ive never knowingly caught it, when i was 6-7 i used to catch garter snakes in my yard and eat directly after handling them all the time without washing my hands, the only time i'd wash was when they'd musk me (smells horrible), i did the same after handling my turtles (RES) and never got it, i would wait for my hands to dry but never wash them

and when it comes to aquatic turtles, they are a supposed breeding ground for salmonela, but since they always only poo in the water (from what ive seen at least), and theyre stuck in a fish tank, it makes perfect sense, they dont really have being clean as an option, unless the owner is constantly cleaning
