Lindt Chocolate Lawsuit: Lead & Cadmium in Dark Chocolate Claims

The Testing That Triggered the Litigation

In December 2022, Consumer Reports published an investigation testing 28 dark chocolate products for heavy metals. The results found that nearly all tested products contained measurable amounts of lead and cadmium, but several brands -- including Lindt's Excellence 70% Cacao and 85% Cacao bars -- showed particularly elevated levels that Consumer Reports characterized as a concern for regular adult consumers and a potential danger to children who consume any amount.

Lead has no established safe level of consumption according to the FDA, and cadmium is a known human carcinogen linked to kidney damage and increased cancer risk with cumulative exposure. The Consumer Reports testing applied California's Proposition 65 standards -- among the strictest in the US -- as a reference point and found several Lindt products exceeded the daily exposure levels that would require a Prop 65 warning if the products were sold in California.

The Legal Claims Against Lindt

Class action lawsuits were filed against Lindt in federal courts in multiple states following the Consumer Reports publication. The lawsuits advance consumer protection and fraud theories: Lindt markets its dark chocolate as a premium, high-quality product and charges premium prices accordingly. Plaintiffs allege that reasonable consumers who paid these premium prices did not know they were purchasing products containing potentially harmful levels of heavy metals, and that Lindt's marketing failed to disclose material information about the products' heavy metal content.

California plaintiffs have additional claims under Proposition 65, which requires businesses to provide clear warnings before knowingly exposing any individual to a chemical known to the state to cause cancer or reproductive harm. Lead and cadmium are both on the Prop 65 list. Plaintiffs allege Lindt sold products in California without required Prop 65 warnings despite being aware of the heavy metal content through its own quality testing.

Where Heavy Metals Come From in Chocolate

Heavy metals in chocolate originate primarily from the cacao plant itself, which absorbs metals from soil. Cacao grown in certain regions -- particularly Latin America and West Africa -- is cultivated in soils that naturally contain higher concentrations of cadmium, partly due to historical volcanic activity and geological composition. Lead contamination occurs during the drying and fermentation process, when cacao beans come into contact with contaminated soil or dust.

This is not a manufacturing defect in the traditional sense -- the metals are present in the raw agricultural commodity. However, chocolate manufacturers have significant choices about which cacao sources to use, how to blend beans from different origins, and what testing and remediation measures to apply. Plaintiffs argue that premium chocolate companies like Lindt have the knowledge and resources to source lower-contamination cacao and that failure to do so -- while marketing products as premium quality -- constitutes actionable misrepresentation.

Who Qualifies for the Lindt Lawsuit

The proposed class includes US consumers who purchased Lindt dark chocolate products within the applicable statute of limitations period, generally four years in California and varying in other states. The strongest claims belong to regular dark chocolate consumers in California who purchased products that would have required Prop 65 warnings, and to consumers who allege they paid premium prices relying on Lindt's quality marketing.

Parents who purchased Lindt dark chocolate for regular consumption by children may have additional claims given that children face disproportionately higher health risks from the same level of heavy metal exposure as adults, due to their smaller body weight and developing organ systems.

Case Status 2026

The Lindt heavy metals litigation is in active proceedings in federal courts. Lindt has contested the legal theories and the methodology used in consumer testing, arguing that the levels found are within naturally occurring ranges and that its products comply with all applicable food safety regulations. Class certification is pending.

The case is one of several similar heavy metals lawsuits filed against chocolate manufacturers following the Consumer Reports investigation. Other defendants include Hershey, Trader Joe's, and Theo Chocolate. Collective litigation pressure has prompted industry discussions about sourcing and testing standards.
