Well, even though I know you can get salmonella from snakes, I don't really give it a second thought.
I handle my babies regularly, give most of them kisses and nibbles when I hold them. I've never gotten sick from one.
Now, granted I don't make it a habit to lick my snakes or something weird like that, I just figure if it's going to happen it's going to happen and I don't fret about it. I do of course wash after cleaning tanks and feeding, but other than that I'm pretty hit and miss.
On another note, I've gotten sick dozens of times after eating out at a restaurant and occasionally eating at a friends house. So, which one do you think worries me more ?
