The state of California banned the Red No. 3 dye and three other food additives in 2023, which gave manufacturers until 2027 to change their recipes. Then in 2024, California once again banned six more artificial dyes -- Blue 1, Blue 2, Green 3, Red 40, Yellow 5 and Yellow 6 -- from being served in public schools.

The U.S. Food and Drug Administration banned the dye known as Red 3 from the nation’s food supply in January, setting deadlines for stripping the brightly hued additive from candies and cough syrup, baked goods and frozen treats.

Do you still have candy hearts from Valentine’s Day that say “I love you”? Odds are, red dye No. 3 was used in the manufacturing process. The FDA has officially banned it. KYW medical editor Dr. Brian McDonough looks at what this means to all of us.
