Scombrotoxism - Ciguatera - Mytilism - Tetrodotoxin poisoning – Marine poisonings |
| Abstract |
In recent years significant progress has been made in the understanding of the numerous poisonings that can be caused by dangerous marine species. The most common syndromes are scombroid-fish poisoning (scombrotoxism) that is a reaction to high histamine production in some fish and ciguatera-fish poisoning induced by eating seafood contaminated with cinguatoxin produced by the dinoflagellate Gambierdiscus toxicus. Ciguatera is a major socio-economic problem in endemic areas where consumption of fish can be hazardous. Recent reports have described a number of less common syndromes that can quickly lead to life-threatening symptoms including tetrodotoxism (fugu in Japanese), clupeotoxism that occurs mainly after ingestion of tropical sardines, and palytoxicosis that occurs after ingestion of crabs contaminated by palytoxins. Carchatoxism and chelonitoxism due to ingestion of the flesh of sharks and sea turtles respectively are frequently reported as mass poisonings after sharing meals prepared with these large marine animals. A current source for concern is accumulation of emerging toxins in shellfish that could jeopardize marine aquaculture in several regions of the world. |
