To check the herring for the presence of helminths, you need to study:

• viscera (especially intestines);
• caviar;
• gills.

During the butchering of the carcass, an unpleasant smell of rot may appear. It most often manifests itself when the internal organs are taken out of the herring. The scales of an infected individual are slippery and sticky, easily removed when cleaned with a knife. When you press the herring, a characteristic dent may form, which will not go away for a long time.

Infected fish has a specific appearance:

• cloudy eyes;
• mucus on scales;
• swollen belly.

In general, such a herring is by no means to be consumed.

Can you eat raw herring?

Often, fishermen who prefer to eat herring in raw or lightly salted form become infected with helminths. It is the non-compliance with the processing rules that leads to the appearance of worms, which are very difficult to remove. This applies not only to fish products, but also to meat products.

What to do if an infection occurs?

The symptoms of helminthiasis are as follows:

• nausea and vomiting;
• weakness and apathy;
• headache, fever;
• drowsiness;
• an allergic reaction in the form of a rash on the skin (not always).

Herring can be distinguished by their rather small mouth. By the way, this fish does not belong to the category of predators, so it either has no teeth at all, or they are so small and weak that they are rudiments. The tail fin of the herring is divided in two. This fish is found in the warm waters of the tropical and subtropical zones. In the cold seas, herring does not live, does not tolerate temperature.

If you purchased pickled or salted herring, then you should know that it is stored in the dark, because in the light its fat becomes more bitter in taste than it should be.

These acids are much more useful than many vitamin complexes that you can buy at the pharmacy, because it is the use of these acids in food that can prevent many diseases of the heart and blood vessels. By the way, fish is much healthier than dietary meat and is absorbed by the body very well.

If you are in the habit of regularly eating fish in general and herring in particular, then you can be sure that your brain function improves significantly with every bite you eat. In addition, herring is an excellent means of preventing psoriasis. Substances that are found in abundance in fish are able to resist this unpleasant skin disease.

By the way, the fat that is contained inside the herring is able to destroy group A fats that are present in the human body. But it is these fats that provoke the appearance of type 2 diabetes in a person. So, herring can be considered a prevention for this terrible disease.

Of course, it is worth mentioning that omega-3 acids, which, in addition to herring, are found in salmon and salmon, can fight asthma due to the fact that they are rich in magnesium.

What is harmful herring

Most often, we eat not fresh, but salted herring. It is with this factor that all warnings will be associated. Salt itself is very harmful in that it can bind a huge amount of water and prevent it from leaving the body. If you have suspicions of kidney disease, swelling or excess weight, then you should not get carried away with salted herring and salty foods in general.

Salt, which is in excess in the body, is able to penetrate into the blood, which greatly complicates the work of all internal organs through which vessels with such salty blood pass.

Modern man tries to monitor his health and nutrition. Recently, nutritionists have been talking a lot about the benefits of seafood, and in fact, perhaps the most affordable and popular among them is an ordinary herring. Unfortunately, not everyone knows what benefits this fish brings to our body, perceiving it only as an invariable addition to the onion and boiled potatoes.
The triumphal procession of herring across Europe began in the 15th century and continues to this day. Each country has its own favorite recipe for pickling herring, and in Norway, herring is considered a staple food, pies are baked from this fish, snacks, soups, pates and main dishes are made. In this country, the joke is that real Norwegians eat herring 21 times a week.
In Rus', herring has also always been in high esteem, and it was not only salted and pickled, but also baked, fried and boiled.

Today, on store shelves, you can find ready-to-eat herring stuffed with preservatives, flavor enhancers, dyes, which turns this most useful product into a chemical "bomb". Good housewives, fearing to meet harmful additives in the brine or marinade, prefer to buy fresh-frozen fish and salt it at home.
When choosing fresh or salted fish, you need to give preference to whole carcasses with a head and gills.
it is better to buy slack fish "by weight" from barrels, such a herring is easier to evaluate by its external qualities, as well as by its characteristic "herring" smell. Cloudy fish eyes, torn fins and yellow scales covered with spots are sure signs of a stale product.

