1. Nutritional value of hairtail

As a hairtail that often appears on people's tables, it has attracted a large number of loyal diners with its plump and tender meat. Compared with other spiny fish, hairtail has very few bones, only one bone in the middle of the spine, and no other small fish bones, so it is very convenient to eat and is therefore popular with many people. However, as a seafood, hairtail often hides some parasites. If we eat them without distinguishing them, it can easily pose a threat to our health. Marine fish has always been regarded as a high-quality food ingredient because of its rich nutritional value and delicious taste, and hairtail is one of the best.

(ii) Some hairtails contain parasites

However, while enjoying the delicacy, many people do not know that hairtail may contain parasites that are harmful to the human body. Most people can understand the phenomenon that freshwater fish have parasites, but often think that marine fish will not be affected by parasites because they think that parasites will not exist in high-salinity seawater. But in fact, although some parasites cannot live in sea water, nature is so magical that there are other parasites hidden on the surface or inside the bodies of various fish. If people accidentally eat these foods containing parasites, it will undoubtedly affect our health.

3. Classification of parasites

As a kind of marine fish, hairtail is inevitably affected by parasites. Generally speaking, the parasites hidden in hairtail are mainly nematodes. In terms of classification, nematodes belong to the same category as the well-known roundworms, and are also a type of parasite that is widely distributed in major sea areas. If people eat hairtail containing this parasite, it will cause acute tissue swelling, bleeding, nausea, abdominal pain and even other inflammations. Moreover, these parasites have very strong reproductive abilities. Once they are in a suitable environment, they will reproduce in large numbers. If they are not dealt with in time, they are likely to spread to other foods.

In addition, there is a symbiotic relationship between parasites and the human body. Once they enter the human body, these parasites have the ability to change the human condition and cause more serious harm to the body. Not only will it compete with the body for various nutrients, thus affecting the normal development of the human body, but it will also invade various organs, secrete some substances that are harmful to the human body, and further affect the functioning of human organs. Moreover, parasites often cause the host, that is, humans, to have a hypersensitive reaction in the host's body, resulting in a loss of immune system function.
