How long does leftover pizza last?

According to EatByDate.com, pizza stays good for three to five days in the refrigerator. Frozen pizza and takeout pizza left on the counter should be discarded after a day. Homemade pizza should never be left out.

The best way to store pizza is in an airtight container. Uncovered or improperly stored pizza can spoil when exposed to moisture or contaminants. All types of pizza can be frozen. Typically, pizza lasts from four to six months in the freezer. However, pizza should be wrapped tightly in plastic wrap and placed in an airtight container before it is saved in the freezer.
