No one gives a damn that for years we have had halal food stuffs foisted on us, as been proved, so i really don't care if by mistake a little bit of pork dna finds it's way into prison food. If they have been eating beefburgers then that could also have traces of pork, no one is the wiser. Now they know they can rectify the matter, but honestly if you don't want to eat prison food, and i suspect that it isn't all that pleasant then don't do the crime.
