What are the signs of potential food contamination?

Unusual odors, discoloration, and mushy textures are critical indicators of potential food contamination. These signs suggest that the food may have been compromised by bacteria, mold, or spoilage, which can lead to foodborne illnesses if consumed. For example, a sour smell might indicate fermentation or spoilage, discoloration can suggest spoilage or that the food has been exposed to harmful bacteria, and a mushy texture may signal that the food has started to degrade.

High freshness and vibrant colors, while generally indicators of good quality, do not necessarily guarantee safety. Food can appear fresh and bright yet still be contaminated. Similarly, consistent texture and uniform sizes are not reliable indicators of safety; they may merely reflect good processing practices. Clear packaging and proper labeling help in identifying and managing food safely, but they do not account for internal quality and safety issues that might not be visible through the packaging.
