If an operation chooses to use heat instead of chemicals to sanitize utensils in a three-compartment sink, specific temperature requirements must be met to ensure the destruction of pathogens. According to the FDA Food Code and ServSafe, the water in the third (sanitizing) compartment must be at least$171^{\circ}F$ ($77^{\circ}C$). Additionally, the items being sanitized must be completely immersed in this hot water for a minimum of30 seconds.

Maintaining this temperature is challenging in a manual sink and typically requires a heating element or "booster" to keep the water consistently hot. If the water drops below $171^{\circ}F$, it is no longer considered a reliable sanitizer. For comparison, $110^{\circ}F$ (Option A) is the minimum temperature for thewash(first) sink. $180^{\circ}F$ (Option D) is the temperature required for the final sanitizing rinse in a stationary rack, single-temperature machine or a high-temperature conveyor machine. Using heat-based sanitizing requires the manager to provide staff with a way to verify the temperature, such as a waterproof thermometer or heat-sensitive tape. This method is effective but requires strict monitoring to prevent staff from being burned and to ensure the 30-second immersion time is strictly followed.
