Red caviar is an expensive product, so most people buy it for the holidays and for other special feasts. It's a shame if, after using it, unpleasant consequences arise, and even more so - diseases. Red caviar, like other seafood, contains various parasites and their eggs. How dangerous they are for humans and how to make the use of red caviar safe, you can find out by reading what parasitologists and sanitary doctors say about this.

Types of parasites

Often, ordinary people do not realize that there are parasites in almost every fish organism. Parasitologists urge not to focus on this, since in the natural environment the presence of such relationships between representatives of different groups of animals is considered the norm. It is important what kind of parasite lives in the fish, since they all fall into two broad categories:

  • Species for which a person is an intermediate or permanent host. Such helminths and nematodes spend a certain part of life or all life in the human body.
  • Species for which the person is not the master. Even when such parasites enter the digestive tract, infection does not occur, since the conditions of the human body are not suitable for the development and functioning of a parasitic organism from this group. In this case, the parasite is removed from the intestines along with the feces.

Even when a pathogenic species enters the digestive system, infection does not always occur. It is more likely with a weakened body or chronic diseases.

All pathogenic nematodes are small in size, as they must fit in the egg. Most often they look like thin worms twisted into a spiral, and it is in this form that they end up on the table, and then into the human body.

Diseases

When eating raw red caviar, several types of helminthiases can be infected. The most common of them are anisacidosis and diphyllobothriasis.

Anisakidosis

Eating sushi, rolls, sandwiches and other dishes with red caviar can lead to the ingestion of anisakid. In humans, they parasitize during only a separate stage - the larval stage, but even during this period of time they are able to harm their intermediate host.

Anisacode larvae are characterized by high resistance to those factors that have a detrimental effect on adults:

  • withstand saline environment;
  • transfer the temperature to + 45 ° С;
  • resistant to short-term freezing at a temperature of -30 ° C.

After ingestion with food, an incubation period occurs, lasting from several hours to two weeks. The further development of events depends on where the parasite settles. If this happens in the small intestine, then asymptomatic or rare manifestations in the form of constipation are possible. The situation is worse when the place of introduction of the larvae is the stomach. Then the following signs of anisakidosis develop:

  • pain in the stomach;
  • urge to vomit and vomiting, sometimes with blood inclusions;
  • fever;
  • irritation and other signs of skin allergy.

The complicated course is aggravated by perforation of the stomach wall and internal bleeding, which requires emergency medical intervention. In rare cases, anisacidosis becomes chronic, causing gradual emaciation, anemia, significant weight loss, etc.

Diphyllobothriasis

Eating insufficiently processed red caviar, a person can become infected with diphyllobothriasis. This disease begins after the fluke helminth, which is in the larval stage, enters the stomach. Fluke eggs show amazing resistance: at temperatures up to 100 ° C, they retain the ability to develop for two years.

After infection, it takes about two months until the end of the incubation period. At this time, the parasite from the eggs develops into a sexually mature individual, which can reach a length of several meters. As a rule, only one fluke lives in the intestine. A person suffering from diphyllobothriasis becomes a source of infection, since parasite eggs are present in large quantities in his feces, falling into the ground or nearby water bodies.

As the parasite's body grows, symptoms worsen. Initially, there is a slight fatigue, weakness, performance decreases, and an allergic reaction on the skin is possible. The more the helminth closes the intestinal lumen, the more digestive disorders appear, the appetite disappears, the pain in the epigastrium increases, and the taste sensations may be disturbed.

Over time, the symptoms are supplemented by anemia, blood pressure periodically drops, hands go numb, the temperature is set from 37 ° C to 37.5 ° C.

The presence of parasites in the bank

According to the law, red caviar is allowed for sale, in which single dead parasites have been found. It can be both adult helminths and their larvae. If caviar has undergone proper processing, then they are inactivated and do not pose a danger to human health. Another question is that after seeing such "content", the appetite may deteriorate, and you will no longer want to use the product.

Prevention methods

In order not to become infected with parasites while eating red caviar, you must adhere to the general rules:

  • do not buy caviar from hands, as it may not be aged at a low temperature in time in accordance with the requirements;
  • during the cooking process, you cannot try raw caviar for salt or spices;
  • do not use utensils that were used in the preparation of red caviar for other manipulations before heat treatment with boiling water, as eggs and larvae of parasites can remain on it.

It should be remembered that many eggs of certain types of parasites found in red caviar retain their viability when salted, so the ambassador cannot be considered a reliable method of disinfection.
