The Blood-Horse 11/7/2008
None of the horses that participated in this year's Breeders' Cup World Championships Oct. 24-25 at Santa Anita tested positive for steroids, blood-doping agents or TCO2 (bicarbonate), according to Pam Blatz-Murff, senior vice president of operations for the Breeders' Cup.
However, as of Nov. 8 test results for any other prohibited substances were not available because of the testing process used by the California Horse Racing Board.
