The lack of controls is really worrying. Sure, there is not supposed to be mercury in corn syrup. But how do we know it's getting in because of that processing step, rather than because of contaminated soil or water? That would cause a different problem, with low levels of mercury distributed across many kinds of food. People avoid tuna, not because it contains "detectable mercury," but because it contains substantially more mercury than other kinds of food. There should not be mercury in anything we eat. But we can't make sensible choices without knowing the relative risks of a serving of tuna, a bottle of soda, or a salad that was not organically grown.
