The New Mexico Livestock Board and state Racing Commission are working with Sunland Park Racetrack to control a virus found in five horses.
They say the horse-specific virus was confirmed this week.
Several barns at the racetrack are under quarantine following confirmation of Equine Herpes Virus, specifically EHV-1.
The livestock board is taking extra precautions by restricting horse movement to and from the area that includes Sunland Park Racetrack as well as local horse-training centers Frontera, Jovi and Lazy S.
There are several strains of EHV. None of them are transmissible to humans.
The strain confirmed in the five horses is the neurotropic form of EHV-1, which can cause severe neurological problems.
