The New Mexico Livestock Board is relaxing the
movement and health care restrictions on all
counties in New Mexico except Los Alamos and Taos
There are ongoing investigations and Quarantines in
Los Alamos and Taos
Counties. Movement restrictions and Five Day
Certificates of Veterinary Inspection for events in
these counties or livestock traveling out of these
counties will remain in effect.
Persons with livestock traveling out of state from
Los Alamos and Taos counties must obtain permission
from state of destination prior to movement.
Canada and other states may continue restrictions on
New Mexico Livestock movement for an indefinite
period of time. All New Mexico producers and
veterinarians must contact state of destination
prior to movement.
New Mexico is continuing to experience positive cases of
Vesicular Stomatitis (VS). This disease is classified as a
Foreign Animal Disease and therefore requires case reporting
both nationally and internationally.
Currently eleven premises are under quarantine. The counties of
Otero, Valencia, Socorro and San Miguel have positive
confirmed cases. The counties of Dona Ana and Roosevelt have
had suspect cases. The counties of Bernalillo and Santa Fe are
considered high risk for cases of VS.
Based on the current understanding of the disease and
consultation with USDA researchers knowledgeable of the
pathogenesis of this virus, New Mexico can expect to experience
continued cases in livestock throughout the summer and fall
The disease Vesicular Stomatitis can be expected to occur
primarily but not limited to, areas along rivers, streams,
irrigated pastures and lakes or other bodies of standing water.
While most cases are reported in horses this virus readily
infects all species of livestock. The disease has been shown to
be transmitted by a number of biting insects, ‘no- seeums’,
midges or other biting insects. Animals primarily affected are
those in living in pastures . The particular strain currently
circulating does not appear to have been in New Mexico
The last significant out break of VS was in 2005. We therefore
have a large susceptible population of livestock, and reports
are this virus strain is causing significant lesions in
affected animals. This current virus appears to be more
virulent than previous outbreaks. Several animals have
experienced severe lesions and in some cases significant
supportive care has been required for infected animals.
Vesicular Stomatitis is considered mildly zoonotic and in rare
cases can be transmitted to humans. Precautions are indicated
when handling suspect livestock.
Dr. Paul Ettestad , NM Dept of Health has suggested the
In people, vesicular stomatitis is uncommon, but can cause an
acute illness that resembles influenza. The incubation period
is usually three to four days, but it can be as short as 24
hours or as long as six days. The symptoms may include fever,
muscle aches, headache and malaise. Vesicles are rare, but can
occasionally be found on the mouth, lips or hands. Most people
recover without complications in four to seven days. Humans can
become infected when handling affected animals, contaminated
fomites, tissues, blood or virus cultures. To prevent
infection, protective clothing and gloves should be used when
handling infected animals.
The livestock community is urged to closely follow the below
1. All livestock producers in New Mexico are
cautioned to keep close observation of their livestock.
Excessive drooling, lip and oral ulcers , blisters or vesicles
in the lip area, loss of epithelial tissue in the oral cavity
are primary signs of this disease. Where the disease is
suspected producers need to contact their veterinarian
2. Event organizers are asked to work closely
with a veterinarian to be sure all livestock entering public
events are free of the disease. The finding of a positive
animal at an event requires immediate quarantine of all
livestock attending the event. The objective is to limit the
disease to infected premises and not increase exposure by
moving infected livestock.
3. Where out of state livestock are a part of the event
a Health certificate (CVI) written within five days of entering
the show will be required for all New Mexico origin livestock.
The following statement is to appear on the CVI: “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.”
