Following a request of the European Commission, the European Food Safety Authority’s Panel on Genetically Modified Organisms (EFSA GMO Panel) evaluated the documentation submitted by Luxembourg in support of its request for the prohibition of the placing on the market of the genetically modified maize MON 810 according to Article 34 of Regulation (EC) No 1829/2003. All concerns related to human and animal health or the environment raised by Luxembourg were already addressed in previous scientific opinions of the EFSA GMO Panel on maize MON 810 while other concerns relate to socio-economic aspects and co-existence and thus fall outside the remit of EFSA. Therefore, the EFSA GMO Panel concludes that, based on the documentation submitted by Luxembourg, there is no specific scientific evidence, in terms of risk to human and animal health or the environment, that would support the notification of an emergency measure under Article 34 of Regulation (EC) No 1829/2003 and that would invalidate its previous risk assessments of maize MON 810.
