New Mexico reports more cases of vesicular stomatitis

To date, 11 New Mexico premises are under quarantine after vesicular stomatitis (VS) was detected last month in 2 Otero County horses. The counties of Otero, Valencia, Socorro and San Miguel have confirmed positive cases of VS, while Dona Ana and Roosevelt counties have suspect cases. The counties of Bernalillo and Santa Fe are considered high risk for cases of VS.

Based on these findings, New Mexico’s state veterinarian says a health certificate (CVI) will be required for all New Mexico-origin livestock in locations where out-of-state livestock are a part of a public event such as roping, racing, breeding or other forms of public exhibition, or traveling interstate.

The certificate must be written within 5 days of entering the show and must contain the following statement:

“The animals represented on this certificate have not originated from a premises or area under quarantine for Vesicular Stomatitis (VS), or a premises on which VS has been diagnosed in the past 21 days. I have examined these animals and have not observed lesions or clinical signs of VS”.

The Texas Animal Health Commission (TAHC) prohibits entry of animals from VS-quarantined premises into Texas and requires other livestock to be accompanied by a valid certificate of veterinary inspection.

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 will usually heal in 2 to 3 weeks. Because the signs of VS mimic those of foot-and-mouth disease (FMD), animal health officials strongly urge livestock owners and caretakers to report potential cases of VS to their private veterinary practitioner or state livestock health officials.

TAHC officials encourage livestock owners to use the best means possible to limit exposure of livestock to insect bites. It is theorized that insects are involved the transmission of VS.
