"The dye, linked in studies to hyperactivity in children and the potential to cause cancer, has already been banned in cosmetics but remains legal in food products." https://www.post-gazette.com/news/health/2025/01/05/red-dye-3-fda-food-coloring/stories/202412260101
An article in Food Safety magazine (LINK) provided this:
"FDA made its decision in response to a 2022 color additive petition filed by the Center for Science in the Public Interest, Consumer Reports, and 22 others, which cited, among other data and information, two studies that showed cancer in laboratory male rats exposed to high levels of red dye 3 due to a rat-specific hormonal mechanism. Although FDA granted this petition, in its decision, FDA asserted that these studies are not necessarily relevant to human health; according to the agency, harmful exposure levels for male rats are much lower than for humans, and studies in humans and in other animals did not show carcinogenic effects. In a December 2024 Senate hearing, when asked why the agency still allows potentially harmful red dye 3 in food but not cosmetics, FDA Deputy Commissioner for Human Foods Jim Jones reiterated this position, explaining that the current scientific consensus is that the additive’s mode of carcinogenicity in animals is not applicable to humans.""Regardless, beliefs that red dye 3 and other artificial food colorants are harmful to human health are widely held. In October 2024, Consumer Reports delivered another petition—with 80,000 signatures—urging the agency to ban red dye 3 in foods, citing, in addition to its potential carcinogenicity, that the dye is associated with hyperactivity and other neurobehavioral effects in children. A November letter from 23 Congress members also urging FDA to ban red dye 3 echoed the same concerns, and noted that the colorant is not allowed for food use by the EU, Australia, or New Zealand."
