A Tale of Two Red Dyes: Understanding the Recent Regulatory Shift
For decades, artificial red colorings have been a staple in the processed food industry, used to enhance the visual appeal of everything from candy to sausages. The FDA's recent ban on Red Dye 3, also known as Erythrosine, marks a significant shift in food safety regulation. This action, prompted by decades-old animal studies and pushed by consumer advocacy groups, gives manufacturers until early 2027 to phase the dye out of their products. In contrast, Red Dye 40, or Allura Red AC, remains a legal and extremely common food additive despite ongoing concerns about its potential links to hyperactivity and behavioral issues in children. This dynamic regulatory landscape means consumers must remain vigilant by checking product labels.
Common Foods Containing Red Dye 3
Although the ban is in effect, products containing Red Dye 3 are likely to remain on shelves for a period as companies work to reformulate. This dye is known for creating a bright, cherry-red color and is often found in items that appeal to children.
Products to inspect for Red Dye 3:
- Maraschino Cherries: Traditionally colored with this dye, though many brands have begun to switch to alternatives like Red Dye 40 or carmine.
- Season-Specific Candies: Many Valentine's Day and Halloween candies, including some conversation hearts and candy corn, historically used Red Dye 3.
- Canned Fruit Products: Certain fruit cocktails or canned fruit medleys have used this coloring.
- Certain Baked Goods and Icings: Some cake and cookie mixes, frostings, and decorating gels contain Red Dye 3.
- Strawberry Milk and Other Flavored Drinks: Some strawberry-flavored milks and other beverages used this additive for color.
- Processed Meats: Bacon bits and some types of sausages have used Red Dye 3.
Common Foods Containing Red Dye 40
Red Dye 40 is the most widely used synthetic food dye in the United States and can be found in a vast array of products, both red and otherwise. Its prevalence means consumers must read labels even for products that don't appear vibrantly red.
Products commonly containing Red Dye 40:
- Cereals: Many popular children's cereals use Red Dye 40.
- Snack Foods: Chips with "hot" or "flaming" flavors, cheese crackers, and certain packaged snacks often contain this dye.
- Beverages: Sodas, sports drinks, and fruit punches are frequent culprits.
- Desserts: Gelatins, puddings, ice cream, and popsicles are common carriers.
- Condiments: Barbecue sauce, some salad dressings, and ketchup brands can contain Red Dye 40.
- Baked Goods: This dye is used in many pastries, cakes, and frostings.
- Candy: A wide variety of candy and gum brands use Red Dye 40.
- Yogurt and Dairy Products: Flavored yogurts often contain this dye.
Comparison Table: Red Dye 3 vs. Red Dye 40
| Feature | Red Dye 3 (Erythrosine) | Red Dye 40 (Allura Red AC) |
|---|---|---|
| Status | Banned in food by FDA (effective 2027) | Widely permitted by FDA |
| Usage | Primarily to create bright, cherry-red color | Used in a broader spectrum for red and other colors |
| Health Concerns | Linked to thyroid cancer in rats | Associated with hyperactivity in sensitive children |
| Prevalence | Declining due to pending ban and reformulation | Most widely used synthetic food coloring |
| Chemical Basis | Iodine-based compound | Petroleum-based synthetic dye |
| Foods Found In | Maraschino cherries, seasonal candies, some frozen desserts | Cereals, sports drinks, chips, many candies, baked goods |
What to look for on ingredient labels
The most effective way to avoid these color additives is to become a savvy label reader. The FDA requires manufacturers to list all ingredients, including color additives, by name. When scanning a product's ingredient list, look for specific terms. For Red Dye 3, the label may list it as "FD&C Red No. 3," "Red 3," or "Erythrosine". For Red Dye 40, you will find it listed as "FD&C Red No. 40," "Red 40," or "Allura Red AC". When possible, opt for whole, unprocessed foods or products that use natural colorings derived from sources like beets, paprika, or carmine. The Center for Science in the Public Interest (CSPI) has long advocated for the removal of all synthetic food dyes and offers extensive resources for consumers.
The Future of Artificial Colors
The FDA's ban on Red Dye 3 signals a potential shift towards greater regulation of artificial colors in the U.S. food supply. California's 2023 law banning Red 3 and other additives provided significant momentum for federal action. Some companies have already voluntarily reformulated products, replacing synthetic dyes with natural colorants to appeal to health-conscious consumers. However, the broader use of Red Dye 40 continues to face scrutiny from consumer groups and some state legislatures, indicating that the conversation about artificial food colors is far from over. For now, being proactive in reading labels remains the most reliable strategy for avoiding these additives.
Conclusion
Navigating the world of food additives requires attention to detail, especially regarding artificial colorings like Red Dye 3 and Red Dye 40. While the impending ban on Red Dye 3 is a win for consumer safety, Red Dye 40 is still ubiquitous in many processed and packaged foods, including items not obviously red. By checking ingredient lists for specific names like "Erythrosine" and "Allura Red AC," consumers can reduce their exposure to these synthetic chemicals. Opting for whole foods and brands that prioritize natural colorings is another effective strategy for managing dietary intake of artificial dyes.
Natural Color Alternatives
Manufacturers have natural options to achieve a red hue. Carmine, derived from cochineal insects, creates a deep red color. Beet juice concentrate is another alternative that provides a reddish-pink color. These natural alternatives, though sometimes more costly or less stable, are increasingly used in response to consumer demand for cleaner labels.
Actionable Steps for Consumers
- Read Labels Carefully: Look for "FD&C Red No. 3" or "Erythrosine" and "FD&C Red No. 40" or "Allura Red AC" on ingredient lists.
- Focus on Whole Foods: Emphasize a diet rich in fresh fruits, vegetables, and unprocessed foods to naturally minimize intake of all artificial additives.
- Use Natural Substitutes: When cooking or baking at home, use beet powder, beet juice, or paprika for natural red coloring.
- Support Reformulated Products: Look for brands that have removed synthetic dyes or have voluntarily transitioned to natural colorings.
- Stay Informed: Follow updates from organizations like the FDA and consumer advocacy groups for the latest information on food additive regulations.
By staying informed and actively checking labels, consumers can confidently choose what goes into their food and advocate for a cleaner food supply.
Frequently Asked Questions
What are Red Dye 3 and Red Dye 40?
Red Dye 3 (Erythrosine) and Red Dye 40 (Allura Red AC) are synthetic, petroleum-based food colorings added to processed foods, beverages, and other consumer products to enhance visual appeal. Red Dye 40 is currently the most widely used food dye in the US.
Why was Red Dye 3 banned by the FDA?

To identify these dyes, look for "FD&C Red No. 3" or "Erythrosine" and "FD&C Red No. 40" or "Allura Red AC" in the ingredients list on product packaging.
What are some natural alternatives to Red Dye 3 and 40?
Natural red food colorings can be derived from plant-based sources, such as beet juice or paprika, or from insects, such as carmine. These are increasingly used by manufacturers seeking to offer products with cleaner labels.
