Keep in mind when feeding wild caught food that most parasites are host specific. Being that Savs come from Africa and these grasshoppers are American, the odds of the sav conracting a parasite would be slim. My main concern would be feeding incects that come from areas where pesticides are used. Those could do some serious damage to the monitor.
Another thing to keep in mind is that whole food items are hands down the best foods for monitors. Those canned foods may be convenient and monitors will eat them because they are extremely opportunistic and will eat pretty much anything, but it really is not healthy for them. Things like mice, rats, chicken peeps, quail, insects, crawfish etc. (depending on the species) are by far the healthiest things you can feed monitors and is what any established breeder feeds his animals. For savs I would recommend sticking with the FT mice. You can order them in bulk online for cheap and they're just as convenient as canned.
