Throw Out Your Leftovers Day

National Throw Out Your Leftovers Day is observed in the United States on November 29^th. The purpose of this holiday is to encourage people to check their refrigerators and discard any spoiled food that’s been sitting too long. We’ve all been guilty of this, and today serves as a reminder to be mindful of what we have at home.

History

Hoarding leftovers often stems from misjudging portion sizes. Families may cook more than they eat, then store the excess in containers or on plates—only to let it spoil. Not only can this create unpleasant odors, but spoiled food can also be toxic. This day encourages everyone to throw out expired items and learn how to better gauge future meal prep.
