How to deal with seafood is the safest, are crayfish really dirty?

Seafood is rich in nutrients, but it can also be a bacterium, which will cause great damage to the human body, that is, Vibrio vulnificus, which may be life-threatening in severe cases. Now I watch a lot of variety shows, seafood is eaten raw directly, and raw octopus is popular in South Korea, Japan and other placesIt is recommended that you still don't imitate it, first, the taste is really not as delicious as it is on TV, and second, no one will be responsible for you if you are sick. In addition, Japanese raw food is also processed in a way, and it is not directly fished out of the sea and put on the table.

When dealing with some raw seafood, such as crabs, shells and other marine creatures with hard shells, which may scratch their hands at any time, be sure to wear gloves to avoid injury, in case of injury, you can not take it lightly, you must wash it with water at the moment, once the infection appears, you must go to the hospital, can not resist, so as not to cause greater danger. It is recommended that the seafood is still thoroughly cooked before eating, not to mention that other people will be fine if they eat it, you are not afraid, then there is a way, please do your own convenience. After all, life is one's own, and outsiders can't force it.

Crayfish are not as scary as the Internet, wild crayfish have very low requirements for the living environment, but now the crayfish eaten are more artificially farmed, and the living environment has also improved a lot.

The meat of crayfish is actually very small, and it is a bit laborious to eat, but it still can't stop everyone from loving it. However, the head of the crayfish has a lot of bacteria and parasites, so don't eat the head when you eat it, if you like the taste, you can drink a few sips of soup after eating, and the taste should wake everyone up. There are also shrimp lines, you can pay attention to them when eating, there are many shops, because the business is booming, the shrimp lines are not removed, the shrimp lines are the excrement of shrimp, needless to say, everyone knows how dirty it is.

Now crayfish is the standard for the public to have a late-night supper, and the troubles of drinking beer and eating crayfish are all gone.

The seafood is fresh, just wash it, and there is nothing to deal with the safest. Crayfish are dirty!

It is best to soak seafood in salt water before eating, which is conducive to the discharge of toxic substances in the seafood, and crayfish are indeed a little dirty.

The seafood must be brushed and then boiled at high temperature, so that the crayfish are not dirty.

It is rumored on the Internet that crayfish are grown in stinky ditches, but the edible crayfish are farmed and will not be too dirty.

Seafood must be pulled out of the small intestines in the body, otherwise it will look very dirty, and crayfish are indeed somewhat dirty.

A: Of course you can eat it, as long as you clean it.

1.Pinch the head of the crayfish with your hands, cut off the right tongs first, then the left tongs, and soak them in clean water for two minutes.

2.Pinch the head of the crayfish, turn it over, wash the belly as much as possible, pinch the tail with your hands, twist it from side to side until it is disconnected.

3.Hold the twisted tail carapace, then slowly pull it out, pull out the intestines, cut off the 1 3 of the crayfish head, use the tip of scissors to dig out the black sac-like object in the head, the shrimp stomach, and then clean the crayfish head to remove the dirt, be careful not to wash off the yellow paste.

It's clean that way.

In the early years, crayfish had various rumors comparable to urban legends, such as excessive heavy metals, pregnant women should not eat, microorganisms exceeded the standard, and so on. These are unfounded rumors or untenable! However, the better the environment of crayfish farming, the cleaner it is, the less active heavy metals and other bacteria will be, the meat quality will be much better, and its rich vitamins, proteins, etc. are also good for pregnant women!

Therefore, when choosing crayfish, you must choose a place with a good breeding environment for crayfish, and crayfish farmed by regular manufacturers.

Crayfish can be eaten as long as it is cleaned up. Nowadays, many people eat crayfish, and many restaurants sell it.

Whether crayfish are dirty or not depends on the specific living environment. A small number of wild crayfish may grow in poor water quality and environment, resulting in a dark and dirty belly. And now there are very few shrimp in the wild environment, and there are not many such shrimp that look dirty.

