A locavore is someone who eats foods produced "locally" (e.g., within 200 miles). But what would you call someone who obtains their calories only from operations they have seen and inspected with their own eyes?
It would take a little thought to put together the "rules of the game".
What constitutes having seen and inspected a place?
How much of the process must be witnessed?
What exceptions can be made? (Maybe flavorings, spices, herbs, salt, ...)
As a stunt, it should only count if you have done the inspection since the beginning of the ordeal, which would make the beginning quite an adventure.
For practical purposes, it might be kinder and gentler to allow a degree or two of separation:
buying food directly from someone who has seen the operation and represents it as something you can support (and is presumably willing in principle to allow you to inspect it for yourself if you wish). Or trading with a neighbor who went through the process themselves.
Ultimately the goal could be to have a robust web of trust where everything desired could be had from some source that someone known to you could personally vouch for.
