Through the chair, yes. As Mr. Perron just mentioned, there was one recently in Saint-Hyacinthe, Quebec, where some protestors came on a hog farm, and now that hog farm is infested with rotavirus, something they haven't seen in more than 40 years. We've now seen that coronavirus can be passed from person to mink. There have been mink farms whose herds have been euthanized.
To your question, Mr. MacGregor, it only takes one. We are still recovering from bovine spongiform encephalopathy in our cattle industry. There was one case on one ranch in Alberta. We still have not recovered from that incident, and that was more than 20 years ago. We lost more than 3,000 ranches in Canada as a result of that one case of BSE. Only this past summer did Canada apply for negligible risk status on BSE. That cost this industry tens of billions of dollars in lost cattle but also lost export markets. We are still just getting back into South Korea and Japan.
There have been cases where this has been identified as an issue, but, I mean, it only takes one. Imagine the impact on our pork industry if we had a case of African swine fever. It would devastate this industry in Canada, as we've seen in nations like China. They've had to euthanize more than one million animals.
