The opinion about river fish is widespread today, as a breeding ground for worms. Consider what helminths can live in it and what to do in order not to become infected with them. Almost invisible larvae of parasites that live in river fish can cause quite dangerous diseases.
Pike may be infected with larvae of such worms that provoke diphyllobothriasis - a disease that affects the intestines, is caused by a wide ribbon.
Pike plays a major role in the spread of diphyllobothriasis in nature, but other predator fish, such as ruff and perch, can be affected by it. Pike is more susceptible to infection with these worms, more often it is eaten in insufficiently processed thermally or chemically, so people are more likely to get sick of this helminthiasis from it. Larvae of broad lentils are found in internal organs, muscle fibers and pike roe.
Symptoms of invasion with the use of pike with worms will manifest themselves after a long period, from 20 to 60 days. The disease begins to manifest gradually. Primary manifestations are attacks of nausea, vomiting, belching, heartburn, decreased appetite, diarrhea. Next, pallor of the skin, fatigue, weakness, abdominal pain, enlarged liver, cracked tongue join. There may also be rashes on the skin, cramps, numbness of the limbs, unsteadiness of the gait.
If such symptoms are detected after eating pike, immediately consult a doctor for timely diagnosis and treatment.
Another type of disease is trienoforosis. These worms parasitize the pike in the intestines( in the photo), less often in perches, omul, grayling, catfish. The liver, sometimes other internal organs, are affected. They appear to be 2-4 cm in length and 2-4 mm in width. Trienophore is most common in lake and river fish, but it can also affect marine life.
Glysty at the crucian carp
How do the worms look like in carp? An example in the photo. These and other river fish can have parasites such as:
- Ligula or belt is a large banded worm up to 70-80 centimeters long, 3-4 cm wide. This type of worms is found in lacustrine carp. Larvae of the helminth enter the intestine of the carp and other river fishes as food. Further, the larva penetrates through the intestinal wall into the blood and from here into the abdominal cavity, where it turns into an adult, reaching large sizes, causes swelling or rupture of the belly. Sometimes a part of the worms stick out from the belly. Karasis, affected by Ligulidae, are suitable for food only after evisceration of the abdomen and sufficient heat treatment;
- Nematodes that cause phyllometroidosis. These are pinkish-red helminths, which are located on the head or pectoral fins of carp and other carp, as well as perch. The size of these worms is up to 10cm. They accumulate in the liver, kidneys, swimming bladder. They are not dangerous to humans, but it is undesirable to eat fish contaminated with them, including carrots and perches, as the meat becomes watery, friable, loses its flavor and nutritional qualities;
- Flukes causing post-dysplasia. This disease can affect the carp, carp, carp, voblu, perch and others. In infected individuals on the body, fins, gills, you can see black dots. Each such point is the place in which the capsule with the helminth is located. Being in the body of crucian carp or perch, these parasites do not emit toxins that are dangerous to humans, so fish, stricken with post-ampullosis, can be eaten;
- The opisthorchiasis can be infected by eating raw or untreated fish. Mostly carp family. Penetrating into the human body, the worms develop and cause symptoms such as headache, abdominal pain, fever. It affects mainly the gastrointestinal tract, liver and pancreas. Eating fish contaminated by the larvae of these worms is permissible only if it has undergone sufficient heat treatment( cooked or fried).
How to identify carp with worms? Visually you can see only those parasites that accumulate in the region of the gills and fins, but the individuals located in the body are much harder to identify.
Wormholes in perch
In perches there are some helminthiases that are described earlier - postodiplostosis, opisthorchiasis, diphyllobothriasis, ligulosis, and other diseases.
Methorhosis affects the liver, the gallbladder of a person. Infection occurs when eating raw or inadequately thermally processed fish such as crucian carp, perch, roach, carp, and others. Larvae of worms in river fish are found in muscles, gills, in the shells of the eyes.
Gnathostomosis is helminthiasis, which upon penetration into the human body is in the subcutaneous adipose tissue, lungs, liver and other organs. People can get sick with the use of contaminated raw fish, such as carp, crucian carp, perch.
In sea bass you can find such a helminthiasis as anisakidosis. The average length of anisakid is 50-60 mm, the body is spindle-shaped, purple-red in color. Larvae of worms in sea bass are in the abdominal cavity, on the surface or inside the internal organs and in the muscles.
A person becomes infected with anisakids when eating seabass, herring, squid or other seafood contaminated with larvae. In the human body, these parasites affect the gastrointestinal tract. Prevent contamination can be the right culinary processing of seafood.