Most of the shrimp on the market are farmed with clear water and grass or caught in the lake, with a very white belly and basically no too dirty crayfish.

We all know that crayfish itself is relatively dirty, and it generally needs to be cleaned and processed before cooking. Most people will buy crayfish from the supermarket, and since crayfish can be more cumbersome to handle, some people will want to buy processed crayfish. So are the crayfish in the supermarket well handled?

Let's take a closer look!

Generally, there are only processed shrimp tails, and there will be no processed whole shrimp.

When buying crayfish in the supermarket, most of them buy fresh whole shrimp, this kind of shrimp has not been processed, and it needs to be bought home to clean and process. And in order to ensure the freshness of the hail crayfish, the supermarket will not dispose of the crayfish, if it can't be sold, it will deteriorate and spoil after a long time, which will lead to a certain loss, there is a certain risk, so in order to reduce the risk and ensure the freshness of the crayfish, the supermarket will not sell the whole crayfish that has been processed. However, some supermarkets will sell processed shrimp tails, which are mostly peeled off from crayfish that are about to die or just died, and then frozen and preserved, which will be relatively cheaper.

Add water, just submerge the crayfish, add an appropriate amount of white rice vinegar, and soak for 2-3 hours. White rice vinegar can soften the shrimp shell, the acidic environment can also kill some bacteria, and stubborn stains will be easier to clean off after a while. Use a special brush (don't use a laundry brush because laundry detergent is toxic) or a steel wool ball to scrub the lobster and lead the whole body.

Especially on the abdomen, brush until you can clearly see the shrimp line and the whitening of the abdomen.

There is indeed a lot of sediment on the crayfish, and the lobsters that are bought home can be soaked in water for three hours, and then the body of each crayfish can be brushed with a brush.

The crayfish should be brushed clean with a brush, it is best to cut off the head of the crayfish with scissors, take out the shrimp line, and rinse it with clean water.

There is no evidence that crayfish carry schistosomiasis, lung flukes or are contaminated with heavy metals. In addition, both schistosomiasis and lung flukes are afraid of high temperatures. Therefore, crayfish can be eaten with confidence as long as they are cooked at high temperatures.

Crayfish are freshwater organisms whose main diet is microorganisms in the water. Therefore, if it is not bred in captivity, it is recommended not to eat it lightly.

The crayfish has almost no other organs in its body except for one intestine, and all the organs are concentrated in the head. These include the stomach, liver, heart, a pair of seminal or ovarian nests, excretory organs, antennal glands, and bladder and excretory holes. To put it simply, eating shrimp head is equivalent to eating shrimp excrement, semi-digested shrimp food, and drinking shrimp urine.

Secondly, consider the environment in which the crayfish grow. If the crayfish is in a bad growing environment, the shrimp head will be enriched with heavy metals in the environment and polluted by parasites in the water environment. Become a host for parasites such as schistosomiasis, liver flukes, etc.

All in all, the shrimp head is the place where the most toxins are absorbed and accumulated, and it is also the part that is most prone to the accumulation of pathogenic bacteria and parasites. From a health point of view, it is indeed not recommended to eat the head of shrimp. The crayfish itself is difficult to clean, and most of the crayfish on the market are simply cleaned to remove the sediment on the surface of the crayfish.

The head and gills of crayfish are difficult to be cleaned, so the shrimp head has become the dirtiest place for crayfish. You can't touch this thing, or at least don't touch it.

Note!!! Here are the key points, circled to be tested!!

If you have to eat, it is recommended that you must feed it with water for about 24 hours before cooking and processing, so that the crayfish can spit out metabolites. In addition, the body should be washed with a brush of sediment, and at the same time, the intestines must be removed, and then thoroughly washed with water 2-3 times.

The protein content in crayfish is higher, and the content of trace elements such as zinc, iodine and selenium in shrimp meat is also higher than that of other foods. And the taste is good, so in recent years, crayfish has become very popular in many cities. Some places have even set off a "red storm" of summer dining.

