Concerns raised over food quality

A man reads the ingredients on the label of a bottle of Shanxi vinegar (Shanxi Laochencu), which shows it contains the food additive sodium benzoate. Shanxi Vinegar Industry Association Vice-chairman Wang Jianzhong said that about 95 percent of Shanxi vinegar products in the domestic market are not genuine brewed concoctions. Soon afterward, he contradicted himself and denied what he said during an interview with the media. Liu Junfeng / for China Daily
