New buffer strip guidelines for EU GM maize
Isolation distances of 15-50 m are the best way to reduce cross-pollination between genetically modified and non-GM maize, and to limit GMO content in conventional food and feed to levels below 0.9%. Distances of 105-500 m should be used if the aim is to reduce admixture levels to 0.1%. The recommendations come in a new best practice document prepared by the European Coexistence Bureau (ECoB) and published by the European Commission’s Joint Research Centre. In addition to the spatial isolation, specific measures to ensure adequate seed storage should be used to limit or avoid comingling, it concludes.
