🚨 Vesicular Stomatitis Virus (VSV) Update: What NY Horse Owners Should Know 🚨
There was a recent case of Vesicular Stomatitis Virus (VSV) reported in Arizona. The NY State Department of Agriculture and Markets has issued a warning to veterinarians practicing in our state and we'd like to remind everyone just how relevant this outbreak is even if AZ seems quite far away!
🐴 VSV is a viral disease that affects all hooved animals, including horses, cattle, and pigs. It causes painful blisters around the mouth, nose, sheath, belly, and udder, and sometimes at the coronet band (where the hoof meets the leg). While most animals recover, the lesions make it hard to eat and drink, leading to weight loss and secondary infections.
⚠️ Why it matters:
1️⃣ The symptoms of VSV look identical to Foot and Mouth Disease, a major international trade concern. Only lab testing can tell them apart.
2️⃣ Even mild cases can cause significant discomfort and productivity loss.
📋 New York State Restrictions:
To prevent spread, NYS has strict import rules for animals from affected regions:
-No equines or other hooved livestock may enter NY from within 10 miles of a confirmed VSV case in the past 30 days.
-Animals from affected states must have a Certificate of Veterinary Inspection (CVI) that includes a VSV-free statement from the examining veterinarian.
✈️ Planning to ship or winter your horse back here from out west?
Check for VSV updates before booking travel and make sure your paperwork meets New York’s entry requirements.
If you have any questions about infectious diseases, how they could affect your horse, and what protective measures you can take, check in with your veterinarian at your next appointment or give us a call to schedule.
