Thirty-three people (nine groups) ingested fish belonging to the grouper family; eleven people subsequently complained of muscle pain and muscle weakness of the neck, shoulder, hip and thigh 3 to 43 hours after the meal. Rhabdomyolysis was suspected based on the patients'symptoms and the results of blood examinations, and five patients were admitted to hospital. Fluid therapy was administered, and all of the patients recovered and were discharged from ospital on the 4th day of admission. A palytoxin-like substance was detected in the fish and was presumed to be the cause of the rhabdomyolysis. If patients with food poisoning complain of muscle pain and have no symptom of the digestive system, the possibility of poisoning by palytoxin or a palytoxin-like substance should be considered. Although such poisoning is commonly caused by parrotfish, other fish species may also carry these substances.
