From the little I read in the Q & A section it is more government regulation and control that will do what most government regulation and control does - increase the cost of food and hurt the small farmer and farmers markets while doing little to do what it says it is going to do in protecting the food supply.
It sounds harmless and like a good thing to do but it is just more government overreach. It is the EPA of food.
