Food poisoning is no joke. Unfortunately, many people are unaware of how fresh the food in their fridge and freezer are when they return home from a long trip or vacation. If the power went out for a day or two (sometimes a few hours will do the trick), meats and other temperamental products could defrost and go bad.
Rather than deal with the consequences of eating spoiled food, try this trick provided by Brightside. Before you leave the house for an extended period of time, fill a cup with water and place it in the freezer. When the water is frozen, place a coin on the top and return it to the freezer
If you return to your home and see that the coin is at the bottom of the cup, this is a clear sign that the power was out long enough for the food to melt and re-freeze. In this scenario, it is probably best to dispose of the sensitive food items.
