The federal government's recent decision to ban FD&C Red No. 3 is a landmark event in US food safety, but it is not the first time a color additive has been removed from the food supply. This article delves into the specific dye banned, the regulatory process behind it, and explores other historical and potential future bans.
The Historic Ban on FD&C Red No. 3
A Long-Awaited Federal Action
For decades, consumer advocacy groups pressured the Food and Drug Administration (FDA) to take action against FD&C Red No. 3, also known as Erythrosine or E127. While the FDA had already banned the dye from cosmetics and externally applied drugs in 1990, its use in food, beverages, and ingested medications continued. The nationwide ban, announced in January 2025, finally resolved this regulatory paradox. Manufacturers must now reformulate their products to remove Red No. 3 by early 2027, with a slightly extended deadline for drug manufacturers.
The Scientific Rationale and the Delaney Clause
The FDA’s decision was mandated by the Delaney Clause, a provision of the 1958 Federal Food, Drug, and Cosmetic Act. This law requires the FDA to prohibit the use of any food or color additive found to induce cancer in humans or animals, regardless of the dosage. In the 1980s, animal studies revealed that high levels of Red No. 3 caused thyroid cancer in rats. Although the FDA noted the mechanism of cancer in rats might not occur in humans, the Delaney Clause compelled the ban.
A State-Level Precursor
Before the federal ruling, several states had already moved to regulate or ban certain additives. In 2023, California became the first state to pass a law banning Red No. 3 and three other additives, with the ban taking effect in 2027. This decisive state action intensified pressure on the FDA to address the issue at a national level, a pattern observed in other food safety debates.
Other Noteworthy Banned Food Dyes in US History
Red No. 3 is part of a longer history of dyes being banned in the US due to safety concerns. Other notable bans include:
- FD&C Red No. 2 (Amaranth): Banned in 1976 amid controversy. Although FDA studies were inconclusive regarding a cancer link, public anxiety and advocacy led to its removal from the approved list for food additives. For nearly a decade, some companies like Mars even removed red M&M's to avoid consumer confusion, though they had never used Red 2.
- FD&C Violet No. 1: Banned in 1973 after studies linked it to cancer in laboratory animals. It had been used to stamp inspection marks on meat.
- Early 20th-Century Bans: A number of older, sometimes crude, dyes were banned much earlier. For example, Orange 1, which caused gastrointestinal issues in children, was banned in 1956.
How Dyes Get Banned: The Regulatory Process
The Delaney Clause's Influence
The Delaney Clause fundamentally shaped how the FDA handles potentially carcinogenic additives. Unlike other risk assessments where dosage and exposure levels are considered, the Delaney Clause operates on an all-or-nothing principle: if a substance causes cancer in animals, it must be banned from food. This was the driving force behind the Red No. 3 ban, even as some argued the risk to humans was negligible.
Comparing US and European Approaches
Regulation of food dyes differs significantly between the US and Europe. The EU often adopts a more precautionary principle, placing the burden of proof on manufacturers to demonstrate absolute safety. This has led to certain dyes, still approved in the US, being banned or requiring a warning label in Europe.
A Tale of Two Regulatory Approaches
| Feature | US (FDA) | European Union (EFSA) |
|---|---|---|
| Regulatory Principle | Generally relies on risk assessment; exceptions like the Delaney Clause enforce stricter rules. | More precautionary; if a risk is identified, the substance may be banned or restricted even without definitive proof of harm. |
| Red No. 3 | Banned for food and ingested drugs nationwide in 2025. | Restricted since 1994, with very limited use, mainly for candied cherries. |
| Other Common Dyes | Dyes like Red 40, Yellow 5, and Yellow 6 are certified and allowed. | Dyes like Red 40, Yellow 5, and Yellow 6 require a warning label about potential effects on children's behavior. |
Reading Labels and Making Informed Choices
For consumers, staying informed about what is in their food is critical. As manufacturers phase out Red No. 3, ingredient labels should be carefully checked. Look for “FD&C Red No. 3” or “Erythrosine” on products like icings, candies, and maraschino cherries. The move toward natural colorants is gaining traction, with many companies adopting alternatives like beet juice or turmeric to color products.
Conclusion
The ban on FD&C Red No. 3 marks the latest chapter in the ongoing history of regulating color additives to protect public health. While the dye was found to cause cancer in animals, the ban highlights the lasting impact of consumer advocacy and the strict, though sometimes slow, enforcement of regulations like the Delaney Clause. For consumers, this action serves as a crucial reminder to read ingredient lists and supports the broader shift towards more natural and transparent food ingredients. The dynamic between federal regulations, state-level initiatives, and evolving science ensures that food safety remains a central and ongoing public conversation.

The Move Toward Natural Alternatives
Many food manufacturers are voluntarily moving away from artificial colors, a trend accelerated by both regulation and consumer demand. Some companies have announced plans to eliminate synthetic dyes entirely, favoring options like beet, turmeric, and paprika for vibrant coloring. This shift not only eliminates potentially controversial additives but also addresses consumer preferences for products perceived as more natural and wholesome.
The Ongoing Debate Over Remaining Dyes
It is important to note that the debate over food dyes is far from over. Dyes like FD&C Red No. 40, Yellow No. 5, and Yellow No. 6 remain a subject of scrutiny, particularly regarding potential links to neurobehavioral issues in some children. Although the FDA currently permits their use, state-level actions and ongoing consumer pressure may lead to further federal re-evaluation in the future.
