What are the signs of spoilage in food?

The signs of spoilage in food include off odors, discoloration, or unusual textures. These indicators suggest that the food has undergone changes that may make it unsafe to consume. An off odor can indicate the growth of spoilage bacteria or the breakdown of the food’s natural components. Discoloration may signify that the food is no longer fresh or that it has been affected by microbial growth or chemical reactions. Unusual textures, such as sliminess or mushiness, can further alert you that the food has deteriorated and may no longer be safe to eat. Recognizing these signs is crucial in maintaining food safety and preventing foodborne illnesses.

The other options do not reflect spoilage indicators. Fresh smells and bright colors suggest freshness, while consistent temperature and texture indicate that the food is being stored properly. Intact and sealed packaging signifies that the food has not been exposed to contaminants, which is typically a sign of good quality and safety rather than spoilage.
