2021年7月7日，据欧盟食品安全局（EFSA）消息，应欧盟委员会的要求，欧盟食品安全局评估了2019年转基因玉米MON 810上市后环境监测报告。
经过专家组评估，欧盟食品安全局发现，2019年转基因玉米MON 810种植期间并未对人、动物和环境构成影响。部分原文报道如下：
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.
