Question 1Food safety domains per NRFSP exam blueprint (not enumerated in source)

What is the minimum internal cooking temperature for poultry, including whole birds and ground chicken?

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

Explanation

Poultry must reach 165°F (74°C) for at least 15 seconds because Salmonella and Campylobacter are common contaminants and the meat is often handled heavily. This temperature is the highest of the standard minimum cooking temperatures and applies to whole birds, parts, and ground poultry.

Question 2Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler has a cut on the hand. What is the correct way to protect the food while continuing to work?

  1. Wash it and continue bare-handed
  2. Wrap it in a cloth towel
  3. Cover it with a bandage and a single-use glove Correct answer.
  4. Apply ointment and work bare-handed

Explanation

A wound must be completely covered with an impermeable bandage and then a single-use glove to prevent blood and pathogens from contacting food. A bandage alone can fall off, and bare-handed work is never allowed on exposed food.

Question 3Food safety domains per NRFSP exam blueprint (not enumerated in source)

Which practice correctly prevents cross-contamination in a refrigerator?

  1. Storing raw poultry below ready-to-eat foods Correct answer.
  2. Storing raw poultry above salad greens
  3. Storing raw meat uncovered on the top shelf
  4. Storing raw fish next to cut melons

Explanation

Raw animal foods must be stored below ready-to-eat foods so drips cannot contaminate them. Within the raw group, poultry is stored on the lowest shelf because it requires the highest cooking temperature.

Question 4Food safety domains per NRFSP exam blueprint (not enumerated in source)

What is the correct handwashing procedure for a food employee?

  1. Apply soap to dry hands, rinse, dry
  2. Wet hands, scrub 3 seconds, dry
  3. Rinse hands, dry with a towel, apply sanitizer
  4. Wet hands, apply soap, scrub 10–15 seconds, rinse, dry Correct answer.

Explanation

Hands must be wetted, soaped, scrubbed for at least 10–15 seconds, rinsed under running water, and dried with a single-use towel. Scrubbing time and the use of running water are both required to physically remove pathogens.

Question 5Food safety domains per NRFSP exam blueprint (not enumerated in source)

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

  1. Whole raw potatoes
  2. Cooked rice Correct answer.
  3. Dry pasta
  4. Whole uncut apples

Explanation

Cooked rice is moist, low-acid, and has been heat-treated, so it supports rapid bacterial growth and is a TCS food. Uncut whole produce and dry pasta are not TCS because they lack the moisture or available water bacteria need.

Question 6Food safety domains per NRFSP exam blueprint (not enumerated in source)

What is the required final rinse temperature for a high-temperature dishwashing machine?

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

Explanation

High-temperature machines must reach a final rinse of at least 180°F (82°C) at the manifold to sanitize dishes. Lower temperatures do not reliably sanitize without a chemical sanitizer.

Question 7Food safety domains per NRFSP exam blueprint (not enumerated in source)

Which symptom requires a food employee to be excluded from the operation?

  1. A stuffy nose
  2. Vomiting and diarrhea Correct answer.
  3. A small bruise
  4. A mild headache

Explanation

Vomiting and diarrhea are symptoms of foodborne illness that require exclusion from the food operation until cleared. Headache, congestion, and bruises are not foodborne-illness symptoms.

Question 8Food safety domains per NRFSP exam blueprint (not enumerated in source)

Which of these is an example of a physical contaminant?

  1. Mold on bread
  2. A virus on a cutting board
  3. Cleaning chemical residue on a plate
  4. A piece of glass in a salad Correct answer.

Explanation

Physical contaminants are foreign objects such as glass, metal, or bone that enter food and can cause injury. Chemicals, molds, and viruses are categorized as chemical or biological hazards.

Question 9Food safety domains per NRFSP exam blueprint (not enumerated in source)

A pot of soup is being hot-held. At what minimum temperature must it be maintained?

