I'll start, and then the other guys can chip in.
I was on the committee that developed those guidelines, so I'm really familiar with them. One thing I will say is that when Mr. Leech gave his presentation and he mentioned the things the poultry industry is doing, I was ticking off the boxes mentally. They've basically implemented most—perhaps all, if we look at the fine print—of those recommendations.
I suspect that's not the case for all the animal commodities. We haven't yet completely stopped the use of growth promoters, and one of the major recommendations in the WHO guidelines is to stop that. But there is progress.
