What we did was the trailers, and this only applies to trailers that go to farms in the United States. Trailers that go to slaughtering plants only have to be scraped. They don't have to be cleaned and disinfected, but it has to be a good scraping job. Most commercial operations wash them when they come back to Manitoba anyway. For the ones that go to the farms, we decided that the U.S. was not going to do any regulation. We've talked to the state veterinarians. They're not going to do anything about it, and that's just their approach on things. They have a different way of managing disease in the United States than we do.
Our issue is that we don't want these diseases coming into our herds, because it hurts our productivity per sow, which is our competitive advantage over the United States. Iowa has the lowest cost production system in the world, with 45 million pigs—more than Canada's total production—in one state alone. We send baby pigs there because they import 30 million into that one state alone. We are directly integrated in that, so we have to have some sort of control over what comes back across the border.
Ontario does the same thing. It ships finished pigs into the United States for slaughter, and it also sends baby pigs into the United States.
