Which of the following is a sign of food spoilage?

1. Bright colors

2. Off odors

3. Firm texture

4. Cool temperature

The correct answer is: Off odors

A sign of food spoilage is characterized by off odors. When food begins to spoil, it undergoes chemical changes due to bacterial growth and enzymatic activity, resulting in unpleasant smells. These odors are often an indicator that food is no longer safe to consume, as they signify the presence of decomposing substances and potential pathogens. In contrast, bright colors typically indicate freshness and ripeness in fruits and vegetables. Firm texture is also a sign of quality, suggesting that the food item is still in good condition. A cool temperature, particularly in the context of food storage, is essential for preserving the freshness and preventing spoilage, rather than indicating it. This context helps clarify why off odors are a clear signal of food spoilage.
