Eat carefully!Fish innards may contain ciguatoxin

Ciguatoxin belongs to neurotoxins, colorless, tasteless, fat soluble and insoluble in water, heat resistance, not easily destroyed by stomach acid, It is mainly found in the internal organs and muscles of tropical coral fishes, especially in the internal organs. It affects the human gastrointestinal tract and nervous system.The symptoms of the poisoning are similar to those of organophosphate poisoning, and some victims begin to feel pain in their lips, tongue and throat, and then become numb in these places. In other cases, the first symptoms are nausea and vomiting, followed by dry mouth, intestinal cramps, diarrhea, headache, fever, and muscle pain. Toxic symptoms can last for several hours to weeks, even months, severe poisoning can lead to death.


According to Marine biometric experts, more than 50,000 people in the world are poisoned by the ciguatoxin each year, but only 10 percent of poisoning incidents are reported by the public. Ciguatoxin poisoning in recent years, has a tendency to spread, the reason is the marine pollution and global warming poses a great damage to coral reefs, and coral reef is the habitat of most tropical deep-sea fishes.


Scientists say that the greenhouse effect makes the ocean temperature rising, at the same time, human emissions of toxic waste in the ocean more and more, these two factors make the coral reefs destroyed, the algae that contain ciguatoxin grow thickly. Small fish that live near by coral reefs live on algae. Fish such as grouper and barracuda, which humans eat for a long time, feed on these fish, so the ciguatoxin pass through the food chain to the human body.


Although scientists already know that the cause of the damage of ciguatoxin is global warming and pollution, public health officials are still facing huge challenges, it is hard to know which fish with ciguatoxin. Fortunately, the currently successful application of the ciguatoxin enzyme-linked immunoassay kit (GLORY SCIENCE CO., LTD, Product NO.: I4441 ) has been used for quantitative testing of the residue in fish, shrimp and meat tissue samples. However, scientists have not yet found an effective way to treat the poisoning of ciguatoxin. In addition, doctors also lack effective equipment to diagnose the poisoning of ciguatoxin, which is often misdiagnosed as other diseases in many areas.


Experts caution that, for the sake of safety, don’t eat the guts of fish. It accumulates in the fish’s liver, bile, eggs and other internal organs, and removing the internal organs is a good way to avoid poisoning. In addition, the method of heating, refrigerating and drying can not remove ciguatoxin. It is important to note that you should avoid drinking and eating peanuts or legumes at the same time, so as not to aggravate the poisoning.
