The Minnesota Board of Animal Health and the University of Minnesota Veterinary Diagnostic Laboratory have noticed an increase in swine vesicular cases at Minnesota farms and slaughter plants.
While these cases have been found to be associated with Senecavirus A (SVA), the general symptoms cannot be distinguished from those of certain foreign animal diseases, including foot and mouth disease and other swine vesicular diseases.
MBAH officials ask that farmers be vigilant for clinical signs of SVA and to contact them if they see any of the following signs:
- Vesicles, blisters, or healing blisters on the snout or around the snout
- Blisters or sloughing of hooves (pigs may appear lame)
To report clinical signs, please call the Minnesota Board of Animal Health at 651-296-2942 or contact your local state or federal animal health official.
Contact information and a MBAH field staff map are both available online.
To reduce the risk of the disease spreading when SVA symptoms are present, MBAH recommends producers:
- Do not move the affected animal(s).
- Isolate sick animals from healthy animals, if possible.
- Document movements leading up to the onset of symptoms.
- Contact your veterinarian.
- Cooperate with the state or federal animal health official collecting and submitting samples as part of the FAD investigation.
