Certified Professional Food Safety (CP-FS) Practice Exam

Which practice helps to control food temperatures in storage?

1. Regularly checking refrigerator temperatures

2. Keeping doors open for airflow

3. Storing cooked and raw foods together

4. Using ambient air temperature

The correct answer is: Regularly checking refrigerator temperatures

Regularly checking refrigerator temperatures is crucial for controlling food temperatures in storage. This practice ensures that the refrigerator is operating within safe temperature ranges, typically below 40°F (4°C) for perishable foods. By monitoring the temperature regularly, you can detect any fluctuations that might indicate a malfunction or inefficiency in the refrigeration system, which can lead to food spoilage or unsafe food conditions. Maintaining appropriate temperatures is essential for minimizing the risk of foodborne pathogens, which thrive in improper temperature ranges. Regular temperature checks enable prompt corrective actions, such as adjusting the thermostat, repairing equipment, or relocating food items if necessary. This proactive approach helps ensure that food remains safe for consumption and prolongs its shelf life. In contrast, keeping doors open for airflow can actually lead to temperature fluctuations, making it more difficult to maintain a consistent environment for food storage. Storing cooked and raw foods together increases the risk of cross-contamination and can compromise food safety. Using ambient air temperature is insufficient for ensuring food safety, as it does not accurately reflect the temperatures at which food is stored.
