Assessment of the 2021 post-market environmental monitoring report on the cultivation of genetically modified maize MON 810 in the EU.

ABSTRACT: Following a request from the European Commission, the European Food Safety Authority (EFSA) assessed the 2021 post-market environmental monitoring (PMEM) report on the cultivation of Cry1Ab-expressing maize event MON 810. Evidence provided in the PMEM report shows that farmers growing maize MON 810 in Spain complied partially with refuge requirements, while full compliance was achieved in Portugal. Cry1Ab susceptibility tests performed on European and Mediterranean corn borer populations collected from north-eastern Spain in 2021 indicated no symptoms of resistance evolution to maize MON 810. However, unexpected damage to maize MON 810 plants was observed in a field trial in the province of Girona (north-eastern Spain), which may point to the presence of resistance alleles in this region.
