标题：Risk assessment of information on the subcombination Bt11 × MIR162, related to the application of Syngenta (EFSA‐GMO‐DE‐2009‐66) for authorisation of food and feed containing, consisting and produced from genetically modified maize Bt11 × MIR162 × MIR604 × GA21
摘要：Abstract The EFSA Panel on Genetically Modified Organisms ( GMO ) has previously assessed the single events Bt11, MIR 162, MIR 604 and GA 21 as well as different stacked events corresponding to combinations of these events. These maize events were found to be as safe as their conventional counterparts and other appropriate comparators with respect to potential effects on human and animal health and the environment. In its assessment of the four‐event maize stack Bt11 × MIR 162 × MIR 604 × GA 21, the GMO Panel also assessed all the subcombinations of these events not previously assessed, including some for which little or no experimental data were provided, including the two‐stack maize event Bt11 × MIR 162 (application EFSA ‐ GMO ‐ DE ‐2009‐66). On 8 November 2016, the European Commission received from Syngenta information on the subcombination Bt11 × MIR 162. On 14 December 2016, the European Commission tasked EFSA to analyse these data and to indicate whether they have an impact on the previously issued opinion on the four‐event stack Bt11 × MIR 162 × MIR 604 × GA 21 and its subcombinations. The GMO Panel used the appropriate principles described in its guidelines for the risk assessment of genetically modified ( GM ) plants to analyse the provided data. The levels of the newly expressed proteins Cry1Ab, PAT , Vip3Aa20 and PMI are similar between the two‐event stack Bt11 × MIR 162 and the corresponding single events Bt11 and MIR 162. Based on this analysis, there is no indication of an interaction between the events combined in maize Bt11 × MIR 162 that would affect the levels of the newly expressed proteins. Thus, the GMO Panel considers that the new information for maize Bt11 × MIR 162 does not alter the conclusions of the scientific opinion on application EFSA ‐ GMO ‐ DE ‐2009‐66.
