The European Environment Agency (EEA) looked at six crop types to see how much cross-pollination occurs with neighboring crops or wild relatives and concluded oilseed rape, sugar beet and maize -- three key GM crops -- had a medium or high likelihood of transferring genetic material to organic or wild plants, and so posed a risk to organic farms certified as GM-free

This report, written for the EEA by experts from the European Science Foundation, considers the significance of the transfer by pollen of genes from six major genetically modified (GM) crop types that are close to commercial release in the European Union. Oilseed rape, sugar beet, potatoes, maize, wheat and barley are reviewed in detail using recent and current research findings to assess their potential environmental and agronomic impacts. The report also includes a short review of the current status of GM fruit crops in Europe.
