Poland will impose a complete ban on growing the MON810 genetically modified strain of maize made by US company Monsanto on its territory, Agriculture Minister Marek Sawicki said Wednesday.

"The decree is in the works. It introduces a complete ban on the MON810 strain of maize in Poland," Sawicki told reporters, adding that pollen of this strain could have a harmful effect on bees.

On March 9, seven European countries -- Belgium, Britain, Bulgaria, France, Germany, Ireland and Slovakia -- blocked a proposal by the Danish EU presidency to allow the cultivation of genetically-modified plants on the continent.

Seven days after that, France imposed a temporary ban on the MON810 strain.

Talks on allowing the growing of genetically-modified plants on EU soil are now deadlocked as no majority has emerged among the 27 member states.
