Question: do pineapples have a shelf life?
Answer: Generally, pineapples don't last that long. A whole pineapple should retain quality for 1 to 2 days at room temperature, or 4 to 5 days in the fridge. And it should stay okay-to-eat-but-not-that-great for at least a couple more days. ... If you need to store the pineapple for longer, freezing is the way to go.