  1. 100°F (38°C)
  2. 145°F (63°C)
  3. 135°F (57°C) Correct answer.
  4. 120°F (49°C)

Explanation

Hot TCS foods must be held at 135°F (57°C) or above to prevent bacterial growth. Temperatures below this enter the temperature danger zone.

Question 10Food safety domains per NRFSP exam blueprint (not enumerated in source)

How often should a food employee change gloves when working with ready-to-eat food?

  1. Once per shift
  2. Every 8 hours
  3. At least every 4 hours and whenever they become soiled Correct answer.
  4. Only when they tear

Explanation

Single-use gloves must be changed at least every 4 hours when continuously working with ready-to-eat food, and sooner if soiled or torn. Gloves are not a substitute for handwashing and must be changed after tasks that could contaminate them.

Question 11Food safety domains per NRFSP exam blueprint (not enumerated in source)

A caterer is cooling a large batch of chili. Which method meets the two-stage cooling requirement?

  1. Cool from 135°F to 70°F within 6 hours, then to 41°F within 2 hours
  2. Cool from 135°F to 41°F within 12 hours
  3. Cool from 135°F to 41°F within 4 hours
  4. Cool from 135°F to 70°F within 2 hours, then to 41°F within 6 more hours Correct answer.

Explanation

TCS foods must be cooled from 135°F to 70°F within 2 hours and then to 41°F within an additional 4 hours (6 hours total). This two-stage approach keeps the food out of the danger zone as quickly as possible.

Question 12Food safety domains per NRFSP exam blueprint (not enumerated in source)

What is the correct concentration for a chlorine sanitizing solution used on food-contact surfaces?

  1. 500–1000 ppm
  2. 2000 ppm
  3. 10–20 ppm
  4. 50–100 ppm Correct answer.

Explanation

A chlorine sanitizer should be mixed to about 50–100 ppm for food-contact surfaces, verified with test strips. Too weak a solution will not sanitize, and too strong a solution can leave harmful residue.

Question 13Food safety domains per NRFSP exam blueprint (not enumerated in source)

A delivery of raw shell eggs arrives. What should the receiving employee check?

  1. That they are cracked but refrigerated
  2. That they are clean, uncracked, and received at 41°F or below Correct answer.
  3. That they are warm to the touch
  4. That they are stored with raw poultry

Explanation

Shell eggs must be clean, uncracked, and received at an internal temperature of 41°F (5°C) or below. Cracked or warm eggs indicate poor handling and should be rejected.

Question 14Food safety domains per NRFSP exam blueprint (not enumerated in source)

What is the correct way to calibrate a bimetallic stemmed thermometer using the ice-point method?

  1. Leave it at room temperature and adjust to 70°F
  2. Place it in a refrigerator and adjust to 41°F
  3. Insert the stem into boiling water and adjust to 212°F
  4. Insert the stem into an ice-water slurry and adjust to 32°F Correct answer.

Explanation

The ice-point method uses a slurry of crushed ice and water, which is stable at 32°F (0°C), and the thermometer is adjusted to that reading. Boiling water can also be used but is less reliable at high altitudes.

Question 15Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler must wash hands before which of the following activities?

  1. Sweeping the floor
  2. Beginning work with ready-to-eat food after handling raw meat Correct answer.
  3. Putting on a clean apron
  4. Taking out the trash

Explanation

Hands must be washed after handling raw animal foods and before touching ready-to-eat food to prevent cross-contamination. Washing is required whenever hands may have become contaminated.

Question 16Food safety domains per NRFSP exam blueprint (not enumerated in source)

What is the minimum internal cooking temperature for ground beef?

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

Explanation

Ground beef must reach 155°F (68°C) for at least 17 seconds because grinding distributes surface bacteria throughout the meat. Whole-muscle beef has a lower minimum because bacteria stay on the surface.

Question 17Food safety domains per NRFSP exam blueprint (not enumerated in source)

How should a food employee with jaundice be managed?

