Food rotted in my Liebherr fridge due to an (uninsured) handyman throwing the wrong switch in the fuse box. I discovered the mess and the stench 3 weeks later when I returned home. I have tried open boxes of baking soda, odor absorbers from the hardware store, and even cardboard on each shelf and in bins. The odor isn't as powerful but is still quite noticeable to "virgin" noses. I have not yet cleaned the fridge with bleach or any other disinfectant.
