You are far, far, FAR more likely to contract Salmonella from your own food then from your reptile.

And if you are that freaked out, don't ever observe the kitchen of just about any restaurant, LOL.

Hand washing after cleaning of enclosure is important and I don't know why anyone would not do that, ick !

However, scrubbing your hands and arms with sanitizer every time you handle your BP seems excessive to me. I think if I was "that" worried about it, I would somehow get my snakes waste tested to see if there was even any salmonella present. They don't all carry it.

Cleanliness is very important. But it CAN be overdone and will cause your (and perhaps your pets) immune system to go haywire. Some people will use harsh products , and several all at once, continuously. It has proven to have the opposite effect of what one is trying to accomplish. Being healthy.

Again, not saying one shouldn't use proper hygiene. But there is no reason to be paranoid and sanitize "to the bone".
