That's a fantastic question. If we had the answer, we would already know where to focus. This is why it makes it complicated, but interesting, from an academic point of view. This is why Canada and all the other countries also have used this multi-sectoral approach, because if you only focus on prescribing in hospital, it won't work. If you're only taking an agricultural stand, it won't work. There's also the environmental dimension. I don't want to frighten anybody, but they took 10 samples of soil close to sewers in the region of Toronto and out of those 10 samples, seven had some of the bacteria that were highly resistant to the best antibiotics. That doesn't mean it will transfer from the environment to humans, but we have to be aware that they exist already in Canada.
I realize that I'm not really answering your question here, but on the other hand, I think it's really a multi-sector approach that is needed. Maybe some of my colleagues would like to complement this answer.
