What is a requirement for handwashing sinks in a food establishment?

• A. A sign reminding workers to wash their hands
• B. Automatic faucets only
• C. A window for sunlight
• D. A thermometer

Answer: (D)

The key requirement at handwashing sinks is a sign that reminds workers to wash their hands. This helps ensure regular hand hygiene, which is critical to preventing cross-contamination. In addition to the sign, sinks must have hot and cold running water, soap, and a way to dry hands. The other options aren’t mandated features: automatic faucets aren’t required (manual or automatic are both acceptable), a window for sunlight isn’t a sanitation requirement, and a thermometer isn’t a required part of a handwashing station.
