Debunking the "Skittles Ban" Myth
The story of the "Skittles ban" is a prime example of how misinformation can spread rapidly, driven by viral headlines that twist legislative details. While it's true that California has passed a landmark food safety law, Assembly Bill 418 (AB 418), it does not actually ban Skittles. The confusion stems from an earlier version of the bill that included a fifth ingredient, titanium dioxide—a whitening agent used in Skittles—which was ultimately removed from the final legislation. This article will clarify what California's new law does ban, the health concerns behind it, and why Skittles were never truly at risk.
The Real Story: What California's AB 418 Actually Bans
Signed into law by Governor Gavin Newsom in October 2023, the California Food Safety Act prohibits the manufacture, sale, or distribution of four specific food additives. These are chemicals that are already banned in Europe and have been linked to potential health issues in animal studies. The law is set to go into effect on January 1, 2027, giving manufacturers time to reformulate their products.
The four banned additives are:
- Red Dye 3 (Erythrosine): A synthetic dye linked to thyroid cancer in lab rats. It is used in many candies, cookies, and other processed foods. Separately, the FDA also banned Red Dye 3 from food in January 2025.
- Brominated Vegetable Oil (BVO): An emulsifier used to keep citrus flavors from separating in some soft drinks. Concerns about potential nervous system damage arose from animal studies.
- Potassium Bromate: An additive used to strengthen dough for baked goods. It is classified as a possible human carcinogen by the International Agency for Research on Cancer.
- Propylparaben: A preservative used in some pastries and trail mixes. Studies have suggested it can disrupt hormone function.
The Titanium Dioxide Misunderstanding
The reason Skittles became the poster child for the ban is because the initial draft of AB 418 included titanium dioxide. This chemical is used to create a smooth, vibrant, and uniform color coating on candies like Skittles and M&M's. In 2022, the European Union banned titanium dioxide as a food additive over concerns about its potential genotoxicity, or ability to damage DNA. A class-action lawsuit filed against Mars Inc. in 2022 further fueled the narrative. However, significant lobbying efforts led to titanium dioxide being dropped from the final California bill.
Mars Wrigley's Proactive Reformulation
In a related but separate move, Mars Wrigley, the maker of Skittles, announced in May 2025 that it had quietly removed titanium dioxide from its U.S. product line by the end of 2024. This decision was in response to ongoing consumer pressure and shifts in the food industry toward cleaner ingredients, not a direct mandate from the California law. This reformulation means that the Skittles sold in the U.S. now align with the titanium dioxide-free versions already sold in the European Union. The candy's recipe was changed preemptively, well before California's AB 418 even went into effect.
Affected vs. Unaffected Products
To understand the actual impact of AB 418, it's helpful to see which products are truly affected versus those that were mistakenly associated with the bill.
| Product | Status Under California's AB 418 | Primary Additive of Concern |
|---|---|---|
| Skittles | Not Banned (Exempted from final bill) | Titanium Dioxide (Removed by manufacturer) |
| Pez (certain flavors) | Banned (if not reformulated) | Red Dye 3 |
| Peeps (certain colors) | Banned (if not reformulated) | Red Dye 3 |
| Cookies, Icings | Banned (if not reformulated) | Red Dye 3, Propylparaben |
| Some Sodas | Banned (if not reformulated) | Brominated Vegetable Oil (BVO) |
| Some Baked Goods | Banned (if not reformulated) | Potassium Bromate, Propylparaben |
The Broader Impact and Future of Food Regulation
The California Food Safety Act is significant because of the state's massive economic influence. As a huge market, California often drives national and even international changes in product manufacturing. Rather than producing different versions of the same product for different states, many companies find it more efficient to reformulate their products nationwide. This means that the impact of AB 418 will likely be felt far beyond California's borders, leading to the gradual phase-out of these four chemicals from the U.S. food supply.
The law also serves as a strong signal to the FDA that stricter oversight of food additives is needed. The federal agency's reviews of many food chemicals occurred decades ago, and consumer advocates argue that new scientific findings warrant re-evaluation. California's action puts pressure on the FDA to update its regulations and aligns the U.S. more closely with the food safety standards of the European Union.
Conclusion
So, why are Skittles banned in California? The short answer is they aren't, and never were. The viral rumors conflated the brand's association with titanium dioxide and California's broader food safety legislation. The real story is about California taking a proactive stance on food regulation by banning four specific additives that most manufacturers had already eliminated from their European-marketed products. The unintended consequence of the misleading headlines is that it brought much-needed public attention to the ingredients lurking in many processed foods, even if Skittles was ultimately the wrong target.
