4hw.com.cn: in summer, you can drink beer and eat seafood without oysters. Generally speaking, it's better not to eat oysters. The oyster opening is likely to indicate that the oyster has died. It is easy to breed a lot of bacteria and microorganisms and is not suitable for further consumption. Let's take a look at it in detail!
What makes an oyster open
Oysters usually open in two ways:
1. Oyster lack of water leads to lack of oxygen. It will open its shell slightly to absorb oxygen. Generally, oyster will survive when it starts to open, but it will die if it lacks water for a long time.
2. If the oysters are not preserved properly, they are likely to die. Generally, the dead oysters will also open their mouths.
Can oysters be eaten with their mouths open
Oysters die of opening and cannot be eaten.
Oyster is a kind of seafood, which has a large number of bacteria parasitism, and it is rich in protein. Once the oyster dies, a large number of bacteria decompose the protein, and the metabolites such as cadaverine and histamine appear. Eating is not good for the body, so the oysters that die at the mouth can't eat, but the oysters that don't die at the mouth can still be eaten.
How to judge the life and death of oysters
1. Generally, the shell of living oyster will be tightly closed. When breaking the shell, there is a clear sense of adsorption force. When breaking the shell of dead oyster, there is no strong sense of adsorption.
2. If the oyster shell is slightly open, gently tap the shell of the oyster, and the living oyster will be quickly closed, while the dead oyster will be still.
3. Put the oyster on the fire and bake it. If the closed oyster shell opens, it means that it is a living oyster. If there is no reaction, it means that it is a dead oyster.
What's the effect of eating an open oyster
If you eat the oysters that are opened but not dead, there will be no discomfort. If you eat the oysters that are dead, there may be the following situations:
1. Diarrhea, oyster itself has a certain degree of bacterial parasitism, the dead oyster in a large number of bacteria breeding, prone to diarrhea caused by Luoluo virus breeding, eating will have diarrhea.
2. Anaphylaxis, the catabolism of cadaverine and histamine after the protein in oyster is decomposed by bacteria, in which histamine can cause anaphylaxis.
3. Food poisoning, oysters in a variety of parasitic bacteria, if there are bacterial metabolites with a certain degree of toxicity, food poisoning may occur after consumption.
What to do with an oyster
1. After eating the oysters, you can drink some warm water, which can promote the metabolism of oysters or bacteria. It is better to supplement some vitamin C, because vitamin C has the effect of enhancing the anti allergy ability.
2. Secondly, in case of diarrhea, if the diarrhea is mild, you can wait for the food in the stomach to be emptied. If the diarrhea is serious, you need to go to the hospital in time for treatment.
3. If there is allergy, you can take some antiallergic drugs. If there is edema in the respiratory tract, you need to go to the hospital in time.
4. In case of nausea, vomiting, dizziness and weakness of limbs, you need to see a doctor in time.
Can oysters be cooked without opening
Oysters should not be eaten until they are cooked.
Generally, live oysters will open their shells when they are cooked. Those oysters that have not opened their shells after they are cooked are likely to have died long ago. There are a large number of bacteria on them, so it is not recommended to eat them. Eating them is likely to cause discomfort.
