Question 1Food Safety

A food establishment reports that several employees developed vomiting and diarrhea within hours of eating the same staff meal. Which agent is most strongly suggested by this short incubation period?

  1. Listeria monocytogenes
  2. Cyclospora cayetanensis
  3. Staphylococcus aureus Correct answer.
  4. Hepatitis A virus

Explanation

Staphylococcal food poisoning results from preformed toxin and produces vomiting and diarrhea within roughly 1 to 6 hours of eating the implicated food. Hepatitis A, Cyclospora, and Listeria all have incubation periods measured in days to weeks. The rapid onset after a shared meal is the key clue.

Question 2Food Safety

Under the FDA Food Code, which action is required when a food employee is diagnosed with an infection caused by Salmonella Typhi?

  1. The employee may continue working with gloves and a mask.
  2. The employee may work only in non-food-contact areas.
  3. The employee must be excluded from the food establishment. Correct answer.
  4. The employee may return after a single negative stool test.

Explanation

Typhoid fever is one of the big five reportable illnesses requiring exclusion of the food employee from the establishment. Restriction to non-food duties is not sufficient for this diagnosis. Clearance to return requires approval from the regulatory authority, not a single test.

Question 3Food Safety

Which temperature range is the danger zone in which bacteria multiply most rapidly in potentially hazardous food?

  1. 41°F to 135°F (5°C to 57°C) Correct answer.
  2. 0°F to 32°F (-18°C to 0°C)
  3. 32°F to 41°F (0°C to 5°C)
  4. 135°F to 212°F (57°C to 100°C)

Explanation

The danger zone is defined as 41°F to 135°F, the range in which pathogens multiply fastest in potentially hazardous food. Food should be kept out of this range as much as possible during storage, preparation, and holding.

Question 4Food Safety

A manager is calibrating a bimetallic stemmed thermometer. Which method correctly uses the ice-point procedure?

  1. Insert the stem into a glass of crushed ice and water and adjust to 32°F after 30 seconds. Correct answer.
  2. Place the thermometer in boiling water and adjust to 212°F at sea level.
  3. Insert the stem into the thickest part of a refrigerated food and adjust to 41°F.
  4. Compare the reading to a second thermometer and average the two readings.

Explanation

The ice-point method uses a slurry of crushed ice and water, which is stable at 32°F, and the thermometer is adjusted after the reading stabilizes. Boiling water can also be used but is affected by altitude and is not the ice-point method. Comparing two thermometers does not establish a true reference.

Question 5Food Safety

Which practice best prevents cross-contamination when a food employee handles raw chicken and then prepares a ready-to-eat salad?

  1. Rinsing gloved hands under running water
  2. Wiping hands on a clean apron before continuing
  3. Washing hands and changing gloves, then using clean utensils Correct answer.
  4. Changing gloves without washing hands

Explanation

Raw poultry juices carry pathogens that must not reach ready-to-eat food, so hands must be washed and gloves changed before touching the salad, and clean utensils should be used. Rinsing or wiping gloves does not remove contamination. Gloves are not a substitute for handwashing.

Question 6Food Safety

What is the required final rinse temperature for sanitizing utensils in a stationary rack, single-temperature mechanical hot-water dishwasher?

  1. At least 120°F (49°C)
  2. At least 165°F (74°C)
  3. At least 180°F (82°C) Correct answer.
  4. At least 150°F (66°C)

Explanation

A stationary rack, single-temperature machine must reach a final rinse of at least 180°F to sanitize effectively. Lower rinse temperatures apply to other machine types or to chemical sanitizing. The higher temperature ensures adequate heat sanitizing of the utensils.

Question 7Food Safety

Which food is considered a TCS (time/temperature control for safety) food?

  1. Dry rice in a sealed bag
  2. Whole, uncut apples
  3. Sliced cantaloupe Correct answer.
  4. Whole raw potatoes

Explanation

Cut melons are TCS foods because cutting exposes moist, nutrient-rich flesh that supports pathogen growth. Whole uncut produce and dry staples are generally not TCS foods. The cut surface and moisture are what create the hazard.

