Monsanto Canada recently reported that the Canadian Food Inspection Agency (CFIA) has granted approval for its latest GM offering, the intriguingly named “refuge in a bag” Bt corn. With all the hype surrounding GM crops, it would be easy to dismiss this announcement as just another piece of press puff from the GM giant. But unfortunately this new development is actually something we need to keep a close eye on. As we have come to expect, the government has let the GM community police itself, leaving the companies that are peddling the new technology to regulate its use. First, it is important to understand what a “refuge” is when it comes to GM crops. Despite the fact that Animal Welfare Approved has blogged extensively on the many drawbacks and dangers of GM technology, the concept of “refuge” actually relates to a problem that we haven’t covered in detail before – namely the inevitable development of pest resistance to GM crops.
