Only one B sample from nine horses tested on domestic circuit proves positive

JUST one of the nine A samples taken from horses on the domestic circuit that tested positive for a banned substance has been confirmed by a B sample positive, according to ShowjumpingIreland.

The fact that eight of the B samples tested negative, that all contained the same banned substance, betamethasone, and yet that they came from a wide geographical spread will add to the puzzlement.

ShowjumpingIreland veterinary committee chairman Ivan McDonogh conceded the situation was out of the ordinary.
