Food poisoning associated with Kudoa septempunctata.
BACKGROUND
Kudoa septempunctata is a recently identified cause of food poisoning. We report three cases of food poisoning due to ingestion of this parasite.


METHODS
Among the 358 people exposed during the same catered meal, 94 (including our 3 patients) developed vomiting and diarrhea within 1-9 h after ingestion of raw muscle from contaminated aquacultured olive flounders (Paralichthys olivaceus). These symptoms occurred frequently but were temporary; only 1 patient was hospitalized for dehydration and was discharged 2 days later.


CONCLUSIONS
In Japan, cases of food poisoning due to eating olive flounder have increased during recent years. This increase should prompt heightened awareness among clinicians diagnosing food poisoning.
