Observing the symptoms [2] is usually sufficient to diagnose gastroenteritis. Then a food-borne illness is confirmed if the cause can be traced back to a contaminated food.
A coproculture (culture of human stools), the direct detection of the microorganism in the stool or a blood test often make it possible to identify the microorganism [3] responsible for the food-borne illness.
