Press Release:

Dear Racing Participant,

Early this morning we were informed of a system malfunction that incorrectly placed multiple horses on the HISA Vet’s List for clenbuterol.  This was an error, and we apologize to anyone who was impacted.  The issue has been identified and all affected records have been corrected. 

Racing offices have been informed.  

If you have any questions, please contact Dr. Jennifer Durenberger at Jennifer.durenberger@hisaus.org
