Thank you for the question.
Mr. Chairman, the vaccine is subject to the regulatory oversight of the CFIA. Before the vaccine can be marketed, the CFIA assesses both its effectiveness as well as the safety of the vaccine for the target animals. In this case, the product was assessed, demonstrated to be effective in reducing the shedding of E. coli, and therefore was approved. It provides to the producer one more option in terms of effective stewardship.
You have heard Dr. Evans on a number of occasions speak to the importance of a whole-chain approach to food safety. Food safety starts right on the farm, in terms of the stewardship of the producer, in terms of their animals, and in the feeds the animals have access to. It's the on-farm food safety practices that reduce the potential for the animal to have chemical residues or to be shedding pathogens that might ultimately contaminate the meat. In the case of this particular vaccine, it provides one more opportunity for the producer to have an option in terms of that effective stewardship.
