US, WASHINGTON (ORDO NEWS) — Scientists from the University of Washington said that over the past 37 years, the number of parasites in fish has increased by 283 times.
During the study, data were collected for the period from 1978 to 2015. The number of Anisakis parasite worms in raw and undercooked fish has been studied.
Anisakis is often called the herring worm, but it is found in many marine fish. When ingested with food, the parasite in a person multiplies in just a couple of days.
Individuals penetrate the intestines, after which nausea, diarrhea, and vomiting are felt. This condition is called an acidosis. Symptoms disappear only after the parasites die.
Based on the words of scientists, usually in the preparation of sushi, chefs remove parasites from fish fillets. But for dolphins, seals and whales, everything is much more complicated.
After entering animal organisms, parasites actively multiply there and again fall into the waters of the ocean.
Scientists attribute the increase in the population of Anisakis to the active protection of marine animals, so that there are worms where to breed. Also among the influential factors, experts noted air and water pollution.
