A woman in Wuhan City, Hubei Province, was diagnosed with rapid muscle breakdown after she ate crayfish, following an outbreak of 19 such cases in Nanjing City, Jiangsu Province, last week.
The 55-year-old woman surnamed Wang was sent to hospital at about 3am on Monday as she felt nausea and pain in muscles. She was diagnosed with rhabdomyolysis. She had also eaten crayfishes like the similar patients in Nanjing.
Wang said she and her husband ate a crayfish dish Sunday night in a restaurant. Her husband ate three crayfish while she herself ate more than 20. Her husband did not develop similar symptoms, Wuhan Evening News reported on Tuesday.
The city's food safety watchdogs told the newspaper that they did not receive any report about Wang's case. They also said there was no evidence to link the crayfish with the rare disease.
Media reported 19 people in Nanjing were suffering from rhabdomyolysis last week and linked a crayfish cleanser to the diseases, but Nanjing government said they were certain the washing powder, or oxalic acid, could not cause these symptoms.
China's disease control center has collected samples of Nanjing's crayfish for tests. But no results have yielded so far.
