A Melbourne Airport traveler is in a bun fight with a fast food franchise after claiming he chowed down on a moldy burger.

Cameron Baker said he’s still looking for an apology from Oporto after biting into what he claims was a mold-ridden burger at its Melbourne Airport store in October last year.

He said he had eaten most of the burger before realizing there was an extra condiment and took it to the manager, who had promised he would be contacted by someone.

But according to Mr Baker, he was contacted by Delaware North, which manages and delivers catering and service at various retail outlets at Melbourne Airport.

He claimed they had “accepted no responsibility for the moldy burger” and had informed him not to discuss it with anyone.

“Everybody just tried to sweep it under the rug,” he said.

“(They told me) ‘we consider this matter closed’.”

Mr Baker had been on a stopover in Melbourne on his way back to Queensland following a short stint in Hobart.

He said he’d been immediately unwell as a result and had, until recently, been unable to eat meat.

He said he was slowly starting to eat meats again.
