The following are some of the salient features of food poisoning:
Acute diarrhea in food poisoning usually lasts less than 2 weeks. Diarrhea lasting 2-4 weeks is classified as persistent. Chronic diarrhea is defined by duration of more than 4 weeks.
The presence of fever suggests an invasive disease. However, sometimes fever and diarrhea may result from infection outside of the gastrointestinal tract, as in malaria.
A stool with blood or mucus indicates invasion of the intestinal or colonic mucosa.
When vomiting is the major presenting symptom, suspect S aureus, Bacillus cereus, or Norovirus.
