Calder Casino & Race Course said on the afternoon of March 22 that it is lifting a ban on horses shipping into and out of its property, effective 12:00 a.m. the morning of March 23. However, Calder is maintaining indefinitely a quarantine on the barn that was the stable for a horse that became ill on March 20 and died on the morning of March 22.

The Miami Gardens, Fla., track made those decisions after test results showed the horse had not been suffering from equine herpesvirus type -1 (EHV-1), said track spokeswoman Michele Blanco.

A laboratory at the University of Kentucky made that determination after testing blood samples from the horse that were sent by Calder.

Until further notice, horses in the quarantined barn will be permitted to train only during periods separate from Calder’s regular training hours. No other Calder barns and horses are under restrictions
