Is it harmful to the body to eat Fushou snails, the harm of Fushou snails

There is a little bit, Fushou snail.

It can be eaten, but it is not delicious, its meat is very chewy, and the risk of eating it is that if you can't cook it, there are a lot of small insects in it, and the small bacteria can't kill it will be very harmful to your health. Even if you cook it, it has a little bit of toxins in it, and there are a lot of them in the field, but because people often spray pesticides, there will definitely be some toxins in it. If it's artificially raised, there's nothing wrong with it, just eat it and cook it.

Fushou snails can be eaten, but they must be cooked.

Due to the outbreak of many food incidents of Angiostrongyloides cantonensis in recent years, many people think that Fushou snails cannot be eaten.

However, Fushou snails should not pay for Angiostrongylus cantonensis infection, and the real cause of this food safety crisis is actually the blind pursuit of taste and disregard for safe cooking methods. Studies on Angiostrongyloides cantonensis have shown that the probability of inactivation of Angiostrongylus cantonensis is 100% in an environment of 80 degrees Celsius, that is, as long as it can be cooked, Angiostrongyloides parasitic in Fushou snails will not pose any threat to the human body at all.

In addition, the snail is by no means the only aquatic organism that carries Angiostrongylus cantonensis, in the whole life of the parasite, it will also parasitize more than 50 kinds of freshwater aquatic organisms such as shrimp, crabs, fish, frogs, etc., and even the Chinese round snail can also be used as a host, that is, if you do not use the correct cooking method to completely inactivate, even if you do not eat the snail, you will still face the risk of infection with Angiostrongylus cantonensis.

We can kill the liver flukes and lung flukes in freshwater fish, shrimp, crabs and shellfish through sufficient heating, and we can also eliminate the anisakis nematodes and tuna worms in marine fish through high or low temperatures.

It's just that we need to keep in mind that we must not rashly use raw food, semi-raw and other ways to eat aquatic products that are unknown and have not undergone any professional treatment, after all, the health of the body is far more important than the enjoyment of the tip of the tongue.

The hazards of Fushou snails are as follows:

1. Cause grain yield reduction: During the rice growth period, Fushou snails will eat rice seedlings and seedlings, resulting in fewer seedlings and fewer effective ears, thereby affecting grain production. According to the relevant statistics of the Agricultural Resources Protection and Utilization Department of the Hunan Provincial Department of Agriculture and Rural Affairs, in recent years, some areas of Hunan have suffered from a shortage of seedlings due to the influence of Fushou snails, and the seedling shortage rate has reached more than 20%, which has affected the rice yield, with an average yield reduction of 5% to 10% per mu, and a particularly serious reduction of 30% to 50% in the rice field.

2. Destroy the growth of vegetables and aquatic plants: Fushou snails eat miscellaneous, like to gnaw plant leaves, etc., aquatic crops such as lotus root in some areas are affected by Fushou snail gnawing, stems and leaves are yellow and wilted, and the yield reduction rate is more than 50%.

Prevention and control of Fushou snails

Before spring ploughing, farmers clean the ditches at the edge of the paddy fields, remove silt and weeds, and take them away from the paddy fields to concentrate on exposure to the sun or dig pits for deep burial. This can kill the overwintering snails to reduce the amount of snails after winter. During the peak spring spawning period from mid-to-late May to early to mid-June, egg masses are removed from the fields and ditches and crushed by the paddy fields in combination with field management.

Secondly, when the number is small, measures such as manual interception, booby-trapping, snail picking, and egg picking are strengthened, supplemented by rice field duck raising, pecking snails and egg masses. In the heavier areas, nylon nets or barbed wire (ranging from the size of rapeseed to the size of beans) are installed at the inlets of the main irrigation canals in the rice area, and fixed with wooden frames or wire frames to make them exceed the water surface by 20 cm to prevent the snails from entering the field with the water.

Fushou snails can be eaten, but it is not recommended to eat them, because the characteristics of Fushou snails lead to incomplete heating and are prone to parasites.

