That's a great question.
I think we're making substantive changes already through the suite of regulatory changes and the policy changes, which will place a veterinarian in the decision-making process for medically important antimicrobials, which will avoid the use of these important antimicrobials for the promotion of growth, for which there is no modern scientific evidence that it is effective to do so. This is good.
In terms of the amount of antimicrobials, as I said in my introductory remarks, more than 70% of medically important antimicrobials are used in animals.
There are some very good reasons for that. Number one, animals are much bigger than we are. A 600-kilogram cow, and there are many of them in this country.... When we look at the amount that is used, we need to remember those two key important facts.
