Signs of Spoilage
- •Significant sprouting (small sprouts can be removed)
- •Wrinkled, shriveled, or excessively soft texture
- •Green discoloration (indicates solanine, which is toxic in large amounts)
- •Mold growth (white, blue, gray, or black spots)
- •Unpleasant smell
- •Bitter taste
- •Significant dark spots that extend into the flesh
Storage & Reheating Tips
- •Store potatoes in a cool, dark, well-ventilated place (45-50°F/7-10°C)
- •Keep potatoes away from onions, as gases from each cause the other to spoil faster
- •Don't wash potatoes until ready to use, as moisture promotes spoilage
- •Store in paper bags, cardboard boxes with holes, or mesh bags rather than plastic
- •Check stored potatoes regularly and remove any that show signs of spoilage
- •If potatoes begin to sprout, they're still usable if firm - just cut away the sprouts
- •For longer storage of cooked potatoes, consider freezing mashed potatoes or potato-based dishes
- •Don't store potatoes in the refrigerator as cold temperatures convert starch to sugar
Food Safety Reminder
When in doubt, throw it out! Food can harbor harmful bacteria without visible signs of spoilage.
