Our main concern there is if people use food scraps. I guess if the meat is from Canada, then the food scraps are not of much concern because we don't have the disease yet. The issue is if one family receives a visitor bringing some contaminated pork product carrying the virus from one of those infected countries. It just takes one event to bring a disaster. It would go in the food scraps of those pigs.