  1. Restricted to dishwashing
  2. Excluded from the operation and referred to a health practitioner Correct answer.
  3. Allowed to work with gloves only
  4. Allowed to work if symptom-free for one hour

Explanation

Jaundice indicates possible hepatitis A or another serious infection and requires exclusion plus referral to a health practitioner. The employee may not return without medical clearance.

Question 18Food safety domains per NRFSP exam blueprint (not enumerated in source)

Which of these is the correct order of steps for cleaning and sanitizing a food-contact surface?

  1. Rinse, scrape, sanitize, wash
  2. Scrape, sanitize, wash, rinse, towel-dry
  3. Wash, sanitize, rinse, air-dry
  4. Scrape, wash, rinse, sanitize, air-dry Correct answer.

Explanation

The correct sequence is to scrape or remove food, wash with detergent, rinse, apply sanitizer, and air-dry. Air-drying prevents recontamination that towel-drying can cause.

Question 19Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment uses a quaternary ammonium sanitizer. What must be done to ensure it works?

  1. Verify the concentration with test strips and follow the label contact time Correct answer.
  2. Mix it with chlorine to increase strength
  3. Use it at any concentration
  4. Apply it to a wet, soiled surface

Explanation

Sanitizers must be mixed to the label concentration, verified with the appropriate test strips, and left on the surface for the labeled contact time. Mixing sanitizers can create dangerous reactions and is prohibited.

Question 20Food safety domains per NRFSP exam blueprint (not enumerated in source)

What is the required minimum internal temperature for reheating a TCS food that was cooked and cooled?

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

Explanation

Previously cooked and cooled TCS food must be reheated to 165°F (74°C) for 15 seconds within 2 hours before hot-holding. This destroys bacteria that may have grown during cooling and storage.

Question 21Food safety domains per NRFSP exam blueprint (not enumerated in source)

A manager notices that a cold-holding display case is reading 45°F. What is the appropriate response?

  1. Leave the food and lower the thermostat later
  2. Discard all food immediately without evaluation
  3. Move the food to a unit at 41°F or below and evaluate its safety Correct answer.
  4. Add ice to the case and continue selling the food

Explanation

Food held above 41°F is in the danger zone and must be moved to proper cold holding while its time and temperature history is evaluated. Food that has been above 41°F for more than 4 hours must be discarded.

Question 22Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food employee reports that they were diagnosed with Salmonella infection. When may they return to work?

  1. After medical clearance and approval by the regulatory authority Correct answer.
  2. After 24 hours without symptoms
  3. After taking antibiotics for one day
  4. Immediately if they wear gloves

Explanation

Employees diagnosed with Salmonella, E. coli, or hepatitis A must be excluded and may return only with medical clearance and regulatory approval. Symptom improvement alone does not ensure the person is no longer shedding the pathogen.

Question 23Food safety domains per NRFSP exam blueprint (not enumerated in source)

A buffet uses time as a public health control for a TCS food. What is the maximum time the food may be held before it must be discarded?

  1. 2 hours
  2. 8 hours
  3. 6 hours
  4. 4 hours Correct answer.

Explanation

When time rather than temperature is used as the control, the food may be held for a maximum of 4 hours from the time it leaves temperature control, then it must be discarded. The food must be marked with the time it was removed from temperature control.

Question 24Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler is preparing a large batch of ground beef patties and must check the internal temperature. Where should the thermometer be inserted?

  1. Into the thinnest edge of the patty
  2. Into the center of the grill surface
  3. Into the thickest part of the patty, avoiding fat and bone Correct answer.
  4. Into the fat drippings

Explanation

The probe must be inserted into the thickest part of the food, away from fat, bone, and gristle, because those areas heat differently and can give a false reading. The coldest point determines whether the food has reached the required temperature.

Question 25Food safety domains per NRFSP exam blueprint (not enumerated in source)

A vacuum-packaged fish is received and shows signs of a broken seal and a slimy texture. What should the receiver do?

