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.
There's more lead allowed in a liter of drinking water in the US than a serving of any of the chocolates being reported, as far as I can find. (15 micrograms per liter.) Provided nobody's eating a few dozen bars of chocolate in a single sitting I can't imagine accumulating enough to cause acute harm from the chocolate alone. Chasing down Hershey, Nestle et al to hold them accountable is great, but in terms of toxic metals we'd have more success and greater impact lighting up the news about water supplies.
Just mildly frustrated that I continue to see talk about chocolate while drinking water is a necessity and consumed in greater amounts daily but rarely gets reported outside of extreme cases like Flint.