Question 8Food Safety

A food handler is diagnosed with a nontyphoidal Salmonella infection but has no symptoms. What does the Food Code require?

  1. Exclusion from the establishment until cleared
  2. Restriction from working with exposed food until cleared Correct answer.
  3. Exclusion only if diarrhea develops
  4. No restrictions if symptoms are absent

Explanation

An asymptomatic food employee with a nontyphoidal Salmonella diagnosis is restricted from working with exposed food, clean equipment, and utensils until cleared. Exclusion is reserved for the big five illnesses and for symptomatic cases. The restriction prevents the employee from contaminating food while allowing other duties.

Question 9Food Safety

A batch of chili is cooked and then cooled for later use. Which cooling schedule meets FDA Food Code requirements?

  1. From 135°F to 41°F within 8 hours in one continuous step
  2. From 135°F to 70°F within 2 hours, then to 41°F within 4 more hours Correct answer.
  3. From 135°F to 70°F within 6 hours, then to 41°F within 2 more hours
  4. From 135°F to 70°F within 4 hours, then to 41°F within 2 more hours

Explanation

The Food Code requires cooling from 135°F to 70°F within 2 hours, then from 70°F to 41°F within an additional 4 hours, for a total of 6 hours. This two-stage schedule limits the time food spends in the danger zone. Other schedules either exceed the first-stage limit or total time.

Question 10Food Safety

Which concentration of chlorine bleach solution is appropriate for sanitizing food-contact surfaces?

  1. 50 ppm Correct answer.
  2. 5 ppm
  3. 500 ppm
  4. 5,000 ppm

Explanation

A chlorine sanitizing solution for food-contact surfaces is typically prepared at about 50 ppm, with the range commonly cited as 50 to 100 ppm. Higher concentrations leave residue and can be unsafe on food-contact surfaces, while much lower levels are ineffective.

Question 11Food Safety

A restaurant receives a shipment of shellstock oysters. Which record must be kept and for how long?

  1. The supplier's business license, for 1 year
  2. The invoice, for 30 days
  3. The shellstock tag, for 90 days from the date the last shellfish was served Correct answer.
  4. A temperature log, for 7 days

Explanation

Shellstock tags must be retained for 90 days from the date the last shellfish from the container is served. Tags allow traceability in case of a shellfish-borne illness outbreak. Invoices and licenses do not substitute for the required tag.

Question 12Food Safety

A food establishment is using time as a public health control for a cold salad bar item. Which practice is required?

  1. The food may be held for up to 8 hours without temperature control.
  2. The food may be returned to refrigeration and reused if it looks acceptable.
  3. The food must be held at 70°F or below during the time period.
  4. The food must be marked with the time it was removed from temperature control and discarded after 4 hours. Correct answer.

Explanation

When time alone is used as the control, food must be marked with the time it left temperature control and discarded within 4 hours if not sold or consumed. Food held this way cannot be returned to refrigeration for later use. The 4-hour limit keeps pathogen growth within acceptable bounds.

Question 13Food Safety

Which set of conditions is required for Clostridium botulinum spores to germinate and produce toxin in food?

  1. High acid, aerobic, and refrigerated
  2. Alkaline, oxygen-rich, and hot-held above 135°F
  3. Low acid, anaerobic, and low-oxygen moisture conditions Correct answer.
  4. High salt, dry, and frozen

Explanation

Clostridium botulinum requires a low-acid, anaerobic environment with sufficient moisture to germinate and produce toxin. High-acid or oxygen-rich conditions inhibit it. This is why low-acid canned and vacuum-packed foods are of particular concern.

Question 14Food Safety

A caterer is transporting hot food to an off-site event. What is the minimum internal temperature the food must be held at during transport?

  1. 135°F (57°C) Correct answer.
  2. 120°F (49°C)
  3. 130°F (54°C)
  4. 145°F (63°C)

Explanation

Hot food must be held at 135°F or above to stay out of the danger zone. Transport does not relax this requirement. Holding below 135°F allows rapid bacterial growth.

Question 15Food Safety

Which organism is most associated with illness from undercooked ground beef?

