Bug droppings are bad. You don't want them in food. Bugs themselves are usually quite nutritious.
But then, when I was taking entomology, I ate all sorts of interesting things someone in our class cooked up as part of a project researching using insects to increase the nutrition of some foods. "Jimminy Bread" was...interesting. Good, but you really didn't want to look at it closely. Lots of caraway seeds to mask other...components.
