Recently, a netizen posted that after eating crayfish in Yaohan, Pudong, Shanghai, all three people in the same trade had symptoms such as diarrhea, vomiting and muscle aches all over the body, and were diagnosed with rhabdomyolysis after admission. According to the hospital, three people had rhabdomyolysis syndrome at the same time. According to the description before seeing a doctor, it can basically be judged that it is caused by food, but it is not clear what factors lead to rhabdomyolysis in the process of making, storing and cooking crayfish.

On August 14, the Market Supervision Administration of Pudong New Area released a relevant survey, saying that after investigation, the JASON ZHANG store of "Shanghai Xiaopang" (Shanghai Xinzhi Catering Co., Ltd.) held a valid food business license, and all employees held health certificates. On July 30th, Store * * * bought 447 Jin of crayfish and sold about 200 Jin of crayfish that day. Only the store can provide suppliers' qualifications, purchase vouchers, quick test reports of wholesale market testing centers and other related materials. No abnormality was found during the on-site inspection.

According to the investigation, at present, the Market Supervision Administration is urging the store to actively communicate and coordinate with the complainant on this matter, and the two sides are still in the process of negotiation.

According to experts, generally speaking, muscle lysis is mainly caused by muscle injury caused by extrusion, trauma, strenuous exercise and other factors. Some viruses, lipid-lowering drugs, β2 receptor agonists, amphetamine, drugs and other drugs that damage muscles can also dissolve muscles.

Because the cell membrane is destroyed, the contents of muscle cells are released into the blood, and these contents contain a lot of myoglobin. Because myoglobin needs to be excreted through the kidney, and myoglobin itself is a "big guy", it is easy to block renal tubules and affect renal function. Mild symptoms can lead to hemoglobinuria, and severe symptoms can also cause acute renal failure. For patients with myoglobinemia, doctors will treat them with alkalized urine and give infusion to make them drink more water to help myoglobin excrete. Some kidney damage that is not particularly serious can also be reversed.
