LEXINGTON, Ky. – The Association of Racing Commissioners International has claimed in a report released Thursday that, in 2010, fewer than half of 1 percent of U.S. equine drug tests came back positive for a substance not allowed on race day.
According to the RCI report, racing regulatory agencies sent 324,215 biological samples to testing laboratories, and more than 99.5 percent were found to contain no foreign or prohibited substance.
Thirty-two U.S. jurisdictions responded to the RCI’s survey for this report.
