The harm of eating crayfish
1, rhabdomyolysis
Crayfish has paragonimiasis, which is easy to cause rhabdomyolysis. Generally speaking, crayfish and crabs all carry paragonimiasis, and roasting, frying and pickling can't guarantee to kill the larvae of paragonimiasis. So eat crayfish must be cooked. Street barbecues, food stalls and beer squares are becoming more and more popular in summer, so we should pay attention to distinguish the true and false meat quality when eating barbecue. Eat cold dishes in moderation. Afraid of unsanitary stomach upset.
2, crayfish cooking time is too short to cause poisoning.
You must pay attention to food hygiene when eating crayfish. If the cooking time is short and the bacteria are not completely killed, it is very likely to cause food poisoning. Due to the large market demand, crayfish are basically purchased from other places, and then transported for a long distance in the high temperature climate in summer. There are not a few dead crayfish, and some restaurants even sell them after frying. Because crayfish contains a lot of histidine, once crayfish dies, histidine will be converted into toxic substances. Although a small amount of food will not cause poisoning immediately, it will cause diseases due to the accumulation of toxins. In addition, crayfish is the second intermediate host of paragonimiasis. If cooking is not thoroughly cooked, or cooked in the form of roasting, frying, salt and drunkenness, people may be infected with paragonimiasis after eating. Experts also reminded that if the tail of crayfish is not curled and the meat is loose when eating crayfish, it may be dead lobster, so don't eat it. In addition, the number of crayfish eaten at one time should not be too large.
Expansion: What troubles will lobsters bring?
Skin allergy: Lobster is a high protein food. Excessive intake of protein will lead to heterogeneous protein reaction, which may cause systemic allergy and red rubella mass.
Acute gastroenteritis: eating unclean or undercooked lobster is easy to get acute gastroenteritis.
There are many kinds of parasites in the neck and head of lobsters, so it is forbidden to eat them raw, which can lead to paragonimiasis in severe cases.
Gout: Don't drink beer when eating lobster, because lobster has high protein and high purine content. If you eat lobster and drink a lot of beer at the same time, it may cause an increase in blood uric acid and cause gout attacks.
Extension: Is the harm of crayfish a rumor?
There have been many hospitalizations in Nanjing because of rhabdomyolysis. Epidemiologists highly suspect that crayfish is the chief culprit in analyzing patients' dining history.
However, experts conducted various tests and analyses on the collected crayfish samples, including pathogenic bacteria, heavy metals, pesticide residues, antibiotic residues, hormones, parasites, algal toxins and so on. No abnormalities or substances that may cause rhabdomyolysis were found. Finally, this incident was characterized as "Huff's disease".
Huff's disease is a rhabdomyolysis with unknown causes, which occasionally occurs in all countries in the world, usually within 24 hours after eating this product, but there is no obvious regularity. In addition to eating crayfish, there have also been cases similar to eating marine fish and freshwater fish.
There is also a saying on the Internet that "washing shrimp powder" causes rhabdomyolysis. In fact, the main component of washed shrimp powder is oxalic acid, which has no possibility of causing rhabdomyolysis in mechanism. Although it is really acidic, it is water-soluble and has to go through many processing procedures after washing, so it is impossible to have a high concentration on shrimp. Many vegetables we usually eat are also rich in oxalic acid, such as spinach.
Of course, crayfish may indeed carry parasites, but this is not its patent. Other aquatic organisms can also be carried, such as frogs, snails, shellfish, fish, water chestnuts and so on. The key to prevent parasitic diseases is thorough cooking. 100 degree cooking 10 minutes or more is safer, especially don't eat raw or undercooked crayfish.
Extension: Can crayfish be poisoned by heavy metals if they eat too much?
"Crayfish live in polluted water, eat garbage and are rich in heavy metals, which is extremely harmful to human body." Are these all true? Crayfish can really adapt to all kinds of polluted environments, but that doesn't mean they like to stay in dirty places. In fact, crayfish can "carry" down, thanks to its good detoxification mechanism. In the process of metabolism, crayfish can gather and transfer heavy metals to the shell, and then transfer toxins out of the body by constantly molting.
This energy-consuming process makes crayfish not grow much meat, and it is difficult to store energy for reproduction. In fact, they like clean water and fresh food best, so that they will be big and reproduce. The crayfish on the market are basically big and fleshy. Moreover, the domestic crayfish has a large export volume and can pass the food inspection abroad.
So, don't worry about heavy metals. Many rumors about crayfish have also been refuted by many responsible researchers.
