Pork tapeworm is also known as Porzoa solium, or hook tapeworm, flat animal phylum, tapeworm class, banded family. The body is white and banded, 2-4 m in total, 7-8 mm wide. The body is divided into three parts: the cephalic segment, the neck and the proglottid.
Anaerobic organisms. However, its larvae and larvae grow in an aerobic environment).

TapewormsBelongs to intestinal parasites, belongsPhylum Platyzoaof the class Tapeworms.
Tapeworms are giant intestinal parasites, and the average adult can reach up to 72 feet in length. There are more than 30 species of tapeworms that parasitize the human body. Adults parasitize vertebrates, and larvae mainly parasitize invertebrates.
or with vertebrates as intermediate hosts. It belongs to the class Taenia of the phylum Flattenoids. The dorsal and ventral bodies of the adults of this class are flattened, symmetrical, mostly segmented, long as a ribbon, and without a mouth.
and the digestive tract, lacking body cavities, all of which, with very few exceptions, are hermaphroditic.
Tapeworm infection route
Most of the adult worms live in the digestive tract of vertebrates, and they need 1 to 2 intermediate hosts in their life history, and the period of development in the middle host is called the middle tapestry stage. Tapeworm proglottids and eggs are excreted in human feces and contaminate the surrounding environment if pigs or cattle eat the eggs.
After 48 to 72 hours, the eggs of the hexanechovie will emerge from their intestines, pass through the intestinal wall and enter the bloodstream, and travel with the bloodstream to all parts of the body, where they will develop into cysticerci after 60 to 70 days. Cysticerci can survive in pigs for 3 to 5 years. Children eat pork or beef containing cysticerci and under the action of small intestinal fluid, the cysticerci head segment turns out, adsorbs on the intestinal wall, and develops into adult worms after 2 to 3 months.
Children may also eat food contaminated with eggs, which shed their shells in the intestine and hatched into hookworms, which pass through the intestinal wall and follow the bloodstream to all tissues throughout the body to develop into cysticercosis.

Summary. Now there are health prisons for inspection and quarantine, and there is little chance of buying pork with tapeworms. If you accidentally ingest, you should confirm the illness before taking medicine.
The incubation period of taeniasis is about 2 to 3 months, and most patients are infected with monoworms, and it is more common for people to come to the doctor within 3 months. The most common clinical symptom is the discovery of proglottites in the stool, and patients may have mild anal itching. Abdominal pain occurs in about half of cases and is usually not severe.
It is dull in nature and is located in the upper or whole abdomen. Some patients have diarrhea, fatigue, hyperphagia, and weight loss. Diagnosis:
1) The diagnosis can be made if there are white noodles or bands of motile worms in the stool. 2) Stool examination 3) Anal smear examination 4) Pregnancy somite examination. If the diagnosis of taeniasis is confirmed, drugs can be taken:
a) betel nut or betel nut combined with pumpkin seeds**. b) Raimaru. Three A's flat.
The chance of pork having tapeworms is very small and almost negligible.
I'm sorry I don't understand, but can you elaborate on that?

Pork tapeworm is the main human parasitic tapeworm in China, called inch white worm or white worm in ancient medical books, pig cysticerci such as the size of soybeans, white translucent sac, the cyst is filled with transparent cyst fluid, the cyst wall is divided into two layers, the outer is the cortex, the inner is the interstitial layer.
Humans are the definitive host of pork tapeworm and can also be used as its intermediate host; Pigs and wild boars are the main intermediate hosts. Experiments with cysticerci in pigs were used to infect white-handed gibbons and giant baboons. Adult worms live in the upper part of the human small intestine and hold the intestinal wall in place with the cephalic.
The pregnant joints often fall off from the chain body alone or in connection with 5-6 segments, and are discharged with feces, and the pregnant joints that are separated from the insect body still have a certain degree of activity.

Parasite.
Ascaris is generally a parasite in the belly of a pig. Ascaris eggs are often mixed with feces into the soil and raw water, and pigs will eat in the stomach if the pig house is not clean, and roundworms will parasitize.
If people do not wash their hands before eating, drinking raw water or melons and fruits, roundworm eggs will be eaten into the stomach, and in this way, roundworms will grow in people's stomachs.
The parasite that is really likely to appear in pork and is visible to the naked eye is the larval form of the pork tapeworm, the cyst. They are white grains in the shape of rice grains in pork, which is commonly referred to as "rice pork" and "bean pork".
The larvae are eaten in the stomach before they have a chance to hatch into adult worms in the human intestine, and pigs are only their "springboard for infection", and in pork, they do not show long threads. The situation is similar for Trichinella suis.
In fact, before and after slaughtering, the staff will conduct a detailed inspection to determine whether there are various parasites in the pork. Therefore, as long as you buy from regular sources, the chances of encountering these parasites in pork are actually very small.
Pork belly boils
Consumers always pay close attention to parasites when buying pork, but after inspection and quarantine, the risk of parasites in regular products is actually very small.
In fact, when it comes to parasites, the most important thing to be wary of is pork belly boils, which are considered "medicinal food" in some places. In some areas of China, wild boar belly is considered to be a sacred object of "stomach nourishment", and people will specially find wild boar belly to eat, in an attempt to use it to maintain health and cure diseases.
According to folk rumors, some wild boars are covered with "boils" on their stomachs, and the more "boils" they have, the more poisonous snakes the wild boars have eaten before their deaths, and the more "stomach-nourishing" such pork bellies are. In fact, these "boils" are signs of digestive parasites.
In fact, the real parasite "rice pork" will not flow into the regular pork market, so there is no need to panic excessively. The "white strips" in pork sold in the regular market are mostly pig tendons or other tissues on the pig's body, not parasites.
