Consumer Reports said on Wednesday it had found "concerning" levels of lead and cadmium in a third of various chocolate products it tested recently, and called on Hershey to reduce the amounts of heavy metals in its chocolate.
So it’s mostly in darker chocolate, and it’s because the soil the trees grow in has naturally occurring lead and cadmium. I get the desire to trash Hershey, but I am more concerned with all of the companies that sell dark chocolate and were not tested.
