Before using food products of pig breeding, it must be subjected to thorough heat treatment due to the risk of the presence of parasites in the pork. There are a number of dangerous worms, protozoa, having a different life cycle. Some of them can infect a person randomly, for others he is the main owner. Inside the human body, worms reach sexual maturity, representing a serious threat to the life and health of people.
Varieties of dangerous parasites pigs
In pork meat can be eggs, larvae of worms, parasitic microorganisms. When such foods are consumed, the larvae of parasites appear inside the human body from cysts. They penetrate through the capillaries into the bloodstream, moving with the bloodstream to all internal organs.
Many of them reach the intestines and other internal organs of puberty. Increasing in size, they poison the body from the inside with the products of their vital activity, create mechanical obstacles in the respiratory tract, the gastrointestinal tract.
Among the most dangerous parasites for humans are the following types of them:
- Toxoplasma, sarkosporidii, which belong to the simplest;
- trichinella, toxocaras belonging to the class of nematodes (roundworms);
- fluke class gnatosomes;
- echinococcus, pork, bovine tapeworm as representatives of tapeworms.
In addition, pork can be infected from the outside through flour beetles, cockroaches. These insects often carry eggs of the dwarf chain, which causes people to hymenolepiasis.
Various helminths, protozoa microorganisms have a pathological effect on human health, often provoking irreversible changes within the human body, which sometimes cause deaths.
Diseases caused by parasites that are inside the pork
For the simplest parasites, pigs are intermediate hosts. Animals eat their eggs along with grass and feed. Inside their bodies, parasites are transformed into forms that infect muscle tissue.
By eating the meat of such animals, a person is at risk of helminthic invasions called toxoplasmosis, sarkosporidiosis. In addition, you can become infected with parasites through cutting boards, knives, dishes.
Roundworm eggs infect meat, pig liver. If a person eats these products, then he has diseases of trichinosis and toxocarosis, which are accompanied by inflammatory processes, severe obsessive pain, general weakness, nausea.
Flukes use pigs as primary and intermediate hosts along with fish, snails and frogs. Once inside the human body, they move under the skin, tissues, causing inflammation, itching, and allergic reactions.
Pig tapeworm enters the body of animals through feed, infected cysts of these parasites. They cause cysticercosis and teniarinhoz in humans. After infection, helminths at different stages of development are parasitized in muscles, lungs, liver, and subcutaneous tissues.
In addition, the eyes, nervous system, and human brain are exposed to the dangers of this worm infestation. These parasitic infections can occur through direct contact with pigs. Most cases of disease are associated with the consumption of meat without sufficient heat treatment.
Features of the life cycle of Trichinella
Among the many parasites, the most dangerous for humans is the helminth Trichinella spiralis. These worms actively multiply, producing the larvae resistant to adverse conditions.
The whole life of this parasite goes inside the same host. After mating in the small intestine, the male dies, and after a while the larvae appear. Having made their way through the mucous membrane, they get inside the bloodstream and are spread to different tissues and internal organs.
Most of the larvae of these parasites penetrate the muscle tissue of the upper shoulder girdle, neck and head. There they grow intensively, stimulating the development of blood vessels around them. After some time in these places seals form.
About three weeks later, the parasite enters the small intestine, after which it begins to destroy the cells around it, arranging the living space. Having settled there, he reaches sexual maturity and multiplies, poisoning the "owner" with the products of his life activity, reducing his immunity.
Painful muscles and joints, allergic reactions, headaches, fever are the typical symptoms of this worm infestation. This parasitic pathology provokes the development of other dangerous diseases that can be fatal.
Tapeworms in pork
Pork tapeworm resembles a flat ribbon, which has a segmented structure. At one end is a spherical head with four suckers. With the help of suckers helminth is attached to the mucous membranes of the intestines. This is a large parasite, as an adult grows to 5 m.
Once inside the body, the worm causes a disease called teniasis in a person. After invasion, along with muscle tissue, internal organs and the brain can be affected. This leads to deterioration of the liver, partial loss of vision, memory, problems with the heart and blood vessels, swelling of the face. Infected people experience weakness, difficulty breathing, pain in the muscles of the legs, loss of appetite, severe pain in the abdomen.
Inside the human body, the growth and development of the parasite larva to adult individuals occurs. These helminths reach sexual maturity in the intestine. Eggs with fragments of parts of the chain are brought out with human fecal masses. There they are released, penetrate the land, water, spreading over large areas. Cysticercosis is a particular danger to human health - infection by the eggs of these helminths through unwashed hands and water.
A pig becomes infected by eating feed. An oncosphere is formed inside its intestines. It represents the invasive form of this helminth. Thanks to the six hooks, the parasites are firmly fixed in the muscle tissue of the animal.
In raw pork meat, such formations are ready to infect humans. They are small and spread through the body through the bloodstream, penetrating into the internal organs and the digestive system.
