What does a bad potato 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. This indicates the potato is spoiled and unsafe to eat, but the odor can also stem from issues like plumbing leaks (hydrogen sulfide) or even certain bacteria in hospitals. To eliminate the smell from surfaces, use vinegar, baking soda, or coffee grounds to absorb it, and ventilate the area well.
