Beijing should upgrade its testing methods for genetically modified organisms (GMOs) in food and review its labelling policy in the wake of growing consumer awareness, Greenpeace said yesterday. The group's China campaigner, Ma Tianjie, made the appeal ahead of today's World Consumer Rights Day, which this year has adopted the GMO theme. 'China still lags behind international standards when it comes to regulations related to GE [genetically engineered] food ... and the precision of the testing here is not good enough,' Mr Ma said. In a survey of 28 products collected randomly from supermarkets in Beijing, Shanghai and Guangzhou, the group found that Kraft's Ritz Crackers and Campbell's Golden Corn Soup with ingredients made from GE soybean were not labelled properly. Both companies have already pledged to avoid using GE ingredients in products sold in Europe. Kraft Foods and the Campbell Soup Company denied the accusations, saying they carefully followed regulations of different countries. Kraft's China director, Li Lingping , said: 'Decisions about whether or not to use biotech ingredients are made on a market-by-market basis after careful consideration of various factors, including consumer preferences, national regulations, labelling requirements and so on.' The Ministry of Agriculture, the architect of the mainland's GE food policy, only requires the labelling of GMO food products if they are made directly from transgenic crops - such as soya oil. Mr Ma expressed concern about testing capabilities, even if European standards were adopted. Greenpeace also said mainland consumers were more aware of the labelling issue. Among 600 residents surveyed in Beijing, Shanghai and Guangzhou, 62 per cent said they were aware of GE food and 57 per cent said they would choose non-GE food over modified food.
