it's safe, don't worry. in france there are breads and cookies with insect larvae in them, can't remember which, that are sold as is. apparently the arab population over there is fond of them as it is chiefly sold to them, or so the baker told me while i was there. never tried it myself, but he told me that there's no real taste to them, maybe slightly sweet if anything, and that in white bread you can't even see them sometimes if they are small enough. the bread has higher protein though, so it's healthy for you.
