From 1990 through 2012, there have been two human deaths resulting from exotic animal incidents (including reptiles):

2007 a woman died resulting from an incident with her wolf hybrids.
2001 a trainer died resulting from injuries sustained from a Bengal tiger.

During that same time period, there have been eleven injuries from exotic animals of all types; one of these incidents involved a large constrictor.

All of these incidents involved the animal’s owner, keeper or trainer.  Not one of these incidents involved any member of the public.
