    This report is the first from the on-line GM Contamination Register ( and reviews cases reported in the public and scientific literature of contamination, illegal plantings and releases of GM organisms, and negative agricultural side-effects since GM crops were first grown commercially on a large scale in 1996. This represents a sample of the actual cases of GM contamination that have taken place, many of which are not detected or not revealed because they are part of food producers quality control systems. The report also includes a special review of the Syngenta Bt10 GM maize contamination incident that took place in 2005, affecting the USA, Europe and Japan and probably many other countries importing maize from the USA. It considers the scope and causes of all the incidents, to make recommendations for action.
