If you’re facing ice storms, snowstorms or other severe weather that could knock out your power this winter, you may be in the position of having to quickly take action to protect the food and beverage you’re refrigerating or freezing – and to determine what needs to be discarded. Don’t trust your nose or your taste buds in these situations, since they can’t necessarily detect when something is still fit to be consumed. You’ll be in a better place to salvage your food and beverage if you take steps in advance to store them in a way that enhances quality and freshness from the start. One tool that can help is the FoodKeeper app. Developed by the USDA's Food Safety and Inspection Service, with Cornell University and the Food Marketing Institute, the app (available for Apple and Android) lists optimal storage information for hundreds of items in your inventory.
