Refrigerator
According to the Center for Disease Control, 21% of U.S. outbreaks of food-borne illness with a known single setting resulted from food consumed in a private home. While it might get you a day off of work, you also won’t be able to eat which means really nobody wins.
Solution: Do a weekly fridge wipe-down and a once-a-month do a deep clean where you take everything out, toss any spoiled food, wipe down all surfaces and scrub removable shelves in sudsy hot water.
