We have carried out a critical examination of the alleged new data on a potential environmental impact of these varieties, namely two scientific papers describing laboratory force-feeding trials on ladybirds and daphnia, and previous data on Lepidoptera, aquatic and soil organisms. We demonstrate that the suspension is based on an incomplete list of references, ignores the widely admitted case-by-case approach, and confuses potential hazard and proven risk in the scientific procedure of risk assessment. Furthermore, we did not find any justification for this suspension in our extensive survey oTransgenic research1-12https://www.ebi.ac.uk/biostudies/studies/S-EPMC2801845biostudies-literatureIs the German suspension of MON810 maize cultivation scientifically justified?PMC2801845Kuntz MRicroch ABerge JBfalseIs the German suspension of MON810 maize cultivation scientifically justified?We examined the justifications invoked by the German government in April 2009 to suspend the cultivation of the genetically modified maize varieties containing the Bt insect-resistance trait MON810.
