[Seafood Talk] Toxic, deadly, and for which there is no specific antidote – such seafood must not be eaten!

The woven-patterned snail, commonly known as sea silk snail, sea snail, wheat snail, or white snail, is a **toxic aquatic organism whose harvesting, processing, and sale for consumption are prohibited. There is no specific antidote for poisoning! ! ! It is understood that the woven-patterned snail is widely distributed in coastal provinces such as Zhejiang, Fujian, and Guangdong. Its physical characteristics include a relatively pointed tail, with a slender body measuring about 1 centimeter in length and 0.5 centimeters in width. The textile snail contains paralytic neurotoxins, and its toxicity is higher during the spring and summer months. Consuming it can lead to poisoning; mild cases may cause symptoms such as dizziness, vomiting, and numbness in the lips and fingers, while severe cases can be fatal. The incubation period for poisoning ranges from as short as 5 minutes to as long as 4 hours. There is currently no effective treatment for food poisoning caused by Trochus.

Cases of poisoning resulting from the consumption of cowrie shells occur from time to time. **The Ministry of Health and Family Planning’s Announcement No. 13 of 2012 on Preventing Food Poisoning Caused by Cowrie Shells explicitly stipulates that no food production or distribution enterprise shall purchase, process, or sell cowrie shells.

Actually. . . The rugose cone shell is non-toxic in itself; its deadly toxicity is acquired from its environment of growth. There are mainly two sources of this toxicity: first, due to the frequent occurrence of red tides in recent years, the algae that proliferate in such conditions can produce toxins. When the rugose cone shell consumes these toxic algae, it accumulates these algal toxins, thereby becoming poisoned. During its growth process, it also accumulates certain neurotoxins, primarily \"paralytic shellfish toxins.\" Among these, \"pseudonervous toxin\" is one of the most toxic marine toxins known. A single dose of pseudonervous toxin found in a rugose cone shell can be fatal ； The second is tetrodotoxin, which is well-known to many; it is one of the most toxic neurotoxins found in nature. This toxin is heat-stable, and methods such as boiling, salting, or exposure to sunlight cannot destroy it. How to tell? Every summer is a peak season for food poisoning caused by Veronicella spiralis. There are many species of textile snails, making them difficult to distinguish! Currently, the rugose conchs available on the market are all caught in natural marine areas, and it is difficult to determine whether they are poisonous unless each one is examined individually.
