Honey that contains traces of pollen from genetically modified crops needs special authorization before it can be sold in Europe, the European Union's top court said Tuesday, in a judgment that could have widespread consequences on the bloc's policy on genetically modified organisms, or GMOs.

The ruling from the European Court of Justice came after several Bavarian beekeepers demanded compensation from their government for honey and food supplements that contained traces of pollen from genetically modified maize.

The beekeepers had their hives close to fields where the Bavarian government was growing Monsanto's MON 810 maize for research purposes.

The EU has strict guidelines on authorizing and informing consumers about foods containing GMOs — a policy that has caused problems for producers of genetically modified seeds such as U.S.-based Monsanto Co. that are used to much laxer rules in other parts of the world.

Kelli Powers, a spokeswoman for Monsanto, said the company could not provide detailed comment on the ruling until the firm had a chance to read the entire judgment.

But Powers emphasized that the company's engineered corn seed has been approved as safe for human consumption.
