Worker finds a 2,000 year old 22lb hunk of butter buried deep in an Irish bog (and yes it is still edible)

A worker has found a massive 22lb lump of butter (pictured) dating back 2,000 years buried in an Irish bog - which is still edible. 

Jack Conway, a turf cutter from Maghera, northern Ireland, discovered the ancient white dairy product, which 'smelled like cheese', while working on Emlagh bog last week.
