Digestive Diseases: Food Poisoning
Food poisoning is a common, yet distressing and sometimes life-threatening problem for millions of people in the U.S., and throughout the world. People infected with foodborne organisms may be symptom-free or may have symptoms ranging from mild intestinal discomfort to severe dehydration and bloody diarrhea. Depending on the type of infection, people can even die as a result of food poisoning.
More than 250 different diseases can cause food poisoning. Some of the most common diseases are infections caused by bacteria, such as Campylobacter, Salmonella, Shigella, E. coli O157:H7, Listeria, and botulism.
