Worm infestation is a danger that many neglect or pretend not to. Worms not only disrupt the performance of human organs, but also poison the body with the products of their vital activity.

Are there worms in marine and freshwater fish?

Before discussing whether there are worms in fish, I would like to cite some extracts from the regulatory document approved by the Ministry of Fisheries back in 1988 and which has not lost its relevance in our time.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

The document is called "Methods of parasitological inspection of marine fish and fish products (raw sea fish, chilled and frozen fish)"

This is an extract from an official document. The title of the document is given in full, and those who wish to familiarize themselves with it in detail can find it on the Internet.

Is it possible to eat such fish

If the quality of the fish is alarming, it is better not to buy it. In lightly salted, dried, smoked fish there is a large number of worms. Any deviation from fish cooking technology is fraught with dangerous consequences. Eating such fish is strictly prohibited! Recently, rolls and sushi have become very popular.

Few people think that red fish, which gives sushi and rolls such an unusual, piquant taste, is not subjected to heat treatment. The likelihood of contracting worms found in such fish is close to 100%. Is it worth the risk?

What can be the consequences

The consequences, after eating fish infected with worms, can be not only sad, but also tragic. It is naive to think that worms live only in the intestines and do not do much harm. These parasites penetrate into all human organs, leading to a variety of consequences.

Larvae and adults are found in the lungs, brain, liver, heart. The movement of larvae through the bloodstream is especially dangerous. Worm infestations can be fatal. Unfortunately, these cases are not isolated. The biggest danger is that helminths can live in the human body for years.

To poison the body for years without giving away. Feeling unwell, fatigue, decreased immunity is just the surface of the iceberg. Worms such as a broad tapeworm grow up to ten meters. Rolling up in the intestine, they block its lumen, and intestinal obstruction occurs. In this case, only surgery can save lives.

Another type of worms, such as the Chinese fluke, have suckers and are held with their help by the intestinal wall. This often leads to deformation of the nerve endings, and as a result - necrosis. It is not easy to destroy them in the body.

When they die, they release toxins, which also lead to serious complications. Therefore, in addition to deworming, it is necessary to take funds that will help remove dead worms from the body.

What to do with fish with worms

If worms are found in lightly salted, dried, smoked fish, the answer is unequivocal: it is strictly forbidden to eat such fish. In other cases, you can subject the fish to a thorough heat treatment.

Heat treatment recommendations:

  • Spread the fish along the ridge.
  • Cook for at least 20 minutes.
  • Fry - 20 -25 minutes.
  • Bake fish pies for at least 30 minutes.

With such processing of fish, the worms die completely, and you will not get any harm from the much needed and valuable product.

There is one more, no less effective, way to destroy worms in fish. This is deep freeze. The fish should be kept in the refrigerator for 5 days, at a temperature not exceeding - 20 ° C.



In modern refrigerators, it is allowed to set the temperature of the refrigerating chamber to -24 ° C (set independently using an electromechanical regulator), but in the warm season, deviations from the set temperature are possible.

If you are not sure that this temperature is constantly maintained, store the fish in the refrigerator for up to 2 weeks.

What fish are free of parasites and worms

Unfortunately, all fish, in any bodies of natural origin, are infected with parasites. The exception is fish bred in artificial reservoirs, where measures are regularly taken to prevent fish diseases.

Worms in aquarium fish

Aquarium fish also suffer from worms.

Infection methods:

  • Through live food.
  • From untreated water.
  • From new, purchased fish.

Prevention:

  • Live food must be kept in water for several days in order for the parasites to escape naturally.
  • Clean the water thoroughly before pouring it into the fish.
  • Keep new fish in quarantine for 2-3 weeks.

For humans, the worms of aquarium fish are not dangerous. The temperature of our body is detrimental to the parasites of aquarium fish. And they do not eat them. To prevent infection, it is enough to wash your hands with soap and water after various manipulations with the aquarium.

Don't be reckless! Follow all the recommendations listed in the article.