The shell of the snail is hard and thick, and the snail mouth has a hard keratin lid, so it is difficult for the soup to enter the snail meat; The spiral structure in the snail is like a labyrinth, which is not conducive to the conduction of heat; The size of the snail is also relatively large, and it is not easy to burn through. Therefore, it is not that the snail cannot be eaten, but that it should be burned for a while.

However, because the meat of the snail is relatively old, if it is cooked for too long, it may be difficult to chew, which also causes restaurants to prefer to burn it for a while. And some restaurants will ignore the separation of raw and cooked. In the process of handling ingredients, if it is not possible to separate raw and cooked food, shared knives, cutting boards, containers, etc., may allow parasites to contaminate cold dishes or cooked food.

The snail is an invasive species

Although it is unfair to rely on the snail for parasitic diseases, it is really not a good thing. Around the 80s of the last century, people introduced snails from South America, initially as an aquaculture product, and at the same time as a feed for other aquatic products.

Unexpectedly, its fecundity is too strong, and it lacks natural enemies, so it floods and eats the rhizomes of rice in the rice fields, resulting in reduced yields. It is also very damaging to the ecology, because some native snails cannot compete with it, and it has become an out-and-out invasive species.

There are also some "caring people" who do not understand the ecological environment at all, and regard the Fushou snail as a released animal, and spread it to the north and south of the motherland, and even the West Lake in Hangzhou and Erhai Lake in Dali are occupied by it, which is actually a very irresponsible behavior.

Because the snail is large, the shell is hard and thick, the screw lid is hard, it is difficult to cook thoroughly, and the spiral structure in the snail is not conducive to heat conduction, and it is difficult to heat it thoroughly, resulting in a large number of parasite residues, which is very harmful to the human body when eaten.

Why can't you eat snails?

Once infected in the human body, it can cause symptoms such as headache, fever, neck stiffness, etc., and in severe cases, it can cause dementia and even life-threatening.

A professor from South China Agricultural University said that each Fushou snail contains as many as 3,000 to 6,000 larvae of Guangzhou Tubular Stronglinea, and it is recommended not to eat Fushou snails.

Fushou snails are mostly distributed in the fields in the south, and gradually move north in recent years, it should be noted that Fushou snails are not suitable for picking up and feeding directly to chickens, parasites may be transmitted to the human body through poultry, and it is best to mature or crush before feeding.

The harm of the survival of the Fushou snail: strong reproductive ability, floodingDisaster.

Fushou snails are gradually showing signs of overflow. In July 2020, the Yunnan fishery department issued a notice to carry out an operation to remove Fushou snails in the waters of Erhai Lake, and in order to encourage people to actively participate, a special incentive measure was explained: subsidies for captured Fushou snail eggs.

The first large-scale appearance of the Fushou snail that invaded Yunnan was in Dianchi Lake, and then expanded to the surrounding waters, and the Erhai Lake belonged to the "latecomer prevailed", the number was far ahead, and now the wetlands, paddy fields, and lakesides of the Erhai River Basin have the figure of the Fushou snail activity. The eggs of the snail are small pink granules, and dozens of them are densely packed into a cluster, attached to the roots, stems and leaves of the plant. The vitality of Fushou snail eggs is strengthened, and after collection, they are first exposed to the sun to remove the moisture inside, and then burned and submerged, so as to completely cut off the possibility of its "resurgence".

The reason for the fear of the snail stems from its huge fecundity and destructive power. For this reason, as early as 2003, the snail was listed as one of the 16 most harmful alien species that invaded China. March of each year is the first time for snail spawning, the female snail generally chooses to lay eggs at night, spawns several times a year, the amount of eggs is 3-50,000, the egg mass hatching time only needs 8-16 days, and there is almost no natural enemy swallowing snail eggs in the process, so every time the snail goes to an unfamiliar waters, it can grow explosively in a very short time.
