"Eat four legs, it is better to eat two legs, eat two legs, it is better to eat no legs", here there is no leg, referring to fish, although this is only a folk saying, but also from the side of the previous people, think that the food in the water seems to be more nutritious, but after modern scientific and technological research, it also confirms that this sentence does have a certain truth.
Many foodies are also particularly fond of legless fish, and the raw fish is always talked about. Raw fish, is sashimi, the production is very simple, directly cut fresh fish into slices, and then dipped in seasoning to eat, smooth and delicate taste, conquered the taste buds of countless people, China's most famous fish raw, is the Guangxi Hengxian fish raw, fish raw in addition to raw materials, knife work is also very important.
The history of Chinese fish eating can be traced back to the pre-Qin period, through many dynasties, several times prosperous, forming a rich fish food culture.
However, although the fish is delicious, the way it is eaten raw is at risk of contracting parasites, which also causes many people to have to endure the pain of cutting love and abandoning this delicacy. But some people insist that freshwater fish have parasites, and marines don't have to worry about parasites because there are no parasites in the sea.
So are there any parasites in the sea? Can you eat seafood raw fish or sashimi with confidence and boldness?
First of all, parasites can be said to be almost ubiquitous, and the behavior of their parasitic hosts has always made people feel very disgusted, after all, most people feel uncomfortable when they see parasites, let alone humans infecting parasites.
Parasites do exist in the sea, but the parasites in the sea are very different from those in freshwater.
First of all, parasites are inferior organisms, they do not have a good ability to regulate osmotic pressure, in other words, parasites in the ocean, in fresh water will soon rise and die, after all, their lives, mainly around a variety of fish and other sea creatures around, never thought that they can also come to the human body to walk around, and the human body osmotic pressure environment, and the marine environment gap that is called a big. Just like marine fish put into fresh water, they will also die, in addition to the problem of seawater pressure, another major reason, the solute quality of seawater and freshwater is different, that is, the balance of body fluid salt concentration is changed, so marine fish will also die after a period of time.
In this way, most of the parasites in the ocean, even in the human body, are difficult to survive. So can we safely eat seafood raw? No, don't get too excited too soon!
There are exceptions to everything, there is a parasite called xenoderma in the ocean, its adaptability is super strong, can parasitize in the human body, although humans are not suitable hosts for xenocephalus, but the larvae can parasitize various parts of the human digestive tract, causing visceral larval migration.
According to the literature, nearly 30 countries around the world have reported human cases of isalamic nematode disease, with a total of more than 30,000 cases and an upward trend, of which Japan has the largest number of cases, with more than 2,000 new cases per year. Moreover, gastrointestinal heterocuspid nematode disease, there is currently no specific treatment drug, can only use fiber gastroscopy and remove the worm body, if necessary, surgical treatment!
So friends, don't cause yourself pain in order to experience the silkiness of that moment. So how can you avoid annoying parasites and eat delicious seafood?
There is no doubt that setting up an iron pot, managing it seawater and fresh water, boiling it is all protein. However, the small partner who loves seafood must not agree: cooked? Isn't this a tyrannical creature? Reject seafood without a soul.
For the sake of foodies, the technology emperor thought of a way to solve the parasite problem, using the "FDA standard low temperature freezing" treatment, you can ensure that all pests are removed and eaten with peace of mind. But the taste does make some differences, after all, it is not as fresh as catching it from the water, but the fish and the bear paw cannot be combined. It should be noted here that this is not ordinary freezing, and the idea of wanting to use the refrigerator to freeze seafood at home is recommended to dispel, after all, the refrigerator does not have enough low temperature and time standard requirements.
Therefore, in general, there are parasites in seafood, but because they are more fragile than parasites in freshwater, and as long as they are properly treated, they can be eaten with confidence, if you are still worried, it is recommended to eat a piece of deworming medicine.
In addition, when we choose to eat raw fish, we must pay attention to choosing regular stores, after all, some bad merchants will use the so-called "freshwater salmon" to impersonate! Freshwater salmon is actually a rainbow trout freshwater fish, and "serious" salmon is Atlantic salmon, although the sashimi cut out of the two is almost the same from the outside, but if there are parasites in these sashimi, it can be a big trouble, so it is also important to choose a store.
