LIVE exports out of Port Alma would be "unequivocally bad" for Rockhampton, according to local abattoir Teys Australia.
Teys' general manager for corporate affairs, Tom Maguire, said there were hundreds of millions of dollars in value adding in the supply chain.
"We understand from a producer's point of view they want to have more choices, but for the city of Rockhampton live exports out of Port Alma would be unequivocally bad," he said.
"It means decreased value into the economy and less people we're able to employ."
Teys Australia is one of the biggest employers in the Rockhampton region.
Rockhampton MP Bill Byrne yesterday slammed Keppel MP Bruce Young for supporting the proposal during a media conference at Teys Meatworks.
He said claims the market would benefit producers were "nonsense", and while price issues would improve dramatically in short to medium terms, there were no financial advantages in the long run.
He also said if the proposal goes ahead it will threaten a considerable number of jobs in Rockhampton.
"I am all about defending and creating local jobs, rather than exporting them overseas," he said.
Mr Maguire admitted Teys' is at capacity at the moment and Teys is unable to take cattle for weeks. But he said that would come to an end soon.
"We know the cattle market is going to be very tight in the coming years," he said.
Figures from Meat and Livestock Australia indicate that 2.5 to 3 million fewer cattle will be entering the market.
Mr Maguire also added that in northern Australia, where the live export market exists, 15 meatworks have closed since the 1970s.
