Cleanliness..........Always wash your hands kinda simple but I think that would be the best advice. A wild caught snake I think would be fine as a pet people do it every day, though alot may not admit it.......it happens. If I was to briing in a wild caught snake into my collection it would be quarantined for awhile and a fecal exam by a vet. Then it would still spend some time by itself. I think you would be fine to handle the snake in question as long as you practiced common cleanliness.Good luck.
