The recent announcement that the production of genetically modifed canola will be permitted suggests that the long controversy over the GM issue is drawing to a close, with a reasonable chance of an outcome that should be satisfactory to most.
GM foods can be produced and sold in Australia, but, in general, must be labelled as such. Producers and consumers can decide to avoid GM if they want to, but those who are willing to embrace GM will not be prevented from doing so. There’s a problem here in relation to canola, since it’s mostly processed into oil for use in margarine and other products and this isn’t covered by the current labelling requirements – this should be fixed.
The policy decision reflects a pretty clear scientific consensus that the products in question are safe to consume, and also a long period of experimental work with genetic modification. With a few exceptions (notably those driven by Monsanto in the US), this work has been carried out with admirable caution, beginning with the Asilomar conference in 1975, which may be seen as the first application of the precautionary principle. Given the experience of the past thirty years, and the scientific understanding that has developed over that time, it seems pretty clear that any risks associated with GM are modest and manageable, not the potential catastrophes that worried the participants at Asilomar.
