| Genetically modified (GM) insecticidal rice line, Bt63 (Shanyou63), has been developed in China and found unauthorized in processed rice products in many countries. This transgenic rice contains a copy of the synthetic DNA sequence with two genes: CryIA(b) and CryIA(c). These genes encode for the respective Bt toxins which is lethal to Lepidoptera. The aim of this study was to determine the contamination of Bt63 in non-labelled commercially available processed rice products from supermarkets. In this study, a real-time Polymerase Chain Reaction (PCR) was used to simultaneously determine the contamination of Bt63. The survey was conducted on a total of 21 and 42 non-labeled samples of processed rice products collected in the years 2011 and 2012,... |
