I mean, their 70% cocoa clocks in at 134% the mentiomed safe limit while the 80% cocoa from mast is at 14% (both reportedly for 1 oz of chocolate) according to the previously linked data. If the main determinant was the amount of cocoa, than I would have expected 80% to be higher.

Of course a company could be lying about the cocoa %, or using some type of filler, etc. But it seems plausible that there might be other causes. For example, perhaps some cocoa plantation locations have more lead in their soil, etc.

Tony’s did actually respond to CR, claiming these are not food safety standards. They did not appear to mention why their chocolate had any different levels of lead than other companies, just that leaf is absorbed from the soil.