  1. Bacillus cereus
  2. Vibrio parahaemolyticus
  3. Escherichia coli O157:H7 Correct answer.
  4. Clostridium botulinum

Explanation

Escherichia coli O157:H7 is a well-known hazard in undercooked ground beef and can cause severe bloody diarrhea and hemolytic uremic syndrome. Ground beef must be cooked to 155°F to destroy it. The other organisms are linked to different foods and conditions.

Question 16Food Safety

A food employee has a sore throat and fever but no vomiting or diarrhea. What does the Food Code require?

  1. Restriction from working with exposed food, clean equipment, and utensils Correct answer.
  2. No action, because only gastrointestinal symptoms matter
  3. Exclusion from the establishment until symptoms resolve
  4. Exclusion only if a physician confirms a diagnosis

Explanation

An employee with symptoms such as sore throat with fever, or with vomiting, diarrhea, or jaundice, must be restricted from working with exposed food and clean utensils. Exclusion is reserved for the big five diagnoses and for certain situations. The restriction protects food while allowing other duties.

Question 17Food Safety

Which cooking temperature is required for a whole pork roast?

  1. 155°F (68°C) for 15 seconds
  2. 165°F (74°C) for 15 seconds
  3. 135°F (57°C) for 15 seconds
  4. 145°F (63°C) for 15 seconds Correct answer.

Explanation

Whole cuts of pork, like other whole-muscle meats, must be cooked to 145°F for 15 seconds. Ground pork requires 155°F, and poultry requires 165°F. The distinction between whole cuts and ground meat is the key.

Question 18Food Safety

A manager finds a can of tomatoes with a swollen end. What is the appropriate action?

  1. Chill the can and use it within 24 hours.
  2. Discard the can without opening it. Correct answer.
  3. Return it to the shelf if the label is intact.
  4. Open the can and check for off odors before deciding.

Explanation

A swollen can may indicate gas production from microbial growth, including Clostridium botulinum, and must be discarded without opening or tasting. Opening or smelling a suspect can risks exposure. Swollen cans are never acceptable for use.

Question 19Food Safety

Which practice correctly demonstrates active managerial control of food safety risks?

  1. Relying on employee experience to avoid hazards
  2. Posting handwashing signs in restrooms only
  3. Reviewing inspection reports after violations are cited
  4. Monitoring critical control points and correcting deviations during operations Correct answer.

Explanation

Active managerial control means identifying hazards, establishing controls, and monitoring them in real time with corrective actions when limits are exceeded. It is proactive rather than reactive. Reviewing reports after the fact or relying on experience is not active control.

Question 20Food Safety

A food handler prepares a sandwich and then must handle money at the register. What is the proper practice?

  1. Keep gloves on and handle money, then continue preparing food.
  2. Remove gloves or wash hands before returning to food preparation. Correct answer.
  3. Use hand sanitizer instead of handwashing after handling money.
  4. Wipe gloves with a sanitizing cloth between tasks.

Explanation

Money is a source of contamination, so hands must be washed and gloves removed before returning to food preparation. Gloves worn while handling money must not be used for food. Hand sanitizer is not a substitute for handwashing.

Question 21Food Safety

A food establishment is implicated in an outbreak. Which action best supports an effective traceback investigation?

  1. Discarding all records once the food is sold
  2. Relying on staff memory of suppliers
  3. Maintaining invoices and receiving records for at least 90 days Correct answer.
  4. Recording only the total amount purchased

Explanation

Traceback depends on complete receiving and invoice records that identify the supplier, date, and product, retained for at least 90 days. Detailed records allow investigators to link illness to a source. Discarding records or relying on memory undermines traceback.

Question 22Food Safety

A sous vide product is cooked in a vacuum-sealed pouch. Which consideration is most important for food safety?

  1. The anaerobic environment can favor Clostridium botulinum, so temperature and time controls must be strict. Correct answer.
  2. The pouch prevents all pathogen growth during storage.
  3. Vacuum sealing sterilizes the food during packaging.
  4. Vacuum sealing eliminates the need for temperature control.

