Does all food poisoning result in vomiting?
A. No, reasonably little of it results in vomiting. Diarrhea and abdominal cramps are much more common symptoms of food poisoning. Having three or more episodes of diarrhea in an illness, and having bloody diarrhea are good indicators that one has been poisoned. Vomiting is a much more prominent symptom of staphylococcal food poisoning, however.
