Peter Moody admits he is close to walking away from racing after being embroiled in raceday treatment probe.

The trainer, already up on cobalt charges from Lidari's placing in last year's Turnbull Stakes, is facing a raceday treatment charge after Lady Tatia was scratched from a race meeting at Pakenham on Wednesday.

And Moody, who trained Black Caviar throughout her unbeaten 25-start career, has made explosive claims against Racing Victoria's integrity unit, alleging it wanted to plant a worker in his stable to inform on him.

He said past and present Racing Victoria powerbrokers were aware of his claims.

Lady Tatia was withdrawn by stewards after RV's integrity department visited Moody's stable on Wednesday morning and found the mare had a medicated clay poultice applied to her forelegs.

Moody accepted full responsibility after one of his staff mistakenly applied the poultice which is banned under raceday rules.

He said he loved the racing industry that had created a great living for him but admitted it was starting to wear thin.

"I've got to the point where I don't care and that really saddens me," Moody said during a Racing.com interview.

"It's affecting my business, it's affecting my mentality and it's affecting my ability to train my horses."

Moody said his legal team would not be happy with his outburst.

He says he might not be willing to risk his finances in fighting his cobalt case.

"I'm not going to make a rash decision," he said.

"I will have a chat with my legal team tonight, my wife, take it all in.

"It's becoming a pretty thin piece of glass I'm looking through at the moment."

Moody said common sense should have prevailed in the scratching of Lady Tatia because the rule states the horse `may' be scratched.

"I've done the wrong thing, yes, penalise me, but don't penalise the owners," he said.

He said his latest predicament was a result of the Australian Racing Board taking a lot of the control away from stewards and making sudden announcements without consulting the industry.

Moody believes trainers are faced with a rule book that is too hard to adhere to and too difficult for stewards to police.

"Am I bad for this industry. Maybe people out there think I am, (then) maybe they need to take my licence off me and push me away," he said.