  1. Accept it and use it in a salad
  2. Accept it and freeze it immediately
  3. Reject the delivery and document the reason Correct answer.
  4. Accept it and cook it thoroughly

Explanation

A broken vacuum seal and slimy texture indicate temperature abuse or spoilage, so the delivery must be rejected and the reason documented. Vacuum-packed fish also carries a risk of botulism if the seal is compromised.

Question 26Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food employee is diagnosed with an infection caused by Shigella spp. According to FDA Food Code guidance, what action must the person in charge take?

  1. Allow the employee to work if gloves are worn at all times
  2. Exclude the employee from the food establishment and notify the regulatory authority Correct answer.
  3. Restrict the employee to non-food-contact duties until symptoms resolve
  4. Require the employee to submit a stool sample before returning to any duty

Explanation

Shigella spp. is one of the big-six pathogens that triggers exclusion of a food employee from the establishment, along with a requirement to report the diagnosis to the regulatory authority. Restriction alone is insufficient because the risk of transmission is high. The employee may return only when approved by the regulatory authority and symptom-free for the required period.

Question 27Food safety domains per NRFSP exam blueprint (not enumerated in source)

A cook is measuring the internal temperature of a roast on a buffet line and wants the most accurate reading of the center. Which practice should be used?

  1. Insert the probe into the thickest part and wait for the reading to stabilize Correct answer.
  2. Insert the probe near the surface where the food cools fastest
  3. Use an infrared thermometer aimed at the top surface of the roast
  4. Take the reading immediately after inserting the probe and record it

Explanation

The probe should be placed in the thickest part, which is the slowest-heating point and therefore the coldest spot in a cooked item. The temperature must be allowed to stabilize so the sensor equilibrates with the food. Surface or infrared readings do not reflect the internal temperature of the mass.

Question 28Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment wants to use a chemical sanitizer at a concentration higher than the label maximum to ensure effectiveness. What should the person in charge do?

  1. Increase the concentration, since stronger solutions always sanitize more effectively
  2. Use the higher concentration and skip the final potable water rinse
  3. Follow the label use concentration, because exceeding it is not permitted and may leave residues Correct answer.
  4. Double the concentration only for raw animal food contact surfaces

Explanation

Sanitizer concentration must fall within the range specified on the EPA-registered label; exceeding it does not improve safety and can leave harmful residues on food-contact surfaces. Higher concentrations can also be toxic and may corrode equipment. The correct approach is to prepare the solution at the labeled concentration and verify it with test strips.

Question 29Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler notices a can on the shelf with a deep dent along the side seam. What is the appropriate action?

  1. Discard the can or return it to the supplier because the seam may be compromised Correct answer.
  2. Place the can at the front of the shelf for first use
  3. Wipe the can and store it with other canned goods
  4. Use the can if the contents smell normal when opened

Explanation

Dents that affect the side seam or rim can compromise the hermetic seal and allow contamination or pathogen growth, so the can must not be used. Dented cans should be segregated and either discarded or returned to the supplier. A normal smell does not prove the seal is intact.

Question 30Food safety domains per NRFSP exam blueprint (not enumerated in source)

Which circumstance requires a food employee to be restricted from working with exposed food, clean equipment, and utensils?

  1. The employee has seasonal allergies with sneezing controlled by medication
  2. The employee has a healed scar on the forearm
  3. The employee has a mild headache with no other symptoms
  4. The employee has a lesion containing pus on an exposed body part Correct answer.

Explanation

A lesion containing pus on an exposed body part such as the hand or wrist requires restriction, and the lesion must be covered with an impermeable bandage and a single-use glove. Restriction keeps the employee away from exposed food and clean food-contact surfaces. Non-infectious conditions such as scars or allergies do not require restriction.

Question 31Food safety domains per NRFSP exam blueprint (not enumerated in source)

A manager is setting up a three-compartment sink for manual warewashing. In what order should the compartments be used?

