Just an FYI, although rare, salmonella can be passed through other methods besides the consumption of feces. If a reptile has salmonella and defecates, then it can be transmitted through a variety of ways. If the infected feces touches the reptile, and someone handles the reptile, it can be transmitted that way. Also, it can be found in the enclosure itself, as that is where the animal usually defecates. Proper handwashing after handling any reptile is necessary. And just another good reason to throughly clean and disinfect a cage after the animal defecates.
