1 kg of snail eggs can be exchanged for 40 yuan. What harm will Ampullaria canaliculata bring to human body?

According to media reports, a large number of exotic species Pomacea canaliculata appeared in Erhai Lake, Dali, Yunnan, endangering the local ecological environment. According to the report, the staff of Dali Municipal People's Government said that Ampullaria gigas has existed in Erhai Lake for many years, and it will be cleaned up almost every year. On the 4th of this month, Dali municipal government issued the policy of prevention and control of snail epidemic again, and introduced the policy of rewarding 40 yuan with snail eggs 1 kg.

Pomacea canaliculata is a mollusk belonging to the genus Pomacea, and its shell is similar to that of a snail. I like to live in fresh water with fresh water quality and sufficient bait, and live in shallow water near the pool in groups. They are omnivorous snails with a wide range of food habits, and they also like to eat carrion from animals in the water. It is a worldwide alien invasive organism, which has been listed as one of the alien invasive organisms in major dangerous agriculture by the State Environmental Protection Administration of China.

Pomacea canaliculata is introduced from abroad as food, which is easy to parasitize Angiostrongylus cantonensis. Uncooked snail meat can cause human infection with Angiostrongylus cantonensis. Two years ago? Beijing Pomacea Snail Incident? It is because the cold snail meat is mostly polluted by the larvae of Angiostrongylus cantonensis. Well-done snails? Will not cause symptoms. Angiostrongylus is parasitic in freshwater fish, shrimp, snails, crabs, frogs, snakes and other animals. As long as you don't eat this raw or undercooked dish, you won't be infected with Angiostrongylus cantonensis. Snails eat rice and other agricultural plants, which leads to a decrease in yield, which can easily destroy the local wetland ecosystem and agricultural ecosystem. Pomacea canaliculata has a large appetite, can eat rough plants and scrape algae, and its excrement will pollute the water body. Obviously, its loss to rice production greatly exceeds its value as a delicacy. Ampullaria canaliculata is not only a threat to aquatic shellfish and aquatic plants, but also an intermediate host of Echinococcus China and Angiostrongylus cantonensis.

From this point of view, Pomacea canaliculata is very harmful to us, and we need to exchange 1 kg Pomacea canaliculata eggs for 40 yuan.
