They can still give you salmonella
So don't eat raw snake sashimi or sushi ;-) Eat yummy unagi or anago (sweet eel) instead. If you are more adventurous, go to expert licensed sushi master and try fugu (puffer fish / blowfish) sashimi.
The poison (tetrodotoxin may be up to 1200 times deadlier than cyanide) from one fugu may kill up to 30 people, but if the chef does his job right, the experience is sublime.
