[img_assist|nid=21|title=|desc=|link=none|align=right|width=150|height=65]Since their introduction in 1996, GM crops have contaminated food, feed, seed and the environment right across the globe. Over 60 have been documented in 27 countries on 5 continents. In June 2005, GeneWatch and Greenpeace launched the GM Contamination Registerto record them.
It includes all known incidents of contamination arising from the intentional or accidental release of GMOs. as well as illegal plantings of GM crops and the negative agricultural side-effects that have been reported. There may however be others that are, as yet, undetected.
The latest incidents in this list is New Zealand's investigation into GM contamination of maize which concludes that this was caused by imported GM soybean, residues of which were left in the storage facilities also used for the maize.