Explanation

Vacuum packaging removes oxygen, creating conditions that favor anaerobic pathogens such as Clostridium botulinum. Strict time and temperature controls, including rapid chilling, are essential. Vacuum sealing neither sterilizes food nor removes the need for temperature control.

Question 23Food Safety

A manager must verify that a reduced-oxygen packaged food is safe. Which combination of controls is most appropriate?

  1. Freezing the product after packaging only
  2. Barriers such as pH and water activity plus strict temperature control Correct answer.
  3. Refrigeration alone, with no time limits
  4. Relying on the absence of oxygen to prevent growth

Explanation

Reduced-oxygen packaging requires multiple hurdles, such as pH and water activity barriers combined with strict temperature control, to prevent growth of anaerobic pathogens. Refrigeration alone or the absence of oxygen is not sufficient. Freezing after packaging does not address the hazard during shelf life.

Question 24Food Safety

An establishment wants to use a variance for a special process. Which statement best describes when a variance is required?

  1. Only when the establishment changes ownership
  2. When a process deviates from the Food Code in a way that requires regulatory approval Correct answer.
  3. Whenever a new menu item is added
  4. Whenever employees are retrained

Explanation

A variance is required when a process deviates from the Food Code in a way that needs regulatory approval, such as certain curing, smoking, or specialized processing methods. Adding a routine menu item or retraining staff does not trigger a variance. Approval must come from the regulatory authority.

Question 25Food Safety

A food establishment is developing a HACCP plan. Which step comes immediately after identifying critical control points?

  1. Conduct a hazard analysis
  2. Record corrective actions
  3. Establish critical limits for each CCP Correct answer.
  4. Verify the plan

Explanation

In HACCP, after hazard analysis and identification of critical control points, critical limits are established for each CCP. Hazard analysis precedes CCP identification. Verification and corrective action records come later in the plan.

Question 26Food Safety

A food establishment uses a quaternary ammonium compound to sanitize food-contact surfaces. Which factor most directly determines whether the solution is effective at the time of use?

  1. The color of the sanitizer bucket used to hold the solution
  2. The concentration of the sanitizer and its contact time on the surface Correct answer.
  3. The temperature of the dish machine's final rinse cycle
  4. The number of employees who have completed food handler training

Explanation

Chemical sanitizer effectiveness depends on concentration, contact time, temperature, and pH, with concentration and contact time being the most direct operational controls. A sanitizer used below its labeled concentration or for too short a contact time will not reduce pathogens to safe levels.

Question 27Food Safety

A food employee is preparing a raw chicken dish and then must assemble a ready-to-eat salad for the same order. What is the required hand hygiene step?

  1. Wash hands and exposed arms with soap and warm water before donning new gloves Correct answer.
  2. Change gloves without washing hands first
  3. Wipe hands on a clean cloth towel before continuing
  4. Rinse hands briefly in the sanitizer bucket used for wiping cloths

Explanation

The Food Code requires food employees to wash hands before donning gloves and whenever switching from raw animal foods to ready-to-eat foods. Gloves alone are not a substitute for handwashing, because contamination can pass through or around gloves during removal.

Question 28Food Safety

A food establishment receives a delivery of raw shell eggs. Which receiving condition is acceptable?

  1. Eggs received at an internal temperature of 50°F (10°C) Correct answer.
  2. Eggs with cracked shells that are still cold to the touch
  3. Eggs received at an ambient temperature of 60°F (16°C) with no temperature check
  4. Eggs with visible fecal material on the shell that will be rinsed before use

Explanation

Shell eggs must be received at an ambient air temperature of 45°F (7°C) or less, and the internal temperature should be comparable. Eggs held at 50°F internal during receipt are within acceptable cold-holding range for receiving checks in most jurisdictions.

Question 29Food Safety

A manager is reviewing the establishment's written procedures for cleaning up vomit in the dining room. Which item must the procedure address?

