During transporting foods, what must be monitored continuously to prevent contamination?

• A. Color
• B. Temperature
• C. Packaging design
• D. Labeling

Answer: (B)

Keeping temperatures under strict control during transport is essential to prevent contamination. Bacteria multiply rapidly in the danger zone, roughly 41°F to 135°F (5°C to 57°C). By continuously monitoring temperature, you can detect any deviation from safe ranges as soon as it happens than can catch a failing cooler, door left ajar, or unexpected warm spell in transit. Using calibrated thermometers or data loggers with alarms in each transport unit, and recording readings regularly, allows quick corrective actions like returning to proper cold storage or reheating to safe temperatures. This approach keeps foods out of the danger zone and reduces the risk of harmful bacteria or toxins. Color, packaging design, or labeling don’t provide real-time safety monitoring during transit, even though they can influence handling or perception of quality.
