Does Beef Give You Worms if Its
Man Gets xx-Pes Tapeworm from Eating Raw Meat
A human being in China who enjoyed eating raw beef became infected with a parasite — a 20-human foot-long tapeworm —that came from including this food in his diet, a new case report reveals.
The parasite had attached to the 38-year-one-time human being'due south minor intestine and had probable been within him for at least two years before doctors diagnosed the infection equally beef tapeworm of the species Taenia saginata, according to the case report, published online today (Jan. 20) in The New England Periodical of Medicine.
Tapeworm infections are quite rare in Central China, where this case took identify, said Jian Li, of the department of infectious diseases at Renmin Infirmary in Shiyan, China, who diagnosed the man and co-authored the case study.
Although the tapeworm infection charge per unit is quite high in the northwest and southwest districts of People's republic of china, this was the first case of tapeworm seen in this part of China in 30 years, Li said.
Tapeworms are common globally, and Ethiopia, a country where people similar to eat raw meat, has one of the highest rates of infection from beef tapeworm, said Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, Texas, who was not involved in the case.
Only beefiness tapeworms are rare in the United States, Hotez said.
According to the case report, the man went to see his medico in the spring of 2015 considering he was having tummy pain, airsickness, had lost his ambition, felt weak and was losing weight, Li told Live Science. The symptoms had begun just three days earlier, only the man had already lost near 5 to ten kilograms (eleven to 22 lbs.), he said. [The x Most Diabolical and Icky Parasites]
When the man came to the physician'south part, he brought a fragment of the parasite with him that he plant in his stool, Li said. He also told his dr. that he liked to eat raw beef.
From these two pieces of information — the parasite fragment in his stool, which was later examined under a microscope, and his consumption of raw beefiness — the doctors deduced that the man was infected with a beefiness tapeworm, Li said.
Over the past 2 years, the human's medical history too showed that he had been seen by several different doctors and given treatment for stomachaches, pain in his abdomen and anemia, which is a low level of healthy red blood cells.
Tapeworms tin live for years in a person'southward intestines and cause no symptoms, or only balmy ones, such every bit fullness or nausea afterwards eating, Hotez told Live Science.
But it takes a long time for tapeworms to grow as long as this one did, Hotez explained, calculation that other types of invertebrates, an fauna group that includes worms, flies, snails and mosquitoes, tend to not live as long as tapeworms exercise.
No more rare beef
Cattle can become infected with T. saginata when they are out to pasture and feed on the eggs of the parasite, which were passed in human feces, especially in areas of poor sanitation, co-ordinate to the Centers for Disease Control and Prevention (CDC). Those tapeworm eggs can hatch inside the moo-cow, penetrate the intestinal wall and and then broadcast to the beast's muscles.
People tin can go infected with the parasite past eating raw or undercooked beef from a contaminated cow. The tapeworm eggs and larvae tin can migrate to the small intestine, attach to the intestinal wall and mature into an developed tapeworm, the CDC says.
An adult tapeworm tin can produce eggs and tapeworm segments that are shed from the body in feces, according to the CDC.
Tapeworms from a related species, known every bit Taenia solium, tin can be acquired from eating raw or undercooked pork. Merely beef tapeworms tend to grow larger in size (up to 33 anxiety) and produce more eggs than pork tapeworms, co-ordinate to the CDC.
If the larvae of a pork tapeworm have migrated out of the intestines and formed cysts in other tissues, such as the brain, they may cause neurological symptoms, including seizures. Pork tapeworms are a major crusade of hundreds of thousands of cases of epilepsy worldwide, Hotez said. [Top vii Germs in Food That Make Y'all Ill]
Both beefiness and pork tapeworm are considered "neglected tropical diseases," a category of infectious diseases that have never gotten much attending until recently, Hotez said.
In the case report, the human'south doctors explain that they treated their patient with an oral prescription medication that caused him to pass the long tapeworm out of his body two.5 hours later.
Three months after expelling the tapeworm, the man felt better. His appetite and weight returned to normal.
Just he likely will never swallow raw or rare beefiness once more, Li suspects. Being infected with a parasite for at to the lowest degree two years was a very unforgettable experience for the man, he explained.
"It was physically, emotionally and financially exhausting for him," Li said.
