Every crop is different, so there's a different potential with each crop.
Before genetically engineered crop were introduced in Canada, we had no discussion as to the potential for contamination. We're having that discussion now, and it's better late than never. Zero tolerance is the international standard. It's the policy reality in Canada and in other countries, in our export markets. The question really needs to be asked what zero tolerance means. For health and safety it might be necessary. In terms of some crops, also, it's unavoidable. For example, you would have to make sure that there's no Roundup Ready alfalfa on the market if you're to ensure there's no contamination. We know this is the case for some crops.
There may be the ability to manage contamination in some crops, and that's what the threshold level proposes. The LLP policy recognizes contamination as a problem and actually proposes looking at the biology of crops and what the industry can manage in terms of contamination. That's a discussion we should have had 20 years ago. But I think zero tolerance is what is expected right now from many consumers, certainly.
