First of all, it's not a feasible thing to have a universal protocol because bacteria and their resistance differ internationally. There's certainly a hope that eventually we'll have an acceptable standard policy for what settings they can be used in so that they should only be used for humans or animals that have documented infection, or where the use of antibiotics for prevention is of benefit, and that they should be prescribed by a health care professional. I think, as a starting point, we need to get to that stage because you can go to the market in some developing countries and just choose by colour, shape, and size which antibiotics you want.
It's important to Canadians that we advocate for wise use across the country. For most of the drug-resistant infections that we have in Canada, the strains originated elsewhere, but some did not. We even have some strains that we're proud to call Canadian, but many have come from elsewhere as well.
