Whenever you see the unions (or any 'association') push for a national goal, you have to drill in to find the angle. In this case, it is hiring more unionized safety inspectors. Now, I am not going to comment on the mind-set of inspectors, but they tend to be rather average. They would have not picked up on the latest Listeria mechanism. In fact, I can't think of any food incident that would have been prevented by unionized inspectors.
What they need are thinkers at the high level of decision making. This, unfortunately, is the realm of political toadies. Nobody is thinking about this, because their solutions would conflict with the political expedience of the day.
