Can crayfish be eaten or not?
Crayfish may indeed carry parasites, but this is not exclusive to them. Other aquatic organisms can also carry them, such as frogs, snails, and shellfish. , fish, water chestnuts, etc. are all acceptable. The key to preventing parasitic diseases is to cook them thoroughly (a safer approach is to cook them at 100 degrees for more than 10 minutes). In particular, do not eat raw or undercooked crayfish. Crayfish prefer clean water, but because there are fewer organisms in clean pure water, slight pollution-free sewage is more suitable for crayfish to survive. Really polluting the water quality will only reduce the survival rate of crayfish and slow their growth. Although crayfish eat rotten food, their strong stomach force can quickly decompose the toxicity of organic matter and excrete it with their feces. They will not accumulate toxins in the body due to eating garbage.
Crayfish are indeed very adaptable to the environment and can survive in heavily polluted places. However, most of the heavy metals it ingests are transferred to the shell. As it continues to grow and shed its shell, these heavy metal toxins are removed from the body, so the heavy metals in the meat may not exceed the standard. Some research data shows that in addition to the shell, heavy metals in crayfish are mostly concentrated in the gills and internal organs, and the gills and internal organs are mainly concentrated in the head. The tail we eat does not contain too many heavy metals, so the possibility of causing poisoning is unlikely.
However, you should still pay attention to eating less from roadside stalls. The preparation may cause hygienic conditions. Eating it may cause diarrhea and illness. You may feel more at ease if you go to some authentic stores.

A few days ago, we received I received a letter from a viewer. The viewer said in the letter that he wanted to report the crayfish, and also wanted our help to appeal so that everyone would stop eating crayfish. He said that most of the crayfish we eat now are grown in field trenches and feed on dirt and garbage. The meat contains a lot of heavy metals and even parasites.
Listening to this audience member, it is really creepy. Many people love to eat spicy crayfish, and in Guijie Street, Beijing, the spicy crayfish eaten there every day is named "tons" "To calculate. Think about it, on the one hand, it is a delicacy, but on the other hand, many experts and scholars have stood up against eating crayfish. So where does crayfish come from? Can crayfish be eaten? To this end, "Life" reporters conducted a special investigation.
The scientific name of crayfish is Crayfish crayfish. During World War II, it was introduced to my country from Japan. At present, crayfish in my country are mainly distributed in rivers, rivers and lakes in the middle and lower reaches of the Yangtze River, with a quantity of about 60,000 tons.
"Eight hundred miles of Dongting is picturesque." In recent years, the waters of Dongting Lake have become the main source of crayfish. It is also a typical representative of inland lakes, the main producing area of ??crayfish in my country. In order to investigate the growth environment of crayfish, we recently made a special trip to Dongting Lake.
1. What is the growth environment of crayfish? What kind of environment is most suitable for the growth of crayfish?
In the Yuanjiang section of West Dongting Lake, we found shrimp farmer Lao Gan. Lao Gan told us that every summer, crayfish will be active in the shallows. In winter or when crayfish shed their shells and reproduce, crayfish will lurk in caves to protect themselves. From June to August every year, crayfish are at their most plump, and this is also the best time for people to catch and enjoy them.
With green grass and shallow beaches, this water area is where Lao Gan and the others often fish for lobsters.
Shrimp farmers say that crayfish like to live in clean places, and in places like smelly ditches, crayfish do not grow very big.
Investigation shows: The rumor that crayfish grow better in dirtier places is unfounded.
2. Are most of the crayfish currently on the market artificially farmed?
Crayfish are omnivores and mainly eat animals. Small fish, shrimps, plankton, benthic organisms and algae can be used as its food. According to shrimp farmers, crayfish have a strong reproductive capacity and will ovulate two to three times a year. It usually only takes 2 months from the hatching of shrimp eggs to the maturity of crayfish.
The shrimp farmer said that he can catch up to three to four hundred kilograms per person at most, and there are probably thousands of shrimp farmers like him in the waters of Dongting Lake. Every day, about 30 tons of crayfish are shipped from Yuanjiang Market to all parts of the country.
Waters with shallow water plants are the favorites of crayfish, because this is not only a place for them to live, but also a hidden place for them to shed their shells. In addition, crayfish also like to drill holes, and their destructive capabilities are also very powerful. They often penetrate field ridges and destroy dikes. Combining these characteristics of crayfish, local shrimp farmers have specially made a shrimp fishing tool - the Earth Dragon King. The shrimp farmers set a mesh hole in each section of the Earth Dragon King, which is simple and convenient but can invite shrimps into the urn.
Shrimp farmers say there is no need for artificial breeding because the dragons...
