Which of the following are signs of potentially hazardous food?

• A. Time-temperature abuse, cross-contamination, improper storage or spoilage indicators
• B. Bright aroma and crisp texture
• C. Excellent color and uniform size
• D. Short cooking time

Answer: (A)

The essential idea is identifying factors that show food could be unsafe to eat. Potentially hazardous foods are those prone to harboring pathogens if not handled properly, so signs include time-temperature abuse, cross-contamination, and improper storage or spoilage indicators. Time-temperature abuse means food has stayed in the temperature danger zone long enough for microbes to multiply. Cross-contamination happens when pathogens move from one contaminated surface or food to another, such as using the same cutting board for raw meat and ready-to-eat items. Improper storage or spoilage indicators cover storing foods at wrong temperatures, poor labeling, or visible signs of spoilage like off odors or unusual textures. The other options describe desirable sensory qualities or cooking speed, which don’t indicate safety risk.
