Thank you very much, Mr. Chair.
I'd like to thank Gordon and Mark for being here. I'd also like to thank you for really focusing your comments on the supply chain. I thought that was really well done. We got a whole 10 minutes of different aspects of the supply chain, which is exactly what we're studying. That's much appreciated.
I wanted to ask a question about contamination of product, because in the supply chain a number of the processes you were talking about are common to all products. For example, when you look at trucks, railcars, elevators, conveyor belts, they're all moving different product. I know there's a concern between, for example, organic farmers and organic product, that it gets contaminated with non-organic product. Then, of course, there is the GM product as well, which would be separate from non-organic.
I'm wondering if you could talk to me or explain to the committee how that works, how is it that things can move through the system with, let's say, a low risk of contamination or cross-contamination, and, secondly, what you think the penalty might be on the system for whatever mechanisms you're going to tell us about. Is that a worthwhile price to pay, and is that where innovation can play a role? There are lots of questions there.
