Salmonella is no more prevalent today than it was 20 years ago, or even 200 years ago for that matter. The bacteria that causes salmonella (e. coli) lives in the soil. It is found nearly everywhere. It "blooms" in the immune-compromised person and causes a salmonella infection.
Reptiles can and do carry e. coli but so do nearly every other animal - including us. The risk of salmonella came to the forefront when baby turtles were popular in the pet trade in the 1970's or so. Many people bought these baby turtles as pets for young children and the children would frequently put them in their mouths (where were all the parents?? I sure wouldn't let my kid put a turtle in their mouth.....). It was what prompted that legislation (sorry it's late and I can't remember specifics at the moment) that led to disallowing the sale of turtles under 4" unless it was for "educational" purposes.
It's not a good idea to kiss your reptiles, although nearly all of us have (guilty!!). And it is wise to wash your hands after handling - especially after cleaning cages and/or feeding. But this is really more a matter of good hygiene than a fear of contracting salmonella.
So, no, I don't believe salmonella is a real problem with captive bred reptiles.![]()
