You've probably seen the viral TikToks or the frantic Facebook posts. Someone standing in a grocery aisle, holding a bag of neon-red chips, claiming that "this stuff is illegal in Europe!" It makes for a great headline. It's also, honestly, mostly a misunderstanding of how international law works.
The truth about where Red 40 is banned is a lot more "it’s complicated" than "it’s illegal."
If you live in the United States, you’re used to seeing Red 40 (or Allura Red AC) in everything from strawberry frosting to pickles and even some brands of smoked salmon. But if you hop on a plane to London or Paris, those same products look... different. They’re duller. Earthier.
Why? Because while Red 40 isn't technically "banned" in the way a narcotic is, most of the world has made it so annoying to use that companies just gave up on it.

The European "Soft Ban" and Why It Matters
Let’s get the big one out of the way. People often say the European Union (EU) banned Red 40. That is technically false.
The European Food Safety Authority (EFSA) actually lists Allura Red (E129) as an approved additive. However, back in 2010, the EU threw a massive wrench into the food industry’s gears. Following the "Southampton Study"—a famous piece of research by the University of Southampton—regulators decided that certain dyes might be linked to hyperactivity in children.
Instead of an outright ban, they passed a law. Any food containing Red 40 (and five other dyes) must carry a warning label that says: "May have an adverse effect on activity and attention in children."
Basically, it’s the "cigarette warning" of the snack world.
Imagine you’re a marketing executive for a major candy brand. Do you want your bright red gummy bears to have a label that suggests they might make kids hyperactive? Of course not. It’s a sales killer. So, most European manufacturers didn't wait for a ban. They voluntarily swapped Red 40 for natural alternatives like beetroot juice, paprika extract, or elderberry.
Where is Red 40 Banned or Heavily Restricted Right Now?
While the EU uses warning labels, other places have been more aggressive. If you are looking for a specific list of where Red 40 is banned or basically non-existent, here is the current 2026 landscape:
- Switzerland: Switzerland is famously strict. They have effectively banned the use of Red 40 in most food products because they lean heavily on the "precautionary principle." If there's a doubt about safety, it stays out.
- The United Kingdom: Much like the EU, the UK requires the "warning of doom" on packaging. This has led to a functional ban where you will rarely find it in mainstream supermarkets.
- Norway and Sweden: These countries actually had outright bans on many azo dyes (the chemical family Red 40 belongs to) for decades. When they joined the European Economic Area, they had to align with EU rules, but their domestic food culture remains extremely hostile to synthetic dyes.
- California (The 2024-2027 Shift): This is the biggest news for Americans. In late 2024, California passed the California School Food Safety Act. Starting in late 2027, Red 40 will be officially banned from all food served in California public schools.
It’s not just California, either. In early 2026, states like New York, Illinois, and Pennsylvania are currently debating similar bills. We are watching a "state-by-state" ban happen in real-time.
The Great Divide: FDA vs. The World
Why is the US FDA so chill about something that Europe treats like a hazard?
The FDA’s stance is basically: "Show us the bodies." They require "convincing evidence" of harm before they pull an additive. Their current position is that Red 40 is safe when consumed within the Acceptable Daily Intake (ADI) of 7 mg per kg of body weight.
But here is the catch. Most of the original safety studies were done decades ago. Critics, like the Center for Science in the Public Interest (CSPI), argue that these studies didn't look closely enough at neurobehavioral issues or how dyes affect the gut microbiome.

"Honestly, it's a difference in philosophy," says Dr. Mark Corkins, chair of the American Academy of Pediatrics Committee on Nutrition. The US assumes a chemical is "innocent until proven guilty." Europe assumes it's "guilty until proven innocent."
Is it Actually "Petroleum" in Your Food?
One of the grossest-sounding facts about Red 40 is that it’s "made from petroleum."
Yes, that’s technically true. It is a synthetic chemical derived from crude oil. If that sounds like something you shouldn't be eating, you’re not alone. However, the food science community is quick to point out that the final product is a highly purified chemical that bears no resemblance to the gasoline in your car.
But the "yuck factor" is a huge driver of the bans we're seeing. Parents in 2026 are increasingly opting for "clean labels." They want to see "Beet Juice" instead of "FD&C Red No. 40."
The Ticking Clock: What Happens Next?
The food industry is already reading the writing on the wall.
Even without a federal ban from the FDA, major companies are jumping ship. In April 2025, the FDA announced it would begin a formal review to phase out several synthetic dyes by the end of 2026 due to mounting pressure from state legislatures.
Brands like Mars and Kellogg’s have already started reformulating. If you’ve noticed your favorite cereal looks a little "greyer" or "more purple" lately, that’s why. They are switching to fruit-based pigments to avoid the looming bans and the public relations nightmare.

If you're worried about Red 40, you don't have to wait for the government to act. You've got the power of the ingredient label.
- Look for the Numbers: In the US, look for "Red 40." In Europe or on imported goods, look for "E129."
- Check the "Healthy" Stuff: You’d be surprised. Red 40 hides in flavored yogurts, "fruit" snacks, and even some brands of pickles and salad dressings.
- Choose "No Artificial Colors": Many brands now explicitly state they use natural sources. Look for "colored with fruit and vegetable juice."
- Watch the "Red 3" Ban: Don't confuse Red 40 with Red 3. Red 3 (Erythrosin) actually is being banned federally in the US for food use because of links to thyroid cancer. If a company is still using Red 3 in 2026, they are likely on their last batch of inventory before it becomes illegal.
The world of food additives is changing fast. While Red 40 isn't globally "illegal" yet, the "warning label" culture of Europe has effectively pushed it out of most of the developed world. With California leading the charge in the US, it’s only a matter of time before that bright, artificial glow disappears from American shelves too.
Your Next Step: Grab three items from your pantry right now—specifically a snack, a condiment, and a cereal. Flip them over and check for "Red 40" or "Allura Red." If you find it, try searching for a "dye-free" version of that same product online; you'll likely find that the brand already makes a cleaner version for the European market.
