Keep in mind that for people with compromised immune systems, salmonella is much more dangerous than "healthy" people. My daughter was recently diagnosed with Type 1 Diabetes and we had to drastically change how (and if) she handles my snakes. At first, we said absolutely no touching reptiles and after a while, she does hold them, but we are super careful about cleanliness and hand washing. Its not that she is more likely to get salmonella than me, its that for her it is potentially deadly. I'm not willing to take that chance for sure, even though the chance is very, very small.