  1. The number of guests present at the time of the incident
  2. The brand of floor cleaner used by the janitorial contractor
  3. The specific pathogen of concern and the concentration of disinfectant effective against it Correct answer.
  4. The color of the disposable gloves worn by the cleaner

Explanation

Vomit and diarrheal incidents require procedures that address norovirus and other pathogens, including use of an EPA-registered disinfectant at a concentration effective against the target organism. The Food Code requires written procedures for employees to follow when responding to such events.

Question 30Food Safety

A food handler in a deli is slicing ready-to-eat roast beef. Which action best prevents cross-contamination from the slicer?

  1. Spraying the blade with a sanitizer and immediately slicing the next product
  2. Rinsing the blade with hot water only between products
  3. Cleaning and sanitizing the slicer at least every 4 hours during continuous use Correct answer.
  4. Wiping the blade with a damp cloth between products

Explanation

Food-contact surfaces used with TCS foods must be cleaned and sanitized at least every 4 hours during continuous operation. Cleaning and sanitizing removes residues and reduces pathogen buildup that could contaminate ready-to-eat foods.

Question 31Food Safety

A restaurant stores raw ground beef above a pan of cooked rice in the walk-in cooler. What is the primary food safety concern?

  1. The beef will lose moisture and dry out
  2. The beef juices may drip onto the rice and contaminate it with pathogens Correct answer.
  3. The cooler will use more energy to maintain temperature
  4. The rice will absorb odors from the beef

Explanation

Raw animal foods must be stored below ready-to-eat foods to prevent drip contamination. Ground beef juices can carry pathogens such as Salmonella and E. coli, and the cooked rice will not receive a kill step before service.

Question 32Food Safety

A food establishment serves a raw fish ceviche dish. Which parasite control is required before the fish is used?

  1. Soaking the fish in vinegar for 30 minutes
  2. Holding the fish at 41°F (5°C) for 24 hours
  3. Rinsing the fish in chlorinated water
  4. Freezing the fish according to a specified time and temperature schedule Correct answer.

Explanation

Fish served raw or undercooked must be frozen to specified time and temperature combinations to kill parasites, unless it is exempt (for example, certain aquacultured fish). Acid marinades and cold holding do not reliably destroy parasites.

Question 33Food Safety

A food establishment's ice machine is used to store ice for beverages. Which practice is acceptable?

  1. Storing ice in a clean, sanitized container dedicated to ice Correct answer.
  2. Storing ice in a container previously used for raw poultry
  3. Using the ice scoop as a hand tool while handling raw meat
  4. Using bare hands to scoop ice into glasses

Explanation

Ice is a food and must be protected from contamination, so it is stored in clean and sanitized containers used only for ice. Scoops must be used, and the scoop handle must not contact the ice.

Question 34Food Safety

A chef is preparing a large batch of chicken noodle soup with chicken, noodles, and broth. What is the minimum internal cooking temperature the chicken must reach?

  1. 145°F (63°C) for 15 seconds
  2. 155°F (68°C) for 17 seconds
  3. 165°F (74°C) for 15 seconds Correct answer.
  4. 135°F (57°C) for 15 seconds

Explanation

Poultry, including chicken in soups, must be cooked to an internal temperature of 165°F (74°C) for 15 seconds. This temperature provides the required lethality for Salmonella and other poultry-associated pathogens.

Question 35Food Safety

A food establishment uses a three-compartment sink to manually wash, rinse, and sanitize utensils. Which sequence is correct?

  1. Sanitize, wash, rinse, then air dry
  2. Wash, rinse, sanitize, then air dry Correct answer.
  3. Wash, sanitize, rinse, then towel dry
  4. Rinse, wash, sanitize, then towel dry

Explanation

Manual warewashing requires washing in detergent, rinsing in clean water, sanitizing in an approved solution, and air drying. Air drying prevents recontamination that can occur when utensils are towel dried.

Question 36Food Safety

A food establishment holds a hot buffet of cooked vegetables at 130°F (54°C). Which corrective action is required?

  1. Leave the vegetables as is because vegetables are not TCS foods
  2. Reheat the vegetables to at least 165°F (74°C) and hold at 135°F (57°C) or above Correct answer.
  3. Add ice to the buffet to cool the vegetables
  4. Discard the vegetables only if they have been held more than 8 hours

Explanation

Hot TCS foods must be held at 135°F (57°C) or above. When food falls below that temperature, it must be reheated to 165°F (74°C) for 15 seconds and returned to proper hot holding, or discarded if time limits are exceeded.

