Vesicular Stomatitis in New Mexico
RELEASE DATE: June 5, 2012
A new case of Vesicular Stomatitis has been identified near the town of Peralta in Valencia County. Additional cases of VS can be expected throughout the coming months. The counties of Socorro, Bernalillo, and Santa Fe can be considered high risk for the occurrence of Vesicular Stomatitis at this time. Livestock owners are encouraged to use the best means possible to limit exposure of their livestock to insect bites. It is believed that insects are an important vector in the transmission of VS. Vesicular Stomatits causes blister-like lesions to form in the mouth and on the dental pad, tongue, lips, nostrils, hooves, and teats. These blisters swell and break, leaving raw tissue that is so painful that infected generally refuse to eat or drink and show signs of lameness. Severe weight loss generally follows, and in dairy cows, a severe drop in milk production commonly occurs. Affected dairy cattle can appear to be normal and will continue to eat about half of their feed intake.
Why is this important?
While vesicular stomatitis can cause economic losses to livestock producers, it is a particularly significant disease because its outward signs are similar to (although generally less severe than) those of foot-and-mouth disease, a foreign animal disease of cloven-hooved animals that was eradicated from the United States in 1929. The clinical signs of vesicular stomatitis are also similar to those swine vesicular disease, another foreign animal disease. The only way to tell these diseases apart is through laboratory tests.
South Carolina Import Restrictions for VS (R27-1013E)
Wild and domesticated hooved animals, including but not limited to bovine, equine, porcine, ovine, caprine, and cervidae, are prohibited entry into South Carolina if they have been exposed to Vesicular Stomatitis within thirty(30) days immediately preceding their entry in South Carolina, or if they originated from an area within ten(10) miles of a premise where VS has been diagnosed in the thirty(30) days immediately preceding entry into South Carolina. All animals described above which originate in a state in which VS has been diagnosed must have the following statement written by the accredited veterinarian issuing the CVI:
"All animals identified on the certificate have been examined and found to be free of VS. During the past thirty(30) days, these animals have not been exposed to VS nor located within ten(10) miles of an area where VS has been diagnosed."
