GRAND ISLAND, Neb. (AP) — Racing restrictions that were briefly placed on about 25 horses at a second Fonner Park barn in Grand Island have been lifted.

The Nebraska Department of Agriculture had announced the restrictions Friday afternoon after a horse in the barn exhibited signs of equine herpes. On Saturday, those restrictions were lifted after test results showed the horse did not have the illness.

The racing venue is under quarantine after three other horses there tested positive for equine herpes. One horse was euthanized; the other two are being treated.

The 750 to 850 horses at Fonner Park can’t leave until the minimum 21-day quarantine is lifted. Fonner will continue racing through May 7, but the horses in the barn where the sick horses were kept are currently banned from racing.
