A turbot fish that was found to contain exce ive amounts of carcinoge 

The government Tuesday moved to allay public fears after a series of food-safety scares, the latest of which centred on turbot fish that was found to contain exce ive amounts of carcinoge .

Many major ci ties including Beijing have ba ed the sales of turbot in markets and restaurants after Shanghai a ounced over the weekend that it had detected exce ive residues of nitrofuran and chloromycetin in 30 samples of turbot. The fish are believed to have been shi ed from Shandong Province.

Some farmers reportedly fed the fish with large quantities of medicinal su lements, which leave harmful, cancer-causing residues, to increase their disease resistance.

The Ministry of Commerce said yesterday that it was drafting a regulation to standardize food safety procedures under which markets need to keep a record of the su ly chain and ban unregistered su liers.

The Ministry of Agriculture and the State Food and Drug Administration (SFDA) have set up a team to investigate the source of contaminated turbot in Shandong. The SFDA has also ordered local offices in such areas as Jiangsu, Hebei, Zhejiang, Fujian, Guangdong, Liaoning, and Tianjin to closely monitor the situation.

In Shandong, where the a ual turbot output is estimated at about 45,000 to  worth 3 billion yuan (US$375 million), an official surnamed Fu told China Daily: "We are tracing the source of the fish and will a ounce the result in a week."

The turbot is a flat fish typically served at banquets and u cale restaurants and is popular with both Chinese and foreigners. A serving costs between 70 yuan (US$8.75) and 150 yuan (US$18.75) per 500 grams.

Last week, more than 5,000 ducks were culled in Hebei after it was found that farmers fed them cancer-causing dye Sudan Red IV to make the egg yolk a sought-after red.
