Toxin killed 21 polo horses, vets say

WELLINGTON, Fla. — Ladies in their spring dresses and men in casual linen suits sipped champagne and nibbled hors d’oeuvres as they waited for the U.S. Open polo match. What they ended up with was a field of death.

Magnificent polo ponies, each valued at up to $200,000, stumbled from their trailers Sunday and crumpled one by one onto the green grass. Vets ran out and poured water over the feverish, splayed-out animals. But it was no use. One dead horse. Then another. Then more. And within a day, 21 horses were dead.

State veterinarians were still performing necropsies but suspect the horses died from heart failure brought on by some sort of toxic reaction in their bodies. Possibly tainted feed, vitamins or supplements. Maybe a combination of the three.

Polo club officials and several independent veterinarians insisted the deaths appeared to be accidental.

Some horses died on scene. Others were shuttled to clinics for treatment, but there was nothing that could be done. Their fate was sealed.

All the dead horses were from the Venezuelan-owned team Lechuza Polo, a favorite to win the title at what’s described as the World Series of this sport. The team included about 40 thoroughbreds in all, maybe more.

Dr. Scott Swerdlin, a veterinarian at Palm Beach Equine Clinic near the polo grounds, treated one of the sick horses. He said it appeared the animals died of heart failure caused by some kind of toxin that could have been in tainted food, vitamins or supplements.

“A combination of something with an error in something that was given to these horses caused this toxic reaction,” Swerdlin said Monday.
