What is a salmon fish? How to define it? How dangerous is the use of fish infected with tapeworm?
Recently, recipes are increasingly common on culinary sites, where one of the ingredients is raw fish. It is believed that in this form it retains the maximum amount of useful substances. However, there is such a product is completely unsafe, because it can be solitary.
What it is?
Tapered (celery) is a fish that is infected with a tapeworm, a tapeworm. Even as a larva, it penetrates the body and actively parasitizes in it, feeding on blood with subsequent penetration into the tissues and organs of the abdominal cavity.
Another name for the parasite is the Lenta fishfish. Its length can reach from 20 centimeters to several meters, width - about 15 millimeters. With the help of suckers, which are located on the head of the parasite,it clings to the walls of the abdominal cavity in a fish or intestines in a person and feeds on all the substances necessary for its vital activity.
What does a salmon fish look like?
The easiest way to recognize solitary fish while it is in a pond. An individual infected with a tapeworm swims at the surface of the water, sometimes turning upside down. If you catch her, she almost immediately dies. But how to determine whether a fish is a solitary, in the case when it is bought in a store? Only in appearance will make it quite difficult.
In some cases, a fish infected with a parasite has a distended abdomen. In this case, when pressed from it may seem like a tapeworm. And only when gutting such a fish will be able to reliably determine whether it is infected or not. Most often, the tapeworm with suckers is fixed on the walls of the abdominal cavity, reaching a huge size in length.
Gutted fish of saliva, the photo of which is presented above, carries a danger to humans, animals and birds. Even when a parasite is removed in meat, its larvae can remain, which is almost impossible to detect with the naked eye.
Why do infected fish float on the surface
A fish cannot fully live and develop if there is a tapeworm in it. Increasing in size, the tapeworm leads to the fact that the organs of fish become constricted. The swimbladder shrinks and, as a result, the affected individual can no longer actively swim and even stay in the water, as before. The fish more often floats to the surface and spends several hours in this state.
Do not be very happy if you can see such a picture in the pond when the fish itself goes into the hands. A person who owns all the necessary information should think about why the salmon fish swims on the surface. The most common cause of this behavior is a dangerous disease - ligulosis caused by a tapeworm.
What fish are prone to illness
Solitaire, as a rule, lives in freshwater bodies. Therefore, river fish are susceptible to infection. Gustera, roach, bream, bluebite and even pike most often become the habitat of the tapeworm.
As the parasite larva grows and develops in the body of the Cyclops crustacean, which is food for fish, it turns into a full-fledged parasite only after it enters the body.Aquarium species are also susceptible to this disease. In their abdominal cavity pest enters the composition of live food.
The fish aquarium fish, the photo of which is placed above, is not dangerous to humans. It is the same as the inhabitants of reservoirs, swims belly up on the surface of the water, and has no aesthetic value.
What is the danger of the salmon fish? Major versions
There are two opinions about whether solitary fish is dangerous. The first is based on the fact that the parasite Lentets lives only in the abdominal cavity of the fish, and does not pose any threat to humans. When gutting, it is simply pulled out and thrown away, and then you can safely use the carcass for its intended purpose.
Another opinion is based on the fact that even after processing the abdominal cavity, the tapeworm larvae remain in the meat, which, if ingested, cause a serious disease.
The larvae of the solitary fish, which is food for river birds, through time with excrement, again fall into the water. This is dangerous for other fish, because it can cause infection of the inhabitants of the entire reservoir. In order to prevent infected individuals are caught, and birds that are carriers of the disease, shoot.
Swimming in a pond with solitary fish
The active period of the disease falls on the end of spring and summer. Since at this time the swimming season opens and continues, it is possible that a person is in the same body of water where the salmon fish lives. Can I swim? Is there a chance of infection?
Tapeworm fish infected with a tapeworm and swimming in the same body of water with a person pose no danger to him. Tapeworm parasitizes the abdominal cavity of fish and the intestines of humans. That is, he can get into it only by eating soliter meat for food.
