• The FDA has officially banned Red 3 dye in the U.S. food supply due to cancer risks, with the ban taking full effect by January 2027 for food and January 2028 for ingested drugs.
• The decision follows decades of advocacy, citing studies linking Red 3 to cancer in lab rats and concerns over its use in foods consumed by children.
• Manufacturers are transitioning to natural color alternatives like beet juice, red cabbage pigments, and carmine, while the decision may face legal challenges from food producers.

U.S. health regulators announced Wednesday that the Food and Drug Administration (FDA) has officially banned the use of Red 3 dye, also known as FD&C Red No. 3 or erythrosine, in the nation’s food supply. This decision comes nearly 35 years after the dye was prohibited in cosmetics due to cancer risks. The ban will take full effect by January 2027 for food products and January 2028 for ingested drugs, giving manufacturers time to comply.

The FDA cited studies indicating that Red 3 causes cancer in lab rats, triggering the action under the Delaney Clause, a statute requiring the agency to prohibit additives linked to cancer in humans or animals. However, FDA officials clarified that the mechanisms causing cancer in rats do not apply to humans.

What Prompted the Ban?

The FDA’s decision follows a petition filed in 2022 by over two dozen food safety and health advocates, including the Center for Science in the Public Interest (CSPI). Advocates argued that Red 3’s continued use in food created a “double standard,” barring the dye in lipstick while allowing it in candies and snack cakes consumed by children. Further pressure emerged in November 2022, when nearly two dozen members of Congress urged the FDA to act swiftly, citing the Delaney Clause and concerns about children’s higher exposure to the dye.

Dr. Peter Lurie, CSPI director and leader of the petition, welcomed the FDA’s decision, calling it “long overdue.” He emphasized that no aesthetic justification, like bright red food coloring, should outweigh potential health risks.

Impacts on Food and Drug Manufacturers

The ban removes Red 3 from the list of approved color additives for food, dietary supplements, and oral medicines, such as cough syrups. Food companies have until January 2027 to phase out the dye, while drug manufacturers have an additional year. Although Red 3 is still permitted in some countries, products imported into the U.S. must meet the updated regulations.

Some food manufacturers have already begun reformulating their products to eliminate Red 3. Alternatives include natural color sources like beet juice, pigments from purple sweet potato and red cabbage, or carmine, a dye derived from insects.

Despite the FDA’s ruling, the International Association of Color Manufacturers defends the dye’s safety. They point to research by United Nations and World Health Organization committees, including a 2018 review affirming Red 3’s safety when consumed at typical levels.

Legal and Scientific Challenges Ahead

Although the FDA’s ban satisfies health advocates, legal challenges may arise from food manufacturers. FDA Commissioner Dr. Robert Califf warned during a December 2022 hearing that the agency must ensure its scientific evidence holds up in court. Without sufficient data proving the dye’s cancer risk to humans, the FDA could face difficulties defending the ban.

The controversy over Red 3 stems from its complex history. In 1990, the FDA removed authorization for the dye in cosmetics and topical drugs after studies linked it to cancer in rats. However, the agency did not extend the ban to food at the time, as research suggested the cancer-causing mechanisms observed in rats did not apply to humans. For decades, health advocates have urged the FDA to reconsider its stance, ultimately leading to the current ban.

Global and Local Perspectives

Internationally, Red 3 has faced restrictions in Europe, Australia, and New Zealand, where it is banned in most foods except select cherries. Meanwhile, U.S. states like California have already introduced similar bans, with California’s restrictions taking effect in January 2027. Lawmakers in Tennessee, Arkansas, and Indiana have also proposed limiting the use of artificial dyes, particularly in foods served in public schools.

Next Steps and Transition for Consumers

For consumers, the removal of Red 3 could bring noticeable changes to the appearance of some foods. However, many companies have already adopted natural alternatives, which are gaining popularity for their cleaner labels and reduced health concerns. With the transition period in place, industry compliance and consumer awareness will be key to ensuring a smooth shift away from artificial dyes.
