Producers urged to strengthen biosecurity as virus detected in Manitoba
A sow herd in southern Manitoba has recently tested positive for Seneca Valley Virus (SVV), a disease that continues to circulate at high-traffic livestock locations across Western Canada and the United States. This detection serves as an important reminder for producers to stay alert and maintain careful herd management practices.
Industry groups emphasize that SVV is still being found at assembly yards, abattoirs, and truck wash stations. These areas bring together many animals and vehicles, increasing the chances of spreading viruses if proper precautions are not taken. Producers are encouraged to strengthen their biosecurity routines at these sites to reduce the risk of contamination.
Early detection is especially important. Farmers should watch closely for symptoms such as blisters on a pig’s snout, mouth, or feet. These signs can look similar to other serious diseases, so reporting anything unusual to a herd veterinarian is strongly recommended. Proper diagnosis helps protect the entire swine sector by allowing experts to respond quickly.
While the virus has been known for several years, its transmission pathways are still not fully understood. Researchers believe both direct and indirect transmission may play a role, meaning the virus could spread through animal contact or contaminated equipment, footwear, or surfaces. Because the exact routes are unclear, extra caution is necessary.
There are currently no treatment options or vaccines available for Seneca Valley Virus. This makes prevention the most effective way to protect herds. Producers are encouraged to use available educational tools, including Manitoba Pork’s information sheet, which provides detailed knowledge about Seneca Virus A.
Several years ago, Alberta Pork developed a helpful series of farm biosecurity videos demonstrating how to safely move between clean and dirty zones inside barns. These resources guide producers on practical ways to keep disease out of their herds. They are great to share with team members as a reminder.
Overall, the recent Manitoba case highlights the importance of strong biosecurity, early reporting, and continuous awareness. By working together, producers can help protect swine health and maintain safe, healthy herds across the prairies.
