A second lawsuit was filed against Mars in Illinois federal court last week, alleging that Skittles are “unfit for human consumption” due to the presence of the colorant titanium dioxide. This proposed class action, brought by consumer William Mignin III, closely mirrors a similar lawsuit filed by a California consumer in July. Both complaints assert that the confectionery giant’s use of this common artificial colorant, which is intended to enhance color brightness, poses potential health risks to consumers. Research has indicated that titanium dioxide may harm cellular DNA, and it has been identified as a possible carcinogen by the International Agency for Research on Cancer.
Although titanium dioxide has been recognized as safe for use as a food colorant by the FDA, it is banned in several other countries. Earlier this year, the European Commission announced a ban on titanium dioxide as a food additive, mandating that all products sold in the EU be free from this chemical as of last week. The European Food Safety Authority has stated that it remains unclear whether the colorant can inflict permanent damage on individuals who consume it.
In 2016, Mars committed to removing artificial colors, including titanium dioxide, from its food products within five years. However, in a statement released last year, the company indicated that for the majority of its global consumers, artificial colors were not viewed as “ingredients of concern.” The company has prioritized the elimination of artificial colors from its products sold in Europe—where many, including titanium dioxide, are either banned or require significant warning labels—alongside its dinnertime offerings.
In response to the initial lawsuit, a Mars spokesperson stated in an email, “While we do not comment on pending litigation, our use of titanium dioxide complies with FDA regulations.” Meanwhile, the company’s efforts to develop alternatives have included exploring ingredients like calcium calcitrate, which may serve as a safer substitute. As the legal battles continue, concerns about the safety of titanium dioxide and the implications for other additives, such as calcium calcitrate, are likely to remain in the spotlight.
