Which of the following is the correct minimum lighting level for working surfaces in food preparation and related areas?

• A. 50
• B. 200
• C. 100
• D. 75

Answer: (C)

Having enough light on the work surface is essential for safe food handling and accurate work. Adequate illumination helps workers clearly see joints, edges, textures, and color changes, making it easier to spot contamination, measure ingredients correctly, and sanitize tools properly. The minimum standard for working surfaces in food preparation and related areas is 100 foot-candles of light directly at the surface. Lower levels, like 50 foot-candles, can obscure detail and increase the chance of overlooking debris or misreading labels. A level around 75 foot-candles isn’t the recognized minimum in these guidelines, and 200 foot-candles, while brighter, is typically more than necessary and wastes energy. So, 100 foot-candles on the work surface is the appropriate minimum.
