Red Dye No. 3, also known as erythrosine or FD&C Red No. 3, is a synthetic dye derived from petroleum that is used in foods to give them a bright red color. It is banned from use in cosmetics and external drugs, but it is still used in many packaged foods. The FDA recognizes Red Dye No. 3 as a carcinogen, and it has been linked to other health problems such as child behavioral issues and reproductive health decline. Here are some common foods that contain Red Dye No. 3:

• Candy: Candy corn, Hot Tamales, PEZ, Sixlets, Ringpop, Dubble Bubble.
• Baked goods: Betty Crocker Fruit by the Foot, Hostess Ding Dongs, Entenmanns Little Bites.
• Canned fruit: Maraschino cherries.
• Frosting.
• Meal replacement shakes.
• Popsicles.
• Sausage casings.
• Oral medications.

Its important to note that Red Dye No. 3 is not the only synthetic food dye used in foods. Other common food dyes include Red #40, Yellow #5, and Yellow #6.
