The tail tip is slender, the snail is about 1 cm long and 0.5 cm wide, and the shell surface often has 1? 3 purple-brown or red-yellow spiral bands, light yellow body. Snails contain tetrodotoxin, which is easy to cause food poisoning. The announcement of the former Ministry of Health 20 12 clearly requires that no food production and business operation entity may purchase, process or sell snails. At present, it is the peak season for the sale of edible snails. Recently, the national food safety risk monitoring found that snails still exist in the market, and the samples were found to have high tetrodotoxin content. Tetrodotoxin poisoning can cause dizziness, vomiting, numbness of lips and fingers, and even death in severe cases. The incubation period of poisoning is generally 10 minutes to 3 hours. Toxins are stable to heat and cannot be destroyed by cooking, salt and sunlight. At present, there is no specific drug to detoxify.
