What is a common sign of food spoilage?

A common sign of food spoilage is an off smell or unusual color. When food begins to spoil, it often undergoes chemical changes that result in altered odors and appearance. An off smell can indicate the growth of bacteria or mold, and an unusual color can suggest that the food is no longer safe to consume. These sensory indicators are critical for food safety, as they can help identify food that should not be eaten and prevent foodborne illness. Recognizing these signs is essential for proper food handling, storage, and preparation in any food service operation.

Smooth texture, bright, vibrant color, and firm consistency typically indicate freshness rather than spoilage. While these characteristics can be appealing in food, they do not serve as reliable indicators of spoilage, making the presence of an off smell or unusual color a much more concerning signal.
