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.
