Raw eggs. Chicken. Food. All of that is more likely than a reptile.
That first thread posted by Slim has a commenter talking about a couple of relatives getting sick from a friend's herp room, mentioning that the herper kept monitors as well as snakes.
What do monitors eat? Eggs. Raw meat.
What is a big potential carrier for salmonella? ...Hmmm...![]()
Lastly, salmonella is carried through feces, in the intestinal tract. That's why eggs are such big carriers of the bug - they pass through the same exit as the poop does in chickens! So as long as you keep your cage(s) clean, and don't put poop in your mouth, or the snake (they do crawl through poop if it's in front of them), you're unlikely to catch salmonella from your reptiles.
Glad your girlfriend is feeling better!
