In recent weeks, pigs in the Midwest have been diagnosed with Seneca Valley Virus. This virus belongs to the genus Senecavirus within the family Picornaviridae.
It is important to remember not to take hogs with lesions or any of the clinical signs listed below to slaughter, unless a foreign animal disease investigation has been completed and the Board of Animal Health has been notified.
Clinical signs in infected sows, nursery pigs and finishing pigs may include:
- Vesicles and coalescing erosions on the snouts and coronary bands
- Acute lameness in a group of pigs
- Ulcerative lesions on or around the hoof wall
- Anorexia, lethargy and/or febrile; in the early course of the disease, fevers up to 105 degrees F have been reported
The Minnesota Board of Animal Health has put together a resource for how to manage movement to slaughter and the Seneca Valley Virus.
