    There are parasites in crayfish, which are harmful to the human body:

    If a person eats crayfish raw or half-baked, it is very likely to be infected with this parasite, which can cause paragonimiasis. Lung flukes are mainly parasitic on the human lungs, and can be manifested as cough, chest pain, hemoptysis, and severe cases may cause massive bleeding in the lungs, block the organs, and lead to death. There were three Beijingers who were poisoned by eating crayfish and developed "acute skeletal myolysis", which was almost life-threatening.

    The prevention and control methods are:

    Remove the tendons on the back of the lobster before eating, and cook it thoroughly when cooking, and it is best not to eat the head of the crayfish when eating.

    Crayfish (crickets) and crabs are the second intermediate hosts of lung flukes. Adult lung flukes live on the lungs or other tissues of humans and mammals. The eggs produced by the adult parasitic lungs can be coughed up with sputum through the trachea or discharged with feces in the digestive tract, and the eggs are developed into mature larvae and hatched after about 20 days in the water, and the larvae invade the first intermediate host (freshwater snails such as snails and snails), and reproduce asexually in the snail through the stages of cytolaria, female thunderlarvae, and sub-larvae, and after about 3 months, a large number of cercariae are formed, and mature cercariae escape from the snail to invade the second intermediate host (crab and cricket) or be swallowed by the second intermediate host with the snail, Cercariae form cysts in the muscles or internal organs of the second intermediate host.

    Hazards: When people eat or semi-raw crabs or crickets containing cysts, cysts will then enter the human body, become larvae after being decapsulated in the human intestine, pass through the intestinal wall, migrate in the abdominal cavity, abdominal wall and other tissues and organs, and the larvae finally reach the lungs to develop into mature adult worms, thus causing severe paragonimiasis in humans. Pargonimiasis involves multiple tissues and organs, and its clinical manifestations are variable and complex with the course of the disease.

    Crayfish do have parasites on them, because they are species that live in the wild. In particular, some crayfish living in polluted waters are more likely to have parasites, such as lung flukes, capillary nematodes, echinocephalus, trypanosomes and other parasites. Crayfish like to live in a fertile and dirty sewage environment, and many parasites are parasitic, such as lung flukes, capillary nematodes, echinocephalus, trypanosomes, leeches and other parasites.

    These parasites not only harm crayfish, but people can also be infected with parasitic diseases if they eat undercooked, sterilized and sterilized crayfish.

    Parasites are weak in their ability to live on their own, and generally cannot adapt to changes in the environment, and can only survive on the nutrients and environment provided by the host. The longer the life history, the more adaptable it is to the host. For organisms in the water body, parasites first survive and reproduce in some algae, macroplants or small zooplankton, snails, mussels, etc., and then transfer to the body of shrimp, crab and fish with the change of the food chain, and finally transfer to the human body due to inappropriate eating methods.

    First of all, the crayfish is rinsed with water several times, put a little white vinegar in the crayfish for 10 minutes, scrub it clean with a brush, cut off one-third of the head and take out the shrimp sac, the mouth can not be cut big, cut it big when cleaning and cooking, the shrimp yellow is easy to lose when cleaning and cooking, the shrimp line is pulled out by turning left 45 degrees in the middle of the tail back, and the back is cleaned with a knife and set aside. Raw or half-cooked food can infect the body with the parasite, causing paragonimiasis. These are all known parasites, and crayfish of unknown origin may be infected with more parasites, so they should be cleaned up.

    The crayfish itself is difficult to clean, and most of the crayfish on the market are simply cleaned to remove the sediment on the surface of the crayfish. The head and gills of crayfish are difficult to be cleaned, so the shrimp head has become the dirtiest place for crayfish. The key to preventing parasitic diseases is to cook them thoroughly (it is safer to cook them at 100 degrees for more than 10 minutes), especially not to eat raw or half-cooked crayfish.

    Yes. Eating crayfish regularly may make the body prone to allergies, plus crayfish are high in protein and not easy to digest, which may cause diarrhea. In addition, some crayfish also have toxins in their bodies, which may cause rhabdomyolysis, and parasites can easily cause bacterial infections, which also have a great impact on health.

    If the crayfish is not cooked thoroughly or the water used to wash the crayfish contaminates other food that is directly consumed, such as raw and cooked food, sharing cutting boards, knives and shovels and other kitchen utensils, the eggs of lung flukes may take the opportunity to enter the human body.

    Preventing the disease from entering the mouth is the key to preventing infection with foodborne parasitic diseases. People who have a habit of eating raw food, or who have symptoms related to parasitic diseases, should be tested for intestinal parasite prophylaxis in time.

    Introduction: It is said that no summer is complete without crayfish. In the summer, people always like to use crayfish with skewers and some carbonated drinks, which is simply not too refreshing.

    Although eating crayfish can be very satisfying, if you eat crayfish that is not clean, it can also cause many diseases. So the topic I want to share today is that crayfish have a lot of parasites in their bodies, what are the health effects of eating crayfish?

    1. What are the health effects of eating crayfish?

    The environment in which crayfish live is relatively dirty, and the dirtier the environment, the higher the survival rate of crayfish. And crayfish are omnivores and especially like to eat rotten small animals. Crayfish can parasitize lung flukes in their bodies, and if they are eaten raw or undercooked, it is easy for the human body to be infected with parasites, which can cause lung diseases.

    Mild patients will experience coughing, chest pain, and coughing up blood. In severe cases, epilepsy or hemiplegia can occur, and the impact is very large. And it is difficult to clean up the crayfish in the restaurant outside, if you eat unhygienic crayfish, it will be easy to make the body sick, it will be a bit more than worth the loss.

    2. What are the precautions for eating crayfish?

    If you make crayfish by yourself, then before doing it, you must wash the crayfish repeatedly, and put the crayfish in the water for a few hours, and then constantly change the water and wash it constantly. In the process of cooking crayfish, be sure to cook for 10 minutes, and the crayfish must be completely cooked and cooked thoroughly. In this way, it can achieve the effect of high temperature sterilization, although the crayfish is delicious, but the head of the crayfish contains liver, stomach, gills and other organs.

    And there are a lot of pollutants accumulated, so when eating crayfish, try not to eat the head, only the shrimp tail. If you eat shrimp in a restaurant, try to choose some reliable restaurants with a business license, because reputable medium and large restaurants will have better hygiene conditions than food stalls, and can also ensure health. Crayfish must not be hoarded too much, you must buy as you eat, eat fresh crayfish, the taste will be more delicious.

    Aquatic animals such as crayfish and crabs may contain a variety of parasites, such as raw or undercooked consumption, which can cause parasitic diseases in humans. The experimental results showed that oval and constantly moving parasite eggs could be seen in many places in the sample solution after the ultrasonic cleaning machine was cleaned, and the active eggs disappeared after heating for 10 minutes under the heating condition of more than 50 degrees.

    This situation exists, but by heating, it can effectively kill the parasite eggs, so it needs to be fully heated and cooked before eating.
