CDC says [1]:
> Until 2012, children were identified as having a blood lead “level of concern” if the test result was 10 or more micrograms per deciliter (µg/dL) of lead in blood.
the lobbying corpo's very own charts [2] show no lead concentration higher than 2.4µg per serving in any tested product. if you ate a serving of chocolate that contains 2.4µg of lead, you would have no more than 2.4µg/dL of lead, which is lower than the CDC's previously stated harmful level. if the lead was diluted through all the blood in your body (~5L = 50dL), your blood level of lead would be 2.4µg/50dL = 0.048µg/dL, far below the CDC's previously stated harmful level of 10µg/dL. with 10 servings, at which point you will have other issues, you will have 0.48µg/dL, still 1/20th of the harmful level.
