How long does potato salad last once opened?
How Long Does Potato Salad Last? – According to FoodSafety.gov, potato salad lasts 3 to 4 days in the fridge, no matter if it’s store-bought or homemade. If there’s a use-by date printed, the salad should keep for a day or two past that date, but that’s it.
Once you open the container, store-bought potato salad still lasts for 1 to maybe 2 days past the printed date. Opening it up doesn’t magically reset the time and rewind the deterioration, and you don’t get another 3 to 4 days of storage. If it was already pushing its date, you should eat it within a day or discard it.
That 3 to 4 days of shelf life is a recommendation common for all types of salads.
