Today, a Weibo post of the museum magazine was forwarded, and someone asked whether the water chestnut really could not be eaten raw, otherwise it would be infected with parasites.

After forwarding, I found that many parents in the comment area left messages saying that they had eaten raw watercress from childhood to adulthood. This risk is really not small, so I think it is necessary to briefly talk about it: what kind of parasite is ginger slice insect? What happens if I am infected with ginger slice worms? Which aquatic plants are at high risk?
Ginger flakes, full name Bucholas ginger flakes flukes, is a medium, large, flattened parasite. Humans are one of the ultimate hosts of gingeria. The life cycle of ginger slices is as follows:
Humans are infected with ginger flakes, and the unfertilized eggs in the intestine are excreted with feces
The eggs are fertilized and hatched in a suitable freshwater environment (e.g. at temperatures of 27 to 32°C).
Releases caterpillars and parasitizes to develop in environmentally appropriate freshwater snails (intermediate host)
Experiencing cymbals (terrestris(tailed larvae
Tailed larvae escape from freshwater snails and adsorb on aquatic plants to form cysticercos (second intermediate host)
Mammalian hosts (humans or pigs) eat contaminated aquatic plants by mistake
Cysticers are decanted in the duodenum and attach to the intestinal wall
In the intestine for about 3 months, it develops into an adult worm

After infection with ginger flakes, symptoms can be mild or severe or even asymptomatic, mainly related to the severity of infection and the health status of infected individuals.
Non-severe symptoms are mainly concentrated in the digestive tract, such as poor appetite, abdominal pain, diarrhea, nausea, vomiting; diarrhea and constipation occur alternately; children may have neurological symptoms, such as affecting sleep, convulsions, etc.
Patients with severe illness may have problems such as mental malaise, emaciation, and puffiness; children with long-term repeated and serious infections may even have problems such as backward development and mental decline. Long-term diarrhea and severe malnutrition can even lead to secondary infections of the intestines and lungs, as well as death.
Of course, according to the available epidemiological statistics, most infected people are mild or asymptomatic. If the child has the habit of eating aquatic plants raw, and at the same time has chronic abdominal pain, diarrhea, puffiness and other manifestations, it is necessary to be vigilant against the possibility of infection with ginger flakes. Doctors can determine whether and how much infection is possible by testing eggs in the stool, such as:
Less than 2,000 fecal eggs per gram are mildly infected; 2000 ~ 10000, moderate infection; More than 10,000 are severe infections.
Aquatic plants that have been confirmed to be at risk of infection with ginger flakes include diamond horns, water chestnuts, white leaves, and lotus roots. Among them, the diamond angle includes different varieties such as water red diamond, large diamond, large thorn diamond, South Lake diamond, curved angle diamond, octagonal diamond and so on.
The ginger cysticers attached to various aquatic plants can be more or less, according to relevant reports, more than 500 cysticers have been found on 1 diamond. Therefore, eating aquatic plants raw is at risk of contracting ginger flakes, and as for the severity of infection, it is "depending on luck".
Human infection with ginger flakes is mainly associated with eating high-risk aquatic plants raw, and the patients are mostly children and adolescents. According to the available statistics, the high incidence of ginger flake infection season is closely related to the peak season of Lingjiao listing, such as September to October in Zhejiang and July in Guangdong.
Therefore, if you want to avoid ginger slice insect infection, you must carefully wash the ingredients and cook them thoroughly. In fact, this principle is the same as freshwater snails and freshwater fish to be thoroughly cooked and eaten.
