According to the FDA Food Code 2022, what is the recommended guideline for hand-washing sinks in food establishments?

At least one hand-washing sink is required in or near all food preparation, food dispensing, and warewashing areas. The FDA Food Code 2022 (§ 5-203.11) mandates that hand-washing sinks must be conveniently located in or near key areas like food preparation, dispensing, and warewashing zones. While it does not prescribe a fixed ratio (e.g., per number of handlers), it emphasizes accessibility to ensure proper hygiene. Options A, C, and D are incorrect because the FDA does not specify sink-to-handler ratios or restrict sinks to restrooms.
