What is food poisoning?
Food poisoning might be described as a food borne disease. Food that contains a toxin, chemical or infectious agent (like a bacterium, virus, parasite, or
prion) and cause symptoms in the body are considered types of food poisoning by most health care professional. Those symptoms may be related only to the gastrointestinal
tract causing vomiting or diarrhea or may involve other organs
such as the kidney, brain, or muscle.
Typically most food borne diseases cause vomiting and diarrhea that tend to be short lived and resolve on their own, but
dehydration and electrolyte

resulting in 128,000 hospitalizations, and 3,000 deaths.
According to the CDC, in 2011, the most common foodborne
