Can you eat the head of a crayfish, and can you eat the head of a crayfish? Is there really a toxin

The head of the crayfish is not to be eaten.

The circulatory and respiratory and reproductive systems of shrimp are concentrated in the cephalothorax, and the abdomen can be said to be just an organ of locomotion. There are not only many formed eggs in the shrimp head, but also many other crayfish garbage toxins, the head of the lobster is very easy to absorb heavy metals and toxins, because of these reasons, eating the head of the crayfish may cause allergies and acute gastroenteritis, and the head and neck of the lobster are at risk of causing lung flukes.

In addition to the shrimp yellow in the shrimp head can not be eaten, there is a line in the body of the shrimp that cannot be eaten, the black line on the back of the shrimp's abdomen is its intestines, and the inside is of course shrimp poop, which should be removed before cooking. In addition to these, can not eat drunk shrimp, shrimp sashimi and other food, some parasites can shrimp as an intermediate host, take liver fluke as an example, its larvae "cysts" parasitize in the muscles of shrimp, people eat shrimp containing cysts may be infected with liver flukes. People think that they can kill the parasites in the food during high-temperature cooking, but scientific studies have shown that some parasites cannot be killed during the cooking process.

It's best not to eat it. Because there are many harmful components in the shrimp head, general pollutants will accumulate on the head.

If it is a hard substance, it means that it can be eaten.

If the color is darker, the soft substance is the excrement of the lobster, which is not easy to eat.

It is better not to eat the head.

The little dragon is scared and dirty.

And the head is the dirtiest part.

The head of the crayfish is where the most toxins are absorbed and processed, and it is also the part that is most likely to accumulate pathogenic bacteria and parasites. The head of the crayfish is filtered, so there are many bacteria and parasites in the gills. Crayfish head has too many heavy metals and is very harmful to the human body, there are parasites, and some are very harmful to the brain.

Personally, I think that the head of crayfish cannot be eaten, because there are many parasites in the head of crayfish, and there are many heavy metal elements, so it will cause great damage to the body after eating.

The head of a crayfish is not edible because it has a poison sac in its head.

Crayfish heads cannot be eaten, they will contain some heavy metals, as well as dirty things excreted by lobsters, so it is not recommended to eat.

Can you eat the yellow thing on the head of the crayfish?

Crayfish have a strong ability to survive, but if the living environment is very bad, some harmful heavy metal elements in the water are easy to be ingested by crayfish, and then enriched in the head of crayfish, and parasites also like to settle in the head of crayfish, if these parasites are not killed clean, if you can't tell whether the crayfish is clean, then the shrimp head is better to eat less.

Summer is coming, and it's time to eat crayfish and drink beer, but because crayfish is more expensive, it often costs 25-35 yuan a catty, so when we eat crayfish, we are often reluctant to throw away the shrimp head, after all, if the crayfish goes to the shrimp head.

Then there is only that little bit of shrimp tail, and there is not much meat, but if you lose the shrimp head, you will feel unwilling, after all, when you buy shrimp, you can buy it according to the whole shrimp, so can the shrimp head be eaten.

In fact, not only the shrimp head can not be eaten, but the shrimp line can also not be eaten, the reason why the shrimp head can not be eaten is not without reason, specifically in my personal opinion, there are the following reasons.

The first reason is:

Heavy metals exceed, especially wild crayfish, should be these crayfish, usually live in a variety of stinky ditches, small ditches, eat a variety of rotten food, so the head of these crayfish, often heavy metals exceeded.

The artificially farmed crayfish should be a better living environment, and they eat more than a variety of food, so the head of these crayfish, although the heavy metals are not exceeded, but they can not be eaten, after all, when the lobster eats food, there will be many bacteria left in the shrimp head.

The second reason is:

There are too many parasites, especially wild crayfish, which should be a problem for the living environment, resulting in the head of these crayfish and the inside of the shrimp, parasitic many parasites, even if they have been treated at high temperatures, but they can still not eat it.

The artificially bred crayfish will regularly maintain the living environment, so the heads of these crayfish have fewer parasites, but they are not completely absent, so when eating crayfish, the best way is to separate the head and tail of the crayfish, and put the lobster head into the mouth to suck a few mouthfuls of juice.

Finally, when I was a child doing crayfish, I had to remove the shrimp line, after all, how to say, this shrimp line is also the intestine of the crayfish, although it is relatively small, but it is better to remove it, but there are also many lobster restaurants, which do not go to the shrimp line.

