The European Commission has outlined draft legislative measures for dealing with the adventitious presence of GM seeds in conventional varieties. According to the working paper, GM material that is covered by the EU directive 90/220, which regulates the deliberate release of GMOs into the environment, should not exceed a threshold of 0.3% in the case of cross pollinating varieties and 0.5% in the case of self pollinating and vegetatively propagating crops. (There is zero threshold for GM seeds not authorized under 90/220.) In addition, the Commission wants longer time periods between the planting of non-GM crops on land previously sown with GM plant varieties—two years instead of one for most plants, but five years in the case of plants whose seeds would survive several years (such as fodder plants, and oil and fiber plants). The document also proposes labeling requirements: all packages of seeds must carry “EU-unauthorized genetically modified organisms not present” on the label, and packages of seeds of GM varieties authorized under 90/220 are to be labeled “genetically modified variety.” The deadline for government comments on the proposals is April 10.
