There is a lot of testing available, that would be very good to have the results for, especially in our food. Heavy metals are easy. A little more expensive are the organic compounds: think herbicides, fungicides, insecticides. There is no agency that monitors those ingredients in food, not even in baby food. Fresh strawberries in January in central Canada are awesome, but at what cost, to long term health? No one knows. There is sadly, no agency that over sees that for consumers.
