Also, the practical thing is that they're dealt with locally. But then we have systems in place to track, nationally and internationally, patterns of disease so that we can actually go back and see that there might be five cases in Vancouver and three in Saskatoon and four in Toronto, but they're all the same bug with the same genetic pattern. Then we can say what is in common. For example, perhaps there's a meat processor that distributes to only those three cities. So it really has to be a collaborative effort. And the same is true internationally in terms of how that's approached.
