Comments: The New York Department of Ag & Markets, The New York Racing Association, Inc. (NYRA) and the New York State Gaming Commission (NYSGC) have placed Barn 85 at Saratoga Race Course under a 14-day official quarantine due to a positive case of strangles in that barn. Barn 85 contains horses trained by Jeremiah Englehart and Jorge Abreu. The index case, a 2-year-old Thoroughbred colt, trained by Englehart, was shipped to Rood & Riddle Equine Hospital on Wednesday, May 28, 2025 for evaluation and treatment of a respiratory infection. On Thursday, May 29, 2025 the positive test results were reported. The colt began treatment immediately at Rood & Riddle and transported from the hospital to a private layup facility. Following official notification of the positive case by the NYS Department of Agriculture on Friday morning, NYRA and the NYSGC implemented standard infectious disease protocols including restricting access to the horses in the quarantined barn, establishing a 24-hour security watch, mandating regular temperature checks for the horses in that barn and enacting biosecurity measures for all individuals requiring access to Barn 85. Overseen by Dr. Sarah Hinchliffe, the director of NYRA's veterinary department, in consultation with the NYSGC, and the NY Dept of Ag & Markets, Barn 85 quarantine is effective immediately. Abreu has horses in both Barn 85 and Barn 86, and only the horses in Barn 85 are quarantined. The Abreu horses located in Barn 86 can train and race with the general population. The horses under quarantine will not be permitted to enter races or train among the general horse population. Afebrile/asymptomatic horses stabled in Barn 85 will have isolated training hours at the Oklahoma Training Track following the close of training for the general horse population at 10 a.m. For information about strangles visit: https://www.equinediseasecc.org/strangles;
