Thank you for the question.
We have two programs. First, we have a passive monitoring program. When their productive life is over, dairy cows are sent to the abattoir.
We also have a post-mortem detection program. Since the frequency of infection cases is really very low, we don't want to do active monitoring. Moreover, since all of the milk in Canada is pasteurized, infections, should there be any, are eliminated. So the risks to human beings are non-existent.
