However, users of dishes Mixed salad with pork, beef, buffalo If not processed carefully, there is a risk of disease tapeworms. According to the Ministry of Health, tapeworm disease is distributed in many countries with difficult economic conditions and poor environmental sanitation in Africa, Latin America, Southeast Asia… including Vietnam.
Taeniasis is a parasitic disease transmitted from animals to humans caused by the practice of eating undercooked pork and beef contaminated with tapeworm larvae.
Regarding the causative agent, tapeworm disease is caused by adult tapeworm species including pork tapeworm (Taenia solium), beef tapeworm (Taenia saginata), and Asian tapeworm (Taenia asiatica) parasitic in the intestine. The source of the disease is from pigs, buffaloes and cows carrying tapeworm larvae.
People of all ages and both sexes can get tapeworms. Specific antibodies may appear 3-4 weeks following infection and are short-lived. There are two main stages of infection with tapeworms.
Adult hermaphroditic tapeworms live in the intestines of humans. Burning fluke, which crawls out on its own or in feces, is decomposed to release eggs. This is the diagnostic phase.
Cattle, cows, pigs ingest eggs and burn tapeworms that are dispersed in the environment or eat human feces containing tapeworm eggs. After entering the stomach and intestines (of buffaloes, cows, pigs), the larvae are hatched and pass through the digestive tract wall into the bloodstream, to the striated muscles that create cocoons there.
People who eat pork, buffalo or cows with live larval cysts, the tapeworm larvae enter the intestines and hatch into an adult tapeworm. This is the infection stage. In the case of people ingesting pork tapeworm eggs, it will develop into larval disease.
When newly hatched, tapeworms only have a head and a neck segment. The fluke grows and develops by budding, producing new segments from the neck and gradually elongating, living in the small intestine. Adult tapeworm length is usually 5 m or less for beef tapeworms (but can also be up to 25 m) and 2 to 7 m for pork tapeworms.
When infected with tapeworm, patients often have atypical symptoms such as: Abdominal pain is a common symptom, dull pain around the navel. Nausea, vomiting. Gastrointestinal disturbances, usually constipation or diarrhea. Occasionally see tapeworms crawling out the anus or in the feces.
