Abstract

The regulation of labelling criterion for genetically modified (GM) foods has been enforced since 2001 in Korea. Therefore, GM soybean (GMS) or GM maize (GMM) processed foods must be labeled as GMO derived. We surveyed to see whether this regulation is kept relevantly or not and the distributive statue of GM processed foods. Using the method of polymerase chain reaction (PCR) based on endogenous gene (Le1n, SSIIb), promoter gene (P35S), terminator gene (NOS) and transgenic gene (RRS, Bt11, Bt176, GA21, T25, Mon810), we detected GMS and GMM processed foods circulating at the market in Busan area. Out of total 100 samples, 38 items were showed to be contaminated with recombinant gene by qualitative PCR. Among 82 domestic and 18 imported items, 32 (39.0%) and 6 (33.3%) items were detected with GM ingredients respectively. Also among the 80 soybean and 20 maize processed foods, 23 (28.7%) and 15 (75.0%) foods were sensitive to detect GMS and GMM ingredients respectively. For the qualitative PCR positive foods, we chased identity preservation (IP) certificates. And we verified that the PCR positive crops were grown up, harvested and shipped separately from GMO but just mixed with GMO in the threshold of the non attentional contamination levels (3%). Thus we can not find out any regulation-violent case at all. The results of this study will help to keep the regulations of GM labelling and be informative to consumers who want to know the laboratory results of GMO testing.
