Florida's state Veterinarian, Dr. Thomas Holt, said test results showed that a selenium overdose was the likely cause of death of the 21 polo horses that died prior to a polo competition in Wellington, Florida on April 19. Dr. Holt stated the animals had "significantly increased selenium levels."
Selenium is a trace mineral essential for normal cell function and health in animals and is typically included in small quantities in supplements and feed for horses. But, in a large dose can be fatal for animals.
The University of Florida, the University of California, Davis and Cornell University conducted tests on the horses to determine the exact cause of death.
A further investigation continues into the death of the 21 horses.
