I found this article on "The Reptile Report" and thought I would post a small section of it and offer a link to anyone who wants to read the full article.

"APPA’s 2009 survey indicated that there were approximately 11,000,000 reptiles living as pets in the U.S. Nineteen cases of salmonellosis. Eleven million reptiles. That means that less than one thousandth of one percent of the pet reptiles in this country were a source of laboratory confirmed salmonellosis in 2009."
