In answer to the question posed: I do not know, however if said cheese was in a fridge in the breakroom at work and someone ate it, or took a nibble, then you may want to consider putting your initials on future food items, including cheese, that you place in a communal workplace fridge.
It is a great deterrent.
Unless greedy Margaret Price (yes - I know it is you) works in your building. Last week, despite my initials emblazoned across them she ate my orange, Snickers bar and took a bite out of my egg salad sandwich.
It is technically theft.
