"I am hoping the RIU [Racing Integrity Unit] investigations will show that but I won't be getting into a big legal battle with them.
"The facts are the facts and I know we never use anything inappropriate on the horses so I don't want to get into a big legal stoush over it.
"So hopefully the right things happen because if something like this ended up in me getting time that would be the end of my career, which would be ridiculous. But while I am gutted at what has happened, my conscience is clear."
Southern trainer Shane Walkinshaw was found to have not committed any wrongdoing last year when a cobalt positive returned by one of his runners was found to have been caused by contaminated feed.
Dalgety is a far bigger name in the racing industry, as not only a premiership winner but the trainer of $2.4 million earner Christen Me.
RIU boss Mike Godber told the Herald his inspectors had taken samples of food and supplements from Dalgety's stable and the analysis of those products would be crucial to the next step in the investigation.
"Cran's other horses had been returning higher than usual cobalt readings for a few weeks so we need to see if his change in feeding and supplements used was the cause of that. That won't be a quick process but that is the next step in the investigation."
