The State Veterinarians’ Office issued a directive on Friday night, January 20, that horses in the affected barn are quarantined and security is in place to only allow access by essential personnel.  Results of testing are expected to be available Monday evening, January 23.  The Office will develop schedules to allow eligible horses in the barn to work on the track outside normal training hours after all other horses have returned to their barns.

Outbreak Update
No neurologic symptoms consistent with EHM have been observed since the clinical horse was isolated from Barn 36.
