The National Confectioners Association (NCA) has defended dark chocolate confectionery brands such as Hershey, Trader Joe’s, and Lindt, against claims by Consumer Reports that they contain high levels of cadmium and lead. The consumer advocacy group's testing found that 23 of 28 bars exceeded California's prop 65 limits for these metals. However, the NCA maintains that these levels are within compliance and that the products are safe to consume. The NCA is also working with As You Sow to reduce cadmium in chocolate through means like bean cleaning and potential changes in farming practices.
