چکیده:

Objective: In this study, a case of Ichthyootoxism or egg poisoning is reported in the Cyprinid fish species Capoeta capoeta from West Azerbaijan of Iran. Fish egg poisoning is a public health hazard for European and Asian people. In Northwest of Iran, spawning of Capoeta capoeta occurs from April to Jun. Eggs are yellow in color, up to 1.5 mm in diameter.
Method and Materials: Fish were collected by net traps which placed in the Marmisho Lake. Nearly 500 kg fish were collected. The largest Capoeta capoeta hunted had 310ml total length and 400g weight.
Results and Conclusion: Eggs from one specimen formed part of a meal for S. Shiri about 1.8 of an ovary was eaten after neating and served as fried eggs. The toxic effects noted were nausea just one minute after ingestion of the first meal spoon. Frequent nausea without vomiting, abdominal pain, sever chest pain, were the symptoms. This victim aged 34 years and weight 70 kg, was hospitalized for 24 hours. Anti vomiting injections (methochlopramid, I.M. injection) were prescribed but nausea were continued for 16 hours and the victim suffered from sever chest pain. The presence of nausea without vomiting may be due to the victim had eaten no meal for lunch. Therefore, by ingestion of the first spoon, the ingredients were absorbed to blood system and nausea were continued until breaking off the toxicity. We have no evidence that Ichthyotoxism with Capoeta sp. Leads to death although deaths have occurred with the related family member Schizothorax. Cooking dose not always destroy the toxin eggs from all Cyprinid species in Iran. Raw consumption of them should be avoided, especially in the spring breeding season and the flesh thoroughly cleaned and cooked before eating.
