the presence of illegal genetically modified ( gm ) material in seeds is unavoidable, an European Union ( eu ) scientific committee has stated. The Scientific Committee on Plants ( scp ) in its report Opinion of the Scientific Committee on Plants concerning the adventitious presence of gm seeds in conventional seeds also says that the eu may have to revise its upper limit for the compulsory labelling of food that may unintentionally contain gm material. In 1999, the European Commission ( ec ) had ruled that all food products sold in the eu must be labelled as containing gm material if one of their ingredients contained at least one per cent dna or protein of gm material. The ec is reviewing the recommendations of the committee.
