it is a bad bad bad idea to not keep cheese in the fridge..
yeah, 50 years ago it wasnt kept in the fridge at all, but then there were none of the added chemicals in it..
take the elements of cheese back to the source, even the cows would have been fed artificial man-made additives the milk was then treated, all of the other ingrediants are from less natural sources,
the end product is designed to live in a cool environment,
cheese that is past its date or not kept chilled should be thrown away, you cant see or smell the bacteria that could poison you... mould is a sure sign, and slicing the mouldy part off is no good either because the mould spores and bacteria grow through the entire block before making marks on the surface..
just because it looks ok, doesnt mean it is, and for a �3 block of cheese you are risking a week off of work with your head in the toilet...
Staphylococcus Aureus is unlikely to actually kill you, but it can put you out of action for a few days..
