Unopened milk shelf life varies by type. Pasturized milk is good for about 5-7 days past its printed date if stored properly in the fridge. Ultra-pasteurized or UHT milk can last 2-4 weeks past its date when refrigerated and up to six months when unrefrigerated until opened. However, always check for signs of spoilage like smell and texture changes before consuming.
