Animal rights group PETA on Friday called on race officials in New Jersey to cancel its Monmouth Park’s card on Saturday, amid an anticipated heat index of 110 degrees.

“Heat kills, so it’s extremely foolish and reckless for Monmouth Park to stay open with temperatures soaring to record highs,” PETA President Kathy Guillermo said in a statement.

The Oceanport racetrack will host its biggest race day of the year, including the internationally televised $1 million Haskell Invitational. Post time is 5:45 p.m.

Guillermo urged the racetrack and the New Jersey Racing Commission to postpone the event and cancel racing for the weekend.

“This is the only way to protect thoroughbreds from heat-related injuries, as New York, Maryland, and Pennsylvania tracks have already recognized,” she said. “If even one horse collapses, Monmouth officials should be held criminally liable for cruelty.”

Several thoroughbred tracks in the northeast, including Saratoga Race Course, have canceled their cards.

There is no racing at Belmont or Aqueduct racetracks — because both tracks are currently racing at Saratoga. Racing is scheduled at Yonkers Raceway and the Meadowlands Racetrack on Saturday.
