BEIJING, April 12 (Xinhua) -- Food safety authorities in Qingdao, an open coastal city in eastern China's Shandong Province, have temporarily halted the sale of Chinese chives after seizing almost 2 tonnes of pesticide-tainted chives last week.
Nine residents have reportedly been poisoned after eating toxic chives this month. They have joined hands to ask for compensation from a local food vendor.
The patients complained of headache, nausea and diarrhea after consuming dishes that contained chives at a local fast food restaurant, Monday's China Daily quoted the local Qilu Evening News as saying.
All of them were poisoned by organic phosphorus, a highly toxic pesticide, officials from the Qingdao Health Supervision Bureau said.
"I bought a box of fried eggs with chives for 3 yuan (40 cents) last Wednesday. My husband had two bites and my child didn't eat any. I ate all of the rest," one of the patients, surnamed Yang, was quoted as saying.
She said the poisoning symptoms appeared 15 minutes after she had the dish.
"I was not thinking about the chives at all. Instead, I wondered if I was having some heart problems. I called my husband immediately," she said.
The other patients consumed the dishes at the same restaurant.
After recovering, the nine have filed a case with the local bureau of industry and commerce, demanding compensation.
Follow up inquiries revealed the tainted chives might not be just limited to one restaurant.
Random checkups on over 2,000 batches of chives, conducted from April 2 to April 9 in three vegetable wholesale markets in Qingdao, found 1,930 kg of chives contained excessive pesticide residue.
The tainted chives have been destroyed, the industry and commerce bureau told a local press conference late on Friday.
A pesticide residue rate as high as 64 percent was tested on the vegetables, and investigations traced the chives back to the city of Gaomi in Shandong Province, said Yue Hao, an official with the local industrial and commerce bureau.
A visit to the three vegetable wholesale markets over the weekend found dealers had stopped selling chives.Several randomly interviewed passers-by said they would not eat any chives for a while. Dealers said they had stopped selling the vegetable last Friday, citing a prohibition from the market authorities as the reason.
However, a manager surnamed Zhang from one of the markets said there was no such prohibition, but the dealers were not selling chives as a safety measure.
"The current supervision on chives is quite strict. A problematic sample will lead to major problems."