Masks with the addition of caviar prevent the aging process, restore problem areas of the skin. For the preparation of masks, you must use only fresh product. For example, to prepare a mask suitable for all skin types, to 1 tsp. caviar you need to add 1 tbsp. l. any vegetable (preferably olive) oil, leave the mixture for 15-20 minutes, add half of the whipped yolk, apply on the face and leave for about half an hour.

The fat contained in herring helps to reduce fat cells, adipocytes, which reduces the risk of developing diabetes, which is why herring can be safely called a dietary product.
The use of herring is also not contraindicated for people who monitor their weight, because in terms of the amount of fat this fish is inferior to most meat products, besides, the benefits of fish oil can hardly be overestimated. A person who adheres to a strict diet loses a lot of useful substances that a piece of herring can make up for.
The only drawback of herring, if it is not about cooking fresh or fresh-frozen fish, is a large amount of salt, so it is recommended to soak it in milk, tea or water before use. In addition, in order to achieve effective weight loss, you should not combine herring with potatoes or bread.

diseases of the kidneys and liver, a tendency to edema, high blood pressure, increased acidity of the stomach.

In addition, even in the absence of contraindications, one should be aware of the ability of salt to retain water, therefore, before eating herring and immediately after that, one should not drink a lot of liquid.
How to clean herring
Many people, not wanting to mess around in the kitchen once again, buy ready-made herring fillets, often already cut into small pieces. This is a rather risky choice, because for the production of such fillets, substandard carcasses containing little fat, with an expiring shelf life, are most often used.
Do not be afraid to “get your hands dirty” by carving the herring yourself, this is a fairly quick and simple procedure.
Herring needs to be cut on a board, for convenience, you can lay paper or cling film on it, this will facilitate further cleaning. We make a longitudinal incision on the abdomen, carefully remove the caviar or milk (if any), then remove all the insides. We separate the head, thoroughly rinse the resulting carcass with water, removing all films and remaining pieces of the insides. At this stage, you can remove the paper by wrapping all the waste in it. We make a longitudinal incision on the back, simultaneously removing large fins on the upper and lower parts. We remove the skin, starting from the head of the carcass.
I need to carefully pry off this skin and gently pull it off the carcass in the direction of the tail. We remove the fillet from the fish skeleton, for this, from the side of the tail, you need to pull the halves of the carcass in different directions, eventually dividing it into two parts. If the fish meat does not want to separate from the skeleton, you can expand the incision along the spine with your fingers. At the last stage, all small bones must be removed from the meat, they are well felt by the fingers. As a result of all these manipulations, we should get two pieces of excellent fillet!

HERRING OF HOME SALTING.
Herring (freshly frozen) - 3 pcs. Defrost, gut, cut each carcass into two parts, put in a liter jar "standing". Pour in the marinade.

Features and habitat of herring

Herring is the common name of several species fish belonging to the herring family. All of them are of commercial importance, and are caught on a large industrial scale.

The body of the fish is slightly pressed laterally, and covered with moderate or large thin scales. On a blue-dark or olive-colored back, one fin is located in the middle.

The ventral fin grows directly below it, and the caudal fin has a distinctive notch. On the abdomen, silver in color, along the midline there is a keel, consisting of slightly pointed scales. The size of the herring is small, even small. On average, it grows up to 30-40 cm. Exclusively migratory fish can grow up to 75 cm.

Large eyes are set deep on the head. Teeth are either weak or missing altogether. The lower jaw is slightly better developed and protrudes beyond the upper jaw. Mouth small. Herring may be sea ​​or river fish. In fresh water, it lives in rivers, most often it can be found on the Volga, Don or Dnieper.

In salt water, in impressive flocks, it is found in the Atlantic, Pacific and Arctic oceans. It likes a temperate climate, so it is represented by a few species in very cold and hot tropical waters.

Few people know what kind of fish called Pereyaslav herring. The funny thing is that she has nothing to do with this family at all, although she slightly resembles it in appearance.

