I believe the quoted chance of a CBB herp having salmonella is 1% and that is mostly turtles...? That being said, we have designated areas where reptiles can be - their enclosure, the table assigned to their stuff and the human handling them. We wash after handling any reptile. Herp food/gutload stored in human fridge/freezer are double bagged- outside clean hands, inside herp'ed hands. Since my geckos are fond of playing Climb the Girl, I often end up changing clothes and or taking a shower if they are especially troublesome.
Now part of this is because I have a poor immune system and don't want to take any chances that my reptiles have anything... however, up against a wall if you were to put into law "You can keep it if you lick it" reptile ban, I believe I'd be just fine. In the meantime, not worth the risk for just a little bit of vigilance.
(Of course I don't condone licking reptiles, but it makes my point.)
