Hershey's sued after study found lead and other heavy metals in its dark chocolate

Hershey's misled buyers of its dark chocolate by not disclosing the products contain lead and another potentially harmful chemical, according to a lawsuit filed against the candy maker. 

Nassau County, New York, resident Christopher Lazazzaro said he would not have bought dark chocolate products sold by Hershey had it revealed the bars contains lead and cadmium, according to the suit filed Wednesday in federal court in Central Islip, New York.

Lazazzaro relied on the company's presentation of its candy bars as containing only dark chocolate ingredients and as safe for consumption, according to the legal filing. Instead, he purchased and paid more than he would have had he known "the truth about the products," the suit states.