  1. Wash, rinse, sanitize Correct answer.
  2. Rinse, wash, sanitize
  3. Wash, sanitize, rinse
  4. Sanitize, wash, rinse

Explanation

Manual warewashing uses the sequence of washing in detergent, rinsing in clean water, then sanitizing in the third compartment. The sanitized items are then air-dried. Reversing the order would leave detergent residue or allow recontamination after sanitizing.

Question 32Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment receives a shipment of frozen shrimp that has large ice crystals and water stains on the packaging. What does this indicate and what should be done?

  1. A sign of proper freezing; accept and store immediately
  2. Excess moisture from the supplier's rinse; accept but use first
  3. Possible thawing and refreezing; reject the shipment Correct answer.
  4. Normal frost from cold transport; accept the shipment

Explanation

Large ice crystals and water stains suggest the product thawed and was refrozen, which can allow pathogen growth and degrade quality. Frozen food should be received frozen solid with no evidence of temperature abuse. The shipment should be rejected and documented.

Question 33Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food employee is preparing a salad with cut leafy greens. Which practice best prevents cross-contamination?

  1. Wipe the knife on a cloth towel and continue with the greens
  2. Use a separate clean cutting board and utensils dedicated to ready-to-eat food Correct answer.
  3. Rinse the cutting board with water between raw chicken and salad preparation
  4. Prepare the salad first and raw chicken afterward on the same board

Explanation

Ready-to-eat foods such as cut leafy greens must be prepared with clean, sanitized equipment that has not contacted raw animal foods. Separate color-coded boards and utensils reduce the risk of pathogen transfer. A water rinse or cloth wipe does not remove pathogens from a contaminated surface.

Question 34Food safety domains per NRFSP exam blueprint (not enumerated in source)

An establishment holds sliced melon on a self-service bar without temperature control. Which condition must be met to use time as a public health control?

  1. The food must be reheated to 165°F before each service period
  2. The food must be marked with the time it was removed from temperature control and discarded after 4 hours Correct answer.
  3. The food must be held no longer than 8 hours if the temperature never exceeds 70°F
  4. The food must be covered and stirred every 2 hours

Explanation

When time rather than temperature is used as a public health control, the food must be marked with the time it was removed from temperature control and must be discarded within 4 hours. The written procedure must be approved and kept on file. Reheating or stirring does not extend the 4-hour limit.

Question 35Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler is assigned to clean and sanitize a prep table after working with raw poultry. Which step is essential before applying sanitizer?

  1. Wipe the surface with a dry towel only
  2. Apply sanitizer directly over the poultry juices
  3. Remove visible soil by washing with detergent and rinsing with clean water Correct answer.
  4. Spray sanitizer and immediately dry with a cloth

Explanation

Organic matter such as poultry juices interferes with sanitizer efficacy, so surfaces must first be cleaned with detergent and rinsed before sanitizing. Sanitizer applied over soil will be neutralized and fail to reduce pathogens. Air-drying after sanitizing is also required.

Question 36Food safety domains per NRFSP exam blueprint (not enumerated in source)

A manager is reviewing a HACCP plan for a cook-chill operation. Which element is required to verify that the plan is working?

  1. Monitoring records reviewed and signed by a trained individual at scheduled intervals Correct answer.
  2. A list of employee birthdays and shift schedules
  3. A menu rotation chart for seasonal items
  4. A customer satisfaction survey conducted quarterly

Explanation

Verification in a HACCP plan includes reviewing monitoring records, calibration logs, and corrective action documentation to confirm the system is functioning as designed. Records must be reviewed by a trained individual at defined frequencies. Menu rotation and customer surveys are not verification activities.

Question 37Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment uses a hot-water sanitizing step for utensils. Which condition must be met?