The investigation showed that there was no evidence that crayfish carried schistosomiasis, lung flukes or were contaminated with heavy metals. In addition, both schistosomiasis and lung flukes are afraid of high temperatures. Therefore, crayfish can be eaten with confidence as long as they are cooked at high temperatures.

Explanation of terms: Crayfish, the scientific name of crayfish is Crayfish, also known as red crayfish or freshwater crayfish. Professor Cai Shengli of the School of Fisheries of Shanghai Fisheries University introduced that crayfish are native to North America, and in 1918, Japan introduced crayfish from the United States as bait for breeding bullfrogs.

During World War II, crayfish was introduced to China from Japan, and has now become an important resource in China's freshwater shrimp, widely distributed in the middle and lower reaches of the Yangtze River.

According to Professor Wang Xichang of the School of Food Science and Technology of Shanghai Fisheries University, the protein content of crayfish is high, accounting for about 16-20 of the total, the fat content is less than 0·2, and the content of trace elements such as zinc, iodine and selenium in shrimp meat is higher than that of other foods. In addition, crayfish can also be used as medicine, which can dissolve phlegm and relieve cough, and promote the healing of wound muscle after surgery.

You can eat it, if you don't feel dirty, you can use clean water to keep them alive for three days, let them be cleaned and cleaned, and you don't have to look at it with a strange eye at the beginning of the food, so it is better not to eat it than to increase the psychological burden.

Crayfish are relatively dirty, and after buying them, they must be disposed of well and cleaned one by one.

Now crayfish are farmed. It's just that its living conditions are not so demanding. Now farmers in order to improve the quality of lobsters. Therefore, the breeding conditions will not be bad. Eat with confidence, I also love to eat 0,0

The crayfish can be eaten after being cleaned.

As long as you don't eat your head, it's fine.

You can eat it, it's all artificially bred now. Wash well.

I also like to eat crayfish, so I've been thinking about it a lot.

Just knowing it, I searched it, and there are two points of view:

1. As a biological invasive species, crayfish invaded China with the Japanese invasion of China, and Japan was introduced from the United States earlier, and the varieties introduced into China have been genetically improved. Crayfish mainly live in ponds, ditches and other places, and have strong survival and reproductive ability, and with the daily decrease of natural waters, they have begun to switch to large-scale artificial aquaculture. Because of its adaptability and ability to survive in strongly polluted water, the Japanese cultivated it and carried out biological improvement, and its main use is to treat urban sewage, use it to absorb heavy metal elements in sewage, and use it as a green first sewage treatment process to use ......

2. Shrimp farmers say that crayfish like to live in clean places, like stinky ditches, crayfish can't grow big.

Due to the cooler weather, the time suitable for shrimp fishing in the ditch is short. And it doesn't make much economic good. Therefore, most of the crayfish on the market are mostly crayfish caught in the lake area.

At present, the best crayfish in China's market are mainly produced in Dongting Lake, Poyang Lake, Honghu Lake, Hongze Lake and other lakes. Taking Dongting Lake as an example, the daily output in the peak season is about 30 tons, and 5678 is about 3600 tons in four months. Together with several other lake areas, the total production of these major producing areas in the peak season is around 17,000 tons.

This is basically the same as the current annual consumption of 20,000 tons of crayfish in the country.

To sum up, I think:

It should be true that this kind of crayfish is used by ** people to treat sewage, it has a strong ability to survive, and it hides dirt and dirt;

Most of the crayfish we eat are caught in the lake area, and they are not as heavily polluted, dirty, and heavy metals as the legend says;

If you want to eat crayfish, it's best to make it yourself, wash it and handle it well, what you make in a restaurant is not reliable.

Now that it's the season to eat crayfish again, there must be many people who have heard that crayfish grew up eating garbage and carrion, so they are scared and dare not eat crayfish again.

Genetic engineering is a --- that only emerged after World War II
