Your fridge could make you sick if you don’t clean it every once in a while. NSF International swabbed 20 Michigan kitchens as part of its 2013 Household Germ Study, and two of the germiest places were the vegetable and meat compartments in refrigerators. First, unplug the fridge and empty it out. Toss old containers and expired food, and wipe everything down with multipurpose spray. Soak drawers in warm water and scrub them clean with dish soap. These are the foods you should never keep in a fridge.
