balt will only be penalised when present on a race day . However , other unscheduled preparations ( for e . g . Aspirin , which is available without prescription ), must be entered into the VTR by the Trainer when administered . Beware of utilising any “ Over the Counter ” medication without consulting your vet regarding its composition and possible “ prohibited substances ” present in the formulation .

NOTICE TO ALL TRAINERS International Screening and Residue Limits and Asian Screening Limits The NHA hereby advises it has adopted International Federation of Horseracing Authorities ( IFHA ) International Screening Limits ( ISLs ) to be applied in the control of therapeutic prohibited substances and also IFHA Residue Limits to control certain contaminants and environmental substances . In addition to this the NHA , as a signatory country of the Asian Racing Federation , has adopted several Asian Screening Limits ( ASLs ) for therapeutic prohibited substances . Details of these screening limits can be found in the section “ International Screening Limits ” in the “ Laboratory ” section of the website .

NOTICE TO ALL TRAINERS THE USE OF ASPIRIN ( ACETYLSALICYLIC ACID ) IN THE RACEHORSE Salicylic acid is a substance found in the normal feed of horses such as lucern and hay . During previous years large populations of racehorses from all over the world were screened for natural levels of salicylic acid which is ingested in such feeds . Considering the possible diets of horses and worst case scenarios , a single salicylic prosecution threshold was decided on an international basis . This International Federation of Horseracing Authorities ( IFHA ) threshold has been established with an extremely high probability that untreated horses on a variety of feeds will present levels far below this salicylic acid threshold . The NHA has formally adopted this threshold : “ Salicylic acid …… 6.5 micrograms salicylic acid per millilitre in plasma ” as shown on the website . A specimens is only declared a positive finding when the concentration of salicylic acid is accurately confirmed ( full quantitative analysis is conducted as part of such a positive finding ) to exceed this threshold , in accordance to Rule 73.4.4 . It is know that Aspirin can be added to the feed of horses to acts as an analgesic and antiinflammatory substance . Acetyl salicylic acid ( Aspirin ) is however a pro-drug of salicylic acid , implying that Aspirin will be converted to salicylic acid within the horse . As Aspirin it is not a scheduled substance ( in contrast to most analgesic and anti-inflammatory substances ) it can be readily obtained by all . The administration of Aspirin to the racehorse must be recorded in the Veterinary Treatment Register of the horse . The use of Aspirin too close to race day is likely to result in salicylic acid prosecution . Be aware that guidance of the use of Aspirin products in the horse Home About the NHA Racing Studbook Laboratory Veterinary & Welfare Ownership & Registration Statistics Contacts http :// www . nhra . co . za / notices . php 2017 / 01 / 17 , 2749 PM Page 1 of 5 differ between different manufacturers . Following the administration of a single dose of Aspirin a detection period of a two days applies ( this is not a withdrawal time ). Consult your veterinarian in regards to a suitable withdrawal period . The NHA does not assume any legal , professional or other responsibility or duty whatsoever as to the accuracy of the data presented in this document . Please note that reliance on and use of the above information does not absolve or diminish a trainer or owner from being responsible for ensuring that the horse complies with the rules relating to the presence of drugs and prohibited substances when presenting a horse for a race .
