I think the GMO labeling problem is related, but separate. To date, no one has ever proven that GMO foods are somehow unsafe, much like the flap over rBST in milk, for which products proclaiming they are rBST free have in small print that no difference between rBST cow milk and non-rBST cow milk has ever been demonstrated. With both GMO and rBST, there's possibly a food quality issue, but not a food safety issue. Proposition 65, however, actually claims that there's a safety issue. And, to be sure, the chemicals on the list are indeed legitimately unsafe; it's just that the context and the probable dosage or actual level of exposure in many cases makes them largely irrelevant.
