What is an indication that food may have spoiled due to improper storage?

The presence of an unusual texture in food is a clear indication that spoilage may have occurred due to improper storage. When food is stored incorrectly, microorganisms can grow and alter the food's natural properties, leading to changes in its texture. For instance, fruits and vegetables may become mushy, while meats can develop a slimy or sticky surface. These textural changes signal that the food is no longer safe to consume, as they often indicate microbial growth or deterioration.

Bright color does not inherently indicate spoilage and may sometimes suggest freshness, especially in fruits and vegetables. The presence of artificial preservatives often helps to prolong the shelf life of food, preventing spoilage rather than indicating it. Cooling consistently reflects good storage practices and can prevent food from spoiling, so it does not indicate spoilage either. Thus, unusual texture is a key indicator of potential spoilage from improper storage.
