I happen to have the Denmark map report for 2009. I'm reading right from the document, so this is the Danish experience. It says that for production animals in general, the consumption of antimicrobial agents has increased by 59% from 2000 to 2009, mainly because of an increase in consumption of antimicrobials in pork production.
That's the removal of the growth-promoters. It required that additional drugs be used to treat animals therapeutically, because they were getting sicknesses. It's a complex issue. By removing some of the products from production, you don't necessarily eliminate use—in fact you may increase it.
Time will tell, as Dr. Hansen was saying. Certainly the resistance in humans hasn't been affected in the Danish experience, from what I understand. Yes, there's been a reduction in the animal population, but one would expect that when the use has been reduced. But did it change in the human population? After all, that's what these bans have been about, to get outcomes relevant to the treatment of humans.
