Salmonella - Statistics and Incidence Rate

Salmonellosis is a bacterium that is passed on through contaminated food. The most common foods that can pass on infection if not properly cleaned include meat, poultry, eggs, milk, and raw fruits and vegetables.

Symptoms of salmonellosis include fever, headaches, chills, and diarrhea. Most people with the infection will not need any treatment, but it can be treated by antibiotics.