The parasites inside the beef
Say a little about the bull chain, which should not be confused with the pig. His body consists of a large number of segments. Adults can reach 10–12 m in length, so this species is considered to be the largest representative of intestinal helminths. Particles filled with worms eggs, easily separated and with human feces get out.
The intermediate hosts of these parasitic worms are cattle. Cows can be infected by eating grass in the pasture, feed with helminth eggs. Inside the body of an animal the eggs ripen to the invasive form of parasites. At this stage, the Finns of the round form are localized in the muscles, liver, and lungs.
In beef, the largest number of parasites is concentrated inside the liver, in meat. A person becomes infected by eating foods that are prepared without sufficient heat treatment. Such a worm infestation is called teniarinhoz.
This pathology is accompanied by pain and bloating, nausea, drowsiness. Despite a good appetite, a person has a loss of body weight.
Danger of infection through greasy products
Parasites do not live in fat of a pig, but their eggs can get on it from dirty hands because of violation of the rules of hygiene. In addition, the greasy meat-streaked product also poses some danger in terms of infection, since it is in the meat that parasites can be found.
When a man swallows a helminth cyst, cysticercosis occurs. Such a worm infestation is very dangerous, since the eggs of parasites are very small. Through the circulatory, lymphatic system, they can penetrate into all internal organs.
Of particular danger to human health is damage to the brain and central nervous system. The most severe cases of pathology can be accompanied by epileptic seizures, vomiting. Severe dizziness, headaches, loss of appetite are typical manifestations of the disease.
With the accumulation of oncospheres of parasites under the skin of an infected person visible seals in the form of cones can occur. Treatment of this helminthic invasion should be carried out quickly and professionally, therefore, at the first signs of invasion should be addressed to professionals.
How to visually determine the presence of parasites in pork
The larvae and eggs of many parasites are of microscopic size, so it is almost impossible to determine their presence in the meat with the naked eye. In this case, infected pork often has a normal smell and color. Piglets, adult pigs and wild boars can be ill, therefore any production of pig breeding requires increased attention.
Attention should be paid to seals that can be mistaken for cartilage, bumps covered with a lime capsule, ulcers of unknown origin.
To prevent infection with helminthiasis, it is recommended to purchase pork only in the checked places where sanitary control works on an ongoing basis. Store meat and greasy products best in the freezer.
Of particular danger to the human body are worms eggs, which are characterized by increased resistance to adverse environmental conditions. They do not die even at low temperatures. Due to its microscopic size, parasite cysts freely penetrate through the bloodstream into the internal organs and tissues. There from them appear dangerous for the person larvae. The consequence of such infection is often liver failure, acute pancreatitis.
Is it possible to eat contaminated meat
To prevent infection with parasites, it is advisable never to try raw meat or minced meat. Wash hands thoroughly after contact with these products. For each type of product it is better to use separate knives, cutting boards.
In the process of proper preparation of pork can be a radical way to get rid of parasites. For example, fresh meat should be pre-frozen.
When cooking pork, it is desirable to expose it to a thorough heat treatment. Exposure to temperatures above 70 degrees Celsius kills most worms for a long time. Thus, boil or fry meat products should be on high heat for at least 20 minutes.
A particular danger of helminthic invasions is represented by a variety of delicacies that use half-baked meat products. Thus, chops, steaks with blood, sliced meat, delicious smoked meat, corned beef can be eaten at your own risk.
Prevention of helminthic invasions of pigs
When growing and breeding pigs, it is important to regularly conduct activities that reduce the risk of helminthic invasions. It is necessary to carry out de-worming of animals twice a year. In this case, the sow requires special attention before farrowing, since the parasitic infection is inherited by piglets.
When arranging a pigsty, animal pen, it is important not to allow the interaction of areas where pigs are walking and human excrement can occur. It is not recommended to allow pigs to walk freely outside special pens. Grass, soil, worms can carry parasite eggs, and pigs eat them with pleasure.
The room inside the pigsty should be protected from access by rats, arrange appropriate floors, drains for removal of liquid manure. Periodically it is useful to carry out the analysis of pork feces to identify parasites. When confirming a parasitic invasion, urgently treat the animal. Such activities are of particular relevance before the slaughter of pigs.

Treatment of helminthiasis in pigs
To combat worms in animals, broad-acting anthelmintic drugs are used. These include "Fenbendazol", "Levamisole", "Albendazole", "Febandol". Such drugs destroy the larvae of parasites and adults. Their use will help cleanse the body of worms from worms completely. To avoid unexpected side effects, before using these drugs it is better to consult with experts.
Narrow-acting drugs, for example, Closantel, Nitroxynil, are used to affect adult worms. Some drugs contain several active substances. This increases their effectiveness against dangerous parasites. Timely deworming, health control of pigs will prevent infection of animals and the appearance of parasites in pork.
