Between 2014 and 2017, As You Sow (AYS), a non-profit corporation in California, tested various chocolate products for the presence of cadmium (Cd) and lead (Pb). This testing revealed that numerous chocolate products had elevated Cd or Pb concentrations that, combined with typical serving sizes, indicated the potential for Cd and Pb exposures greater than the Proposition 65 Maximum Allowable Dose Levels (MADLs). Since March 2018, a committee of four experts (the Expert Committee) has been investigating and reporting on the predominant sources of cadmium (Cd) and lead (Pb) in chocolate products and recommending feasible measures that may be taken to meaningfully reduce Cd and Pb levels in these products. The Expert Committee was charged with preparing this report.
