I'll speak to the first part.
I think it's important to highlight that the investment in research and systems and technology has been integral to reducing food safety incidences. Between the years 2001 and 2009, our most current data, we know that E. coli incidences reported by people in Canada were reduced to less than half of what they were previously. We still have work to do and we don't like to see what happened, but, on the other hand, we are seeing that risk reduction, and we continue.
We also need to focus on the fact that food safety research has to transcend all areas. It's not just one thing. Moving forward, we see that investment in continued research, because we find that new things arise on an ongoing basis.
I'll let Martin speak to the second part, in terms of prevention.
