Can you give me a source on what the total economic costs are (including opportunity costs) per reduced cases of e coli due to licensure of eateries? I have spent years in Asia and never heard of it. In the states I know of a few cases of it happening. Not from food trucks or otherwise unlicensed places. I'm all for prudent regulations. I'm not suggesting we abolish the FDA. However, I think government interfering in me and a lemonaide stand, or food truck being, able to voluntarily exchange value is far across the line into the absurd.
