We teach very little about this subject in schools on either continent. We can't leave our education to the tabloids. Precaution must of course be a central feature of any regulatory system. But I fear its elevation to a political principle could create a false public expectation that food risks can be cut to zero. The real issue is how much risk and uncertainty is acceptable and still considered safe.
Some people claim they cause brain tumors.
No, we made a judgement about risk and uncertainty and got on with our lives. The U.S. system is not perfect. It can't be. But when problems arise, public fears do not grow out of control because they trust that the authorities are doing the best and not covering up. That is because the system is open, reacts quickly and does not promise absolutely zero risk.
