Greece failed to make the ban Bt corn legal.

On 13 September 2007, Greece notified to the European Commission a ministerial decision concerning the extension of validity and amendment of an existing safeguard measure to provisionally prohibit the cultivation of the authorised genetically modified maize MON810 on its territory. The EFSA's Scientific Panel on Genetically Modified Organisms (GMO Panel) concludes that no specific scientific evidences, in terms of risk to human and animal health and the environment, were provided that would justify a prohibition of cultivation of maize MON810 authorised in Greece.
