***UPDATE***
As of 11:30 a.m. on Friday, Nov. 21, 2025, we have made changes to the required CVI statement for horses:
“The equine listed on this CVI have, during the 21 days prior to the shipment date, not originated from a premises under EHV-1 quarantine, not been exposed to an EHV-1 positive equine, and not attended any event where an EHV-1 positive equine has been confirmed.”
This change is to provide more clarity around the horses being brought into Oklahoma and for the Oklahoma horses going to upcoming equine events. Oklahoma horse owners should check with event staff before traveling to see if the event has extra requirements for entry.
***********************************************************
Following the recent increase in EHV cases, ODAFF is implementing a required statement to be listed on all equine CVIs for interstate movement into Oklahoma through Jan. 1, 2026.
At this time, we are not implementing any requirements for intrastate movement for horses.
For questions about the new requirement, please contact the Oklahoma State Veterinarian at 405.522.6141