Sometimes when swimming or fishing you can find a fish on the surface of the water that is similar in description to a solitary fish. In this case, it should not be left in the pond, because it will become an easy food for the birds, and then, together with the excrement, will fall back into the water, and the circulation will be repeated.
Consumption of contaminated meat
What to do if a fish infected with a tapeworm was found in the catch? Is it possible to eat fish sal?
With careful processing, solitary fish may not be dangerous to humans. In order not to worry about what will happen if you eat the salmon fish, you need:
- cook it for at least 30 minutes;
- fry in small pieces so that there are no wet areas in it; stand on each side for at least 15 minutes;
- freeze for at least a day at a temperature of 18 degrees below zero; at higher temperatures, the freezing time should be increased to 10 days;
- keep in plenty of salt for at least 14 days.
If you follow all the recommendations, the fish of choice (you can eat it after processing) will not do any harm to a person. Even if the tapeworm larvae were in the meat, they die during high-quality heat treatment. After that, the fish can be eaten in any quantity.
Salted infected fish
Fully cooked and roasted fish does not pose any danger to humans. But is salting fish salted? Will microscopically turn larvae into large worms, hitting the human intestine?
Salting solitary fish is possible, but you should follow certain rules:
- When dry salting, the amount of salt should be at least 20 percent of the weight of the fish. In undisturbed form, it is salted in 10-14 days, with a ragged belly - in 7-12 days.
- With cold salting, the temperature of which is about 5 degrees above zero, the fish is considered ready to eat after 6-12 days.
- When hot salted, at a temperature of about 15 degrees above zero, the fish is salted for 5-10 days.
At the same time, experts are of the opinion that the safest fish is boiled. Cooking time after boiling is 30 minutes.
It scares many people when worms look like long white ribbons stir in the gut in the guts. They do not dare to use such fish for cooking and can give it to pets or street animals. It is absolutely impossible to do this, as the tapeworm enters the body of a cat or dog and begins to parasitize in it. Tapeworm fish should be disposed of: put in a plastic bag and thrown into the garbage disposal so that it does not get to the animal.
The fish in which the parasite was discovered right on the fishing trip should also be disposed of. If you let it back into the pond, it will become an instant prey for birds. Then their excrement with the larvae will get water, become the food of Cyclops crustaceans, which, in turn, are food for fish. Suspicious individuals are burned or buried.
Signs of infection
In humans, several types of tapeworms can parasitize. One of them is a wide (fish) tapeworm (tapeworm).The reason for the infection is poorly processed salmon fish. How to determine if an infection has occurred? Attention should be paid to the following symptoms:
If you identify these signs and suspected infection with tapeworm, you should immediately consult a doctor who will prescribe the appropriate treatment.
Prevention of the disease in humans
It is impossible to completely exclude a purchase or catch of a solitary fish, since it is quite difficult to identify the parasite by external signs of the parasite. But in order to prevent human infection, you must adhere to the following prevention measures:
- Carefully inspect the fish before buying, pay attention to the swelling and density of the abdomen. Sometimes when pressed on it, the worm can crawl out.
- Do not buy pre-gutted fish, because to check whether it is infected with tapeworm, it will be impossible.
- When buying an advantage should be given to fish grown in artificial ponds. In such conditions, its food is artificial food. In addition, in specially equipped reservoirs, prophylaxis against parasites is carried out.
- When a tapeworm is detected, depending on the degree of its fastidiousness, the fish must either be thrown away or carefully processed.For this purpose, freezing at a low temperature, good cooking or salting for a long time is suitable.
- Infected fish meat and the more entrails can not be fed to domestic animals.
- After processing the fish, thoroughly wash all kitchen utensils that were used.
- It is strictly forbidden to eat raw river fish!
- Do not buy salted fish, because unscrupulous manufacturers do not comply with the terms of salting. There is a high probability of infection with tapeworm.
There are different opinions about whether the fish is dangerous. You can eat it or better utilize it, depends on whether a person wants to risk his health for the sake of a tidbit of fish. After all, even a small inconspicuous larva, hitting the intestine, can turn into an adult tapeworm. Be careful. Health to you!
