McCabe said he found the emergency door release button inside the freezer -- which was set to a temperature of -4 degrees -- had frozen solid.
"No-one could hear me banging. Black pudding saved my life," McCabe told the BBC.
The butcher said he used the frozen blood sausage as a battering ram to operate the frozen button.
"It was the right shape. I used it like the police use battering rams to break door locks in. It was solid, pointed and I could get plenty of weight behind it," he said. "I'm lucky really. We sell about two or three each week and that was the last one in there."
