What to know about Red Dye No. 40 and artificial food coloring used in thousands of food and drink products sold in the U.S.
The FDA banned the use of Red Dye No. 3 based on a petition asking that the agency follow a specific guideline.
There is a difference between red dye 3 and red dye 40, and only one of them has been officially banned in the United States.
Earlier this week, the FDS said it's banning the use of Red Dye No. 3 in food, due to its link to cancer in animals.
