Three racehorses died last week at Belmont Park on the track’s first week of racing for their fall meet.

Last Friday, which was opening day at the Long Island track, saw two deaths, according to online data provided by the New York Gaming Association.

One of the horses, Passporttovictory, was injured in the third race and removed from the track by an ambulance. The thoroughbred was later euthanized.

The other opening-day incident happened during training when Royal Inheritance “collapsed and died” on the grounds of Belmont Park, according to NYGA.

A day later, another horse went down while training. No Moxie was “spooked and flipped while jogging” and had to be put down, NYGA records show.

The deaths at Belmont Park represented three of six equine fatalities at New York racetracks this month, according to the state data.

Two horses died at Saratoga Racetrack — one on Labor Day and another last Saturday.

Last Tuesday, a horse died at Finger Lakes racetrack.

The New York Racing Association, which operates three tracks across the state — including Belmont and Saratoga — is reviewing each incident, a spokesperson told LoHud.

“As the process moves forward, NYRA continues to advance measures to ensure we are providing the safest possible environment for training and racing at Saratoga Race Course, Belmont Park and Aqueduct Racetrack,” spokesman Patrick McKenna told the paper.

“The health and welfare of horses and jockeys competing at NYRA tracks is our highest priority and one that stands above all other considerations.”
