Hello everyone, I'm your old friend - Trick Little Supervisor!
Most fish is rich in nutrients and has a sweet and delicate taste, so many people like to eat fish. But you know what? In daily life, these 5 common fish can not be eaten indiscriminately, because these fish are not only very dirty but also contain heavy metals, eating not only without any nutrition, but also bring a heavy burden to the body, some fish eat a bite will be incontinent, and even a bite of "death", these 5 kinds of fish specifically refer to? Let's take a look together.
(1) Egyptian catfish
Catfish because of its surface without scales, fish bones are relatively few, belongs to a very typical fish with less spines and more meat, its taste is very delicate and rich, the most important thing is that there are many practices, so it is loved by people, and it is also very common on the daily table.
But you know what? This fish is very dirty. Because this is a fish with strong vitality, it can not only survive in a low-oxygen environment, but also survive in septic tanks and smelly gutters, and the environmental requirements are extremely high. In addition, catfish is a fish with a very complex diet, garbage, animal carcasses, and various feces are its "recipes", it can be said that any "garbage" can be collected in full.
It is precisely because this fish receives all the environment and food, therefore, this fish contains a lot of parasites and heavy metals, if it is wild or Egyptian catfish, everyone must not eat it. Usually when you go out to buy this kind of fish, you must also identify it, artificial breeding can be eaten, but don't be greedy for cheap, see cheap and buy, this will be very dangerous.
(2) Leopard fat body catfish (scavenger)
When it comes to leopard fat body catfish, many people may not know, but when it comes to scavengers, many people should be familiar with it. It is not an exaggeration to say that it is a water scavenger, because it sees what to eat, can survive and reproduce rapidly in any environment, is an alien species in the country, has been flooded, and it is self-evident how dirty it is.
However, despite this, some fish markets in Africa or Vietnam are very popular, and even some barbecue restaurants sell scavengers, if you see a sale, do not try it easily. According to relevant data, the bacteria, pollutants and heavy metals in the body of this fish are seriously exceeded, and regular consumption not only has no nutrition, but also may die.
(3) Tilapia
Tilapia is delicious and rich in nutrients. In foreign countries, tilapia has always been known as "chicken in water", and has even been recommended by many experts as the preferred recipe for women during lactation.
However, this fish has a strong ability to survive and reproduce, and it is also a very complex fish, so wild tilapia often live in a very poor water quality environment, which will lead to tilapia's body containing a lot of pollutants, while enriching a variety of heavy metals harmful to the human body, human consumption will damage health.
Of course, this tilapia artificial farming technology is very mature, and tilapia purchased through normal channels can be eaten with confidence. Never go outside to catch or buy tilapia from unknown stalls, otherwise there are greater health risks.
(4) Dogfish
The mouth of the dogfish looks like a duck, so it is also called duckfish, which is relatively rare in our country, and the so-called scarce is expensive, so the price of this fish is quite expensive. But if you think expensive things are good things, you're dead wrong.
This fish likes to eat smelly fish rotten shrimp, like chicken manure, duck manure, cow dung and other animal feces are also its favorite, as long as any feces, garbage, rotten meat that falls into the sight of the dogfish will be eaten by it, so it can be said to be the aggregate of all heavy metals and pollutants, if we humans eat it, it is equivalent to concentrating the pollutants and heavy metals of the dogfish into our body, and over time there will be some "poisoning" symptoms, so it is best not to eat dogfish.
(5) Yellow eel
As a rural person, the most exposed to yellow mud since I was a child, it can be said that yellow eel was also a playmate when I was a child. Every time the season of ploughing and planting the field, I like to follow my father to catch yellow eels, at that time the family was poor, there was almost no money to buy meat, so I could only catch field chickens, catch fish or this yellow eel, etc., stew some porridge and cook some soup to eat as a tonic.
But now the environment is different, living conditions are better, this wild yellow eel we almost do not eat, because wild yellow eel lives in yellow mud, there are many parasites, the most common parasite is called jaw nematode, iron worm, etc., jaw mouth nematode even high temperature is difficult to kill completely, it is said that it can be latent in the body for 10 years, very dangerous. Therefore, it is recommended that everyone keep their mouths shut and do not continue to eat even if they are delicious.
Today I will introduce the 5 dirtiest fish in the world, if it is absolutely useful after reading, remember to like the collection and share it, so that you can help more people.
Well, that's the end of today's sharing, we'll see you next time, thank you.
