Is There Lead and Cadmium in Hot Chocolate and Brownie Mix?


There may be potentially harmful amounts of heavy metals in a wide range of chocolate products; not only in dark chocolate, but also in milk chocolate cocoa powders, brownie mixes, and chocolate chips, according to new research from Consumer Reports.

Researchers at the organization measured levels of lead and cadmium in 48 products, including:

  • Cocoa powder
  • Chocolate chips
  • Milk chocolate bars
  • Brownie and cake mixes
  • Hot chocolate

These products came from some larger brands, like Hershey’s, Nestlé, and Ghirardelli; smaller brands like Droste and Navitas; and were sold at national retailers such as Costco, Trader Joe’s, Target, Walmart, and Whole Foods.

As expected based on earlier testing, dark chocolate products tended to have higher levels of heavy metals than milk chocolate, the new research found.