If you eat often, it's best to find a lobster restaurant that goes to the shrimp line to eat, after all, safety is important, and when cleaning the crayfish, you have to use a brush to brush the bottom of the crayfish.

The head of the crayfish is not edible. Because the head of crayfish contains a lot of harmful substances in it. Eating it can cause harm to people's health.

Personally, it is recommended not to eat it, because the structure inside the crayfish head is very complex, so it is more difficult to clean, so it is recommended not to eat it as much as possible.

It is best not to eat it, crayfish head contains certain toxins, if you eat it, it is likely to affect diarrhea or other symptoms, so you must not eat it.

Try not to eat the head of the crayfish, the main reason is this:

Although the crayfish we eat on weekdays are delicious, and it seems that the flavor of the soup and the enticing shrimp paste are concentrated in the head of the shrimp; But for the crayfish in the bottom of the biosphere of organisms, all kinds of pollution sources in nature will be directly contacted or absorbed by them, especially the increasingly serious heavy metals and chemical pollution, and these pollution can not be metabolized by the body of the crayfish, so they are generally enriched in the head full of digestive organs, when you feast on these shrimp heads, these pollutants will be enriched into their own bodies, so it is really not recommended that everyone eat shrimp heads again.

If it is a hard substance, it means that it can be eaten.

If the color is darker, the soft substance is the excrement of the lobster, which is not easy to eat.

The head of the crayfish is the digestive organ, so it is recommended not to eat it, because many parasites or undigested food will be in **.

I think I can help you with that. Because I sell lobsters. Lobsters also ate a few truckloads. About what you said. The red substance seen when the lobster head is opened should be shrimp yellow, which is less yellow and softer than the crab's yellow. It's refreshing to eat.

Shrimp yellow, edible.

If it is a hard substance, it means that it can be eaten.

If the color is darker, the soft substance is the excrement of the lobster, which is not easy to eat.

Can't eat.

Most of the heavy metals in crayfish are concentrated in the gills and internal organs, while the gills and internal organs are mainly concentrated in the head.

The real name of the crayfish is "Crayfish", and the scientific name is Procambarus clarkii, which is a kind of freshwater shrimp that is like a fake. It is related to lobsters, taxonomically they are all "decapods", lobsters are lobsters, crayfish or crayfishes, and the crayfish we eat are crickets (so in some areas of northern China it is directly called "crickets").

Crayfish are native to the southeastern United States, so they are also called American crayfish. It is native to the Gulf of Mexico, especially in the Mississippi River estuary, so it is also called Louisiana crayfish.

Crayfish is an omnivore, and its main food is organic matter at the bottom of the water, aquatic plants, algae, aquatic insects, organic detritus, and of course it also eats small fish, shrimp, shellfish and other living creatures, and even cannibalism when it is not full.

Because it eats heterogeneous, it has a strong vitality and can survive in polluted water. But! The crayfish in restaurants are basically farmed. In the breeding environment, animal and plant feeds should be fed according to the needs of growth, such as wheat bran, soybean cake, aquatic insect larvae, etc.

The yellow stuff in the head of the lobster is yellow, and if the lobster is clean, it can be eaten, just like the red and yellow in the head of the city shrimp and the small white shrimp. You can eat it if you want it (it must be clean, don't eat the lobster in the stinky gutter, the head.) )

The meat inside the lobster head is attached to the shrimp torso, which is delicious, except for the hard things, the other parts of the shrimp head can be sucked juice and eat meat.

Eating lobsters is bought alive, even if it is not alive, it is impossible to stay in the sewage, and only those who have never eaten lobster and never seen lobster will have a saying that they can't eat it.

Didn't you feel less scary for a moment?

The yellow part of the crayfish head is its ovaries, which are very nutritious, but because they are rich in cholesterol, people with three highs should be cautious about eating it. These crayfish were brought to us at that time, and everyone thought they were lobsters in the sea, but they were just smaller. Because lobsters are more expensive in everyone's impression, his batch of crayfish has been booked by many hotels!

Xiamen University Chemical Genealogy Analysis and Instruments Key Laboratory of the Ministry of Education published a ** article that the content of heavy metal elements in shrimp head is significantly higher than that of abdominal muscles, and the heavy metal content of crayfish is generally the abdominal muscles of shrimp head. From a health point of view, it is not recommended to eat the head of a lobster.
