The Food and Drug Administration is considering a ban on food dye, Red No. 3. The agency has been reviewing a 

the colorant since 2022. The petroleum-based dye has been used for more than 50 years in thousands of products including candy, snack foods, and soda. An FDA spokesperson tells NPR a decision could come "soon."

Questions about the dye's potential health effects go back decades. The FDA 

banned the use of the Red No. 3 in cosmetics

 and medicated ointments and lotions back in 1990. Research showed the dye could cause cancer in animals in high doses. But the agency concluded it was safe in the amounts used in food.

evaluated the safety of Red No. 3 "multiple times"

 since its original approval for use in food in 1969.

But the concern about use of the dye in food has grown. Last year, the state of 

to ban Red No. 3 — the law is slated to take effect in 2027. Lawmakers in ten other states have introduced legislation to ban Red No. 3 in foods, according to the 

Center for Science in The Public Interest.

State actions like these put pressure on the FDA to make a decision on this issue. "Over the past few years, there have been an increasing number of state bills to ban certain additives and set limits for certain contaminants," a spokesperson for the FDA told NPR via email. "However, a strong national food safety system is not built state by state."

As NPR reported last year, California's Environmental Protection Agency 

 research on synthetic dyes, and found evidence that when consumed in food they can negatively affect children's behavior. Out of about 25 studies, more than half pointed to an association with behavior.

"I think the evidence is compelling from those human studies that children's consumption of synthetic food dyes can contribute to increases in symptoms like inattention, hyperactivity in some children," Mark Miller, a scientist with California's EPA's Office of Environmental Health Hazard Assessment told NPR in 2023.

The FDA has said it will continue to examine the effects of color additives on children's behavior.

"The totality of scientific evidence shows that most children have no adverse effects when consuming foods containing color additives, but some evidence suggests that certain children may be sensitive to them," wrote the authors of an FDA consumer update titled "

But the Center for Science in the Public Interest, which brought the Red No. 3 petition

says there's no reason to add synthetic dyes to food.

"Red 3, like every food dye, only serves as a marketing tool for the food industry," says 

 principal scientist for food additives and supplements at CSPI. "It's just there to make food look visually appealing so that consumers want to spend their money on it." 

He points out that Red No. 3 is banned or severely restricted in 

 since 2008, including a group of red, blue, yellow and green dyes and a rarely used orange hue.

Red No. 3 has been singled out for a ban due to the evidence on cancer in animals. "It's very low-hanging fruit that the FDA really should have picked decades ago," Galligan 

Earlier this year, California Gov. Gavin Newsom signed a second 

The National Confectioners Association pointed NPR to the industry's latest statement on food additives. It says the industry is committed to food safety, and that its products are made "

The food industry has shown that it can pivot to alternatives. For instance, when Kraft foods decided to take synthetic food dyes out of its mac and cheese products, it

 with colors from spices such as paprika and turmeric.
