Can you eat a crab just after it died, and can you eat a crab that has just died?

Why can't dead crabs be eaten.

So why can't dead crabs be eaten? According to the living habits of crabs, it is not recommended to eat dead crabs. Crabs love to eat rotten food, and pathogenic bacteria and toxic substances accumulate in their bodies.

Dead crabs can quickly grow a large number of bacteria in their bodies, so they should not be eaten, especially in hot weather.

First of all, from the taste point of view, the crab loses its original umami after it dies. There is also a histidine substance in the crab's body, histidine is easy to decompose, histamine and histamine-like substances can be produced under the action of decarboxylase, and the midgut gland will quickly fall apart after the crab dies, and the histidine and digestive enzymes in it will decompose the crab meat. Therefore, the taste of dead crabs is strange and the taste is greatly reduced.

Secondly, the crab itself is non-toxic, but after the crab dies, after the crab's shell is damaged, the protein in the crab's body will breed bacteria, and the infected bacteria in its body will multiply, and the bacteria may produce toxins. Dead crabs are likely to be poisonous.

Again, the crab's body is easy to carry heavy metals, after the crab dies, the midgut gland will quickly fall apart, and the digestive enzymes in it will decompose the crab meat, the intestinal gland is relatively easy to enrich heavy metals, and the heavy metals will also come out to produce pollution after it rots.

Finally, if the crab has not been dead for a long time, it can still be eaten after being refrigerated, remember, it is refrigerated and not frozen, and the sea crab is better than the river crab, because the living environment of the river crab is worse and there are more bacteria.

How to eat crabs.

So how can crabs be safe and healthy to eat? We should pay attention to the fact that when cooking crabs, it is advisable to add some perilla leaves and fresh ginger to detoxify crabs and reduce their coldness. Crabs can be steamed, boiled, fried, or made into snack fillings.

When steaming crabs, the crabs should be tied up to prevent the legs from falling off and yellowing after steaming. When removing the shell of raw crabs, blanch them with boiling water for 3 minutes, so that the crab meat is easy to remove and is not wasted;

Then, we will buy back the crab without rinsing with water, put it into a clean tank, jar, add two eggs with broken shells with brown rice, and then sprinkle two handfuls of black sesame seeds to submerge the crab cover, and then cover the mouth of the tank with a cotton cloth to make the air circulate, but can not make the crab see the sun, so that the crab can be raised for about 3 days to take out, because the crab absorbs the nutrients in the rice and eggs, the crab belly is strong and plump, the repetition is significantly increased, and it tastes fat, fresh and fragrant. Crabs are easy to move the wind, so they are not easy to eat cold; In addition, dead crabs should not be eaten.

If the crab has just died, the meat inside has not deteriorated, so it can still be eaten, and if it is steamed, it can be eaten directly.

Yes, freshly dead crabs will not cause harm to the body, and the various nutrients of crabs are still there, so freshly dead crabs can be eaten with confidence.

It is best not to eat freshly dead crabs, because after death, crabs accumulate a lot of toxins in their bodies and cannot be excreted, and their proteins are particularly susceptible to spoilage. At this time, if we eat it, we may experience symptoms such as diarrhea or abdominal pain. In particular, the biogenic amines produced in the crab body are very harmful to the human body.

Therefore, for some seafood products, try to focus on fresh and fresh, and try to eat less after overnight to avoid affecting the body.

Crabs that have just died, if the crabs do not smell, it proves that the crabs have not rotted, so they are edible, and if you are really not at ease, you can add a little more ginger.

OK. If the crab has not been dead for a long time, the meat will not spoil and can still be cooked, but if it is too long, it must not be eaten.

Dead crabs produce large amounts of histamine in their bodies. Histamine poisoning occurs when humans eat dead crabs. Because histamine is an allergic poison, it can also be said to be allergic food poisoning.

Don't think it's okay to eat just a little bit of dead crab meat. People who are allergic to histamine can cause a reaction even if they take a bite. For example, after eating a dead crab for 10 minutes and 3 hours, symptoms will appear, such as redness of the cheeks, flushing of the chest and the whole body, and conjunctival hyperemia of the eyes, as well as headache, dizziness, chest tightness, general fatigue and irritability.

It should be noted that a crab of 3 taels and 4 taels can only eat 60 grams and 80 grams. The dietary guidelines for Chinese residents recommend that each person consume 40 grams and 75 grams of aquatic products per day, so do not eat more than one crab per day.

People with allergies, hyperuricemia or gout, pregnant women, the elderly, children, and the infirm should eat less or no crabs. If you are caught by a crab, you should immediately rinse the wound with water, disinfect it with iodine, and if the redness and swelling do not go away and the bleeding does not stop, you should go to the hospital immediately.

01 No, you can't.

Crabs cannot be eaten when they die, because after the crab dies, it will cause many pathogenic microorganisms and parasites to multiply. If you eat dead crabs, it will cause a high incidence of intestinal infectious diseases and cause diarrhea, which is harmful to health. The protein and other nutrients in the dead crab have been decomposed and consumed, and if you eat it again, it will not play the role of supplementing nutrition, and its nutritional value will be greatly reduced.

Crabs cannot be eaten when they die, because after the crab dies, it will cause many pathogenic microorganisms and parasites to multiply. It is an omnivore that likes to eat the rotting carcasses of plants and animals, with a large number of bacteria and viruses. The metabolism of live crabs can compete with microorganisms and inhibit their reproduction; After the crab dies, the microorganisms will use its rich nutrients to multiply rapidly, causing the crab to spoil and produce a variety of toxins.

Food poisoning symptoms such as fever, vomiting, abdominal pain, and diarrhea may occur after eating.

Crab meat also contains a type of histidine, which turns into histamine when the crab dies. Histamine is a sensitizing substance, which can dilate blood vessels, resulting in allergic symptoms such as **, mucosal congestion and edema, urticaria, nasal congestion, runny nose, bronchial asthma, nausea and vomiting, abdominal pain and diarrhea, and in severe cases, circulatory collapse. The crab is dying or just dead, and its inhibition capacity decreases, producing this histamine and toxin.

In addition to dead crabs, everyone should not eat drunk crabs and crabs of unknown origin.

Many people think that drunken crabs can be sterilized and disinfected after being soaked in high levels of liquor, and it is no problem to eat them raw. However, the crabs living in streams and rocky beaches are likely to have a parasite called "cysts", and the alcohol in the liquor cannot kill the parasites, if you eat drunk crabs raw, the parasites enter the human body, and can pass through the intestines to the lungs in the abdominal cavity, and in severe cases, they can parasitize in the brain, liver and other organs, causing organ cysts.