In fact, it is a vendace. It was forbidden to catch it, and even more so to sell it, under pain of death. They ate it only in the royal chambers, at various ceremonies. This famous fish is depicted on the coat of arms of the city of Pereslyavl-Zalessky.

The nature and lifestyle of herring

Life sea ​​fish herring runs away from the coast. It swims closer to the surface of the water, rarely dropping even below 300 m. It keeps in large flocks, which it forms during the period of emergence from eggs. Young people, at this time, are trying to be together.

This is facilitated by the initial feeding on plankton, which is always abundant in sea water, so there is no competition. The joint remains unchanged for a long time and very rarely mixes with others.

River fish herring is a migratory fish. Living in the Black and Caspian Seas, she goes to fresh places for spawning. On the way back, exhausted individuals die en masse, never reaching home.

Herring nutrition

Food preferences change in herring during the period of growth and maturation. After leaving the eggs, the very first food for young animals is napulia. Next, copepods enter the menu, growing up, the food consumed becomes more and more diverse. After two years, the herring switches to zooplankton.

Having matured, the herring feeds on what it catches with small fish, crustaceans and benthos. Their size directly depends on gastronomic preferences. Only by switching completely to the diet of a predator, the fish can grow to a suggestible size.

Reproduction and life expectancy of herring

There are many types of herring, so we can say that their spawning lasts all year round. Large individuals rush at depth, and small ones closer to the shores.

They gather during the breeding season in huge flocks, so numerous that, propping up, the lower layers of fish simply push the upper ones out of the water. Spawning occurs at the same time in all individuals, the water becomes cloudy and a specific smell spreads far around.

The female spawns up to 100,000 eggs at a time, they sink to the bottom and stick to the ground, shell rock or pebbles. Their diameter depends on the type of herring. After 3 weeks, larvae begin to emerge, about 8 mm in size. They begin to be carried by fast currents throughout the body of water. Reaching a length of 6 cm, they gather in flocks and keep them near the coastlines.

During spawning (May - June), transitional herring rises upstream of freshwater rivers. The throwing itself takes place at night, while the eggs float freely in the water, without being attached to the bottom. Herring juveniles, having gained strength, begin to move down the river already in order to get into the sea by the beginning of winter.

Herring species

There are many types of herring, about 60 species, so we will consider only the most popular of them. Fish herring mackerel found in the North and Norwegian Seas, where it is caught during the warmer months.

It is a fast-swimming fish, with a lifespan of up to 20 years. She is a predator and therefore grows to an impressive size. Having reached 3-4 years, she goes to spawn in the south-west of Ireland. The most popular delicacy from it is mackerel in sour cream sauce.

The Black Sea herring lives in the Azov and Black Seas, spawning begins in May-June. It feeds on crustaceans and small fish that swim in the upper layers of the water. The average size of this species reaches 40 cm. Catching it is very popular with amateur anglers. Most often pickles this herring fish hit the store shelves.

The Pacific herring lives at all depths. It is large - more than 50 cm in length, and weighs 700 g. Its meat contains the most iodine than other species. It is mined on a huge commercial scale: Russia, USA, Japan. Most often, on photo of herring, you can see exactly this kind fish.

The famous Baltic herring swims in the waters of the Baltic Sea. It is small in size, about 20 cm. It feeds only on plankton, even when it reaches adulthood. In this food fish - herring used more often in salty form.

Another popular representative lives there - the Baltic sprat. These delicious fry are caught even off the coast of New Zealand and Tierra del Fuego. The most popular use for us of this type is canned food.

The most controversial representative herring fish- this is iwashi. The thing is that it belongs to the sardine family, and only looks like a herring. On the shelves of the USSR, this fish came under the brand name "Herring Ivasi", which caused confusion in the future.

In those distant times, the production of this fish was cheap, because its numerous flocks swam close to the coast, but then they went far into the sea, and catching it became unprofitable.

Any fish, including the popular herring, can be a source of worms.

Timely detection of infected fish and proper heat treatment will prevent infection. If a person does not have cooking skills, it is worth excluding this product from the diet.

