While it caused cancer in these male rats, the dye does not cause cancer in humans and other animals in the same way, according to other studies. Therefore, “claims that the use of FD&C Red No. 3 in food and in ingested drugs puts people at risk are not supported by the available scientific information,” according to the FDA.

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 colorant was banned from cosmetics and non-oral medications decades ago because a study showed it caused cancer when eaten by rats. But it kept appearing on the ingredient lists of popular snack foods and other grocery products because it remained approved for use until now.

Red No. 3, also known as erythrosine, is a color additive made from petroleum that gives foods and drinks a bright, cherry-red color.

The FDA’s move comes more than a year after California Gov. Gavin Newsom signed the California Food Safety Act, which bans red dye No. 3 and other substances from being sold in the state.

Federal regulators this week banned a red food dye long considered a carcinogen. Confectioners like Hershey say they haven't used the ingredient in years.

A colorful ingredient you may find in your pantry or medicine cabinet is now banned by the Food and Drug Administration.

From candy and concentrated fruit juice to pickles and ice cream, red dye No. 3 gives thousands of products a bright, cherry-red hue. The U.S. Food and Drug Administration announced a ban on red No. 3 on Jan.

The FDA has officially banned Red 3, a common food coloring dye. The ban came after research found that the dye could cause cancer in rats. This has left many companies and stores wondering what manufacturers plan to do about the ban and what alternatives they’ll use.
