There are a couple of steps. In 2014, we eliminated any preventive use of category I antibiotics, most important to medicine. We made a decision in May of this year that by the end of 2018 we will eliminate category II, and our goal is to eliminate category III by the end of 2020. That's the process we're on.
We participate with CIPARS, under the Public Health Agency of Canada, and we do surveillance there on antimicrobial resistance. We also do it through our on-farm food safety auditing. We check usage and we check resistance in terms of tests they do on a randomized basis, and we compare the results of that with CIPARS.
