There are many warnings about sea rainbow weavers. What are the reasons?

The paralytic shellfish poison contained in the sea rainbow has exceeded the safety limit by more than two times, and it can easily cause poisoning if eaten. Haihong, also called mussel or mussel, is a common edible shellfish in northern China. It can be cultured artificially, so it produces a lot and is a kind of seafood that people often eat.

paralytic shellfish poisoning is one of the most toxic toxins, and its toxicity is equivalent to tetrodotoxin. It consists of more than 2 kinds of toxins produced by dinoflagellates with different structures, which can grow in both tropical and temperate waters. This toxin is soluble in water, stable to acid and easy to decompose and inactivate under alkaline conditions. It is also stable to heat, and general heating will not invalidate its toxicity.

because of the different waters and seasons, the algae eaten by the snail may or may not be toxic, and the toxic content is also different.

Oncomelania is a common animal in the southeast coast of China, belonging to mollusca, Gastropoda, Narrow Tongue and Oncomelania. People in Putian, Fujian and other areas especially like to eat it. It is said that it is easy to be sucked out of the snail shell after being cooked, and its taste is tender and smooth, and some people are even addicted to food. However, there is indeed a huge food safety risk here. The snail was originally non-toxic, but it would not work if it drank dirty water.

The tail of the snail is sharp and slender, with a length of about 1 cm, which is almost the same as that of a fingernail. It is very small and its color is mostly gray-black. This kind of screw carries a paralytic shellfish toxin, which will cause neurological paralysis symptoms after eating, and the mortality rate is high.

The snail itself is nontoxic, and its fatal toxicity is acquired in the growing environment. Because the snail feeds on toxic algae, it enriches and accumulates some neurotoxins in toxic algae and is poisoned, so it is particularly easy to cause food poisoning after eating. Snail contains tetrodotoxin, which is one of the most toxic non-protein neurotoxins in nature. It can prevent the occurrence and conduction of nerve impulses, make neuromuscular lose excitability and cause acute poisoning. After poisoning, patients have symptoms such as numbness of tongue and lips, headache, vomiting, and increased heart rate. In severe cases, they will die due to respiratory failure.
