how long does a pineapple last in the fridge after it's been cut?
Once you cut a fresh pineapple, it will last in the refrigerator only 5-7 days. The best way to store it is to cover it in juice in an airtight container, and for better taste let it come back to room temperature before eating it again.
Cut fresh pineapple should be stored in it's own juices if possible in the refrigerator. It will generally last from four to six days.
