Horse Health & Biosecurity Updates For Spring Series

Mar 14, 2022 | Announcements, Featured


Blenheim EquiSports (BES) is dedicated to the health, welfare, and safety of all equine and human exhibitors.

In support of the California State Veterinarian’s efforts to help stop the spread of EHM, we canceled the first week of our Spring Classic Series.

After consulting with USEF Chief Administrator for Drugs and Medications Dr. Stephen Schumacher, and a panel of leading equine veterinarians here in Southern California, we no longer require a PCR test for horses that are not affected by the USEF return-to-competition protocol.

USEF has implemented a return-to-competition protocol that applies to any horse that has been on the Desert International Horse Park (DIHP) or Rancho Murieta showgrounds, or any horse that has been exposed to a horse confirmed positive for EHV-1 off competition grounds in the past 14 days.

In order for an affected horse to return to USEF competition, the following requirements must be met:

  • Two negative PCR tests within 14 days, one at Day 7 and one at Day 14


  • One negative PCR test within 21 days, at Day 21


  • 28 days without a test, if the horse has been isolated for a minimum of 28 days

Affected horses must submit the USEF Return to Competition Declaration and USEF Competition EHV-1 Declaration Form to be released from the EHV-1 Ineligibility List and to return to competition.

In order to compete at Blenheim EquiSports competitions, the following ADDITIONAL REQUIREMENTS MUST be met:

  • Meet the minimum USEF criteria for affected horses, as outlined above;
  • Provide temperature readings for every horse for the three days leading up to the arrival at the showgrounds;
  • Submit the BES Horse Health Self-Certification Form for all horses competing at the event.

These documents must be submitted via the ONLINE FORM on the BES website (coming soon) to obtain clearance to compete.

Non-competing horses are not permitted on the showgrounds:
Horses that are not entered into the competition via ShowGroundsLive are not allowed to enter the facility.

No re-entry:
Horses may not leave the showgrounds and re-enter during the Spring Classic Series.

Schedule your move-in time:
To avoid overcrowding while horses are moving onto the showgrounds, we will provide assigned move-in times, as we do for the Las Vegas National Horse Show.

Move-in will begin on Sunday, April 3rd. The online calendar to schedule move-in times will be available soon.

Upon arrival at the Blenheim EquiSports showgrounds, we will require:

Horse vaccination records, including horse’s name, date of vaccine, and batch numbers, attested by your veterinarian. Please be sure that these documents accompany your horse and trailer.

Please make sure that the horse’s show name matches its vaccine records before entering the showgrounds as these documents will be checked prior to unloading any animal.

Immediately upon arrival, BES Management will supervise a temperature check performed by you or your staff.

Full Biosecurity and Horse Health Protocols are available online by clicking button, below.

Thank you for your patience and diligent attention in protecting the health of our equine partners.

We look forward to welcoming you back to the Rancho Mission Viejo Riding and sharing the exciting new improvements we have in store for the 2022 season.