Found in red: salmon, trout and pink salmon. When using such individuals, it is worth removing the worms and burying them deep in the ground.

Cystidicola farionis lives in the swim bladder of smelt. It has a threadlike and thin shape. Refers to the round type. It does not harm the human body, but it is recommended to remove all internal organs of an individual before cooking.

Spherical, white, trienophorus nodulosus lives in the liver of fish. After the balls are damaged, the worm spins up to 12 centimeters in length. Fish dishes are also prepared at certain standards, the insides are removed.

Thin worms infect freshwater species. These worms are up to 10 centimeters long. They are attached to the gills and under the scales. Outwardly, it looks like veins. This is the only type of worm that is completely harmless and does not infect humans.

Worms dangerous to humans

The meat of pike, perch or burbot is exposed to infection. Grow in the human body can be up to 50 meters in length.

Diffillobotrium dendricitum is a resident of Russian reservoirs. It grows in the human body up to 1 meter. The life cycle is about 6 months. During this time creates a lot of pathologies.

Herring is popular on the Russian table. But, not all manufacturers comply with the conditions of preparation. Therefore, infection with herring is not excluded. It provokes diseases: ligulosis, diphyllobothriasis and others.

If these symptoms are observed in fish, it should not be eaten.

What can you get from fish

Fruits and vegetables ripen in summer. Summer residents enjoy barbecue, and their children play in the sandbox. This is the most dangerous source of human infection with helminths.

All the necessary serums, vaccines and other preparations have been created against infections. But they cannot prevent infection with worms, a person is able to do it.

IMPORTANT! It is necessary to buy dried and dried fish only in stores that undergo sanitary and hygienic control. Purchase from supermarkets that have a water safety certificate.

What can be infected from fish:

• Ligules.
• Anisakidosis.
• Metagonimiasis.
• Nanophyetosis.
• Diphyllobothriasis.
• Clonorchosis.
• Opisthorchiasis.

Ligules

The larvae infect cyprinids. They cause serious harm to the body, damage internal organs.

To protect yourself from infection with this species, a person must have an idea about the appearance of an infected individual. Affected fish have unusual behavior and look different.

This disease affects marine fish. Carriers are crustaceans, mollusks and other small inhabitants of the sea, which are eaten by fish.

When it enters the human body, worms cause swelling, disruption of the motor and secret functions of the intestine, and digestion of food worsens.

People become infected with anisakiasis by eating half-cooked or raw fish, squid, octopus, and shrimp. The sick individual becomes emaciated and weak. The disease can kill entire shoals.

Metagonimiasis

The fish eat sick shellfish. This infection is typical for freshwater fish. Symptoms in humans are nausea, fever, urticaria, and diarrhea.

A sick individual is severely emaciated, soiled with waste products and has an inflamed intestine.

Nanophyetosis

Symptoms are manifested in a sharp weight loss, the skin and mucous membranes of the mouth turn pale. Pain is also felt on the right under the ribs, there is a loss of appetite and dizziness.

Diphyllobothriasis

Symptoms of infection in humans are increased arousal, intestinal disorders, the development of anemia, a sharp decrease in vitamin B12, a headache appears, and appetite worsens.

Fish are infected at any time of the catch, regardless of the season of the year.

Clonorchiasis

With a strong course of the disease, fever occurs, an increase in lymph nodes, muscle pain, allergies, and jaundice develops.

Lack of proper and prompt treatment leads to cirrhosis of the liver and its cancer in 40 percent of cases.

Opisthorchiasis

Individuals of the carp family and predators are susceptible to infection. They have a detrimental effect on the liver, gallbladder. Also on the scales of an individual there may be foreign formations.

An infected person develops a fever with fever, vomiting and nausea, pain in the internal organs of digestion, bitterness in the mouth, depression, severe fatigue.

If symptoms related to the actions of helminths appear, you should immediately contact a medical institution.

Some diseases are not treated on their own, require the appointment of complex measures.

How to prevent infection

There are special methods of prevention to help stop the penetration of worms into the human body. If you follow all the recommendations, it will be possible to reduce the infection to zero.

