How do you know if potatoes are ruined?

How do you know if a potato has 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.
 

What do potatoes look like when gone bad?

Are slightly wrinkled potatoes safe to eat?

Wrinkled potatoes are often dehydrated and past their prime, but usually safe if still firm and you remove sprouts/green parts; however, if they are soft, mushy, green, sprouting heavily, or smell bad, they are likely starting to decay, producing solanine (a toxin), and should be discarded, as they lose flavor and risk causing illness.
 

How long can uncooked potatoes last in the fridge?

Raw, whole potatoes shouldn't really be stored in the fridge long-term because the cold converts starch to sugar, affecting taste and causing discoloration when cooked, but cut or peeled potatoes submerged in water in the fridge last about 24 hours, while cut potatoes uncovered can last 3-4 days but should be used quickly. For whole, unpeeled spuds, a cool, dark pantry is best, where they can last 1-2 months.

If the potato is extensively sprouted, soft, green, or has a bitter smell, it's best to throw it out to be safe. 

What do rotten potatoes smell like?

A rotten potato smell, often described as like rotten eggs or cabbage, comes from sulfur compounds like hydrogen sulfide and methyl mercaptan, caused by bacteria breaking down the tuber.

Use slightly soft potatoes in mashed potatoes, soups, or stews where texture isn't as critical as baking or roasting, and remember to remove the sprouts and any green parts as they can contain toxins like solanine, though normal amounts are usually fine.
 

How to avoid food poisoning from potatoes?

Store potatoes in a cool, dry, dark place. Peel the potatoes before cooking can reduce the amount of glycoalkaloids. Cut away any parts that show damage (cuts and bruises), rotting, green colouring and sprouting before cooking. In severe cases, discard the entire potato.
