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 .

The U.S. on Wednesday banned the use of a synthetic food dye that gives some candies, cakes and certain oral medications a cherry-red color, following evidence that the dye causes cancer in laboratory rats.

FDA’s ban on Red 3 is a shot across the bow to the food sector that could ironically help facilitate Kennedy’s pursuit of further changes.
