Fushou snail, can you eat it?
Some citizens said,
Many fish ponds have Fushou snails.
Is Fushou snail poisonous?
Can I eat it?
One accidental ingestion
She had 6 lumbar punctures and miscarriages
At the end of July 2017, some netizens posted about their experiences, and it is still shocking to recall today.
She was traveling in Yunnan at the time, during which she ate the local Erhai field snail. After I went back, I developed symptoms such as fever and leg pain. Because she happened to be pregnant, she mistakenly thought that she was overworked and didn't care much.
Two weeks later, her condition deteriorated dramatically, and she began to have a high fever, unable to stand, sleep, or even open her eyes.
In the following days, she did 6 waist punctures, ate more than a dozen boxes of insecticides, and hung 300 bottles of water, because of hormones and drugs, which caused facial and body deformation, and finally had to terminate pregnancy.....
The culprit that caused all this was the "field snail" she had eaten before.
Fushou snail is extremely lethal
The tragedy never stopped
Is Tian Luo so scary? Of course not! Because what she ate at that time was not a normal field snail, but a frightening "Fushou snail"!
In May 2006, more than 160 people in Beijing became infected with Guangzhou roundworm after eating Fushou snails in restaurants, which became a major public health emergency in Beijing.
It is also because of this incident that many places in the country began to ban the sale of Fushou snails, and everyone gradually realized the danger of Fushou snails.
But Fushou snail and field snail are too similar, people are difficult to distinguish, so only 3 years later, Fushou snail climbed to the table again, because the tragedy brought by Fushou snail was staged again.
In 2020, a 7-year-old boy experienced frequent headaches and vomiting, and no cause was diagnosed in many hospitals. After high-throughput sequencing of cerebrospinal fluid, intracranial parasitic infection is diagnosed.
The culprit is the Guangzhou tube roundworm in the Fushou snail.
What is The Guangzhou Tube Roundworm
Guangzhou tube roundworm is a parasite that can cause zoonotic parasitic diseases.
Its ultimate host is a mouse, and the intermediate host includes brown cloud agate snail, Fushou snail, slug (i.e., slug), etc., and man is an abnormal host of Guangzhou tube symbiodia.
According to relevant studies, the body, excrement and mucus left by crawling in infected large snails will contain larvae of Guangzhou tube strong nematode.
People can be infected with Guangzhou tube roundworm through the following ways——
Raw or semi-raw food on infected snail meat
Wounds and mucous membranes are in close contact with infected snails
Eat salads, fruits and vegetables, and water contaminated with infected snails
After infecting the human body, Guangzhou Strongyloides can migrate between various organs of the human body, invading the central nervous system, lungs, eyes, etc., causing meningitis, meningoencephalitis, visual damage and even blindness.