Moderate or large, rarely small. The upper jaw does not protrude beyond the lower. Mouth is moderate. Teeth, if present, vestigial and protruding. The anadromous fin is of moderate length and has less than 80 rays. Dorsal fin over ventral. The tail fin is forked. This genus includes more than 60 species distributed in the seas of the temperate and hot, and partly in the cold zone. Some species are purely marine and never enter fresh waters, others belong to anadromous fish and enter rivers for spawning. Their food consists of various small animals, especially small crustaceans.

The number of representatives of this genus is colossal, and they play an extremely important role in the fishing industry. Only a few tropical species (Clupea thrissa, Cl. venenosa, etc.) turn out to be (according to Günther, probably in connection with food) extremely poisonous, so that eating them is life-threatening. In general, herring is useful for humans mainly as food, partly for rendering fat or preparing fertilizer.

Particularly important economically real C. (Cl. harengus), sprat(Cl. sprattus), sardine(Cl. pilchardus), Black Sea and Caspian C. (Cl. caspia, Kessleri, Saposhnikovi, delicatula - see Beshenka), shad(Cl. alosa) and trick(Cl. finta), found in the European seas and entering rivers for spawning, mengaden(Cl. menhaden; see), shad(Cl. sapidissima), which is included in masses in the rivers of the Atlantic coast of the North. America, and now bred on the Pacific coast, N. of the North Pacific Ocean (Cl. mirabilis), Pacific Ocean sardine (Cl. sagax), further included in the rivers of the Atlantic coast of the North. America (Cl. mattovocca), S. coasts of Sumatra (Cl. toli), etc. With great success, experiments were made on the artificial breeding of shad (see Fish farming), thanks to which not only it was possible to stop the fall of fishing on the Atlantic coast of the North. America, but also to develop a strong fishery in the Pacific. Various species of S. serve as valuable bait for catching other fish and are indirectly important as food for large predatory fish. The most important is ordinary S.(Cl. harengus; see fig. in the tables under Art. Pisces). It differs from the species closest to it, the sprat (Cl. sprattus), in that 1) the base of the anal fin is less than 3/4 of the distance from the ventral fins to the articulation of the maxillary bone with the premaxilla (more in the sprat) and 2) denticles of the ventral margin 36-48 (for sprat 32-35). In general, both of these species are connected by many intermediate forms. The greatest length (Norwegian and Swedish) is up to 37 cm and 42 cm. The color of the back is steel blue with a green and golden hue, the sides and belly are silvery, the dorsal and caudal fins are dark, the rest are whitish.

Distribution area

S.'s area of ​​distribution embraces Sev. Atlantic Ocean (both near European and North American coasts), in the N to southern Greenland and Finmarken, in the S to the Bay of Biscay. The Baltic Sea with its bay (precisely a small variety called herring), Finmarken and the Murmansk coast and the White Sea (mainly near the west and south coast). Herrings vary quite a lot, but the question of the varieties of these fish remains controversial.

Apparently, the herring spends part of its life at great depths. Its oceanic fishing in Europe begins annually near the Scottish Islands, where the region of relative shallow water begins, and gradually moves further and further to the south. Spawning continues throughout the year and occurs in different places at different times. It is not uncommon to set two separate main periods for the same place; thus, in the Baltic Sea, spawning occurs before summer and after summer, in the ocean - before the onset of winter and at the end of winter. The spawning of large S. occurs at a greater depth (up to 60-100 sazhens), the small spawns closer to the shore, sometimes 1 sazhen. depths and often in less saline parts of the sea. For spawning, S. gather in colossal flocks, sometimes so dense that pressure from the lower fish sticks out the upper ones from the water. The water becomes cloudy, and the pungent smell spreads over a considerable distance. Masses of fertilized eggs fall to the bottom and stick to underwater objects or stick together into clods. The number of eggs is approximately 20,000-40,000. Their diameter in the Baltic S. is usually from 0.92 to 1 mm, in the oceanic S. from 1 to 1.3 mm. Before hatching, it usually takes about 2 weeks, but at high temperatures, development is reduced to a few days.

