In March 2010, the European Commission approved BASF’s genetically modified Amflora potato for cultivation in the European Union. CEO has investigated the background to this decision, including the controversial scientific advice provided by the European Food Safety Authority on the use of antibiotic resistant marker genes. CEO found that more than half of EFSA’s GMO panel had conflicts of interest, as defined by the OECD. Their advice, which contravened WHO guidelines, contributed to the approval of the GM potato - and is likely to lead to the approval of similar GM crops in the near future.
