Crayfish sales in Shenzhen are booming

After this newspaper reported that five citizens in Shenzhen suffered from rhabdomyolysis caused by eating crayfish, two 16-year-old girls in Guangzhou were suspected of being "hit" by eating crayfish yesterday. On August 10, the reporter visited the Futian Agricultural batch Market and found that although crayfish have been "causing trouble" frequently in recent days, citizens' enthusiasm for crayfish is still unabated, and sales are still hot.

Crayfish are still "favored" in the market

Yesterday, the reporter visited the Futian Agricultural batch Market and saw that many stalls in the fresh food trading area were filled with crayfish, and there was an endless stream of people buying crayfish, which did not seem to be affected by the frequent incidents of "crayfish allergy" in recent days.

"there are still a lot of people buying crayfish these days, and sales are no different from those before." A vendor busy carrying boxes of crayfish told reporters that their crayfish are usually purchased from Hubei, and some crayfish are from Hunan, with prices ranging from 28 yuan to 38 yuan per jin. As for the number of crayfish sold every day, many businesses say they sell too many crayfish every day to count.

Recently, members of the public have repeatedly suspected that rhabdomyolysis is caused by excessive consumption of crayfish. Is it because the crayfish is not clean? Another vendor picked up a crayfish and pointed to the crayfish's abdomen and said to the reporter: "Crayfish have sand from abdomen to head, because crayfish grow in the lake, it is inevitable that there is sand in the body." Therefore, it is safer for people to buy crayfish with a little sand, indicating that they have not been washed with shrimp powder. "

How to deal with sandy crayfish? 'just wash the crayfish with a basin of water, add some salt and white vinegar, rinse it with water twice, and the crayfish will be clean,'he said.

Most of the citizens randomly interviewed by reporters said they knew the news of "crayfish allergy" and would pay more attention to eating crayfish in the future, but many people said that they often ate crayfish and did not worry about allergies. A citizen bought 15 jin of crayfish on the spot. She said that if she bought it home, washed and cooked it, she would eat it more safely and relieved.

17 crayfish samples passed the sampling test.

Crayfish, whose scientific name is Kirschner's original shrimp, originated in America and was introduced into China in the 1930s. Crayfish meat taste delicious, and high protein content, low fat content, rich in calcium, phosphorus, iron, welcomed by the general public. As a result of repeated "crayfish allergy" incidents, crayfish were shot the most, so is crayfish safe after all?

According to Liu Xiayang, doctor of the Institute of Food and Drug Safety of Shenzhen Municipal Institute of Standards and Technology, crayfish is an aquatic food. inspection and implementation of the "hygienic standards for fresh and cold animal aquatic products", "limits for pollutants in food", "maximum residue limits for pesticides in food" and other national standards.

According to the 2015 Food Supervision and Inspection Information (No. 13) released by the Guangdong Food and Drug Administration, the Guangdong Food and Drug Administration sampled 17 crayfish samples (including crayfish and fresh crayfish) in Shenzhen. The results showed that no problems were found in lead, cadmium, methylmercury, inorganic arsenic, malachite green, chloramphenicol, nitrofuran metabolites (AMOZ, AOZ, AHD, SEM) and synthetic colorants in the samples, and all 17 samples were qualified.

Experts say there are many causes of rhabdomyolysis

Since crayfish sampling is qualified, how to explain rhabdomyolysis caused by eating? It is reported that rhabdomyolysis is a clinical disease caused by statins for the treatment of hyperlipidemia. Patients will have obvious systemic or local muscle pain reactions, increased hemoglobin, myoglobin and muscle enzymes, and no fever. Severe renal function can be severely impaired.

In fact, there are many causes of rhabdomyolysis syndrome. A study in the United States in 2000 showed that a variety of aquatic products may cause rhabdomyolysis, and some freshwater fish can also cause unknown rhabdomyolysis syndrome (also known as Haff's disease), which is seasonal and regional.

Dr. Liu Xiayang advises people who use statins to reduce blood lipids not to eat crayfish, which itself can directly cause rhabdomyolysis. In addition, crayfish is a high-purine food, so people with hyperuricemia and gout should not eat crayfish, regular consumption will aggravate the patient's condition.

Zhou Qidi, deputy director of the emergency department of Peking University Shenzhen Hospital, also reminded the public that most people will not experience rhabdomyolysis, but once they suffer from crayfish pain, fatigue, swelling, and soy sauce-colored urine, they need to see a doctor as soon as possible. More importantly, people with a history of rhabdomyolysis caused by eating aquatic products had better stop eating crayfish.
