Raw potatoes last about 1-2 weeks at room temperature, but can last much longer (up to 2-3 months) in a cool, dark, well-ventilated spot (45-50°F), while cooked potatoes should be refrigerated within a few hours and eaten within 3-4 days, as they spoil quickly. Storing them in light causes greening and potential toxin buildup, while refrigeration converts starch to sugar, affecting taste. 

How do I know if my potatoes have gone bad?

You can tell if potatoes are bad by checking for soft, mushy spots, a musty smell, wrinkled skin, visible mold, or extensive sprouting, which are all signs of spoilage; slightly green areas or small sprouts can often be cut off, but a strong odor or significant greening means you should toss them due to potential solanine toxins.
