There are a number of different strategies. This is one that is quite innovative and very interesting. There are others in terms of using phages...the way you feed animals, in other words. If you change the percentage of feed, you can change the risk for those animals for E. coli and other infections. So there is a lot of very interesting research going on now. I'm not the expert to comment on which is best, but our scientists work with CFIA scientists and others in terms of what makes the most sense. As the consensus develops, then obviously those guidelines are shared.
