If the testing by thr HKJC is so unfair, where are all the positives arising out of the most tested racehorses of any country. The NZ industry was warned that some swab samples were to be sent to the HKJC and you now can see the result. It is easy to go to the HKJC website and have a look at their document 'A List of Questions that are Frequently Asked by Visiting International Trainers' where it would seem blatantly obvious what they are about.
It seems that overseas galloping trainers do just that (except Joe Janiac) as positive swabs are at a minimum.
