The three-compartment sink is the standard for manual warewashing in a professional kitchen. According to the FDA Food Code and ServSafe guidelines, the first sink is dedicated to washing. The water in this compartment must be at a minimum temperature of $110^{\circ}F$ ($43^{\circ}C$). This specific temperature is required because it is the threshold at which most commercial detergents become effective at breaking down food fats and greases. If the water is too cold, the detergent will not emulsify the grease, leaving a film on the dishes that prevents the sanitizer in the third sink from working effectively.

Managers must ensure that the sink is equipped with a thermometer to monitor the temperature throughout the cleaning process. If the water temperature drops below $110^{\circ}F$, it must be drained and refilled. The wash sink must also contain a detergent solution that is changed frequently to prevent the buildup of organic soil. For comparison, $171^{\circ}F$ (Option C) is the minimum temperature required for heat-based sanitizing in the third compartment if chemicals are not used, and $180^{\circ}F$ (Option D) is the required temperature for the final sanitizing rinse in a high-temperature commercial dishwasher. The $110^{\circ}F$ requirement for the first sink balances the need for chemical activation with the safety of the employee, as higher temperatures could cause burns during manual scrubbing. Maintaining this temperature is a critical "Active Managerial Control" point to ensure that the initial cleaning phase of warewashing is performed correctly, setting the stage for successful rinsing and sanitizing.

Proper waste-water disposal is essential for preventing cross-contamination and environmental hazards. According to the ServSafe Manager curriculum and the FDA Food Code, all "grey water" or dirty water resulting from floor cleaning must be disposed of in aservice sink(also known as a mop sink or utility sink). These sinks are specifically designed with deep basins and often have a floor-level drain or a high-back splash guard to prevent the spray of contaminated water onto surrounding surfaces.

Disposing of mop water in a toilet (Option A) is unhygienic and can lead to splashing on surfaces that people touch. Dumping water outside (Option C) is often illegal under local environmental codes and can attract pests to the exterior of the building. Using a three-compartment sink (Option D), which is reserved for cleaning and sanitizing food-contact equipment, is a major health code violation that directly causes cross-contamination. Mop water is filled with dirt, grease, and potentially harmful microorganisms likeListeriathat thrive on floors. By using a dedicated service sink, the operation ensures that these contaminants are kept entirely separate from food-prep and warewashing areas. Additionally, the service sink should be equipped with a backflow prevention device (such as an air gap or vacuum breaker) to protect the facility's clean water supply from being contaminated by the dirty water in the sink.

This scenario describes a key component of aHACCP (Hazard Analysis Critical Control Point)system. In food safety management, a "Critical Limit" is a specific value—such as a temperature—that must be met to prevent, eliminate, or reduce a hazard to an acceptable level. For hot-held soup, the critical limit is $135^{\circ}F$ ($57^{\circ}C$) or higher. When the cook discovers the soup is at $130^{\circ}F$, they have identified a "deviation" from the critical limit.

Taking a corrective actionis the step taken when a critical limit is not met. Reheating the soup to $165^{\circ}F$ for 15 seconds (provided the soup has not been in the danger zone for more than two hours) is the approved corrective action to kill any bacteria that may have started to grow while the temperature was too low. Performing a hazard analysis (Option B) happens during the planning phase of HACCP, and establishing a critical limit (Option C) is the act of setting the $135^{\circ}F$ rule in the first place. Verification (Option D) would involve a manager checking the logs later to ensure the cook actually took the measurement and the action. Corrective actions must be documented in a log to show that the "Active Managerial Control" system is working. If the soup had been below $135^{\circ}F$ for more than four hours, the corrective action would be to discard the food entirely. This process ensures that errors are caught and fixed before they can cause a foodborne illness outbreak.

A disruption in the water supply is considered animminent health hazard. Because water is essential for handwashing, cooking, and sanitizing, an establishment cannot operate safely without a potable (drinkable) source. According to the ServSafe Manager curriculum, if the municipal supply fails, the only acceptable short-term alternative5for drinking and food preparation iscommercially bottled drinking waterfrom an approved source.

Other options are highly unsafe: a 50-50 bleach mixture (Option B) is toxic and would cause chemical poisoning. Private wells (Option C) must be tested at least annually, not every two years, and may not be sufficient during a disaster. Water from an air conditioning system (Option D) is non-potable and potentially contaminated with mold and chemicals. If an establishment uses bottled water, it must also address other needs, such as using single-service (disposable) plates and utensils to avoid the need for dishwashing and providing portable handwashing stations or hand sanitizer (though the latter is only a temporary measure). If safe water cannot be secured for all essential tasks, including restroom use and handwashing, the manager must close the operation until the water supply is restored and cleared by the regulatory authority.

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.

Single-use gloves serve as a critical barrier between the food handler’s hands andready-to-eat (RTE) food. According to the FDA Food Code, gloves must be worn whenever a food handler is touching RTE food with their bare hands. While carrots may eventually be cooked, "raw carrots" are often served as sticks or in salads without further cooking. Even if they are to be cooked later, the standard practice in a professional kitchen is to use gloves when preparing fresh produce to minimize the introduction of pathogens.

The other activities listed—taking out trash (Option A), opening a cooler (Option B), and receiving a delivery (Option C)—do not involve direct contact with exposed RTE food. In fact, wearing gloves for these tasks can lead to a false sense of security and actually increase the risk of cross-contamination if the handler then touches food without changing them. The correct sequence for applying gloves is: (1) Wash hands thoroughly, (2) Select the correct glove size, (3) Pull them on, and (4) Check for rips or tears. Gloves must be changed at least every four hours, when switching tasks, or if they become soiled or torn. By applying gloves specifically for "handling raw carrots," the food handler ensures that no pathogens from their skin or environment are transferred to a product that a guest may consume raw.

The use of single-use gloves is a fundamental requirement when handlingready-to-eat (RTE) food. Deli meat is classified as an RTE food because it has already been cooked or processed and requires no further heating to be safe for consumption. According to the ServSafe Manager curriculum and the FDA Food Code, bare-hand contact with RTE food is strictly prohibited (with very few exceptions) because the hands can easily transmit pathogens likeNorovirus,Hepatitis A, orSalmonella Typhi.

When making a cold sandwich, the deli meat is handled directly before being served to the guest. Wearing gloves provides a critical barrier that prevents the transfer of microorganisms from the skin to the food. Washing vegetables (Option A) is a preparation step where gloves are often not required because the water and mechanical action assist in cleaning, and the vegetables may be further processed. Pouring beverages (Option B) and serving plates (Option C) are service tasks where the hands do not typically make direct contact with the food itself. It is vital to remember that gloves are not a substitute for handwashing; a food handler must wash their hands thoroughly before putting on a new pair of gloves. Furthermore, gloves must be changed if they become torn, dirty, or when switching between different tasks (such as moving from raw meat to deli meat). Managers must ensure that staff understand that the primary purpose of gloves in this context is to protect the consumer from "hand-to-food" contamination.
