The GM Contamination Register database is run by Genewatch and Greenpeace and contains cases of genetically modified (GM) contamination dating from 1997. The authors of a 2014 paper, published in the International Journal of Food Contamination, analysed 400 or so cases in the database by crop and country.
GM rice accounted for about a third of contamination cases, despite the fact there is officially no GM rice grown anywhere in the world. They also focused on cases of contamination arising from unauthorised GM crops: those without any authorisation for commercial growing anywhere in the world. Nine cases were discovered of GM contamination of these unauthorised (non-commercialised) GM crops that haven’t undergone any environmental or food safety analysis. The authors argue that once GM contamination has happened, it can be difficult to contain.
Don Westfall, biotech industry consultant and vice-president of Promar International back in 2001, was at the time quoted by the Toronto Star (9 January 2001) as saying that the hope of the GM industry is that over time the market is so flooded with genetically modified organisms (GMOs) that there’s nothing you can do about it; you just sort of surrender.
It is not just a vague hope. It is an intentional strategy.
