In March this year, a 10-year-old boy in Zhongshan, Guangdong began to experience symptoms of persistent and repeated fever and headache , and did not improve after treatment in many hospitals.
After multiple transfers to the hospital, the doctor found an abnormal signal in the child's head MRI imaging . When asked about the parents and children in detail again, the parents said that boys like to play with snails , especially when it rained for several consecutive days, a group of calm and leisurely snails on the roadside were the boys' favorite.
Finally, the boy was diagnosed with Guangzhou Tube Eosinophilic Meningoencephalitis. After deworming and anti-inflammatory treatment, the boy has recovered.
Doctor said that he (boy) is a third-stage larval infection, and the parasite can develop into the fourth-stage, fifth-stage larvae, or early adult stage. After adults reproduce, it will damage our functional area, and the most serious possibility of causing disability and death of .
A parents once reported that after catching snails,
One-third of students in a class take leave due to illness
At a certain WeChat group, a parent once said that school teachers arranged for children to catch snails before, but parents and children often cannot distinguish the difference between ordinary snails and big snails, and children are more likely to be attracted by larger snails. As a result, after catching these big snails, the child has a fever, and has a fever to 40 degrees. What's even more terrifying is that at the same time, one-third of the children in the class took leave due to illness.
This is not an ordinary snail, this is African big snail
One of the first batch of 16 foreign invasive species in my country!
This big snail that has become a disaster in Guangdong after the rain is actually not a "local" snail in Guangdong.
They are Brown cloud agate snail (yes, snails and snails actually belong to the same family) . People are used to calling it African big snails.
Its hometown is in eastern Africa and is The largest snail in the world .
In China, Xiamen University is the earliest place to discover African giant snails in China with written records.
In the first half of the 20th century, an overseas Chinese accidentally entrained the eggs and young snails of the large African snails into plants transported back to China from Singapore. After that, the large snails began to reproduce in Xiamen and further spread to other regions.
In this way, the African giant snail has become one of the first 16 alien invasive species in my country.
This "big beast" eats everything without any ambiguity. All kinds of vegetables, crops, plants, and trees in the fields are all swept away. Wherever you go, no grass grows.
It has been listed as a second-class quarantine pest in my country.
Why are there so many snails after the rain?
African snails usually only dare to move in wet places in the grass, and they may die of dryness on the road or sunburn. It dares to climb everywhere after it rains.

This kind of snail is best not to touch
One one has more than 100 insects
The most terrifying thing is that the African snails born in the wild are very dirty!
Their mucus or feces may carry a lot of parasites and pathogens, especially Guangzhou Tube worms, which can cause meningitis and encephalitis and other diseases.

Children have low immunity. If you are curious, you will be more likely to get caught!
After Guangzhou Tube Circular Nematode enters the human body, it will parasitize in the human central nerve or cerebrospinal fluid , which may cause fatal meningitis.
In Shenzhen, the infection rate of Guangzhou cymbidium nematode is 31.0%, with an infection degree ranging from 89.2-154.2 bars/snail.
In other words, There are probably 100 such parasites on an African snail.
In addition to the African snail, Fushou snail , slug (i.e. slug ) is also the favorite intermediate host of Guangzhou Tube Circular Nematode, and their final host is a mouse.
3African snails should not eat
French baked snails is not this breed
African snails in the wild cannot be touched, and they cannot be caught and eaten at home, and they cannot be cooked!
studies show that spiral lungs are the organ with the highest density of infection in larvae, and more than half of the larvae in the spiral body are hidden in the lungs.
Many people see big African snails with a lot of meat, and think French baked snails are made of this thing.
In fact, French baked snails are not African snails, nor are they common snails in paddy fields, but the edible variety white jade snail . Moreover, it must be a white jade snail in a controlled environment of . must not be caught in the community or picked up in the paddy fields.
Therefore, not only should we not eat African giant snails, but even the organic vegetables crawled by snails must be thoroughly washed and cooked before eating-
- 1985, a family of nine people in Taiwan were infected with the parasite after eating the uncooked African giant snails, resulting in the death of 4 people.
- 1999, after 6 family of Taichung had eaten organic vegetables crawled by snails, all infected with Guangzhou Tube worms, resulting in meningitis.
"relatives" of the big snail should not eat
is also "toxic"
In March 2018, domestic and foreign media reported that a 19-year-old rugby player in Sydney, Australia, swallowed several slugs because he was "showing handsome" at a party. was infected with Guangzhou Tube worm, and was paralyzed. He had been withstood for 8 years and died of complications.