  1. Utensils must be immersed in water at least 171°F for at least 30 seconds Correct answer.
  2. Utensils must be sprayed with water at 150°F for 1 minute
  3. Utensils must be rinsed in water at least 120°F for 10 seconds
  4. Utensils must be soaked in water at 140°F for 5 minutes

Explanation

Hot-water sanitizing requires immersion in water at a minimum of 171°F for at least 30 seconds, or the equivalent contact time using a dish machine's final rinse. Lower temperatures and shorter times do not achieve the required pathogen reduction. The utensils should then be air-dried.

Question 38Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food employee has a cut on the hand that is bandaged with an impermeable cover. What additional step is required before the employee handles food?

  1. Apply a second cloth bandage over the first
  2. Wash the bandage with sanitizer before work
  3. No additional step is required if the bandage is secure
  4. Wear a single-use glove over the bandage Correct answer.

Explanation

A bandage on the hand or wrist must be covered with an impermeable cover and then a single-use glove when the employee works with food. This creates a barrier against blood and wound contamination. Cloth bandages alone are not acceptable.

Question 39Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment is located in an area served by a private water supply. What must be done to ensure the water is safe?

  1. The water must be filtered through a carbon cartridge
  2. The water must be chlorinated to 50 ppm before use
  3. The water must be tested at least annually and meet drinking water standards Correct answer.
  4. The water must be boiled before use in food preparation

Explanation

Private water supplies must be tested at least annually and meet the standards for drinking water; records of testing must be retained. Boiling, carbon filtration, or arbitrary chlorination does not substitute for verified potability. Water used for food, ice, and handwashing must be potable.

Question 40Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler is preparing sushi rice that will be held at room temperature for service. Which control is appropriate?

  1. Acidify the rice to a pH of 4.6 or below as part of a documented procedure Correct answer.
  2. Add preservatives and hold for up to 8 hours
  3. Cover the rice tightly and hold for up to 6 hours
  4. Hold the rice at 50°F and stir it every hour

Explanation

Sushi rice is a TCS food when held at room temperature; acidification to pH 4.6 or below can be used as a documented barrier to pathogen growth. Alternatively, time as a public health control with a 4-hour limit may be used. Holding at 50°F or adding unspecified preservatives is not an approved control.

Question 41Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food employee is assigned to wash dishes and also to prepare food. Which practice is required to prevent contamination between tasks?

  1. Wipe hands on a clean towel and continue working
  2. Change gloves only if they appear visibly soiled
  3. Rinse hands in sanitizer before handling food
  4. Wash hands and change to clean apron or outer clothing before returning to food preparation Correct answer.

Explanation

When moving from warewashing or other dirty tasks to food preparation, employees must wash hands and change soiled outer clothing or aprons that could transfer contamination. Hand sanitizer does not replace handwashing. Gloves must be changed when soiled or when switching tasks.

Question 42Food safety domains per NRFSP exam blueprint (not enumerated in source)

A manager is evaluating a new employee who will handle food. Which information must be gathered during the food safety orientation?

  1. The employee's transportation schedule
  2. The employee's health status and foodborne illness symptoms reporting responsibilities Correct answer.
  3. The employee's favorite foods and dining preferences
  4. The employee's previous employers' menu items

Explanation

Food employees must be informed of their responsibility to report health conditions and symptoms associated with foodborne illness, such as vomiting, diarrhea, jaundice, and diagnosed infections. This reporting duty is a core part of the food safety orientation. Menu items and personal preferences are irrelevant.

Question 43Food safety domains per NRFSP exam blueprint (not enumerated in source)

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

  1. Divide the stew into shallow pans and place it in a blast chiller or ice bath Correct answer.
  2. Leave the stew in the original deep pot at room temperature
  3. Cover the pot tightly and place it in a warm area
  4. Add ice directly to the stew and stir occasionally

Explanation

Cooling is accelerated by increasing surface area and using a blast chiller, ice bath, or shallow pans no more than 4 inches deep. The food must reach 70°F within 2 hours and 41°F within a total of 6 hours. Leaving food in a deep pot or a warm area slows cooling and risks pathogen growth.

Question 44Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler is using a slicer to prepare deli meat. How often must the slicer be cleaned and sanitized?

