Red dye No. 3 has been permissible for use in food despite the Delaney Clause of the FDA’s Federal Food, Drug, and Cosmetic Act. The clause, in part, “prohibits the FDA from approving a color additive that is ingested if it causes cancer in animals or humans when ingested,” according to the agency .

U.S. regulators are banning the dye called Red 3 from the food supply. The move comes nearly 35 years after the dye was barred from cosmetics such as lipsticks because of potential cancer risk.
