The U.S. Food and Drug Administration has officially banned the use of red dye No.3 after the knowledge that it can cause cancer in animals — a discovery found more than 30 years ago. 

The synthetic additive, also known scientifically as erythrosine, is most commonly used to give foods and beverages a distinct, bright, cherry-red color and has been a key substance in America’s food system. 

Manufacturers using Red No. 3 in goods and ingested drugs now have until January 15, 2027, and January 18, 2028, respectively, to reformulate their products, as stated by the FDA. 

“Today’s action by FDA is long overdue, is a small step in the right direction, and hopefully signals a renewed effort by FDA to do its job despite the many barriers the food industry places in its way,” wrote Dr. Jerold Mande, adjunct professor of nutrition at the Harvard University T.H. Chan School of Public Health.

Which foods have red dye No. 3?

As per the FDA, the Center for Science in the Public Interest (CSPI) and Amanda Beaver, a dietician at Houston Methodist Hospital, note that a few common foods containing the substance include candy (especially seasonal candies, like candy corn), cakes/cupcakes, frozen strawberry-flavored desserts, fruit cocktails, sausages, frosting, and bacon bits — among others. 

Dr. Peter Lurie, the president and executive director of CSPI, additionally told TODAY.com that noticeable oral medicines such as acetaminophen, a pain reliever, and fluoxetine, an antidepressant, may have traces of Red No.3. 

But while this ban is fresh news, it appears the substance has been under scrutiny for a long while before its official nationwide prohibition.

In 1990, under the Delaney Clause, the FDA banned the additive in cosmetics and topical drugs after research found it to be carcinogenic — having the potential to cause cancer — in high doses for rats in lab tests. However, because it didn’t have the same results in humans, these studies did not raise additional concerns. 

And although there is still no confirmation that it may cause cancer in people, the Federal Food, Drug, and Cosmetic Act (FD&C Act) states that the FDA can no longer authorize it “if it has been found to induce cancer in humans or animals.” 

Additionally, Lurie says there are a “variety of technical reasons” that make it difficult to ever be certain whether substances such as food additives cause cancer in humans.

Which states banned the substance prior to the nationwide law?

According to CSPI, California initially outlawed the use of red dye No. 3 in their foods in 2023. Ten other states, including South Dakota, Washington, Illinois, and Missouri, additionally introduced the legislation in recent years in order to restrict its use.

Some companies have now started turning to red dye No. 40, which is considered a healthier option, as it hasn’t been directly associated with cancer in animals.

But California has banned red dye No. 40 from any foods or beverages sold in public schools beginning in September, following concerns of behavioral and attention difficulties among children, as reported by CNN. 

One study also found a possible risk of accelerated immune-system tumor growth in mice. 

How does this shift the FDA?

Now that this ban is in place, the “food landscape” of the U.S. is slightly closer to that of the European Union, which had prohibited the dye back in 1994, with the exception of a few maraschino cherry products. 

“There is not a rational reason within FDA’s mission that they did not ban red dye #3 from food in the 1990s,” said Dr. Jennifer Pomeranz, an associate professor of public health policy and management at New York University’s School of Global Public Health.

She added that it is still unclear as to why the agency takes “so long to ban ingredients with known health harms.”

But Mande claims this is due to the priorities of many businesses being misplaced. 

“This is because food companies have lost sight of their primary mission, providing food we will thrive on, and focusing entirely on their profits instead,” he said. 

“Unfortunately, the U.S. government doesn’t fund the research needed to determine the exact health risks posed by Red Dye #3. Industry works with Congress to block funding for the needed research.”
