In the United States, we have also looked at legislation. For 40 years they have been looking at having the industries voluntarily change what they have been doing. That hasn't worked especially well, because there still is an awful lot of it that's used, even excluding the ionophores, which has been talked about, which is an antibiotic not used in humans. But even excepting that, there are an awful lot of antibiotics used for healthy animals.
In the United States we're contemplating—our Food and Drug Administration, which would be similar to Health Canada's VVD—disallowing that approval that they approved, similar to what they did here. They approved that back in the 1950s and 1960s, when we thought we were going to have a new drug every week. Our FDA is looking at changing its guidelines and we're also looking at a legislative fix so that antibiotics can be used for sick animals, if they are prescribed by a veterinarian, or for animals that have been exposed to disease, but not for healthy animals.
