ALERT: Vesicular Stomatitis Confirmed in Texas and New Mexico
Below are the case details and new entry requirements for horses, cattle, sheep, goat and swine entering California from a VS Affected State.
Attached is the current VS Fact Sheet and additional information can be found at https://www.cdfa.ca.gov/ahfss/Animal_Health/VS.html .
On June 21, 2019, the National Veterinary Services Laboratories (NVSL) in Ames, Iowa, confirmed a finding of vesicular stomatitis virus (VSV) infection (Indiana serotype) on a premises in Kinney County, Texas. VSV-Indiana serotype has not been diagnosed in the U.S. since 1998; all VSV cases from 2004-2016 were VSV-New Jersey serotype. Horses on the index premises have met the case definition of infection with compatible clinical signs and virus isolation positive results. This is the 2019 VSV index case for the United States.
On June 24, 2019, the NVSL confirmed VSV infection (Indiana serotype) by polymerase chain reaction (PCR) in a lesioned horse on a second premises located in Tom Green County, Texas. This second affected premises is located nearly 200 miles due north of the index premises.
On June 26, 2019, the National Veterinary Services Laboratories (NVSL) in Ames, Iowa, confirmed a finding of vesicular stomatitis virus (VSV) infection (Indiana serotype) on a premises in Sandoval County, New Mexico. Two horses on the premises have met the case definition of infection with compatible clinical signs and positive complement fixation test (CFT) titers at a greater than 1:40 dilution, indicating recent infection. Both horses are also polymerase chain reaction (PCR)-positive for VSV (Indiana serotype) on swabs collected from the lesions. This is the 2019 VSV index case for New Mexico.
Vesicular Stomatitis Requirements for Importing Horses, Cattle, Sheep, Goats and Swine into California
All horses, cattle, sheep, goat and swine *originating from any state where vesicular stomatitis (VS) has been diagnosed (except cattle and swine transported directly to slaughter) must be accompanied by a health certificate (certificate of veterinary inspection) and signed by an accredited veterinarian that includes the following statement:
“I have examined all the animals identified on this certificate within 72 hours of shipment date and found them to be free from signs of Vesicular Stomatitis (VS). During the last thirty (30) days, these animals have not been exposed to VS nor located on a VS confirmed or a VS suspected premises.”
*For purposes of this requirement, “originating” means horses, cattle, sheep, goats, and swine that initially leave the VS infected state and come to California, or those that leave any state, visit an infected state, and then return to California.
The California Horse Racing Board (CHRB) has no additional requirements, at this time, on horses coming from a VS-infected area to enter race tracks and/or CHRB-approved training centers. For more information, contact CHRB at 916-263-6000.
