That definitely qualified for a bio-hazard!
Our office fridge. Three of us cleaned it out today -- I had volunteered to dispose of the food, since I can't smell. Everyone on our floor was sent an email by the organizer of this dangerous expedition, and anything that wasn't marked/labelled got trashed. That was 98% of the "food," and I use that word loosely, in both the freezer and fridge. Lots of disgusting items, but only one that made me scream at the top of my lungs as I was hauling it out. The entire building heard me for that one, actually. But it's done. This time. And I came away with a very handy glass butter dish that no one claimed. If someone asks where it went I'll happily return it; otherwise, it's mine. :-) BTW, every cartoon/joke you've seen/read about the stereotypical office fridge is true! Have a hazard-free weekend, everyone. :-) The cartoon I printed out and taped to the fridge, after we were done.
