How long can century eggs last refrigerated and unrefrigerated? How long can century eggs last for refrigerated and unrefrigerated? I have some slightly cracked eggs from a friend who has stored it for months in his refrigerator.

A few comments from this blog have suggested people have eaten unrefrigerated century eggs stored in a pantry for half a year with no ill effects.

Edit: It tasted great.
Was the limestone and hay wrapper cracked or the egg shells? 
Century eggs are really only a few weeks-months old, actually. Though they do keep for long periods at room temperature. They're also damn tasty and have a lot of ammonia i.e. Very high PH (basic) so unlikely to spoil.
