Elsewhere across the Southwest, vesicular stomatitis, or VS, has recently been detected in two horses in New Mexico. The U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS) confirmed the infection of two horses in Otero County, according to TAHC. The horses were sampled after vesicular lesions were observed on both animals.

Officials say early reports indicated five horses were thought to be infected with VS, and all of them remain under quarantine. No new cases of vesicular stomatitis have been identified elsewhere in the state. A New Mexico state veterinarian inspected all livestock within a one mile radius of the infected equine. In all there were 128 horses and 24 head of cattle examined.

According to a New Mexico state veterinarian, based on the current findings of vesicular stomatitis in the area, “all livestock leaving Otero County will be required to have an inspection by a veterinarian within 7 days of transport if they are traveling to a public event such as roping, racing, breeding or other forms of public exhibition or traveling interstate.”

The Texas Animal Health Commission prohibits entry of animals from VS quarantined premises, and also requires 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 other animals. Lesions usually will heal in two or three 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 inspector.
