Kentucky performs fewer drug tests on racehorses and has fewer positive results than most other states, the state auditor said in a report released on Monday.

Auditor Crit Luallen said the Kentucky Horse Racing Authority needs to enforce rules against performance-enhancing substances to the fullest extent possible. She made the statement after reviewing the results of drug tests from 10 other key horse racing states in 2005.

“Because horse racing is our signature industry, it is very important that we have the strongest regulatory agency in the country,” Luallen said. “This is an important part of this authority’s responsibility, and it’s critical that they improve that process.”

To ensure the public’s trust of the horse racing industry, Kentucky should be a leader in banning illegal substances, the audit report said
