Nowadays, the standard of living is getting better and better, even if it is not a coastal city, you can often eat all kinds of seafood, especially for many "wine friends", when they get together, the most favorite is to come to a plate of fried snails, not only under the wine, but also to enjoy the mouth.
However, what many people don't know is that not all snails can be eaten, if one day, everyone encounters the following snail, we must refuse to eat it, because it is extremely toxic, it is possible to eat only one, it will be killed.
<h1 class="pgc-h-arrow-right" data-track="3" > so, what is this snail? How toxic is it? </h1>
This snail is a kind of small snail that looks very similar to the "sea cone" we usually eat, its scientific name is the weaved snail, which is also known as the sea snail, white snail, small yellow snail, etc. In some places, its characteristics are that the individual length is about 1 cm, the width is about 0.5 cm, the tail is very pointed, the overall slender, it looks very similar to the sea cone cone, but the sea cone cone is not poisonous, and the weaved snail may kill people when eaten.
From the distribution point of view, the weave snail in China is mainly distributed in Guangdong, Zhejiang, Fujian and other southeast coastal areas, they are hidden in the bottom of the reef and sediment, every year around the Dragon Boat Festival, is the best season for this snail to appear in large quantities.
Because some provinces on the southeast coast, especially in the Fujian region, many places have the habit of eating textured snails, which also leads to the occurrence of snail poisoning, and although the National Ministry of Health has long banned it, there are still people who are desperate to take risks.
From the perspective of toxicity, the study found that the toxin in the texture snail is "stone room hatoxin", its toxicity is about 80 times that of cobras, when eating texture snail, even if only about 0.54 mg of "stone house hatoxin" is ingested, it will also be fatal.
And "stone room hatoxin" poisoning after the onset of the disease is very fast, generally in about 5 minutes after eating it will be sick, and the larger the intake, the higher the fatality rate, mainly nerve poisoning, the early stage will appear vomiting, numbness and other symptoms, if you can not get timely assistance, then, the serious will die.
This is not alarmist, look at a few examples: in 2005, a fisherman in Xiapu County died of poisoning after eating a weave snail; in 2015, a boy in Putian was poisoned after eating a weave snail, and became a vegetative person at the age of less than 3 years old.
There are many similar situations, therefore, as early as 2012, the Ministry of Health has banned the processing, sale and consumption of textured snails, but because many places have had the habit of eating textured snails since ancient times, for example, in the Putian area of Fujian Province, in the past, every year during the Dragon Boat Festival, coastal residents would eat textured snails for the festival.
Therefore, although it has been banned for nearly 10 years, it is still repeatedly banned, which is also the main reason for the frequent occurrence of snail poisoning.
A new question arises here: since the snail has been eaten by people as early as ancient times, why has the poisoning of the snail only begun in recent years?
<h1 class="pgc-h-arrow-right" data-track="22" > is it only modern people who eat textured snails to be poisoned? </h1>
In fact, the texture snail is now more and more toxic, and the ancient people eat or modern people eat, mainly related to the texture snail itself in the marine environment, the severity of pollution problems.
The study found that the snail itself is non-toxic, and the reason why it carries a deadly toxin in the body is because in the process of growth, it absorbs the toxic substances in the surrounding seawater, so that these toxic substances continue to accumulate in the body of the snail, so that the greater the pollution problem, the greater the toxin in the snail.
For example, we all know that in recent years, the problem of marine pollution has become more and more serious, especially the discharge of industrial wastewater, which will cause eutrophication in the ocean, and many sea areas will have red tides in different seasons.
For example, in July this year, there was a red tide in the coastal areas of Fujian, and the local fisheries department also issued an emergency announcement to remind everyone not to eat seafood during the red tide, even if they eat, they should also do a good job of "picking and choosing" to avoid poisoning caused by excessive toxins in seafood.
Because in addition to the texture snail, many shellfish will also appear toxins due to marine pollution problems, such as mussels, during the red tide, if you eat poisonous mussels, then the fatality rate is as high as 15%, and in recent years, because of the red tide pollution problem, every year in many parts of the world, there will be incidents of shellfish poisoning during the red tide.
Therefore, the textured snail, which is more likely to carry toxic substances, is prohibited from being used, because the marine pollution problem in the southeast coastal area of China has become more and more serious, and the frequency of the red tide phenomenon is also getting higher and higher, which leads to the texture snail carrying a large number of toxins, which is constantly poisoned in the process of growth, and eventually becomes toxic food.
In the past, the reason why ancient people ate texture snail poisoning was relatively small, in fact, it was not so serious about the problem of marine pollution at that time, and now the pollution problem is getting more and more serious, and naturally it needs more attention.
