Before 18 April 2004, GM material for feed use was not required to be labelled. Since then, labelling has been required for feed materials and compound feeds that contain GM or GM-derived material. Labelling is not required for feed consignments containing adventitious or technically unavoidable traces of GM, up to a threshold of 0.9% for GM varieties approved in the EU.
Until April 2007, there was a second threshold of 0.5% for varieties that had received a favourable scientific assessment but had yet to be authorised in the EU, but this was a temporary measure that expired in April 2007.
According to the European Feed Manufacturers' Association (FEFAC), at least 85% (about 107 million tonnes) of the EU's compound feed production is now labelled to indicate that it contains GM or GM-derived material.
