Vesicular Stomatitis detected in Texas cattle
Vesicular Stomatitis (VS) has been detected in two head of cattle in South Texas, 5.7 miles southwest of Mathis (Jim Wells County). According to the Texas Animal Health Commission, the cattle were tested after the owner observed blistering and swelling on the animals’ muzzles and contacted their local veterinary practitioner. Testing at the U.S. Department of Agriculture Foreign Animal Disease Diagnostic Laboratory at Plum Island, N.Y., confirmed the virus as the New Jersey serotype, which is the same serotype found in previously reported cases in Texas horses.
VS can cause blisters and sores in the mouth and on the tongue, muzzle, teats, or hooves of horses, cattle, swine, sheep, goats, llamas, and a number of other animals. Lesions usually will heal in two or three weeks. Because of the contagious nature of VS and its resemblance to other diseases such as foot and mouth disease, animal-health officials urge livestock owners and caretakers to report these symptoms to their veterinarian immediately.
The newly identified infected herd of cattle is currently under quarantine by the state commission. Regulatory veterinarians will monitor affected and exposed cattle until all lesions have healed and a decision is made to release the quarantine (a minimum of 21 days). There is no known exposure to other cattle. This is the first case of VS in cattle in the United States since 2006.
The disease may be spread by direct contact with infected animals or by biting insects. The disease is rarely fatal.
“Livestock owners should try to limit exposure of their animals to biting flies,” said Dr. Dee Ellis, the Texas state veterinarian. “Sand flies and black flies play a role in the virus transmission, so controlling insects is important.”
“If you suspect your animal may have VS, you should notify your veterinarian immediately,” said Dr. Andy Schwartz, Texas state epidemiologist. “VS is not highly contagious to people, but it can cause flu-like illness if infected saliva gets into an open wound, eyes, or mouth. People handling potentially infected animals should wear gloves for protection, and talk with their physician if they have questions.”
Some states, including Louisiana, and other countries may restrict movement of or impose additional requirements for, susceptible animals from states and counties having known cases of VS. See “Louisiana VS requirements” for more information. Animal-health officials in the intended state of destination should be contacted prior to movement.
For information about these movement restrictions, contact the state or country of destination.
