confections — Valentine's Day candy hearts (e.g., Brach's), PEZ fruit assortments, candy corn, gummy candies, fruit-flavored hard candy
• Baked goods — Cake decorations, frostings, icings, strawberry-flavored pastries, snack cakes (Hostess)
• Fruit products — Maraschino cherries, canned fruit cocktail (cherry components), fruit-flavored snacks
• Frozen desserts — Strawberry ice pops, flavored ice cream, frozen yogurt
• Beverages — Strawberry-flavored drinks (Yoo-hoo Strawberry), nutrition shakes, flavored waters
• Dairy products — Strawberry-flavored yogurt, flavored milk
• Cereals and snack foods — Certain fruit-flavored cereals, flavored popcorn

Ingested Drugs

• Cough syrups and liquid medications (cherry/strawberry-flavored)
• Gummy vitamins and chewable supplements
• Coated tablets (red-colored OTC analgesics, antihistamines)
• Oral suspensions

Not Affected

Red No. 3 was already banned in cosmetics and externally applied drugs in 1990. The current revocation does not affect these categories — they were already non-compliant uses.

What Companies Should Do

Immediate Actions (Now Through Q2 2026)

1. Audit your product portfolio. Identify every SKU that lists FD&C Red No. 3, erythrosine, or E127 on its ingredient declaration. Include contract-manufactured products and private-label lines where you control the specification.

2. Check your color additive suppliers. Some color blends contain Red No. 3 as a component. Request current certificates of analysis and confirm whether any blended colorants include erythrosine.

3. Map your state exposure. If you sell into California, your effective deadline is January 1, 2027 under AB 418 — and California's enforcement mechanism (civil penalties) is separate from FDA's. If you sell into school food channels, Utah's ban is already effective as of May 2025.

4. Engage your reformulation team. Natural alternatives include beet juice concentrate, red cabbage extract, carmine (cochineal), and fruit/vegetable juice blends. Each has different stability, pH sensitivity, cost, and allergen profiles (carmine requires allergen disclosure per 21 CFR 73.100). Start stability testing now — reformulation lead times for color changes typically run 6-12 months.

Reformulation Considerations

• Cost: Industry estimates vary widely, but color reformulation typically costs $50,000-$200,000 per SKU when including stability testing, packaging updates, and label reprinting. Companies with large portfolios face multi-million-dollar programs.
• Supply chain: Natural red colorants have experienced supply pressure as demand surges. Secure supply agreements early.
• Labeling: Updated ingredient lists must comply with 21 CFR 101.22. If switching to a color exempt from certification (e.g., beet juice), the declaration changes from "FD&C Red No. 3" to the common name of the new source.
• Consumer messaging: Some companies are using the reformulation as a marketing opportunity, particularly given consumer sentiment driven by MAHA. Consider timing announcements to align with the broader industry movement.

For Pharmaceutical Companies

Drug reformulation carries additional regulatory burden:

• Supplemental NDA/ANDA filings may be required for color changes to approved drugs
• Stability testing under ICH guidelines (typically 6-12 months accelerated, 24 months real-time)
• Bioequivalence is generally not affected by color additive changes, but FDA guidance should be consulted
• The January 18, 2028 deadline provides more runway, but companies should begin now given typical pharmaceutical development timelines

For Companies Selling Internationally

Red No. 3 (E127) remains approved in the EU, though restricted to specific uses (cocktail cherries, candied cherries, bigarreaux cherries). Companies exporting to EU markets can continue using erythrosine in permitted categories. However, global reformulation to a single natural-colorant specification may be more cost-effective than maintaining dual formulations.

Related Enforcement Actions

Policy Canary's regulatory database includes several enforcement actions involving Red No. 3, primarily recalls of food products where the dye was either uncertified or present in non-compliant formulations:

• Walmart cherry mixed fruit — Recalled for containing uncertified color additives
• Shoppers Value fruit cocktail — Recalled for uncertified color additive presence
• Jelly stick products — Multiple import alerts for Red No. 3-related violations
• Puerto Rico-manufactured wedding cake products — Recalled for unapproved colorant usage
• Hawaiian beverages — Recalled for color additive violations

The FDA has also issued guidance on uncertified colors in exported food products, clarifying that while Section 801(e)(1) of the FD&C Act provides certain exemptions for exports, color additive certification requirements remain applicable.

Anticipated Enforcement Posture

Post-January 15, 2027, any food product containing FD&C Red No. 3 will be deemed adulterated under Section 721 of the FD&C Act. The FDA can pursue:

• Warning letters for continued manufacturing or distribution
• Import alerts and detention without physical examination (DWPE) for imported products
• Seizure of adulterated products in interstate commerce
• Injunctions against manufacturers who fail to reformulate

Given the political momentum behind MAHA and the FDA's stated goal of accelerating the removal of all synthetic dyes, enforcement is expected to be aggressive and highly visible. Companies that miss the deadline face not only regulatory risk but significant reputational exposure in an environment where food dye safety is a top-of-mind consumer issue.

Broader Context: The End of Synthetic Food Dyes

The Red No. 3 ban is the first domino in what is shaping up to be a complete phase-out of petroleum-based food dyes in the United States. The FDA's April 2025 announcement targets six certified synthetic food dyes — Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2, and Green 3 — for voluntary elimination by end of 2026, with regulatory action to follow if industry compliance is insufficient. The agency also initiated formal revocation proceedings for two rarely-used dyes, Citrus Red No. 2 and Orange B.

Major food companies have already committed to reformulation timelines:

• General Mills: Synthetic dyes out of cereals and school food by summer 2026; full U.S. portfolio by end of 2027
• Conagra Brands: School foodservice products dye-free by 2026-27 academic year; full U.S. retail by end of 2027
• JM Smucker (Hostess): Began reformulating snack cakes and fruit pies in January 2025; full brand portfolio by end of 2027

Companies still using Red No. 3 should treat this not as an isolated compliance event but as the beginning of a multi-year reformulation program that will eventually touch every synthetic colorant in their portfolio.
