Fish is a healthy food highly recommended by nutritionists, but howbuy fish, Eating fish is a science. If you don’t pick it right, it will not only taste unpalatable, but also pose a safety hazard. So which fish cannot be bought?one personwater manufacturerWarning, you should think carefully when encountering the following types of fish!
1. Cod in the cafeteria
The cod in the cafeteria is unlimited, but what makes people wonder is: is this really cod? After all, cod is very expensive in major supermarkets.
However, this is not the main thing. Aquatic producers say that some cafeterias will put whiting on their tables. However, dragon cod is not a real cod. It is commonly known as “oil fish”. After eating, the wax and fat in it cannot be absorbed by the human body. The body will excrete it again, which can easily lead to “butt oil leakage” and diarrhea.
2. Salmon in the cafeteria
Cheap salmon is questionable because salmon is generally imported from abroad, with prices starting at more than a hundred yuan per 500 grams. However, the color of rainbow trout meat is similar to salmon, and the price is less than one-third of imported salmon.
In addition, the hygienic conditions of the “salmon” in the cafeteria were too poor, such as the ice cubes were not replaced, the fish was contaminated by customers, and the refrigeration was not in place, leading to parasites.
3. Frozen fish with soft flesh
Aquatic dealers said that few people would buy the whole fish for some relatively large fish, especially deep-sea fish, which will die after coming out of the water. For this reason, merchants will use cutting and freezing methods to facilitate sales and transportation.
However, such fish meat is easy to be defrosted repeatedly, causing the fish meat to become loose. Moreover, during the repeated thawing process, the fish meat will oxidize and bacteria will multiply, causing the fish meat to deteriorate.
4. Dead fish with bulging belly
Aquatic products dealers said that when buying fish, if they find that the fish is dead and the belly of the fish is white and bulging, they need to sell it quickly and the price is very low.
Because, after a fish dies for a period of time, its abdomen will swell due to the proliferation of bacteria. If the weather is hot, damage and explosion may occur. Not only does this fish have a peculiar smell, but it is also full of bacteria and toxins.
5. Fish with incomplete scales
If the fish scales are incomplete, on the one hand, it indicates that it was hit during transportation. On the other hand, it means that the fish has been stored for a long time, or the skin has been infected, causing the fish scales to fall off.

6. Fish with bad smell
The aquatic product dealer said that he would fish or buy wild fish when he had nothing to do, but he would never go to the pond next to the factory. He never eats some wild fish that smell of kerosene, gasoline, and pungent smells, because these fish are contaminated. I would rather eat farmed ones than eat them.
In addition to the precautions mentioned above when buying fish, you should also pay attention to the following points when choosing fish:
(1) Look at the firmness of the fish meat. Press the fish body with your fingers. The fresh fish meat will be firm and elastic, and the dent will disappear quickly. The slower the dent disappears, the worse the freshness will be.
(2) Look at the anus of the fish. The abdomen of fresh fish is normal and not distended, and the anus is white and sunken. On the contrary, the belly of the fish is swollen and the anal hole is protruding, indicating that it is not fresh.
(3) When buying marine fish, pay attention to the integrity of the fish and whether the fish meat is loose. Aquatic products dealers also said that you should buy fish early as the fish in the aquatic product market in the morning is fresher and there are fewer dead fish.
