How food brands and drugmakers are responding to FDA's ban of food dye Red 3

Companies say they are working to update their products to comply with the Food and Drug Administration's decision Wednesday to ban the artificial food dye Red 3, after the agency said it was revoking the additive's authorization over concerns it was causing cancer in rats.

While the agency says that studies show the way Red 3 causes cancer in rats does not occur in humans, the law still requires additives that cause cancer in animals to be pulled from the market even if they are not proven to pose a risk to humans as well.

The FDA says that food companies will have until Jan. 15, 2027 to stop using the dye. Drugmakers will have an extra year, until January 2028, to comply with the change.
