Following a request from the European Commission, the Panel on Genetically Modified Organisms of the European Food Safety Authority (EFSA GMO Panel) compiled its previous risk assessment conclusions and risk management recommendations on the genetically modified insect resistant maize 1507, and considered their validity in the light of new relevant scientific publications published from 2005 onwards.
The EFSA GMO Panel performed a search of the scientific literature to identify new scientific publications specific to maize 1507 that may report new information relevant for the risk assessment and/or management of maize 1507. Subsequently, the EFSA GMO Panel evaluated whether the information reported in recent publications, identified by the literature search, would invalidate its previous risk assessment conclusions on maize 1507, as well as its previous recommendations on risk mitigation measures and monitoring.
Following a search of the scientific literature published between 2005 and September 2012, the EFSA GMO Panel identified 61 peer-reviewed publications containing evidence specific to the risk assessment and/or management of maize 1507, of which 25 publications were discussed and cited in previous EFSA GMO Panel scientific outputs. From the remaining 36 publications, two were relevant for the food and feed safety assessment of maize 1507, and 34 for the environmental risk assessment and/or risk management of maize 1507.
The EFSA GMO Panel did not identify new peer-reviewed scientific publications reporting new information that would invalidate its previous conclusions on the safety of maize 1507. Therefore, the EFSA GMO Panel considers that its previous risk assessment conclusions on maize 1507, as well as its previous recommendations for risk mitigation measures and monitoring, remain valid and applicable.
When defining measures to delay resistance evolution to the Cry1F protein from maize 1507 in target insect pests, risk managers should consider that Cry1Ab-expressing maize events (such as MON 810) are approved for cultivation in the EU. The EFSA GMO Panel recommends that, in regions where maize 1507 and Cry1Ab-expressing maize events would be cultivated together, refuge areas equivalent to 20% of the total Lepidoptera-active Bt-maize area are established due to the potential for cross-resistance between Cry1Ab and Cry1F.
