Which of the following areas requires at least 20 foot candles of light?

The requirement for at least 20 foot candles of light in displays and buffet areas is important for several reasons. Adequate lighting in these areas ensures that food presentation is appealing to customers and allows staff to properly inspect and serve food. Good visibility helps prevent potential contamination risks by enabling employees to see any possible hazards, such as food spoilage or issues with cleanliness.

In contrast, while food prep areas also require good lighting for safety and hygiene, they typically have different standards for brightness. Walk-in refrigerators often require less light because the primary focus in these areas is on maintaining temperature, not visibility. Dry food storage areas also have less stringent lighting requirements, as the focus is more on storage conditions than on food display or customer interaction.
