Some vendors in Shanghai’s Jiangqiao Wholesale Market, the city’s largest, have been found selling winter bamboo shoots whitened with sulfur, despite sulfur being banned in fresh vegetables. A retailer called Shanghai TV saying bamboo shoots he bought from the market, which sells 20 to 30 tons of the produce a day to supermarkets and other retailers all over the city, had a strong smell of sulfur. Reporters who went to the market found some vendors admitting that the bamboo shoots were smoked with sulfur to give them a better appearance.
