Recently, some people found that they were not cooked when eating beef frogs in the restaurant. They looked closely at the white wire-shaped objects found in the meat of the beef frogs. They were suspected parasites. This surprised them. They were reminded by the hospital to come to the China Center for Disease Control and Prevention (CRC). Disease prevention and control check. This case once again raised people's concerns about parasites. In the end how to eat to prevent parasites, food-borne parasites how far away from us?
Zhou Xiaonong, director of the Institute of Parasitic Diseases Prevention and Control at the Chinese Center for Disease Control and Prevention, said that the incidence of parasitic diseases has been in a downward trend. In recent years, the proportion of food-borne parasitic diseases has increased. More than ever before, choose more and bolder diets. However, in order to prevent parasitic infections, raw foods or semi-aquaculture products, vegetables, and cooked foods should be promoted.
There may also be parasites in vegetables
Bullfrogs are delicious and many people are concerned. Is it safe to eat bullfrogs? Zhou Xiaonong said that frogs do have a higher probability of being infected with parasites, but since most bullfrogs are farmed, the probability of infection is likely to be relatively low. If the bullfrog is wild, there may be Mansard's schizophrenia infection. If someone eats raw or half-lives wild bullfrogs, it may cause Mansard's sparganosis. This parasite larva, which is known as the Spirometra mantis, can enter the brain through blood circulation and cause damage to the brain.
Sashimi is another ingredient that has been referred to as parasites. There are two kinds of sashimi, and it is generally believed that the parasites of freshwater fish are more harmful. Among them, the most representative and the most harmful species is the schistosomiasis (commonly known as liver flukes). People eat sashimi after infection. When the body is parasitized in the biliary tract and the infection is large, it can reach several hundred and block the biliary tract. It is generally believed that deep-sea fish are relatively safe, but marine fish such as salmon, red clams, and tuna may also infect broad-spotted crustaceans, and become infected after eating their food, resulting in broad-spotted crustacean disease.
Not only that, in fact, all kinds of foods may have the risk of parasites. For example, sashimi may have liver fluke; pork can parasitize tapeworm cysticercosis, larvae of Trichinella spiralis; beef can parasitize cysticercus of tapeworm; in regions of western echinococcosis, sheep may be infected with echinococcosis Larvae of locusts... Raw foods Eating raw meat or eating vegetables or water contaminated by these parasites may cause diseases. For example, contaminated vegetables may have schistosomiasis, contaminated water sources may contain cryptosporidium, giardia, and so on.
Parasites can cause cancer and even death
The harm of parasites to the human body has many aspects, and the pathogenesis of various parasites is different. For example, larvae migrate in the human body, can cause mechanical damage to organs, such as paragonal mass and lung injury caused by Paragonimus (commonly known as paragonimiasis); or cause allergic reactions, such as urticaria and skin in patients with tsutsugamushi disease. Itching, angioneurotic edema, and conjunctivitis symptoms.
The presence of parasites can also cause complications that invade the central nervous system. For example, angiostrongylus cantonensis infection larvae invade the human nervous system caused by epilepsy and other meningoencephalitis symptoms; cerebral paragonimiasis enters the brain, causing increased intracranial pressure, and stimulate the cerebral cortex, causing brain tissue destruction, meningoencephalitis, Subarachnoid hemorrhage and epilepsy and other symptoms and signs; fissochroocerebral encephalopathy, clinical manifestations resembles brain tumors, often have a history of paroxysmal headache, severe coma or with jet vomiting, blurred vision, intermittent spat, limb numbness, convulsions , or even paralysis, etc., are easily misdiagnosed...
Parasites can also be crippled, carcinogenic, and even dead. Such as the filariasis infection can cause rubber leg in the late; repeated infections of Clonorchis sinensis can cause gallbladder cancer; schistosomiasis can cause liver cancer or intestinal tumors in the late; Trichinella, Plasmodium falciparum infection can cause death if not treated in time.
In addition, some parasites may also affect development. For example, tongue infection may lead to stagnation in children, schistosomiasis may cause dwarfism in children and stop development, and have no ability to reproduce.
Parasitic treatment is cheap
Many people may have such questions. Is there any way to know if I have eaten parasites? What kind of symptoms would it be if there were parasites? Zhou Xiaonong said that indeed many patients do not know the cause of the disease after having acquired parasites, they do not think about parasites, and even some hospitals do not have experience, making these diseases rare diseases. At present, the National Institute of Parasitic Disease Control and Prevention of the National Center for Disease Control and Prevention has networked with all of the city's top three hospitals. Once the cases are found, they can be quickly and accurately treated. The network with the hospital is also being covered.
Parasitic disease is usually characterized by fever, diarrhea, and increased eosinophils. If it is because of fever, diarrhea, and the examination report has eosinophilia, you should consider whether you have a parasite. Surprisingly, the treatment of parasitic diseases is often very cheap, because the therapeutic drugs are generally only a few yuan to tens of dollars. "Some patients had unknown causes at first, and the treatment cost more than 30,000 yuan. Later they were diagnosed with parasitism and they were cured after spending tens of yuan."
Therefore, the key to treating parasites is rapid diagnosis. The sooner the better, the timely treatment of parasites is not only less costly, but also completely curable. Zhou Xiaonong introduced that the current level of parasite treatment in Shanghai ranks first in the country, and with the improvement of sanitary conditions, the overall incidence of parasitic diseases showed a downward trend. However, it is worth noting that the proportion of food-borne parasitic diseases is on the increase due to the improvement of people's living standards and the variety of food they eat. Therefore, in the pursuit of good food, we must also strive to eat "healthy", be sure to pay attention not to "insects from the mouth."

Marine fish kills parasites at -20°C for more than one week
Although the parasites in meat are terrible, taking the right approach can still prevent and kill them. First of all, it is necessary to strengthen inspection and quarantine of animal meat so that “problem meat†will not be sold to the market. For consumers, it is recommended to cook meat and not eat raw food.
Usually the parasites can be killed by high temperature cooking. Water boiling at 100°C can kill the parasites in the water. When the center temperature of the meat reaches above 85°C for a long time, the parasites in the meat can be killed. insect. At present, there are many products such as raw fish fillets and raw beef salads on the market. To prevent parasitic infections, raw foods or half-aquaculture products, vegetables, and cooked foods should be encouraged.
For consumers who really like sashimi, the safety of marine fish is higher than that of freshwater fish. If it is considered that cooking will affect the taste of sashimi, some fish may be frozen at minus 20 degrees for more than 7 days according to the standard. To achieve the effect of killing parasite larvae.
