For the hog industry, I want to make sure that everybody understands how major a risk biosecurity is for us. For anybody here who doesn't know, there was the PED virus outbreak in the U.S. in 2014, where they managed to kill some 7 million baby pigs. This bug is so virulent that our vet described it as being able to take one thimbleful of this virus, diluting it in an Olympic-sized swimming pool, and having enough virus to kill the entire Canadian hog herd. This is how virulent this is.
If you talk to Canadian hog producers about going to a public area and unloading pigs with a bunch of other pigs whose history they don't know, or cattle trucks that might have come back up from the U.S. packing a PED virus in a cattle liner, they will tell you unequivocally, it won't happen. They will not put their animals at that risk.
What would it look like? Imagine some sort of a NASA biocontainment facility with eight million different roads, so you never had to travel on the same road as the truck before you. It sounds like a ridiculous thing, but honestly that's what you would be talking about if you wanted to go to something close to zero risk. That's why we don't do it.
