The most common treatment for simple food poisoning is simply supportive care at home with clear liquids to stay hydrated, and after vomiting or diarrhea subside, the gradual return to eating beginning with a bland diet (such as rice, bread, potatoes and milk).

The doctor should be consultedalled if the person has nausea, vomiting or diarrhea that lasts more than 2 days, a fever, dizziness or unconsciousness, or if the symptoms are occurring after recent travel to foreign countries, or if people who ate the same thing are also ill. A visit to the hospital should be made if the person experiences vomiting blood, a swollen abdomen, problems breathing, swollen joints, yellow eyes or skin, or sharp abdominal pain that lasts more than 15 minutes.
