If you plan to go on vacation and leave food in the freezer, here’s a simple trick to check if it’s still safe when you return. Power outages can cause frozen food to thaw and spoil without you knowing.
Sheila Pulanco Russell shared an ingenious method: place a cup of water in the freezer until solid, then put a coin on top and leave it there. When you come back, check the coin’s position—if it’s at the bottom, your food completely thawed and should be discarded.
If the coin is on top or in the middle, the freezer likely stayed cold enough to keep food safe. This “one cup tip” is easy, inexpensive, and useful year-round. When in doubt, throw the food out to avoid health risks. Share this tip to help others keep their groceries safe during power outages.
