HALLANDALE BEACH, Fla. – The quarantine of Gulfstream Barn 3 will remain in effect until mid-March, even though there is no apparent danger to horses stabled there. Track officials said a horse who recently tested positive for equine infectious anemia, or swamp fever, has been shipped off the premises to a private farm in nearby Davie. All remaining horses have tested negative for the disease, but a 45-day quarantine is mandated by the Florida Department of Agriculture. According to Gulfstream, trainers with horses subject to the quarantine are Francisco D’Angelo, Troy Wismer, Bob Hess Jr., Jesus Lander, Milt Nunez, Angel Rodriguez, and Yvon Belsoeur. The quarantined horses are being allowed to train separately from the rest of the general population after regular hours conclude around 10 a.m. They also are allowed to race, but only in non-claiming events. “It’s an inconvenience, but not that big a deal,” said Hess, who has three horses in Barn 3 while the remainder of his stable is next door in Barn 4. “It’s just a matter of them taking every precaution they’re supposed to.”
