It sure is a huge challenge! I mean, there’s no way mankind could feed themselves and survive WITHOUT THIS LAW, is there?
This is yet another unconstitutional power grab.
Maintaining a safe food supply falls into the category of "general Welfare." It is difficult to see how the free market could ensure a safe food supply, without a system in place to test food, without adequate science-based regulations and policies in place as a guide, or without a central clearing-house for information that must be disseminated rapidly to millions of people. Because in any system that depends on a free market reacting to a problem, people will needlessly get hurt or even killed by the time a problem is even discovered (if it can be identified at all).
I have no issue with the federal government fulfilling its constitutional duties. The problem I see is that legitimate constitutional functions are used as an excuse to cross over into tyranny (like forcing restaurants to stop using salt, even though it is a necessary nutrient).
