Racing NSW is aware of the Racing Victoria warning published at 5.45pm on 19 June regarding veterinary prescription animal remedies containing the progestagen altrenogest, used to control the cyclic activity of fillies and mares.

It has been recently discovered that certain batches of altrenogest products may contain low level traces of trenbolone and/or trendione. Racing NSW is conducting its own investigations into this matter.

Until the situation is clarified, NSW trainers and veterinarians should avoid using injectable products containing altrenogest, and as a precaution, should not administer oral altrenogest products within one clear day prior to racing.

Trainers are reminded of the requirement for all treatments to be recorded by midnight on the day on which the treatment was given.
