Salmonellosis is a bacterial infection that affects the intestines and occasionally the bloodstream. It is one of the more common bacterial causes of diarrhea. Most cases of salmonellosis occur in the summer months and may occur as a single case, clusters or outbreaks. Typhoid fever is a life-threatening illness caused by the bacterium Salmonella serotype Typhi.

Disease Reporting

Health-care providers and clinical laboratories are required to report cases and suspect cases of salmonellosis to local health departments within one working day of identification. Cases are subject to restriction on school and day-care attendance, food handling, and patient care for the duration of any diarrhea and/or vomiting. Cases of typhoid fever (Salmonella serotype Typhi) require special measures.

Reptile handling is a very common source of salmonellosis, a diarrheal illness that can be severe or even life-threatening. Unfortunately, most reptiles (including lizards, snakes, and turtles) carry Salmonella bacteria. The bacteria are shed in their droppings and easily contaminate their skin and environment.
