In all fairness, wasting food needlessly can have important environmental impact issues, and if the legal limits are well calibrated, getting the "allowed" dose of fungus might be a good thing from an immunological perspective. Heavy metals not so much...

Arguably, separating out grains, etc., that would be actually unsafe to eat is not really wasting food. Throwing out food that is perfectly edible is wasteful.
