The shelf life of pizza in the fridge depends on various factors such as the toppings, storage conditions, and how it was prepared. In general, pizza can be stored in the refrigerator for 3 to 4 days. However, it's essential to properly store it in an airtight container or wrapped tightly in plastic wrap or aluminum foil to prevent it from drying out and absorbing odors from other foods in the fridge. Additionally, if the pizza has perishable toppings like meat or dairy, it's best to consume it within 1 to 2 days to ensure food safety. Always use your best judgment and check for any signs of spoilage, such as an off smell or appearance, before consuming refrigerated pizza.
