Worms in crayfish( photo) When choosing such a favorite treat as cancers, many wonder if there are worms in cancers?

Doctors warn: even fresh crayfish meat can be infected with worms( it can be seen in the photo), which cause paragonism.This helminthic invasion is transmitted only from crayfish and crabs.If they are not sufficiently digested before consumption, the larvae of the parasites will penetrate the human body and cause the disease.

Cooking delicacies should be at least 5 minutes in boiling water, or better - 10 minutes.The taste of meat does not deteriorate, but all the larvae of the parasites will die.It is necessary to remember that only prolonged heat treatment saves from paragonimosis.


Also in the outbreaks of paragonimosis in the water can be pieces of dead crabs and crayfish with viable worm larvae.During swimming in rivers, lakes, accidental ingestion of water should be avoided.Paragonimosis can be prevented by using only boiled or purified water.Control over access to open water bodies should be carried out

by sanitary-epidemiological services in order to prevent mass infections by parasites.

What are worms in cancers?

Tape trematode in cancers The parasympathetic ribbon fluke( on the photo).Arthropods are temporary hosts of these helminths.Man - the ultimate host, it is in his body is the growth and reproduction of this parasite after ingestion of food infected with the larvae of the worms of crayfish.After swallowing the larvae from the intestine, they enter the bloodstream, and from there directly into the lungs.In rare cases - in the brain or in the kidneys.Initially, the disease occurs almost without symptoms, during this time the parasite develops and multiplies.And only from the second-third week of the disease there are a number of symptoms:

  • high temperature with figures up to 39-40 ° C;
  • headache;
  • general weakness;
  • vomiting;
  • chest pain;
  • shortness of breath;
  • is a wet cough that contains an admixture of pus and blood.

After a few months, the chronic stage of the disease begins with alternating periods of worsening and relief.The disease can last up to two to four years.

Swallowing of worms into the brain leads to inflammation of the brain membranes( meningitis) or a volumetric process that resembles a tumor.

The ingestion of worms from cancers into the lungs rarely results in a tragic outcome.With timely access to help and the right treatment, the outlook is relatively favorable.If helminths suddenly hit the brain, the frequency of deaths increases significantly.


Paragonimosis, which caused larvae, has a complication - spontaneous pneumothorax, bleeding, purulent and inflammatory processes in the lungs.
