Meat is on the inside of the animal, so proper preparation is important in making sure external contaminants aren't introduced.

Insects, on the other hand, are consumed whole. There's no getting around the fact that you are eating the part of the thing that walked and wallowed in it's own shit.

Pupae are an interesting exception, perhaps, though for the most part when talking edible insects I suspect people think crickets and the like.
