Twenty-one horses from a Venezuelan team competing at the US Open Polo Championship have died after collapsing before a match in Florida..
The International Polo Club of Palm Beach said the team was preparing its horses for an afternoon match when two collapsed and others began "exhibiting dizziness and disorientation."
The Florida Department of Agriculture says there's no obvious indication of the cause but the team's veterinarian James Belden says it's almost certainly something they ate
He says it's unlikely they died from tainted medication or had been given anabolic steroids because they are banned in England, where the team competes.
