The presence of off odors, discoloration, mold, and changes in texture are key indicators of food spoilage. These signs suggest that the food has undergone chemical changes or microbial action that compromise its safety and quality.

Off odors typically arise from the breakdown of food components, indicating that bacteria or other organisms are present and may be producing harmful substances. Discoloration can result from oxidation or microbial growth, which often affects the food's appeal and can indicate underlying spoilage. Mold growth is a clear visual cue of spoilage that signifies the presence of fungi, which not only affects the taste and smell but could also lead to health risks if consumed.
