I apologize if I appeared to disagree with Dr. Hansen.
The EU model has been successful for the countries in the European Union, but we have had very different legislation on veterinary antimicrobials in our country, in North America, dating way back to the 1970s. It's not as if you can cut and paste the legislation that they have. We have a completely different system.
The reason we appear to disagree is that antimicrobial resistance is an extremely complex issue. We're talking about multiple commodities; and within each commodity, multiple bacteria species; and within each of those bacteria species, multiple resistance concerns driven by multiple drugs. It's easy to get lost in the details and draw on something that's a success, or dismiss something else as a failure.
Overall, it's a flawed experiment because there's no control to the situation. We don't know where the situation would have been without the withdrawal of the growth-promoting drugs, and we haven't done a very good job of measuring the farm-level drug use and correlating that all the way through to the clinical instance of disease in people.