However, although the Guangzhou tube roundworm is terrible, as long as we do the following points, we can stay away from it -
Do not eat raw snail meat
Avoid direct contact with the excrement, mucus and tissues of the "big snail" from broken skin and mucous membranes
Pay attention to clean your hands after contact with brown cloud agate snails
Pay attention to the isolation of snails from food, and avoid snail contamination of vegetables, fruits, salads and other foods
A Fushou snail has a thousand worms
Native to the Americas, fushou snails were introduced to the mainland in the 1980s as edible and economical snails, and quickly adapted to the local environment of the continent, causing harm to the ecological environment of the region.
In a warm, humid natural environment, they are incredibly reproducing, and each snail can spawn in large numbers many times a year; adult snails can survive in a dormant manner even in the harsh conditions of no water and no food.
Experts such as Dai Qingming, a researcher for agricultural machinery promotion at the Agricultural and Rural Bureau of Hanshou County, Hunan Province, said that in recent years, the density of juvenile Fushou snails in rice fields with high incidence of Fushou snails can exceed 100,000 per mu. Some localities have normalized the work of killing and cleaning up Fushou snails, and the task of prevention and control is very heavy.
Liu Zhijun, a major grain grower in the emerging community of Canggang Town, Hanshou County, said: "Last year, more than 170 mu of land in my family had a Fushou snail disaster, and some rice fields could find 20 snails per square meter, and in a few days they could eat all the grass seedlings in the field. ”
At present, Fushou snail has been listed as one of the major dangerous agricultural invasive alien organisms, not only the "killer" of crops and aquatic organisms, but also has a greater lethality to human health.
Some experts have conducted experiments on Fushou snail and found that the parasites in a Fushou snail can be as many as 6,000, and after being uncooked and eaten, it can be lightly feverish and diarrheay, and heavy is life-threatening.
With the rise in temperature, the phenomenon of Fushou snail flooding has recently appeared in many places in Guangdong, and disease control experts remind that for Fushou snails, do not easily touch them.
Qiu Weiwei, deputy chief of the Parasite prevention and sanitize Section of the Huizhou Municipal Center for Disease Control and Prevention in Guangdong Province, reminded that try not to let children touch and play with Fushou snails, and there are many bacteria, viruses and parasites in the external environment.
Fushou snail and field snail, silly can't tell the difference?
There is a folk proverb - Qingming snail race fat goose. The snail meat is strong and full of meat, which is a delicious dish on the table, especially the night market.
The appearance of Fushou snail and field snail is similar, and some consumers are difficult to distinguish, and mistakenly eating Fushou snail as a field snail will lead to tragedy.
In fact, there is still a certain difference between the two:
From the perspective of size, the adult Fushou snail is much larger than the field snail;
From the color point of view, the color of Fushou snail is yellow, while the field snail is bluish brown;
In addition, the tail of the field snail is vertebral in shape, and the cap head is round, while the tail of the Fushou snail is very short, the cover head is flattened, and the overall shape is disc-shaped.
Don't be silly anymore

Can you tell the difference between a field snail and a Fushou snail?
Forward it to family and friends!
Watch out! These little flying insects are appearing in swarms again!
Recently, there has been heavy rain in Guangdong
Last night, this rainstorm "blew up" flying insects

fly! ant!
(also known as the yellow-winged termite)
According to Guangzhou netizens @ hmm huh huh:
Bugs so many that the scalp is tingling,
As soon as the door is opened, it rushes in like a dam discharge!

Popular Science: Know the flying ants
Chinese scientific name: Yellow-winged termite
Also known as: large water ant, yellow-winged giant mantis, etc
Yellow-winged macrotera termite colonies reproduce as primitive king and queen spawners, and do not produce complementary reproductive ants. Nesting at a depth of 1-2 meters underground, every April to June, winged breeding ants breed in groups, generally flying 5-10 times, mostly flying out of the nest in the evening before and after sweltering heat or heavy rain, flying short-term flight, de-winging, pairing, and then planting a new nest in the appropriate place.
Termites prefer to nest in warm, humid places, scraps of paper, clothes, wood, trunking, wires... Can become their "cuisine". If the room is not disturbed, they will develop rapidly, and they can build a big nest in a year or so.
Flying ants usually refer to termites before their wings fall off, and when the flying ant colony flies, it is the time when the termites are breeding.
What if the big water ants flew home?
Never use pesticides!
Precautions quickly learn ↓↓↓
1. Strictly guard against death! Close the doors and windows, even the door seams do not let go, the window seams and door seams can be glued to prevent flying ants from flying indoors.
2, light and water method! Put a basin of water in the room, turn off the lights, and turn on only the small lights to illuminate the water.
3. Use poison carefully! Never use pesticides. Because although it can kill the flying ants after treating with insecticides, it also destroys the passage of the flying ants. In this way, the flying ants have not been completely eliminated, but they have opened up new channels and caused greater damage, which will bring inconvenience to the control of flying ants.
remind:
Close the doors and windows
Windows, door slits
Can't let it go
If the family is often hygienic, remove debris
Maintain a ventilated and dry environment
will destroy the reproduction of these termites
These ingredients must be cooked
Common ingredients such as yellow eels, crayfish, freshwater fish, and hot pot meat, which are not cooked and eaten, are also at risk of contracting parasites.
