Lexington, KY - Approved at the FEI General Assembly in Taipei last November, the 2011 FEI Equine Prohibited Substance List for horses competing in FEI classes became effective April 4, 2011.  It is important for all who compete  in the FEI disciplines  to become  familiar with the parameters laid out by the FEI Clean Sport Initiative. The lists of Controlled and Banned substances are available at www.feicleansport.org . Additionally, the Athlete’s Guide can be found here . The searchable FEI Equine Prohibited Substances Database can be found here . Until June 4, 2011, the 2011 list will show all Prohibited Substances that have been added or removed from the 2010 List and Database. The FEI has also created applications for the iPhone and other smart phones, designed to show the latest changes to the rules as well as offer updates when any substances are added or removed
