Before you get ready for the big game take 10 – 15 minutes and open that refrigerator. Throw away any expired items and leftovers.
Once opened many items can go bad after a day or two. Need help deciding? Check out the storage times chart found here: https://www.foodsafety.gov/keep/charts/storagetimes.html
Sometimes those expiration dates are hard to see. To keep your refrigerator up to date, every time you open a package, put a label with the throw away date on it.
