Mr McDonald, star of TV ads that urge customers to "bring your jumper", says legal action has been taken by Super Butcher against those responsible for a whispering campaign about the business.
"There's no doubt there are some people out there that don't like to see Super Butcher doing well," he said.
"There was a very strong rumour, we had to dispel it, we found the culprits who started it and they're people I don't do business with."
Asked how the business is faring, the 41-year-old insists: "Exceptionally good."
A Gold Coast riverfront mansion in the name of his wife Elise and the Yatala industrial site that hosts Super Butcher's main retail outlet are on the market.
A company connected to his wife bought the Yatala industrial site only a year ago for $3.3 million, and if it sells, the business will return to operating there on a rental basis.
The sell-off comes after a rapid expansion to seven Super Butcher outlets across the state's southeast and in northern NSW, including a factory outlet at Eagle Farm.
"Ultimately, I'd like to sell one of the properties because we've just had so much growth, so we'll put the two of them up," Mr McDonald said.
At Yatala, customers continued to arrive in droves last week to shop for bargains in a giant freezer with rock music blaring in the background.
But it has not been plain sailing for the Super Butcher business, with enemies sharpening their knives and a potential rat in the ranks.
Two days before Christmas, a gang cut through the cold room walls at Yatala in the dead of night and used a forklift to remove a 1000kg safe bolted to the floor in a secure room.
The operation dodged sensor alarms and netted an undisclosed quantity of cash from the year's busiest day of trading.
"There is no doubt it is an inside job . . . and I can't wait to find out out who it was," Mr McDonald wrote in a blog last week.
Insurance will cover the stolen cash, however nothing can be done about the disruption. It was the fifth break-in at Super Butcher outlets in eight weeks.
Frequent media appearances have portrayed Mr McDonald as a people's champion, taking on the big supermarket chains for "ripping off" struggling consumers.
However, with a former failed business in his history, the PR campaign has not won over everyone and attracted the attention of meat industry players, who have been watching Mr McDonald's progress intently.
In 2007, Mr McDonald's Murgon-based South Burnett Beef abattoir went bust amid turmoil in Asian export markets, leaving 350 people out of work and 150 creditors claiming they were owed $17 million.
Cattle suppliers and local businesses who lost money now switch on the TV to see Mr McDonald spruiking himself as the face of the Super Butcher.
As a bankrupt, he is unable to be a company director.
Super Butcher is owned and operated by his wife and other investors.
But he is the face of the operation and the ads have made him the country's most famous butcher.
One creditor, who lost about $100,000 when the abattoir closed, fumed of the TV ads: "He has a hide."
When things go wrong in the industry it can spell disaster for smaller suppliers, who require payment within a fortnight to stay afloat comfortably, and just such a scenario occurred around the corner at the rival Meat Warehouse factory outlet.
Kevin Masterson and his company Bedrock Beef and Reef had been caught up in a high-profile "meat war" with Mr McDonald after opening the Meat Warehouse outlet just 800m away from the Super Butcher's Yatala store.
Ultimately, Mr Masterson lost out, with Bedrock Beef and Reef now in liquidation.
"You can either hop back up on the horse or you can sit down and fold the arms and cry for the rest of your life," Mr McDonald says. "We came back by deadset luck and by chance this concept took off."
