Li Zhen reports on shoppers ’ reactions in Shanghai. An investigation by the municipal government revealed that Shanghai Shenglu pany produced more than 3,000 steamed buns daily. These were then sold across the city, including large supermarkets such as Hualian, Lianhua and Dia. Fewer steamed buns were for sale at this Lianhua Supermarket. More than 32,000 buns were taken off store shelves when the scandal emerged. Mr. Wang, Sales Manager of Lianhua Supermarket, said, “ We removed the dyed steamed buns produced by Shenglu as soon as we learned of the incident. We gave customers who had bought the steamed buns from our outlets refunds with their receipts. Despite the scandal, our sales volume has been fine so far. ” However, most customers we met remained concerned about food safety. Steamed buns are a regular breakfast food for Ms. Gao. She used to buy them mostly from supermarkets because she felt it was ina clean and safe en viro nment. But now, she has second thoughts about buying the popular snack. Ms. Gao, Shanghai shopper, said, “I can ’t believe that even steamed buns from the supermarkets are no longer safe. The only places I trusted to shop at were major supermarkets and specialist shops.
