According to the European Regulations (EC) 1829/2003 and 1830/2003, products which are, consist of or contain GMOs should be labelled and traceable in each stage of production, processing and distribution.  Only in cases where the GMO level is below 0.9% and this presence is due to accidental contamination or is technically unavoidable, no labelling is required.  As it is very unclear how feed manufacturers have implemented these new regulations, a Belgian survey was held to evaluate the current situation at importer and feed production level.  Several bottlenecks were encountered, at the level of acquisition of raw materials and at production level, such as carry over of GM with non-GM soy in the production lines.  Next to this, some weaknesses in the analysis of GMOs were also revealed.
