The use of artificial food dyes has been a subject of debate for decades, with increasing concerns about their impact on human health. Among the most controversial are Red Dye 3 and Red Dye 40. While these synthetic dyes are widely used in food, beverages, and medications, recent actions by the Food and Drug Administration (FDA) have reignited discussions about their safety and prevalence.
What Is Red Dye 3, and Why Was It Banned?
Red Dye 3, also known as erythrosine or FD&C Red No. 3, is a synthetic color additive derived from petroleum. It has been used to give foods and beverages a bright, cherry-red hue. Historically, Red Dye 3 was approved for use in a variety of products, including candies, baked goods, and oral medications. However, concerns over its safety have grown over the years.
In the 1990s, the FDA banned this Dye from cosmetics and non-oral medications after studies showed it caused cancer in laboratory rats. Despite these findings, the dye remained approved for use in food and beverages—until now. As of 2027, manufacturers will be required to remove Red Dye 3 from all food products, with drugmakers following suit by 2028.
What Foods Have Red Dye 3 in Them?
Red Dye 3 is commonly found in foods that are bright red or pink. Below is a list of popular products that may contain this additive:
Candies
- Brach’s Conversation Hearts: A Valentine’s Day staple.
- Jelly Belly Candy Corn: Known for its colorful appeal.
Baked Goods and Snacks
- Betty Crocker Decorating Icing: Often used for festive cakes and cookies.
- Angela Marie’s Crispy Marshmallow Goodies: Found on platforms like Instacart.
- King’s Rainbow Sprinkle Cookies: Frequently spotted in bakeries.
Other Foods
- Walmart’s Marshmallow Mini Bites: Available during seasonal holidays.
- The Original Crumbs Bakeshop Gourmet Cupcakes: Known for their vibrant frosting.
Consumers can verify whether a product contains this Dye by checking its ingredient list or consulting the U.S. Department of Agriculture’s branded food database.

What Common Foods Have Red Dye 3?
Beyond the specific brands mentioned above, this dye often appears in:
- Frozen desserts: Popsicles and ice creams with red or pink swirls.
- Icing and frosting: Used for birthday cakes and cupcakes.
- Gummies and fruit snacks: Particularly in cherry or strawberry flavors.
Shoppers should remain vigilant and read labels carefully, especially when purchasing brightly colored or seasonal products.
Why Is Red Dye 3 Bad?
The primary concern with this dye is its potential to cause cancer. Studies have shown that high levels of the dye led to thyroid cancer in male laboratory rats. While similar effects have not been conclusively observed in humans, these findings prompted regulatory changes.
Additionally, Red Dye 3 has been linked to behavioral issues in children. Research suggests that artificial dyes, including Red Dye 3, may exacerbate hyperactivity and attention deficits in susceptible children. Although the FDA found no causal relationship in a 2011 investigation, consumer advocacy groups continue to push for stricter regulations.
What Is the Difference Between Red Dye 3 and Red Dye 40?
Both Red Dye 3 and Red Dye 40 are synthetic color additives derived from petroleum, but they differ in their chemical composition and applications.
Dye 3
- Primary Use: Candies, frostings, and baked goods.
- Health Concerns: Linked to cancer in animals and potential behavioral effects in children.
- Banned Uses: Cosmetics and non-oral medications since the 1990s; food products by 2027.
Red Dye 40
- Primary Use: Found in a broader range of products, including condiments, snacks, and beverages.
- Health Concerns: Some studies suggest a potential link to hyperactivity in children and carcinogenicity in animals.
- Regulatory Status: Still widely approved for use in the U.S., but banned in some European countries.
Is Red Dye 40 Banned in the U.S.?
No, Red Dye 40 remains approved for use by the FDA. It is the most commonly used synthetic dye in the U.S., appearing in over 36,000 food products. However, it faces scrutiny from food safety advocates who argue for stricter evaluations and potential bans.
Why Did the FDA Ban Red Dye 3?
The decision to ban this dye stemmed from mounting evidence of its carcinogenic effects in animals. The FDA’s action aligns with a clause in the Federal Food, Drug, and Cosmetic Act prohibiting the approval of color additives found to induce cancer in humans or animals. While human exposure levels are significantly lower than those tested in animals, the risk prompted regulatory action.
What’s Next for Food Manufacturers?
Food manufacturers have until January 15, 2027, to remove this Dye 3 from their products. In the meantime, consumers are encouraged to stay informed and prioritize natural alternatives whenever possible. Companies are likely to reformulate their products using safer, less controversial dyes, such as beetroot powder or carmine.
