Check out this article. When I first was told that HFCS had mercury, I was skeptical. I've done some research, and now know this is true. Admittedly, US producers of HFCS state they no longer use mercury in the production of HFCS. However, large companies of refined food in this country get HFCS from foreign sources (namely China). I'm SURE these foreign governments have American's safety in mind when they produce products for export (nudge, nudge, wink, wink).
