There has been research showing the presence of lead (Pb) and cadmium (Cd) in chocolate since 2001, although no evidence of harm from its consumption has been reported. For example, As You Sow, a consumer health protection organization, recently performed laboratory testing to measure levels of Pb and Cd on 50 different chocolate products available at retailers across California. The organization reported that 35 of the 50 chocolate products contained measurable levels of Pb and/or Cd. However, one should note that the presence of these metals in a food product alone is not sufficient to evaluate potential risks to consumers. The scientists at Cardno-ChemRisk presented work entitled “An exposure and health risk assessment of lead (Pb) in chocolate” at the annual Society of Toxicology meeting in New Orleans last week. To assess whether the ingestion of Pb-containing chocolate could pose a health risk to adults and children, our scientists used the EPA’s Adult Lead Methodology (ALM) and Integrated Exposure Uptake Biokinetic (IEUBK) models to predict the blood Pb levels (BLLs) of adults and children (aged 1-7) ingesting various amount of chocolate on a daily basis for 1 year. The results of this analysis demonstrated that in all cases, background Pb exposure was the primary contributor to estimated BLLs in children and adults, and Pb exposure from chocolate did not significantly increase estimated BLLs. Our findings indicate that simply reporting the Pb content of a chocolate product is not sufficient to evaluate health risk; the health risks of Pb in chocolate should be evaluated in the context of estimated background exposures using predictive blood Pb models. The SOT abstract of “An exposure and health risk assessment of lead (Pb) in chocolate” can be found here, along with the other abstracts that our staff presented.
