Before I answer that, if I could just go back to Monsieur Malo's questions a little bit and just point out that, in terms of concrete evidence linking declines in bacterial resistance in humans and better policy, you don't have to look any further than a study last year from Quebec, which Dr. Hansen referred to. After producers voluntarily stopped using ceftiofur for a few months, there was a dramatic decline in ceftiofur resistance in both food and in people. When they started to use it again, resistance started to increase. Interestingly, as Canadians and talking about this here, one of the smoking-gun studies now referenced on the international stage is the Canadian study, which I hope the committee would take a look at.
I just wanted to add that, before perhaps Dr. Hansen answers.
