Certified Professional Food Safety (CP-FS) Practice Exam

What is the standard foot-candle level required in grocery stores for food preparation?

1. 10 foot-candles (110 lux)

2. 30 foot-candles (320 lux)

3. 50 foot-candles (540 lux)

4. 100 foot-candles (1076 lux)

The correct answer is: 50 foot-candles (540 lux)

The standard foot-candle level required in grocery stores for food preparation is set at 50 foot-candles (540 lux). This level of illumination is important for ensuring safety and efficiency in food handling tasks, allowing workers to clearly see and accurately perform necessary actions, such as reading expiration dates, inspecting food for freshness, and following proper safety protocols. Adequate lighting not only enhances the visibility of surfaces and food items but also reduces the risk of accidents and cross-contamination. The chosen standard of 50 foot-candles strikes a balance between being bright enough for detailed tasks while also being energy efficient compared to higher levels of illumination. In contrast, lower lighting levels such as 10 or 30 foot-candles may not provide sufficient visibility for the detailed work that goes into food preparation, potentially compromising food safety. Levels higher than 50 foot-candles, such as 100 foot-candles, may result in unnecessary energy use without substantial benefits in visibility for standard food preparation tasks. Thus, the 50 foot-candle standard is established to ensure a safe and effective food preparation environment.
