genetically modified foods be labelled in the market place

The guideline is proposed to apply to labelling of foods and food ingredients in three situations, when they are:

(1) significantly different from conventional counterparts
(2) composed of or contain GM/GE organisms or contain protein or DNA resulting from gene technology
(3) when they are produced from but do not contain GM/GE organisms, protein or DNA from gene technology.
