As I said, there's also a public health issue. We've worked in Canada since 1923 to eradicate bovine TB from Canada because when we have to treat an animal or a human being with antibiotics it's a long treatment. Sometimes it could be six months to a year, with heavy doses of antibiotic. That's why we prefer to eradicate TB rather than treat it.
