Admitting that the article is a "What should I do?" personal health advice column - it still struck me that the contamination has been well-known for decades, yet there is no hint at either the chocolate companies or regulators caring enough to even consider doing anything. (I don't count empty-platitude press releases from the former as "doing anything".)

Idea: The FDA equips a few inspectors with good XRF (XRay Fluorescence) testers, and plays a "let's drive the most-contaminated ~3% of the products out of the U.S. market" game.
