THE discovery of a BSE-infected cow in Canada confirms warnings from European scientists three years ago that cattle in North America could be infected. And if Canadian cattle are infected it is likely that the disease is also present in the US.

The US and Canada test so few animals that low levels of BSE infection would not be detected. Indeed, the number Canada tests would be unlikely to reveal a level of infection any lower than what the UK now has. Other countries have found many more cases after increasing testing when the first infected cattle were reported.
