The transport of ciguatoxin: a case report.

Ciguatera fish poisoning has been responsible for as many as half of all food poisonings in the United States due to fish. Because the initial symptoms often include gastrointestinal symptoms, such as nausea, vomiting, diarrhea, and abdominal pain, patients may be discharged from the Emergency Department with a diagnosis of "acute gastroenteritis," only to return soon thereafter. This is a case report of such a patient who was evaluated and discharged only to subsequently return because of worsening of symptoms.
