The 5 dirtiest fish in the vegetable market contain a lot of heavy metals and parasites, and the stall owners

Do you know which are the 5 dirtiest fish in the vegetable market? Is the fish you usually eat in your stomach really clean?

In the past, almost every family would have a steamed fish or braised fish as a reserved dish on the dining table during the New Year. Now that everyone’s living conditions are better, go to a vegetable market or order on your mobile phone on weekends, and you can come to a fish every now and then. However, there are five kinds of “dirtiest” fish on the market, and even the fish stall owners themselves would not eat them. Today we will take stock of which kinds.

First catfish.

It is a fish native to the tropics of Africa. Now the common catfish in the market is the native catfish of our country. It is moderate in size and the meat tastes like it melts in the mouth. There are many people who like to eat it. However, this kind of fish has good environmental adaptability, strong disease resistance, and belongs to the scavenging population, and its eating habits can be called abnormal. They can survive in places such as stinky drains or cesspools, and there is almost no inedible food.

In some breeding bases, farmers even raise catfish and livestock together. Usually, there are chickens and ducks on the top, and catfish are raised in a pond below. Usually, they only need to supplement half of the feed of other fish to raise them well. The manure of livestock is a kind of natural fertilizer, which can provide nutrients for plankton in the water, and catfish, as omnivores, are not picky eaters. Fish that grow up in this environment will not have fewer parasites accumulated in their bodies.

Generally speaking, fish without scales like catfish will give people a dirty feeling, so when buying catfish, you must choose carefully, and don’t buy fish that are too dark or have dirty gills, otherwise it will be earthy. The taste is heavy, and heavy metals exceed the standard.

The second eel.

Rice field eel is a fish with greater efficacy, it can regulate blood sugar, and has the effect of nourishing qi and nourishing the brain. The eel has only one big bone in the middle of the back, and the meat inside is very delicious, and many people can’t put it down.

In the wild, rice field eels were everywhere, as long as there is water and mud, there will be traces of them. People like to catch rice field eels in the big ditch by the village or by the small river. At that time, the river water was crystal clear, and there were many small fish and shrimps in it, so the rice field eels caught could be eaten with confidence.

But now the water quality in many places is difficult to guarantee, and various harmful substances in it exceed the standard, and the survivability of rice field eels is relatively strong, and the requirements for water quality are not high, so it is not recommended to continue to use wild rice field eels as food.

The eel was once considered one of the dirtiest fish, mainly because of the many parasites in it. They like to live in hot and humid ponds and creeks. These places are the paradise for the growth and reproduction of gnathostomum nematodes. They mainly attach to the digestive system of rice field eels, so it is very necessary to clean the internal organs when eating.

Jawstostomum can be transmitted through food and mother to child. Its length is only one or two centimeters, and it is easy to be ignored without careful observation. Eating it by mistake can cause epilepsy. Therefore, it is best to eat artificially raised and fresh eels when purchasing. The head of rice field eel is easy to gather harmful substances and try not to eat it. Jawmouth nematodes are afraid of high temperature, so they should be cooked thoroughly during cooking to ensure that there are no worms or eggs in the meat.

The third silver carp.

Silver carp is a freshwater fish in my country. It tastes bland and tasteless. It was very popular in the 1990s because the supplies were relatively scarce at that time and there were few species of edible fish. In addition, it is relatively cheap, but the meat is relatively rough, and the fishy smell is also very strong. This kind of fish was able to meet people’s needs for eating fish in the past, so many people have feelings for it and still eat it now, but its quality is not as good as before.

For the silver carp being cultured now, the general breeder will sprinkle chemical fertilizers in the pool to catalyze the growth of plankton in the water, so that the silver carp can get more nutrition, so it is best not to eat this kind of fish.

The fourth tilapia.

Tilapia is an exotic edible fish introduced in my country in the early stage, and currently there are large breeding bases in Guangdong and Guangxi. Tilapia has the characteristics of fast growth, no picky eaters, fast reproduction, and less disease. It will eat rotting plants, animal excrement, and rotting animals.

After entering my country, tilapia began to multiply in large numbers, which once squeezed the living space of native fish in our country. When fishing in the river, we often encounter a large group of tilapia.

The biggest advantage of tilapia is that there are not many small fish bones in the meat. In addition, its body is flat and its back is high. It is a fish tailored for barbecue, which is very suitable for children and the elderly.

Tilapia is a kind of fish that can live in water. For them, as long as the water temperature is sufficient, it does not matter if the water quality is poor. Therefore, whether the tilapia is dirty or not has a lot to do with its living environment. Try not to eat tilapia caught in the wild, and must choose those fish that have been raised through formal channels and have passed the inspection.

Fifth Scavenger.

It can be said to be one of the most notorious invasive alien species in our country. Because of the beautiful patterns on its body, it has been spread all over the world. Is the scavenger fish edible?

Although the scavenger itself is not poisonous, it is really not recommended to eat them, because the scavenger is just like its name, it really eats everything, even the garbage in the water. It will not only eat the roe of fish, but also the excrement of other fish. It would be good to put one in the fish tank to purify the water.

The harmful substances eaten by the scavengers will accumulate and stay in the body, making the abdominal cavity contain a large number of bacteria and parasites. Moreover, the content of heavy metals such as lead and mercury in the scavenger fish is far higher than that of other fish. If you eat it often, it will easily cause headaches and damage the liver and kidneys. In addition, if the parasites are not treated cleanly, they will enter the human body and damage the nervous system, and even lead to death. The scavenger fish has a very strong survivability and can survive for a long time even in places without water.

We must be careful when buying fish in the vegetable market, because their growth environment or quality is difficult to guarantee. We must keep our eyes open to ensure our food safety
