I think locusts are a great food, at one time I used to breed migratory locusts in large amounts and all of my frogs loved the various sizes. One thing I have seen people saying is that they don't bite, I can assure everyone they can, I have, on rare occasions, had adult locusts draw blood from me. The only other problems I have come across is locust allergy, some people develop this after long exposure to them, I work in a school and my lab technician is no longer able to be in contact with them, and they do make a mess of planted tanks
