2. If the fish cannot be eaten, it is recommended to minimize the storage time, and if you want to save it, you should put it in the refrigerator to freeze it to prevent the growth of bacteria.

3. If it is in the refrigerator, there is no problem, but you have to eat it after it is hot, and don't eat it again if you can't finish it, because after reheating, the fish is easy to deteriorate, and the protein is easy to decompose into ammonia, etc., so it is not recommended to eat it after reheating.

In fact, the fish that has been eaten overnight can be eaten as long as it does not deteriorate. However, because the fish is cooked and put for a period of time, the nutritional value of the fish will change, and the nutrient loss is more, coupled with the easy production of protein degradants, this substance will damage the function of the liver and kidneys. After the fish is left overnight, it is easy to produce protein degradants, which will damage the liver and kidney function.

Therefore, it is better to eat less or no fish overnight to avoid affecting the body.

2. If the fish is really not finished, it should be frozen in the refrigerator for preservation to prevent bacterial growth. When the fish can't be eaten, it is recommended to minimize the storage time, if it must be stored overnight, it is best to put it in the refrigerator to prevent the growth of bacteria, but before eating the next day, it must be completely heated before eating, but if you still can't eat it this time, don't eat it again, because after reheating, the fish will be more likely to deteriorate, and the protein is easy to decompose into ammonia, etc., damaging the body. Therefore, it is not recommended to consume it again after reheating.

But there is a situation of fish, it must not be overnight, this kind of fish is the fish that has completely died when buying, because the dead fish itself has no nutrition, plus overnight, so it is even more useless, so if you don't buy fresh fish, but buy vegetables made of dead fish, it is best to eat it on the same day, and don't keep it if you can't finish eating.

It is best not to eat the fish after 3 nights, because the overnight dish will produce nitrite for a long time, and if the nitrite content exceeds the standard, it will cause cancer, so try to eat less overnight dishes.

Can you eat a fish that dies overnight The explanation is as follows:. 1. Edible: If the fish dies overnight, but it is processed just after it dies, and it is directly placed in the refrigerator for sealed preservation, or placed in the freezer layer of the refrigerator.

The fish meat does not have any peculiar smell or mold, and the fish meat in this state is edible. Because the refrigerator is cold or frozen, the lower temperature can effectively slow down the growth of bacteria, and secondly, the fish is not left for a long time, so the possibility of spoilage is low.

2. Can't eat: If the fish dies overnight, it hasn't been properly treated, and it's kept at room temperature. Especially in the hot summer, it is easy to cause bacteria to grow, so that the fish meat will spoil, and there will be a foul smell or smell, in this case, the fish meat is not edible.

Secondly, the fish is not sealed and stored in the refrigerator, and it is not recommended to eat it because there are other bacteria in the refrigerator, which will infect the fish and spoil the fish, and if you eat this kind of fish, it is likely to cause nausea, vomiting, diarrhea, adverse reactions and other related symptoms of the digestive tract.

Fish must be selected mainly fresh fish, which should be sealed immediately after slaughter and then stored in the refrigerator, which can greatly reduce the possibility of spoilage.

You can feed it once after 9 a.m. and before 4 p.m., and eat it within 5 to 10 minutes each time. Feed less on rainy days, and not at night. Because fish need to consume more oxygen to digest food, the air pressure is lower on rainy days and at night, and the oxygen dissolved in the water is also low, so feeding the fish may lead to severe hypoxia in the water and the fish will die.

This is why most of the dead fish occur at night.

Goldfish can be distinguished by the color of the fish feces: if the fish feces are green, brown or black, it means that the fish body is suitable for feeding and is well absorbed. If the fish droppings are white, it indicates that the fish are overfed and the amount of food should be reduced.

It is also important to note that the food must be clean. Feeding unclean fish food can easily lead to fish diseases. Although goldfish prefer live food, and goldfish fed live food grow faster, live food grows in polluted water environment, which is very easy to be contaminated with germs, so live food should be cautious.

It is recommended to buy branded frozen fresh food produced by professional companies, such as blood bloodworm and prawns, supplemented with beans and vegetables to maintain comprehensive nutrition. Bread worms are also a favorite live food for goldfish, and their nutritional value is also high, so they can also be fed appropriately.

As long as the fish does not deteriorate, it can be eaten, but because the nutritional value of the fish will change after being cooked for a period of time, the loss of nutrients is more, and it is easy to produce protein degradants, so it is better to eat less fish overnight to avoid affecting the body.

When the fish can't be eaten, it is recommended to minimize the storage time, if it must be stored overnight, it must be refrigerated in the refrigerator, so as to prevent the growth of bacteria, but before eating the next day, it must be completely heated before eating, but if you still can't eat it this time, don't eat it again, because after reheating, the fish will be more likely to spoil, and the taste will be more fishy afterward.

But there is a situation of fish, it must not be overnight, this kind of fish is the fish that has completely died when you buy it, because the dead fish itself has no nutrition, plus overnight, so it is even more useless, so if you don't buy fresh fish, but buy vegetables made of dead fish, be sure to eat it on the same day.

Fish that has been left overnight should not be eaten the next day. Fish and seafood are prone to protein degradants after overnight, which will damage liver and kidney function, so they should be prepared and eaten freshly, so it is best not to eat them.
