I think it's a very good start. In the United States those are just guidelines, and the industry has had similar guidelines and has had, as you said, judicious-use guidelines for 30 to 40 years. We don't think we've seen a change in the amount of antibiotic that's used.
I would also like to respond with regard to the amount of antibiotics sold in the United States for food animals versus what's sold in the United States for human use. Three-quarters of the antibiotics are used both in humans and in animals. Three-quarters of those antibiotics are used in food animals. If you add the ionophores, which keep coming up, because they're not a drug for humans, then that figure for the United States goes up to over 80%, and that isn't tracked here in Canada.
