Recently a photo of a long beef tapeworm hit the Internet, according to reports, the patient's surname Chen, 45 years old, Nanning Binyang people, usually like to eat sashimi, raw beef, etc., although to meet the stomach and mouth,, but also suffered from liver fluke disease and tapeworm disease, in the hospital to remove insects for 5 days, on the morning of the 21st, the hospital laboratory laboratory from the patient's body after the discharge of the specimen, found 500 cm long cattle tapeworm.
Many people may not have heard of beef tapeworms, but what is this beef tapeworm? Taenia beef, commonly known as bovine ribbon worm, belongs to the phylum of flattened animals, tapeworms, suborder polysocaria, round leaf order, band family. When cattle swallow eggs while grazing, the eggs hatch into six-junky worms in their duodenum, which cross the intestinal wall with blood flow or lymphatic vessels, carry them to the muscles, and develop into cysticercosis after two months. If beef that is not yet fully cooked is eaten and the cysticercosis in the meat is not completely killed, then the eater will be infected. After the beef tapeworm enters the human body, it can become an adult worm in about three months, and it can grow and easily explode two Yao Ming in length.
Don't think that if you don't eat beef, you won't be caught, in fact, beef tapeworms can not only be found in cattle and buffalo, but also distribute the muscles of sheep, deer and other animals, so be careful when eating the above animals. From the time of swallowing bovis to the appearance of insects in the feces, it takes about 3 months. The severity of symptoms is related to the number of parasites in the body, ranging from asymptomatic to severe cases where symptoms are obvious or even death from complications.
White nodules are found in the stool as the most common symptom, and patients often go to the hospital for treatment. Abdominal pain is most common among gastrointestinal symptoms. Abdominal pain may be in the upper abdomen, peri-umbilical cord, or in no fixed position, and may be dull, faint, tingling, biting, or burning, and a small number of patients may have colic. In addition, there may be nausea, vomiting, diarrhea and other symptoms. If you eat beef raw, you should consider whether you are infected with beef tapeworm once this happens.
No one wants to grow a bug taller than Yao Ming in their stomach, and the effective prevention of beef tapeworm infection should do the following:
(1) Pay attention to personal hygiene, improve diet and hygiene habits, meat must be cooked thoroughly. It is best not to buy untested beef, wash and blanch the cutting board and knife with boiling water after cutting the beef, and do not eat raw or undercooked beef.
(2) Strengthen the inspection and processing of meat. If there are no live cysticercles in the meat eaten, it is impossible for a person to be infected with taenia oxensis. Therefore, meat inspection and processing should be strengthened.
(3) Strengthen the work of slaughterhouses, and strictly prohibit the sale of cattle with tapeworm larvae. Strengthen the management of cattle breeding, in order to prevent cattle infection, the toilet should be separated from the barn to prevent cattle from eating people's stool.
(4) If you suspect eating raw meat, once the above related symptoms appear, you should go to the hospital for diagnosis and treatment in time.
In fact, beef tapeworm also has a "twin brother" - pork tapeworm, smart you must know that pork can not be eaten raw. Pork tapeworms are called inch white worms or white worms in ancient medical texts. As early as 217 AD, there was a record of white worms in the "Outline of the Golden Plateau", and in 610 AD, Chao Yuanfang described the insect body form as "one inch long and white in color and small flat shape" in the "Theory of the Origin of Diseases", and pointed out that it was infected by eating meat.
The shape and length of the pork tapeworm are somewhat similar to the beef tapeworm, but its more terrifying point is that it can enter the intestinal wall through the digestive tract and then enter the blood circulation through the mesenteric veins, sending the eggs to the brain, causing a series of symptoms. Therefore, taeniasis in pork is also called "cerebral cysticercosis". I believe that seeing here, in order to avoid the appearance of tapeworm jun in the stomach, you who originally liked to eat raw steak and tender meat slices should decisively "powder the way".
