UF pathologists, researchers play key role in determining cause of death

of polo ponies

P ostmortem testing conducted by University of Florida College of Veterinary Medicine
pathologists and toxicologists on a group of prized polo horses that collapsed and
died April 19 in Wellington, Fla., drew international attention, with riveted members of
the public and the press wanting answers about the mysterious cause of death.
Blood and tissue samples were gathered from 15 horses on which UF pathologists
conducted necropsies. Six other horses had been sent to the Florida Department of Agriculture
and Consumer Services' diagnostic laboratory in Kissimmee, Fla., for postmortem
examinations. The necropsies of all 21 horses yielded no answers, nor did subsequent
microscopic examinations. Even the UF Racing Laboratory, which routinely conducts
toxicology screening tests of race horses in the state, revealed nothing initially that could
explain the horses' sudden deaths.
Subsequent tests conducted by UF toxicologist David Barber, however, verified the
presence of life-threatening concentrations of selenium in the horses' blood and liver. The
concentrations were found to be 10 to 15 times higher than normal in the blood and 15 to 20
times higher than normal in the liver.
"Our role in testing was key, not only because we were able to verify the toxic levels of
selenium found to be present in the blood and liver of these horses, but also because through
additional testing conducted at our Racing Lab, we were able to rule out the presence of
common performance-enhancing drugs," said Dr. John Harvey, the college's executive
associate dean and a board-certified clinical pathologist.
"This is significant, because in ruling out other drugs that could have killed these
horses, we essentially were able to corroborate the assessment that indeed these deaths were
likely caused by an accidental overdose rather than due to malicious or criminal intent."
The 15 horses UF performed necropsies on arrived around 3 a.m. on Monday morning,
April 20. The first group of six horses had been taken to the state diagnostic laboratory in
Kissimmee, Fla., filling it to capacity.
An eight-person UF pathology team led by Dr. Lisa Farina and Dr. Jeff Abbott, both
board-certified anatomic pathologists, immediately set to work conducting the necropsies of
eight of the 15 horses. The task was completed at approximately 5 p.m. on Monday. Soon after,
a request came to necropsy the remaining seven horses All of the necropsies, including those
performed at UF and those conducted at the state's diagnostic lab, were complete by day's end
on Tuesday.
Wednesday morning, Farina and her colleague, Dr. Michael Dark, an assistant professor
of anatomic pathology, began examining slides with tissue samples under the microscope
while a CNN reporter videotaped them at work.
By this time, reports had surfaced that individuals associated with the polo team had
admitted giving vitamin supplement shots to the horses shortly before they died. Speculation
intensified as to what exactly had been administered and whether any of the ingredients in the
supplement injections could have caused the horses' deaths.
Meanwhile, blood samples taken from some horses before they died had arrived at UF
and were being tested at the UF Racing Lab, under the direction of Dr. Richard Sams.
Pathologists and toxicologists remained puzzled, as nothing conclusive had yet emerged.
On Thursday, April 22, the focus of the story took a dramatic shift when a spokesperson
for a private pharmacy said that the horses had received an incorrect dose of one of the
ingredients used in a vitamin compound with which the horses had been injected. Because of
ongoing law-enforcement and other investigations, the pharmacy did not initially release the
name of the specific ingredient.
Based on this information, Dr. David Barber, an associate professor in the Center for
Environmental and Human Toxicology in the college's department of physiological sciences,
worked until late Thursday night conducting analysis of inorganic components of the vitamin
Testing was performed on the blood and livers of affected and unaffected horses and
while Barber was not informed which horse was the "control" horse, he guessed the obvious
after completing the testing. The unaffected horse was the only horse among those tested that
showed normal levels of selenium in its blood, as compared to very elevated levels detected in
the blood of other horses tested. A pharmacy spokesperson later confirmed that selenium was
the mistaken ingredient.

selenium in the blood and livers of several of the horses that died suddenly in Wellington just prior to a
tournament on April 19. Selenium was determined to be the probable cause of death. The UF College of
Veterinary Medicine Racing Lab meanwhile had performed screening tests on samples from the animals in order
to rule out the presence of any performance-enhancing drugs in the horses' systems. (Photo by Sarah Carey)

Dr. Jerome Modell

Two small animal veterinary practice owners from Gainesville and Miami, the chief
veterinarian at the Georgia Aquarium and two UF professors emeritus have been
honored for their career accomplishments by the UF College of Veterinary Medicine.
Four awards were given through the 2009 Distinguished Award program, which is
sponsored by the college's alumni council and offers recognition to deserving alumni, faculty
and others who have contributed meaningfully to UF and/or to the veterinary profession.
Dale Kaplan-Stein, D.VM., and Julio Ibanez, D.VM. both received Alumni Achievement
Awards this year.
Kaplan-Stein, a member of the college's class of 1981, owns Oaks Veterinary Hospital
and Northwood Oaks Veterinary Hospital, both in Gainesville. She also helped establish
Affiliated Pet Emergency Services in
Gainesville in 1988. For more than 20 years,
Kaplan-Stein has been a tireless volunteer for
Gainesville Pet Rescue, Alachua County
Animal Services and No More Homeless Pets,
among other groups. In 2007, she founded
the St. Francis House Pet Care Clinic, through
which she has helped provide care to nearly
500 pets of homeless and disadvantaged
people living in the Alachua County area.
Ibanez, a member of the college's
charter class of 1980, owns Quail Roost
Animal Hospital in Miami. He is a former
president of the college's alumni council and
has been actively involved in the Florida
Dr. Tonya Clauss Veterinary Medical Association. He also has
served on the executive boards of the South
Florida Veterinary Medical Association and
the South Florida Veterinary Foundation. Ibanez received the FVMA's Gold Star Award in 2003
for his outstanding contributions to veterinary medicine.
The Outstanding Young Alumnus Award was given to Tonya Clauss, D.VM. Clauss, a
2003 graduate of the UF veterinary college, is chief veterinarian at the Georgia Aquarium,
where she works with one of the world's largest collections of aquatic animals. Frequently
featured in the national news whenever the Aquarium treats high-profile cases, Clauss is an
active spokeswoman for the importance of aquatic animal health.
Louis Archbald, D.VM., Ph.D., a professor emeritus of animal reproduction, has
received the Distinguished Service Award. Archbald joined UF's faculty as a professor and
assistant dean for clinical services/chief of staff of UF's Veterinary Medical Teaching Hospital
in 1984. Until he retired in 2008, Archbald directed minority-oriented initiatives, later known
as multicultural and special programs at the college. He received the 2001 Iverson Bell Award
from the American Association of Veterinary Medical Colleges for his outstanding contribu-
tions in promoting opportunities for minority students in veterinary medical education. Even
after retirement, Archbald has continued to advise and mentor minority students in the D.VM.
and graduate programs.
The college's Special Service Award went to Jerome Modell, M.D., a professor emeritus
of anesthesiology at UF's College of Medicine who also holds a courtesy appointment in the
College of Veterinary Medicine. For more than 20 years, Modell, always eager to draw parallels
between animal and human patients, routinely invited UF veterinary faculty to lecture in his
classes. In the 1980s, he helped create a human patient simulator to teach medical students.
This tool was soon adapted to teach anesthesia to UF veterinary students.
The awards will be presented May 23 at the Phillips Center for the Performing Arts
during college commencement exercises.
