Myth: Some people believe that marine fish can be made sashimi, and freshwater fish can also be eaten raw with sashimi, so that the taste is delicious and nutritious.
Truth: Freshwater fish may have a variety of parasites on them, and if eaten, they may affect their health.
In freshwater aquatic products, there are more parasites that can infect people, but because Chinese food is often mainly cooked, it is not very common. But in recent years, because some merchants have begun to develop the birth fresh eating method, this type of case has an increasing trend, here can only pick a few of them to briefly introduce, you want to see the future also plan to eat freshwater sashimi what that counts me lose...
First of all, let's talk about liver flukes (i.e., Chinese mycodystis, see figure below), which is a common freshwater fish parasite, and its larvae can parasitize common fish such as carp, bluefish, grass carp and freshwater shrimp. If infected, severe cases can lead to cirrhosis, ascites, and even death.

There is also a parasite called jaw-mouth nematode, the larvae can infect eels, loach, blackfish and other fish, if people accidentally eat the stomach, there will be fever, stomach pain, vomiting and other symptoms, not only that, the larva will also move slowly in the shallow layer of human skin. In addition to the rash, the patient will also find a lump on the skin, and after a while the lump will run elsewhere... If you think about it a little, you will know that this taste will never be good, and what is more fatal is that the internal organs and even the brain, eyeballs, etc., the jaw-mouth nematode can also burrow in and cause serious consequences.
Fortunately, jaw-mouth nematode disease is rare and easy to prevent, and in 16 patients in a study in 2017, most of them have eaten raw eels and loach, and other patients often eat fried eels and loach, which does not rule out the situation of not cooking. So as long as we keep our mouths shut a little, don't try the so-called "ice eel slices" and other raw dishes, and make sure that the fish is cooked and then eaten, it is basically out of touch with this disease.
There are many parasites on freshwater fish, so what can river crabs do?
Lung flukes, larvae can infect crabs, crayfish, freshwater snails, if not cooked, people eat it may be infected, insects in the human body wandering, may lead to fever, loss of appetite, abdominal pain, diarrhea, allergies and other issues, such as invasion of the liver, may also cause cirrhosis. If it is parasitic in the brain, it may damage the person's nerves, lead to epilepsy, paralysis, vision loss and other problems.
Tubeworm can infect freshwater snails and fish, and if infected, it may lead to encephalitis or meningitis. African large snails, which are common hosts of Guangzhou tube ringworm, should not be picked up and eaten at home and do not touch, because contact is also low because the skin and mucous membranes are infected by larvae.
Although the above mentioned a number of such and such parasites, but there is no need to choke on food, because as long as you steam, stew and fry, the parasites are completely killed, there is nothing to worry about, the so-called pipe you have a good time before you die, cooked are protein... It should be noted that if the sashimi or shabu-shabu is not heated enough, it may not be able to kill the parasite.
Many of the so-called "insecticidal" methods that have been circulating for a long time have a worrying effect, such as sprinkling salt, soaking vinegar, soaking soy sauce, dipping mustard, white wine, etc., which are very unreliable.
You know, all the parasites that can infect people through the digestive tract have many means of survival, otherwise how can they escape from the harsh environment full of stomach acid and digestive enzymes and lack of oxygen, and plague our bodies? The seasonings mentioned earlier, the time of contact with the parasite is so short, the concentration can not be guaranteed, can not play an effective killing effect.
Don't keep your mouth shut, travel or explore the shop, don't try raw game for curiosity. If you do not resist the temptation and become unwell after eating raw food, tell the doctor what you ate at the time of treatment so that the doctor can make a better judgment.