  1. Only when visible residue accumulates
  2. Every 8 hours regardless of use
  3. At least every 4 hours during continuous use Correct answer.
  4. Once at the end of each business day

Explanation

Food-contact surfaces in continuous use with TCS foods must be cleaned and sanitized at least every 4 hours. This limits pathogen growth on equipment that stays in the temperature danger zone. End-of-day cleaning alone is insufficient.

Question 45Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment is receiving a delivery of raw ground beef. Which temperature is acceptable for receiving?

  1. 50°F or lower
  2. 41°F or lower Correct answer.
  3. 45°F or lower
  4. 55°F or lower

Explanation

Raw ground beef is a TCS food and must be received at 41°F or lower. Receiving at higher temperatures indicates temperature abuse and the product should be rejected. Shell eggs and other TCS foods have similar cold receiving requirements.

Question 46Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment uses a reduced-oxygen packaging process for fish. Which control is most important to prevent botulism?

  1. Store the fish at room temperature to allow oxygen exchange
  2. Remove the packaging immediately upon receipt
  3. Freeze the fish for 24 hours before sale
  4. Maintain strict temperature control and limit the shelf life as specified in the approved plan Correct answer.

Explanation

Reduced-oxygen packaged fish can support growth of Clostridium botulinum, so strict temperature control and shelf-life limits from the approved HACCP plan are essential. The product must be kept at or below 38°F for the specified shelf life. Removing the packaging or freezing does not replace the required controls.

Question 47Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler notices that a sanitizing bucket has a cloudy solution and a test strip shows 0 ppm chlorine. What should be done?

  1. Add hot water to activate the chlorine
  2. Discard the solution, prepare a fresh batch, and verify the concentration with a test strip Correct answer.
  3. Use the solution anyway because cloudiness indicates strength
  4. Add more sanitizer until the solution becomes clear

Explanation

A sanitizer solution that tests at 0 ppm is ineffective and must be discarded and remade. The concentration must be verified with the appropriate test strip before use. Cloudiness or guesswork is not a substitute for testing.

Question 48Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment is developing a food defense plan. Which practice best reduces the risk of intentional contamination?

  1. Store cleaning chemicals next to food supplies for convenience
  2. Post the menu in the dining area
  3. Restrict access to food storage areas to authorized employees Correct answer.
  4. Allow delivery drivers to enter the kitchen unsupervised

Explanation

Food defense focuses on preventing intentional contamination by controlling access to food, storage, and preparation areas. Only authorized employees should have access, and visitors should be escorted. Storing chemicals near food or allowing unsupervised access increases risk.

Question 49Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food handler is preparing a large batch of chicken salad. The handler tastes the salad with a spoon and returns the spoon to the bowl. What is the food safety concern?

  1. Saliva can introduce pathogens; the spoon must not be reused and the salad should be evaluated Correct answer.
  2. No concern exists because the handler is healthy
  3. The salad should be reheated to 165°F before service
  4. The concern is only about the salad's flavor

Explanation

Using a utensil that has contacted the mouth and returning it to the food introduces saliva and potential pathogens such as Staphylococcus aureus or norovirus. The utensil must be removed and the food evaluated for safety. Reheating does not reliably eliminate staphylococcal toxins.

Question 50Food safety domains per NRFSP exam blueprint (not enumerated in source)

A food establishment serves a highly susceptible population, such as a hospital. Which practice is required for raw seed sprouts?

  1. Do not serve raw seed sprouts to highly susceptible populations Correct answer.
  2. Serve sprouts if they are labeled organic
  3. Serve sprouts only at breakfast
  4. Serve sprouts only if rinsed with vinegar

Explanation

Raw seed sprouts are a known source of Salmonella and E. coli and must not be served to highly susceptible populations such as hospitalized patients, young children, or older adults. Cooking the sprouts does not necessarily eliminate the risk for this population. Organic labeling does not make them safe.
