Suruga Bay
A food poisoning outbreak of 26 cases in the Ganyudo area of Suruga Bay, Shizuoka Prefecture in Japan in September 1965 was traced to ingestion of the toxin surugatoxin (SGTX), named for Suruga Bay. SGTX is contained in the mid-gut digestive gland of the Japanese ivory mollusk, "Babylonia" "japonica", which is used as an ingredient in sushi and sashimi. The food-poisoning patients reported a variety of symptoms, including visual disorders, speech disorders, lazy eye amblyopia, pupil dilation (mydriasis), abdominal distention, dry mouth, numbness of lips, constipation, and vomiting.