Question 37Food Safety

A food establishment is cooling a large pot of beef stew. Which method best supports rapid cooling?

  1. Leaving the pot on the counter to cool to room temperature before refrigerating
  2. Stacking the hot pot with other hot pots to conserve cooler space
  3. Placing the covered pot in the walk-in cooler with the lid on
  4. Dividing the stew into shallow pans and using an ice bath with stirring Correct answer.

Explanation

Cooling is fastest when food is divided into shallow layers and agitated in an ice bath or otherwise exposed to rapid heat transfer. The Food Code requires cooling from 135°F to 70°F within 2 hours and to 41°F within a total of 6 hours.

Question 38Food Safety

A food handler is diagnosed with an infection caused by Shiga toxin-producing E. coli. What does the Food Code require?

  1. The employee may return after 24 hours without symptoms
  2. The employee may work if gloves are worn and symptoms are mild
  3. The employee may work only in non-food-contact areas such as dishwashing
  4. The employee must be excluded from the food establishment and reported to the regulatory authority Correct answer.

Explanation

Employees diagnosed with an infection from Shiga toxin-producing E. coli, Salmonella Typhi, Shigella, or hepatitis A must be excluded and the illness reported to the regulatory authority. Return to work requires clearance under the Food Code's provisions.

Question 39Food Safety

A food establishment purchases a reduced-oxygen packaged (ROP) fish product. Which control is most important for safety?

  1. Relying on the vacuum seal to prevent all bacterial growth
  2. Removing the packaging immediately upon receipt and storing the fish uncovered
  3. Maintaining continuous temperature control and monitoring for time-temperature abuse Correct answer.
  4. Storing the product at room temperature to preserve texture

Explanation

Reduced-oxygen packaging can support growth of anaerobic pathogens such as Clostridium botulinum and Listeria, so strict temperature control and monitoring are essential. The Food Code requires records and controls for ROP foods.

Question 40Food Safety

A manager is conducting a hazard analysis for a new menu item that includes raw sprouts. Which hazard is of greatest concern?

  1. Radiological hazard from irrigation water
  2. Chemical hazard from sprout seed coatings
  3. Physical hazard from sprout hulls
  4. Biological hazard from Salmonella and E. coli associated with sprouts Correct answer.

Explanation

Raw sprouts are a known vehicle for Salmonella and E. coli because the warm, humid sprouting environment supports pathogen growth. The Food Code addresses sprout seed treatment and sprout irrigation water testing as controls.

Question 41Food Safety

A food establishment wants to use time as a public health control for hot-held cooked chicken. Which requirement applies?

  1. The food must be reheated every 2 hours to 165°F
  2. The food may be held up to 8 hours without temperature control if it starts at 135°F
  3. The food must be marked with the time it was removed from temperature control and discarded within 4 hours Correct answer.
  4. The food may be held indefinitely if it is covered

Explanation

When time is used as a public health control, the food must be marked or otherwise identified with the time it was removed from temperature control and must be discarded within 4 hours (or 6 hours if starting at 41°F and not exceeding 70°F).

Question 42Food Safety

A food establishment is located in a building where the water supply is temporarily interrupted. What is the most appropriate immediate action?

  1. Cease operations or restrict operations until an adequate potable water supply is restored Correct answer.
  2. Use water from a nearby pond after boiling
  3. Continue operations using bottled water for drinking only
  4. Continue operations and document the interruption in the log

Explanation

An adequate supply of potable water is required for handwashing, warewashing, and food preparation. If the supply is interrupted, the establishment must cease or restrict operations until potable water is restored.

Question 43Food Safety

A food establishment uses a private water well. Which testing requirement applies?

  1. No testing is required if the well is deeper than 100 feet
  2. The water must be tested annually for total coliform bacteria Correct answer.
  3. The water must be tested every five years for nitrates
  4. The water must be tested only when a customer complains

Explanation

Private water supplies must be sampled and tested at least annually for total coliform bacteria and, when required, for other contaminants. The results must be retained and made available to the regulatory authority.

