In January, the U.S. Food and Drug Administration (FDA) banned the use of Red No. 3 in food and ingested drugs. The synthetic dye has been primarily used to produce a bright, cherry color in candy, cakes, cookies, frozen desserts and certain pharmaceuticals. The ruling was prompted by a 2022 petition by the Center for Science in the Public Interest, which demonstrated that the coloring agent caused cancer in male rats exposed to high levels. Manufactures must stop using the dye in foods by January 2027 and in ingestible drugs by January 2028.
