To tell if a carrot is bad,  check for softness, sliminess,  

and a white, dry appearance,  which indicates dehydration.

Fresh carrots are firm and crisp.  Inspect for dark spots or mold,  

signs of spoilage. Smell the carrot; a sour or  off odor is a clear indicator it's gone bad. If  

it's slightly soft but smells and looks okay,  it might still be good for cooked dishes but  

not ideal for raw consumption. Always trust your  senses; if in doubt, it's safer to discard it.
