If you accidentally find a lot of "field snails" in the wild, will you be tempted to fish them home for a good meal?

Wild surprises
The "field snails" fished more than 20 and went home
Ms. Jing, a citizen of Yizheng, told reporters that her family lived in Yizheng Xupu, while her mother's family was in Zaolin Bay.
"Now the scenery in many places in Zaolin Bay is very beautiful, and I just want to take my children to see my mother on the weekend, and take a good look around Zaolin Bay, it will be an autumn tour." Ms. Jing's family of three found a beautiful place near Tongshan Road, where there was a large lawn, "set up a tent, lay a mat, and lie down all the time." Ms. Jing said that there is also a large lotus pond nearby, and the child likes to play in the water, so she also follows behind and watches.
"Walking along the river, I saw a lot of pink things on the grass, and from a distance I thought it was a flower, but I got close enough to almost throw up, and one by one I was crowded together, densely packed, very much like insect eggs." After walking around, the lady found that many aquatic plants on the bank of the river had this pink object, "I thought there was some insect infestation, so I asked my child to stay away and didn't go too far to my heart." ”
Then, to Ms. Jing's great delight, the child's father found a "field snail" by the river. "I like to eat field snails, at that time I thought that this kind of 'field snails' was much bigger than what we usually eat, thinking that if we looked for it again, a dozen of them could also take home and eat a meal." Ms. Jing and her family found a total of 21 "field snails" by the river to take home.
Break out in a cold sweat
Search online for cases of food deaths
Because she wanted to make the "field snails" spit mud, Ms. Jing raised these snails with water overnight. "When I washed it the next day, my mother-in-law said that what we brought back might not be a snail, and the tail was retracted, not as long and pointed as the tail of the snail." Ms. Jing said that in order to be on the safe side, she searched the Internet to find out what kind of snail it was and whether it could be eaten, and she was shocked into a cold sweat.
"The Internet says that it is called Fushou snail, you can't eat it, and the pink things on those grasses are the eggs of Fushou snails." Ms. Jing told reporters that she saw on the Internet that there were many cases of eating Fushou snails and even dying in the hospital, and she was afraid when she thought about it. "The Internet says that when you see this pink egg, you must mash it on the spot and kill it, otherwise the Fushou snail will multiply more and more, which is harmful to the ecology." After the lady regretted it, she did not take measures to destroy the eggs of fushou snails.
"I have never seen this kind of thing before, and if other citizens, like me, don't know that this is Fushou snail, it will be too dangerous to take home and eat it as an ordinary field snail." I would like to remind other citizens not to eat things in the wild. ”
Reporters visit
Pink egg masses and adults were found on site
On the afternoon of the 4th, the reporter found the waters reflected by the lady. This place is located in the northeast corner of the intersection of Tongshan Road and Hanjin Road in Zaolin Bay. The reporter entered a small road on the north side of Tongshan Road and continued north, through the lawn and greenery, to the river. Because it was already more than 6 o'clock in the evening and the light was dim, the reporter looked for it through the flashlight lighting of the mobile phone, and saw a pink object on a branch that fell into the water, and then found traces of pink in many aquatic grasses. Looking closer, it was found that each pink egg mass was made up of dozens of neatly arranged eggs, which were small, each less than two millimeters in diameter. Next to a pink egg, the reporter found something that resembled a "field snail". This snail is relatively large, the size of most of an adult's palm, even the area of the snail cover is almost twice the size of a dollar coin, this snail shell is darker in color, there are algae growing on it, and the tail is relatively flat.
The reporter saw a villager nearby and asked him if he knew the name of the snail, and the villager told the reporter that he did not know the specific name, but he saw the ducks raised at home eating this snail. "When it was hot before, there were more ducks by the river, and the free-range ducks ate happily, but recently it seems to be a little less." The villagers said.
【Experts】
This snail should be the Fushou snail
Yesterday morning, the reporter contacted Miao Shuyan, a professor of aquaculture at the College of Animal Science and Technology of Yangzhou University. After seeing the photos sent by the reporter, Teacher Miao said that from the eggs and adult pictures, this snail should be a Fushou snail.
It is now a worldwide invasive alien creature
Teacher Miao introduced that Fushou snail, also known as apple snail, belongs to the bottle snail family. Its origin is the tropical and subtropical regions of Central America and is now part of the world's invasive alien species. In 1981, China introduced fushou snail as an edible economic animal to Zhongshan City, Guangdong Province, and began breeding, and in the breeding boom that arose in the 1980s, it was quickly introduced to Guangxi, Fujian, Sichuan and other places, and even reached Gansu and Liaoning, and then due to poor food taste and marketization failure, farmers have abandoned it. However, due to its strong adaptability, high fertility and fast growth rate, natural populations were quickly established in many provinces and cities in southern China, and caused huge economic losses.
It's not completely unpalatable, but it must be cooked thoroughly
For the consumption of Fushou snail can cause physical discomfort and even endanger life, Teacher Miao explained, because Fushou snail is an intermediate host for the curling thorn mouth fluke and the Guangzhou tube roundworm, these parasites are very harmful to human health. "Fushou snail is not completely unpalatable, it must be cooked and cooked thoroughly when eating to prevent infection with parasites." But the problem is that the meat of Fushou snail will become hard when it is cooked, in order to pursue deliciousness, some chefs may only cook for three or five minutes before coming out of the pot, it is difficult to ensure that Fushou snail is fully cooked, so it is still necessary to be careful when eating. ”

Reflecting that Yangzhou has Fushou snail, it is the first time
The reporter learned from the Municipal Agriculture and Rural Bureau that it was the first time that the situation of fushou snails received in the water was reported. Yesterday afternoon, the staff of the Yizheng Aquatic Products Station and the Yizheng Agricultural Comprehensive Administrative Law Enforcement Brigade went to the scene to inspect it. "We did find pink egg mass at the scene, which is the egg of Fushou snail. However, we asked nearby farmers to help salvage it, and we did not find an adult Fushou snail. The staff of the Yizheng Agricultural Comprehensive Administrative Law Enforcement Brigade told reporters that this is also the first time they have found Fushou snails in the waters under their jurisdiction, which they have never seen before.
As for how to deal with this invasive species, the staff said that they learned that Fushou snails cannot survive winter in Yangzhou, "below 6 degrees Celsius, Fushou snails are difficult to survive." In addition, because we have never encountered it, we have to discuss how to deal with it. The staff told reporters that they had begun to ask their counterparts in the south for advice on how to manage Fushouluo. Journalist Fei Jiajia