S.'s food consists mainly of small crustaceans, especially copepods (lat. Copepoda), but small fish also come across in their stomach. The latest research shows that the approach of northern coasts, on which the success of coastal fishing depends entirely, is most closely related to the distribution of water of high salinity and temperature.

Mining method

The main methods are: pelagic trawl, net, ring seine. The main fishing for S. is currently carried out in the North Sea, which is carried out all year round. More than 150,000 people are engaged in this fishing, and the annual catch of S. extends to several billion pieces. In recent years, quota fishing for Norwegian spring-spawning herring has been allowed again. Basically, fishing is carried out in the central part of Norway - in the districts of Møre and Nurlan.

In contact with

When the larva is introduced, the body begins to react with local inflammation. The blood changes its chemical composition due to the production of an increased number of eosonophils, blood cells that react to allergens. The immune system tries to fight the invasion, but to no avail.

Anisakid do not react to the resources of the human body, being neither viruses nor bacteria. They cling to the organ, grow there, feeding on useful substances, and cause many diseases, depending on the location.

• with damage to the stomach - gastritis, ulcer;
• with damage to the liver and gallbladder - hepatitis, obstruction of the bile ducts, cirrhosis, cholecystitis;
• with damage to the pancreas - pancreatitis;
• with intestinal damage - peritonitis, necrosis, intestinal obstruction.

Anisakid are difficult to confuse - they curl up into balls, or circles. Worms are located in salted herring mainly next to milk, intestines, caviar. If you unravel their tangle or simply straighten the circle, it will be seen that they can be up to 6 cm long already in the larval state.

Photo of anikasides in fish:

Herring contaminated with anisakides is allowed to be sold at the legislative level. This is due to the too large scale of infection of the fish and the fact that it is salted without gutting. . In order to minimize the risk of human infection with anisakides, there are rules for processing fish. Before salting it, the manufacturer must freeze the fish and store the freeze at a certain temperature from several minutes to several days. Each fish batch undergoes a sanitary examination.

After freezing, the fish can be salted. The most reliable salting option is steep salting, and not weak salt, aged for 12 hours.

Therefore, in reputable supermarkets, as well as in specialized fish stores, you can buy and eat herring, even if it was infected with anisakids, because by that time they will already be dead. But, the manufacturer of salted fish also needs to be chosen wisely - he must have a good reputation, it is unprofitable for such industries to infect people, otherwise their business will collapse very quickly.

If the herring is bought on the market with hands, then there is a high risk of infection. Then it is better to buy fish, freeze it for several weeks, then salt it yourself.

Anisakids die at low temperatures from 18 to 30 degrees and from high temperatures from 60 degrees. Thus, if freezing, salting or pickling of fish is not expected, then it must be thermally processed within the specified temperature.

Symptoms are nonspecific and can be disguised as a variety of various diseases. The incubation period is from a week to two.

Symptoms depend on the location of the anisakids. If the stomach is affected, then it will be vomiting, stomach pain and all other manifestations of gastritis or ulcers. If the intestines are affected, there will be a picture of intestinal symptoms.

Surgery

Surgical intervention is performed only when anisakiasis causes acute symptoms and complications. Acute pain, fever and nausea may indicate serious complications. An endoscope serves as an instrument for extracting anisakide. Extraction occurs from the intestines, stomach or esophagus.

Even after conservative removal of the worm, monitoring of the state of the body is required for 1 year using endoscopy.

Medical therapy

• Albendazole;
• Vermox;
• thiabendazole;
• Decaris;
• mebendazole;

If a live anisakid has already entered the human body and firmly settled there, it is ineffective to treat it with folk remedies alone. Alternative methods are effective as adjuvant therapy. Also, for prevention, folk remedies can prevent the development of anisakide.

List of remedies for the treatment of anisakiasis at home:

All of the above should be taken in moderation. Despite their natural origin, the excessive use of traditional medicine can lead to complications of existing diseases and allergic reactions. Herbal infusions are always used according to the instructions.
