I lost power during Sandy for 36-48 hours. My freezer items with a few exception of door items that were not packed in tightly mostly stayed frozen. I cooked the veggies and defrosted carbs, meats went. My fridge stayed good. One thing I did was I knew that we would most likely lose power as most of the areas around us had so before I went to bed I took chunks of ice I had put in the freezer in the fridge (tupperware containers full, not just giant ice cubes). When the power came back on I discovered the containers were still almost frozen solid in the fridge so I know it had stayed at a safe temperature. This is a good tip for next time you suspect you might lose power. I did this because I heard a tightly packed freezer would stay colder longer, but then I realized I had way more fridge food that would go bad than freezer so at the last minute I made the swap. I also kept everything closed the entire time which was hard but paid off.
