If you look at the Stewards Reports you will see it is not unusual for only 2 pre-race swabs to be taken for a whole meet in Vic

Pre race swabs are virtually the only way to detect bicarb administered pre race by tubing (unless a horse is kept back 3hrs after racing for a swab)

You would think we should be doing way more than 2.
I would think at least 1 horse every race like we generally do for Metro meets

The Bendigo meet on Mar 27 for which Hanging On A Dream was a late scratching and for which Jennifer Douglas was later disqualified had 97 starters and only 2 pre-race swabs

If she had not be caught at her stables, there was only about a 2% chance she was going to be caught with a pre-race swab at the track
