Salmonella is a member of the Enterobacteriaceae family and is always considered a pathogen when isolated from food products or humans. The disease caused by Salmonella is generically called salmonellosis and can range from bacterial diarrhea to septicemia. Bacterial diarrhea salmonellosis infection is generally foodborne, usually reaching humans through contaminated eggs or improperly cooked poultry products. Fowl harbor many species of Salmonella in their gastrointestinal (GI) tracts, which can result in contamination if handled improperly. S. typhi, the cause of typhoid fever, differs from most Salmonella spp. in that its reservoir is human rather than animal. The organism is spread from person to person via the oral-fecal route.
