When should you not eat potatoes?

Potatoes are bad to eat when they are moldy, smell foul, are excessively mushy, or have significant greening or long sprouts, as these indicate high levels of the toxin solanine or spoilage; however, you can often salvage slightly soft or sprouted potatoes by trimming off the bad parts. Always toss potatoes that are entirely green, have black spots that smell bad, or are liquidy.

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

Why are my potatoes leaking brown liquid?
