  • Fair Grounds Barn Under Quarantine
    TDN Tuesday, December 27, 2016
    Barn 14 at the Fair Grounds has been placed under quarantine by the State of Louisiana’s Department of Agriculture after a horse residing in the barn tested positive for a strain of Equine Herpes Virus known as EHV-1. The infected horse, an unraced 2-year-old filly trained by Alice Cohn, was euthanized Monday.
    Horses currently stabled in Barn 14 will not be permitted to leave the property until the quarantine has been lifted and will only be permitted to train during a specific period after regular training hours. All residents of Barn 14 will continue to be monitored and is none show signs of or test positive for the virus, the quarantine will be lifted at the end of the standard 14-day period.
    The quarantine will not affect horses shipping in for races as long as they have the proper vaccination documents.

  • Quarantine Has Gun Runner's Pegasus Hopes in Jeopardy
    By Alicia Wincze-Hughes, The Blood-Horse January 3 2017
    The good news for fans of grade I winner Gun Runner is that the son of Candy Ride is officially targeting the $12 million Pegasus World Cup Invitational (G1), Winchell Thoroughbreds manager David Fiske confirmed Jan. 3
    From articla
    Since his breakout victory over older foes in the Nov. 25 Clark Handicap (G1) at Churchill Downs, Gun Runner has been at Fair Grounds Race Course & Slots with trainer Steve Asmussen's string preparing for his 4-year-old debut. With the entire Fair Grounds backstretch currently under quarantine due to an EHV-1 outbreak, no horses are permitted to ship in or out of the track—an issue that could complicate both potential deals with shareholders to get Gun Runner into the Pegasus and his ability to arrive in South Florida in time for the race.

    Very contagious! I wonder if they have identified contact points or sources?

    Articles have 3 types in them
    1 a strain of Equine Herpes Virus known as EHV-1. (neurogenic I think)
    2 a positive result for the “wild strain.”
    3 the non-neurogenic type of EHV-1
    So far, I haven't read the contact point or source.
    As a stable and horse owner, you must be very concerned.
    I built the Discussion going back just a over a month. This shows how fast
    the virus can spread.

    No cases in MD.

    That is Good News!

    Evidently, horses who have been affected, but cured, can still shed the virus for life, although I don't know about all types. Quick read of some vet studies. Can cause neurological damage and abortion in pregnant mares. K

    Let me clarify those EHV1 testing costs
    1st round per horse @$180
    2nd round per house @$122
    Pretty pricey stuff
  • Thanks for starting this discussion Keta. EHV-1 isn't something to take lightly at all.

    New Protocols, More Tests: Fair Grounds EHV-1 Outbreak ‘At Least A 45-Day Process’
    by Chelsea Hackbarth The Paulick Report .| 01.13.2017
    As the first group of barns at the Fair Grounds Race Course near the end of their state-mandated equine herpesvirus quarantines, the Louisiana Department of Agriculture has been working to define the procedures which will allow those barns to be released from quarantine. Following a meeting earlier in the week between horsemen, USDA representatives, veterinarians, and outside advisors, those protocols have nearly been finalized.
    According to assistant state veterinarian Dr. Dianne Stacey, any barn that has held a horse which tested positive for EHV-1, whether it be the wild strain or the neurogenic strain, is automatically quarantined for a period of 14 days. The horse which demonstrated the positive test is placed in isolated quarantine for 21 days; those with the wild strain are kept separate from those with the neurogenic strain.
    In order to get out of quarantine, all the horses in the affected barn have to demonstrate two negative EHV-1 tests, spaced at least 72 hours apart, as well as undergo final checks by state veterinarians
  • Finally some good news about the EHV-1 outbreak in Louisiana! Fair Grounds: No further horses test positive for equine herpesvirus:
  • No new positives or movement on quarantine at Fair Grounds:
  • Five test positive at Kentucky training center for less-virulent form of herpes:
