Thanks very much. I'll start and then I'm going to pass to my colleague Dr. James-Davies, who is involved with operations and can speak to the farm level.
You're correct that national biosecurity standards are voluntary. Biosecurity in general is a responsibility shared federally, provincially and territorially with industry associations and producers. The national biosecurity standards are the gold standard that has been produced through collaboration between the CFIA with industry, experts, provinces and territories. They establish a framework for biosecurity. Those standards—and there are eight of them—can be tailored and adopted and used by associations and producers to create their own biosecurity strategies. They have been adopted by several national associations to build into their mandatory on-farm safety programs. Examples are the Dairy Farmers of Canada, the Chicken Farmers of Canada and the Turkey Farmers of Canada.
With that, I'm going to pass it over to Dr. James-Davies to talk about the presence of the CFIA on farms.
