To determine the risk posed by the chocolates in CR’s test, we used California’s maximum allowable dose level (MADL) for lead (0.5 micrograms) and cadmium (4.1mcg).
CR’s scientists measured heavy metal content against California’s standard levels because there are no federal limits for the amount of lead and cadmium most foods can contain, and they believe that California’s standard levels are the most protective available.
