The number of worms in raw fish has increased by almost 300 times

Parasitic worms are organisms that are able to penetrate other living beings and to live at their expense. They exist , but recently American scientists were particularly interested in the worms of Anisakis simplex, which are also known as "herring worms". These creatures first infect marine fish, and when they eat dolphins and whales, starting in full parasite inside the larger mammals. Recently, American scientists have found that between 1962 and 2015 the number of infected worms fish increased 283 times. The question arose — why the population of parasites has increased dramatically and why are they dangerous to humans and animals?

The Answers to these questions shared the publication , citing scientific journal . An increase in population of parasitic worms Anisakis simplex the scientists found, when he examined the data from the 123 research papers. If you believe the information found in 1962, the number of infected worms fish were hundreds of times less than in 2015. This is pretty scary news, because once in the body of a human or animal, worms can cause the development of dangerous diseases. Described in the scientific work of herring worms, for example, cause a disease called antacids.

Anisakis — a disease caused by parasitic worms of the family Anisakidae, which are Anisakis simplex. Its symptoms include abdominal pain, nausea, vomiting, high fever and diarrhea. When complications of the disease causes damage to the intestines and internal bleeding.

Worms in fish

According to scientists, parasitic worms Anisakis simplex strike almost all fish, including herring, cod, perch and salmon. Since these fish are often used in raw form in the preparation of sushi, the risk of human infection by parasites is always high. However, a specialist in water and fishery resources Chelsea wood believes that people can still have favorite foods and not worry. The fact that in the preparation of sushi, the fish is carefully checked in the presence of parasites. Besides, during cooking other dishes as the fish is cooked in the oven, and at high temperatures the worms simply die.

Except that dolphins and whales can't cook, so eat the fish raw, along with parasites. Within marine mammals, herring worms of length up to 6 cm roll up and brazenly taken away from the animal vitality. If a lot of worms, the infected dolphins and whales could eventually die. With a population of whales in the world is all right, but on the planet are dolphins, which are on the verge of extinction. For example, the so-called Hector's dolphins (Cephalorhynchus hectori) today there are only 7000 individuals.

One would assume that parasitic worms have begun to proliferate due to global warming. But Chelsea wood believes that the reason for the increase in population "herring worms" is that in 1972 in the United States and many other countries banned the hunting of whales. A huge population of marine mammals has begun to recover and increase their numbers increased and the number of parasitic worms.

due to parasitic worms dolphins Hector can completely die

And if the reason for the growth in the number of parasites was global warming, active reproduction would not only Anisakis simplex, but other worms. The researchers found that the population of parasites of Pseudoterranova, which affects sea lions and other pinniped animals, since 1962, almost unchanged.

there are a huge number of dangerous worms. They can penetrate into our body along with the meat . Also worms can live .

What is the result? Rare species of animals today die not only , but also in the form of parasites. In addition, given the results of the study, lovers of sushi should be more careful because the risk of infection of worms, though not high, but still there. Well, in the protection of animals, it turns out, can have their negative effects — the ban on whaling was the cause of the increase in the number of parasites. How to solve this problem, alas, is not yet clear.

In the raw fish it is possible to meet parasitic worms Anisakis simplex
