中國食品安全網訊  2021年7月7日，據歐盟食品安全局（EFSA）消息，應歐盟委員會的要求，歐盟食品安全局評估了2019年轉基因玉米MON 810上市后環境監測報告。

經過專家組評估，歐盟食品安全局發現，2019年轉基因玉米MON 810種植期間并未對人、動物和環境構成影響。部分原文報道如下：

Following a request from the European Commission, the EFSA assessed the 2019 post-market environmental monitoring (PMEM) report on the cultivation of Cry1Ab-expressing maize event MON?810. Like previous years, there was full compliance with refuge requirement in Portugal and partial compliance with refuge requirements by Spanish farmers growing MON?810 varieties. European and Mediterranean corn borer populations collected from north-eastern Spain during the 2019 maize growing season and tested for Cry1Ab susceptibility show no symptoms of resistance to maize MON?810. The assessment of farmer questionnaires and relevant scientific publications does not indicate any unanticipated adverse effects on human and animal health or the environment arising from the cultivation of maize MON?810. Overall, EFSA concludes that the evidence reported in the 2019 PMEM report does not invalidate previous EFSA evaluations on the safety of maize MON?810. However, as in previous years, EFSA identifies shortcomings on resistance monitoring that need revision in future reports. In particular, the monitoring plan, as implemented in 2019, is not sufficiently sensitive to detect the recommended 3% resistance allele frequency. Consequently, EFSA strongly recommends the consent holder to?achieve full compliance with refuge obligations in areas where adoption of maize MON?810 is high and?increase the sensitivity of the monitoring plan by performing periodic F2 screens on corn borer populations from north-eastern Spain. EFSA recommends revising the farmer questionnaires when new characteristics of the receiving environment emerge which are relevant for the environmental risk assessment of MON 810 such as the emergence of teosinte. EFSA encourages the Competent authorities of concerned EU Member States, the consent holder and environmental networks to engage in a dialogue to develop a framework on how to best identify and report unexpected adverse effects from the cultivation of Bt maize varieties.
