Food poisoning is not a joke and a lot of people are not aware of how fresh food in the fridge or freezer are once they get back from a long trip or vacation. If the powers goes down, meats and other foods can defrost and go bad. If you don’t want to deal with the consequences of consuming spoiled food, then you should better try this simple trick.
Just fill a cup with water and place it in the freezer. Once the water freezers, place a coin on the top and return it back. When you get back home and see the coin at the bottom of the cup, then the power had went off long enough or the food to melt and re-freeze. You should better dispose the sensitive food items. If the coin remained on the top, then your food is safe.
Food waste is a serious issue in America. 40% of it ends up in trash, thus you better be safe than sorry in the event that the coin is at the bottom of the cup. Just throw away the items you are skeptical about.
