I may have said this before, but I think the problem is two fold.
First, we do need some form of food handling knowledge from those who are feeding us. And of course we also need to be aware ourselves of safe food handling procedures when we feed others.
Second, and this is a tricky one. We are rapidly reaching a point of over sterilization.
I think it's possible that we can become too clean of a society, leaving us eventually more susceptible to food borne illness.
For example someone from south of our borders might be much more resilient due to greater exposure and higher immune levels from being exposed to things we are trying to irradicate.
And that is more than likely why people who travel to Mexico complain of getting sick.
But on the same note how could we possibly determine which food borne bacteria is acceptable and which isn't, and to control the amounts presented to us.
I hardly think popcorn and peanuts pose much of any threat when it comes to food borne bacteria, being that there is little to no moisture present for bacteria to thrive.
I guess this one boils down to principle, being that a law is requiring a food manager be present during the public sale of food items.
I see this instance of the scouts just falling under a blanket without regard to what is actually being served and the inherent lack of disease causing criteria.
