The issue isn't that it's a health risk directly, it's just the result of some very reasonable principals. The "Delaney Clause" in the Food Additives Amendment of 1958 of the Federal Food, Drug, and Cosmetic Act is why it's getting banned. If something is known to cause cancer in animals, and it isn't necessary for the production of the food, then it shouldn't be included.
This is simply an application of the Precautionary Principle to things already associated with harm. Since we can't know all the goods or harms that can come from a substance, if something is known to cause potential harm and it's unnecessary, then we shouldn't consume it. The human body is an absurdly complex multi-variate system, and throwing a bunch of unnecessary random shit at it not a great idea in general, but is generally reasonable when we don't know whether it's producing harms or benefits or neither. However, when we know these additives can produce harms, and it is wildly impractical to do repeated, controlled longitudinal studies with large sample sizes on humans, all at various levels of exposure. So, since the substances are entirely unnecessary we might as well just avoid them unless they are essential to creating products.
