The International Federation of Horseracing Authorities have established international thresholds for:

  • substances endogenous to the horse
  • substances arising from plants traditionally grazed or harvested as equine feed
  • substances in equine feed arising from contamination during cultivation, processing or treatment, storage, or transportation.

As an International Federation of Horseracing Authorities member the National Horseracing Authority of Southern Africa applies these thresholds / concentrations which are provided below.


The concentrations listed above have been determined to be the maximum concentration permitted in a specimen taken from any horse.N.B.: The conjugated substance is the substance that can be liberated from conjugates.

In terms of Rules 73.4 and Rule 74 the abovementioned substances shall be prohibited substances if the concentration found in a specimen exceeds the concentration set out above.

Application of International Threshold Values to Out of Competition Testing collected specimens.

International threshold values for Testosterone, Estranediol, Boldenone, and Methoxytyramine are applicable to Out of Competition Testing collected specimens.


International threshold values for Hydrocortisone, Arsenic, Dimethylsulfoxide (DMSO), Cobalt, Salicylic Acid and Carbon Dioxide (total available Carbon Dioxide) are applicable to Out of Competition Testing collected specimens. However, these may not be actionable if a legitimate treatment is appropriately recorded in the relevant Veterinary Treatment Register.



N.B.: The conjugated substance is the substance that can be liberated from conjugates.

The concentrations listed above have been determined to be the maximum concentration permitted in a specimen taken from any horse.

In terms of Rules 73.4 and Rule 74 the abovementioned substances shall be prohibited / forbidden substances if the concentration found in a specimen exceeds the concentration set out above.
