Symptoms of ciguatera poisoning?

summary

Cigua poisoning, also known as cigua poisoning, is a kind of food poisoning caused by poisonous fish in tropical and subtropical coral reef developed waters. At first, it was named after the poisoning caused by human eating a kind of marine mollusk named "cigug" in the Caribbean. Now, the poisoning generally refers to the poisoning caused by ciguatoxin (CTX), hedgehog and toxin (MTX) and parrot toxin (STX).

Symptoms of ciguatera poisoning?

The symptoms of cigua poisoning are similar to organophosphorus poisoning: some victims begin to feel sharp pain in their lips, tongue and throat, and then numbness occurs in these places; In other cases, the first symptoms are nausea and vomiting, followed by dry mouth, enterospasm, diarrhea, headache, collapse, chills, fever and extensive muscle pain.

The symptoms can last for several hours to several weeks, even several months. In a few days after the symptoms appear, sometimes death occurs.

At present, at least four toxic substances have been isolated from ciguatoxin, maitotoxin and scaritoxin, which have different molecular weight and chemical properties

matters needing attention

Immunoassay is more sensitive than bioassay, but not all ciguatoxin have the same immune response, and the immunoassay of single toxin can not represent the detection of all ciguatoxin fish. In addition, heating or freezing can not destroy the toxicity of ciguatoxin fish, At present, there is no effective method to prevent ciguatoxin.
