Ingestion of these plants by horses may lead to the alkaloids being detected in race day samples and the declaration of a positive swab.
The detection of hyoscine has been traced to contaminated sunflower seeds and clover hay sourced from North Western New South Wales and also in some pre-mixed feeds.
Trainers are advised to ensure that their horses do not have access to these plants and to check all feeds and supplements for the presence of unusual plant material.