Question 44Food Safety

A food establishment is preparing to vacuum-package cooked beef for refrigerated storage. Which combination of controls is most appropriate?

  1. Freezing the product before vacuum packaging and holding at 41°F
  2. Relying on the vacuum seal to prevent pathogen growth
  3. Using a HACCP plan with time-temperature controls, validated cooling, and Listeria controls Correct answer.
  4. Adding vinegar to the product and storing at 50°F

Explanation

Reduced-oxygen packaging of cooked foods requires a HACCP plan or variance with validated controls for anaerobic pathogens, including Clostridium botulinum and Listeria monocytogenes. Cooling, storage temperature, and shelf-life limits must be validated.

Question 45Food Safety

A food establishment is implicated in a foodborne illness outbreak. Which action best supports an effective traceback investigation?

  1. Contacting the media before the regulatory authority
  2. Relying on employee memory of the day's deliveries
  3. Maintaining receiving records, lot codes, and distribution records for foods Correct answer.
  4. Discarding all suspect food immediately without records

Explanation

Traceback depends on accurate records that link a finished product to its source, including receiving documents, lot codes, and distribution records. Retaining these records allows investigators to identify the contaminated lot and prevent further illness.

Question 46Food Safety

A food establishment proposes to cure meat using a process that does not require refrigeration for safety. Which statement best describes when a variance is required?

  1. A variance is required when the establishment proposes to use a process that the Food Code does not otherwise prescribe Correct answer.
  2. A variance is required whenever the establishment changes suppliers
  3. A variance is required whenever a new menu item is added
  4. A variance is required only when a customer requests it

Explanation

A variance is required when an establishment proposes to use a food process that is not otherwise prescribed by the Food Code, such as certain curing, smoking, or reduced-oxygen packaging methods. The regulatory authority must approve the variance and any HACCP plan.

Question 47Food Safety

A food establishment is evaluating whether a process is under active managerial control. Which evidence best demonstrates that control?

  1. Employee statements that they always follow procedures
  2. Monitoring records showing critical limits met, with corrective actions documented Correct answer.
  3. A written policy posted in the office
  4. A certificate of insurance from the property owner

Explanation

Active managerial control is demonstrated by monitoring and records showing that critical limits are consistently met and that deviations are corrected. Written policies alone do not prove that controls are operating.

Question 48Food Safety

A food establishment is using a molluscan shellfish tank to hold live shellfish. Which practice is required?

  1. Using the tank water for drinking water
  2. Maintaining water quality and records of tank cleaning and shellfish source Correct answer.
  3. Holding the shellfish at room temperature between shifts
  4. Storing the shellfish with raw poultry to save space

Explanation

Live shellfish held in tanks require approved water quality, cleaning records, and documentation of the shellfish source. Shellstock tags must be retained for 90 days from the date the container is emptied.

Question 49Food Safety

A food establishment is reviewing its employee health policy. Which symptom requires exclusion of a food employee?

  1. A seasonal allergy with sneezing
  2. A minor cut on the finger covered with a bandage
  3. A mild headache without other symptoms
  4. Vomiting, diarrhea, or jaundice Correct answer.

Explanation

Food employees with vomiting, diarrhea, or jaundice must be excluded from the establishment because these symptoms suggest pathogens such as norovirus or hepatitis A. A covered cut on a finger is managed with a bandage and glove rather than exclusion.

Question 50Food Safety

A food establishment uses a hot water sanitizing dish machine. Which condition must be met for sanitizing?

  1. The machine must use a chemical sanitizer in addition to hot water
  2. The final rinse must reach at least 180°F (82°C) at the manifold for a stationary rack machine Correct answer.
  3. The final rinse must last at least 30 seconds
  4. The wash water must reach 120°F (49°C)

Explanation

Hot water sanitizing in a stationary rack, single-temperature machine requires a final rinse of at least 180°F (82°C) at the manifold. The temperature must be measured and recorded to verify sanitizing.
