Europe Banned It in 2022. Skittles Dropped It. Your School's White Icing Might Still Have It.

Here is a strange fact about the white on your food. The same mineral pigment that makes house paint bright and sunscreen opaque has also been used to make candy shells, icing, and creamers look whiter. It is called titanium dioxide, and since 2022 it has been illegal in food across the entire European Union.

In the United States, it is still allowed. This post covers why Europe pulled it, why the FDA has not, which states are now going after it in school food, and how you can spot it on a label before it ends up on a cafeteria tray.

What it actually does in food

Titanium dioxide, sometimes written TiO2, does one job: it makes things look brighter and more opaque. It does not add flavor, protect against spoilage, or improve nutrition. It is purely cosmetic.

That is the part worth sitting with. A food can be perfectly safe to eat without being perfectly white. When a pigment has no function except appearance, the bar for proving it is safe for kids should be high.

Why Europe said no

The EU banned titanium dioxide as a food additive in 2022. The concern is genotoxicity, which means the possibility that tiny particles of the pigment can damage DNA. European regulators could not rule that out, and without a safe level they decided the additive had to go.

To be fair, the science is still debated. An EU court later annulled a separate 2019 decision that classified the chemical as a possible carcinogen, and some reviews found limited evidence of harm from food uses. But the food rule did not change. Europe chose caution, and that is a very different default than the one we use here.

Why the FDA has not followed

The FDA maintains that titanium dioxide is safe in food within its limits, which cap it at 1 percent of a food's weight. Industry groups agree. The Center for Science in the Public Interest and other advocacy groups have pushed the agency to ban it, but so far the rule has not moved.

The May 2025 MAHA Report listed titanium dioxide among the additives of concern, which kept the issue in the spotlight. Companies noticed. Mars quietly removed it from Skittles in the U.S. by the end of 2024, without making a public announcement. If a candy maker can reformulate a product that bright, a school cafeteria can reformulate a snack.

The states are moving school by school

California's original Food Safety Act, AB 418, had titanium dioxide on its list. It was cut before the bill passed, so the final law covers red dye 3, propylparaben, brominated vegetable oil, and potassium bromate instead. Early drafts of the school dye bill, AB 2316, also named it.

Utah is taking the next swing. Its 2026 bill, HB 350, adds titanium dioxide to the state's school food list, alongside potassium bromate, propylparaben, and the seven synthetic dyes already covered. As introduced, it would also remove the exception for small districts and charter schools. Check the Utah legislature's site for the bill's final status, because the pattern is what matters: when one state moves, others copy the list.

How to spot it on a label

Look for "titanium dioxide" or "TiO2" in the ingredients. It tends to show up in white icing, powdered coatings, candy shells, some dressings, gum, and creamers. The tricky part is that colors exempt from certification can legally appear as just "color added" or "artificial color," so the plain words on the label do not always tell you everything.

Here is a simple move. Take a photo of the ingredient list on any packaged item your cafeteria serves, then ask your nutrition director for the product specification sheet. That document lists exactly what is in the item, and districts are usually able to share it.

What students can do this month

Pick five packaged items from your cafeteria and check them. Write down what you find. Then bring that short list to your school nutrition director or a board meeting. One page of real ingredients from your own district is harder to wave away than any national statistic.

Food that looks bright white was never a health goal. If a pigment can leave Europe's food supply and disappear from a candy aisle, it can leave your cafeteria too. Join the CleanEats Coalition and help us make it happen at cleanlunchcoalition.org/join-us.
