Heavy Metal Findings in Tony's Chocolonely
In December 2022, the consumer organization Consumer Reports released a study detailing the presence of lead and cadmium in 28 dark chocolate bars from various brands. The findings revealed that Tony's Chocolonely's 70% dark chocolate contained heavy metal levels that exceeded the maximum allowable dose levels (MADLs) set by California's Proposition 65 for lead. Specifically, the Tony's Chocolonely 70% bar showed a lead level of 134% of the MADL.
The Source of Heavy Metals
The presence of heavy metals like lead and cadmium in dark chocolate is not unique to Tony's Chocolonely and is an industry-wide issue rooted in how cacao beans are grown and processed.
- Cadmium: This heavy metal is absorbed from the soil by the cacao plant as it grows, ending up in the beans. The level of cadmium is often related to the specific growing region and the age of the tree.
- Lead: Lead contamination typically occurs after harvesting. As cacao beans are left to dry in the open air, lead-containing dust and soil can settle on the beans. Improvements in harvesting and cleaning practices can help mitigate lead contamination.
Comparing Regulatory Standards
The public concern about these heavy metal levels largely stems from how different safety standards are interpreted. Tony's Chocolonely, a European company, follows European Food Safety Authority (EFSA) standards, which differ from California's Proposition 65 guidelines used in the Consumer Reports study.
- California's Proposition 65 (Prop 65): This regulation sets a maximum allowable dose level (MADL) that is much lower and is not an FDA-enforced food safety standard. It is more of a warning threshold.
- European Food Safety Authority (EFSA) / U.S. Food and Drug Administration (FDA): These agencies have established safety standards for food products that are met by Tony's Chocolonely.
For most consumers, moderate chocolate consumption does not pose a significant health risk, but vulnerable populations like children and pregnant individuals should be more mindful of their intake.
Manufacturer Response and Other Test Results
Following the Consumer Reports study, Tony's Chocolonely addressed the findings directly. The company stated that it takes health and safety seriously and regularly tests its ingredients to ensure they are well within the range deemed safe by the EFSA and FDA. Tony's Chocolonely pointed out that the Consumer Reports study relied on Prop 65 guidelines, which are not food safety standards.
Furthermore, an independent 2024 study by ÖkoTest, a German consumer research organization with stringent testing standards, rated Tony's Chocolonely dark chocolate as 'Good,' confirming its safety within established food and safety requirements.
Comparison of Testing Standards and Results
| Aspect | Consumer Reports (2022) | ÖkoTest (2024) | Tony's Chocolonely (Internal Testing) |
|---|---|---|---|
| Standards Used | California's Proposition 65 MADLs | Stringent EU food and safety standards | EFSA and FDA food safety standards |
| Primary Concern | High lead and cadmium levels based on Prop 65 thresholds | Overall quality, environmental, and safety compliance | Adherence to legal and internal safety requirements |
| Tony's 70% Dark Chocolate Result | High in lead (134% of Prop 65 MADL) | Rated 'Good,' confirms low heavy metal levels | Passes all internal checks based on EFSA/FDA |
| Interpretation | Potentially concerning levels for daily consumers | Safe for consumption under regulatory standards | Safe and compliant for consumers |
How to Minimize Heavy Metal Exposure from Chocolate
For consumers concerned about heavy metal intake, a balanced approach to chocolate consumption is recommended. Since chocolate is just one of many sources of environmental heavy metals, overall dietary awareness is key.
- Enjoy in moderation: Dark chocolate is a treat, not a primary food source. Limiting consumption, especially for high-cacao products, can reduce overall heavy metal intake.
- Vary your chocolate brands: Mixing up brands and products can prevent overconsumption of a specific brand that might have higher levels of a certain heavy metal.
- Choose lower cacao percentages: Some studies suggest that cadmium levels, in particular, may increase with higher cacao percentages. Opting for a 70% bar over an 85% one, for example, could slightly reduce intake.
- Consider milk chocolate: Milk chocolate contains lower levels of cocoa solids and generally has lower heavy metal concentrations. However, it does contain more sugar and should also be consumed in moderation.

Conclusion
The presence of lead in Tony's Chocolonely dark chocolate, as reported by Consumer Reports in 2022, is a fact, but it requires careful interpretation. While the levels exceeded California's strict warning thresholds, Tony's Chocolonely and other food safety authorities maintain that their products are safe for consumption under federal and European standards. The heavy metals are environmental contaminants found across the industry, and their risk is most significant with frequent, high-volume consumption. By enjoying dark chocolate in moderation and being mindful of overall dietary intake, consumers can manage any potential concerns related to heavy metal exposure. It is important to consider the various standards and context behind testing results when evaluating the safety of any food product.
