how long do pineapples keep
Fresh cut pineapple could last up to 5 days in the fridge. Exactly how long will depend upon the fridge temperature and any contamination that might have occurred.I have had cut pineapple keep for nearly two weeks, but that might be an exception.ut pineapple â¦ lasts a couple of days if placed in a tightly covered container and stored in the refrigerator. (emphasis added)     Therefore, whole pineapple 2-4 days, cut pineapple 1-2 days. 13 people found this useful. Kodiakcathy.
