CR tested a mix of brands, including smaller ones, such as Alter Eco and Mast, and more familiar ones, like Dove and Ghirardelli. 

For 23 of the bars, eating just an ounce a day would put an adult over a level that public health authorities and CR’s experts say may be harmful for at least one of those heavy metals. Five of the bars were above those levels for both cadmium and lead.

Apparently you can still indulge once in a while, but don't make it a daily thing! I'm definitely not introducing chocolate to my kids anytime soon.
