Salmonella Food Poisoning: Causes, Symptoms, Treatment, Recovery Period

What is Salmonella Food Poisoning?

Salmonella Food Poisoning is a pretty disabling and annoying pathological condition that normally occurs due to eating contaminated food. The food that the affected individual eats is usually contaminated by animal or human feces which tend to carry the bacteria called as Salmonella. Salmonella Food Poisoning are normally found when people eat foods made of poultry items like eggs or meat, although this bacteria may also contaminate the normal fruits and vegetables that we take on a daily basis. Some of the common food items that can be infected by the bacteria Salmonella and cause Salmonella Food Poisoning are undercooked eggs, raw milk, contaminated water, and raw meat. The bacteria is divided into 2 type, one is the non-typhoidal type which is quite common and the other one is the typhoidal type of bacteria which may cause Typhoid which is potentially dangerous and may require extensive antibiotic treatment. The specific bacterial form causing this condition is called the Salmonella Typhi bacteria.
