• A. 100
• B. 50
• C. 40
• D. 75

Answer: (B)

A solid level of lighting in sanitation-critical areas is essential so you can clearly see surfaces and equipment to clean them properly and check for any dirt or residue. Foot-candles measure how much light lands on a surface, and the requirement for food preparation, utensil washing, hand washing areas, and toilet rooms is 50 foot-candles. This brightness level is bright enough to spot soil, read labels, and inspect cleanliness without causing excessive glare. Too little light, like 40 foot-candles, can hide contamination and make thorough cleaning difficult; much higher levels, such as 75 or 100 foot-candles, aren’t required for these spaces and would be more than necessary for routine sanitation. So, providing 50 foot-candles at the working surfaces in these areas ensures adequate visibility for safe, hygienic operation.
