We had a small cheap chest freezer in the kitchen which was
infrequently opened it contained 2 large turkeys (Free from ASDA)
sundry frozen food and lots of ice lollies. We started to notice a
faint off smell in the kitchen that we couldn't track down. Eventually
we got closer, and moving a pile of towels on the lid cracked it open
3-4 mm. The most awful, rancid, putrid smell of stinking carrion and
fermenting orange juice (from the lollies) filled the kitchen.

When we got rid of our old freezer we defrosted it before arranging for the
council to collect it. Unfortunately I missed 3 prawns hanging around in the
back of one of the drawers. Two weeks hence I had to move the thing and
opened the door - I don't think I could describe the smell.....
