Question: How long can [century eggs](http://en.wikipedia.org/wiki/Century_egg) 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](http://nookandpantry.blogspot.com/2007/05/century-eggs.html) have suggested people have eaten unrefrigerated century eggs stored in a pantry for half a year with no ill effects.

Edit: It tasted great.

Answer: 
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.
My friend in Taiwan says they will keep refrigerated for up to 5 months - possibly longer but why risk it?
