Abstract:

 41 batches of soybean imported from the United States, Brazil, Canada and Argentina were tested with the event-specific detection method for 17 genetically modified (GM) soybean events. The analyzed results showed that: out of 17 GM soybean events, only 7 approved ones were detected in all 41 batches of imported soy⁃beans, namely MON89788, GTS40-3-2, MON87701, MON87708, A2704-12, A5547-127 and FG72, with detec⁃ tion rates of 90.24%, 87.80%, 43.90%, 41.46%, 36.59%, 17.07% and 2.44% respectively. In different batches of samples, different kind of GM soybean event were detected, among which, in samples of 6 batches, only 1 event was detected, but in samples of all batches, 2 to 5 kinds of GM soybean events could be detected. In samples from differ⁃ ent countries, the detected events were also different, including 7 from detected in American soybean, and 6, 5 and 3 from Brazil’s, Canada’s and Argentina’s soybean respectively. Even though different GM soybean events and contents were detected in samples from different countries, GTS-40-3-2 and MON89788 could be detected in soy⁃ beans from all 4 countries with high contents. These results could be useful for China to detect and identify import⁃ ed GM soybeans, and improve supervision of imported GM soybean.
