Question 1Food safety management and Certified Food Protection Manager responsibilities

In a grocery store, who is responsible for ensuring that the written food safety management system is available and that employees follow it during daily operations?

  1. The Certified Food Protection Manager on duty Correct answer.
  2. The cashier scheduled at the front end
  3. The customer service desk supervisor
  4. The supplier delivering refrigerated products

Explanation

The person in charge, typically the Certified Food Protection Manager or designated manager, is accountable for having a documented food safety management system and for making sure employees carry out its procedures. This responsibility cannot be delegated to delivery personnel, cashiers, or other staff who lack food safety oversight duties.

Question 2Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is developing a food safety management system. Which element is the foundation that identifies where significant hazards can occur in each department?

  1. A hazard analysis of the store's processes Correct answer.
  2. A customer satisfaction survey
  3. An employee break schedule
  4. A vendor discount agreement

Explanation

A food safety management system is built on a hazard analysis that identifies biological, chemical, and physical hazards at each step of receiving, storage, preparation, and display. Controls and monitoring are then designed around those identified hazards.

Question 3Food safety management and Certified Food Protection Manager responsibilities

During a self-inspection, the manager finds that the deli slicer is cleaned only once per day even though it is used continuously. What is the most appropriate management response?

  1. Document the finding, correct the cleaning frequency, and retrain staff Correct answer.
  2. Record the finding but take no action because the slicer is in constant use
  3. Wait for the next scheduled health inspection to address it
  4. Assign the issue to the night crew without further follow-up

Explanation

Self-inspection findings must be documented and corrected promptly, and staff must be retrained so the required cleaning frequency is followed. Deferring correction leaves a persistent contamination risk on ready-to-eat food contact surfaces.

Question 4Food safety management and Certified Food Protection Manager responsibilities

Which practice best demonstrates active managerial control over food safety in a grocery store?

  1. Displaying a handwashing sign in the restroom
  2. Posting the health inspection grade at the entrance
  3. Offering food safety pamphlets to customers
  4. Monitoring refrigeration temperatures and recording corrective actions Correct answer.

Explanation

Active managerial control means the manager actively monitors critical processes, records results, and takes corrective action when limits are not met. Temperature monitoring with documented corrections is a direct example of controlling a critical food safety hazard.

Question 5Food safety management and Certified Food Protection Manager responsibilities

A store receives a shipment of frozen shrimp that shows large ice crystals and water stains on the packaging. What should the manager do?

  1. Accept it and label it as fresh
  2. Accept it and sell it at a reduced price
  3. Accept it and refreeze the product immediately
  4. Reject the shipment because it shows signs of temperature abuse Correct answer.

Explanation

Ice crystals and water stains indicate the frozen product may have thawed and refrozen, which signals temperature abuse and possible pathogen growth. The manager should reject the delivery and document the reason.

Question 6Food safety management and Certified Food Protection Manager responsibilities

Which document should a grocery store manager keep to verify that a supplier of raw oysters is approved and that shellfish tags are retained?

  1. Delivery receipts kept for 24 hours
  2. Employee timecards for the delivery crew
  3. Supplier advertising brochures
  4. Shellfish tags kept for at least 90 days from the date of receipt Correct answer.

Explanation

Shellfish tags must be retained for at least 90 days from the date the shellfish is received so the product can be traced to its source if an illness occurs. Keeping tags supports traceability and supplier verification.

Question 7Food safety management and Certified Food Protection Manager responsibilities

A manager is training new employees on reporting responsibilities. Which situation requires an employee to report to the person in charge?

  1. The employee has been diagnosed with a foodborne illness or has symptoms such as vomiting or diarrhea Correct answer.
  2. The employee is requesting a different break time
  3. The employee is scheduled for an extra shift next week
  4. The employee has a minor paper cut on a finger

Explanation

Food employees must report to the person in charge any diagnosis of a foodborne illness and symptoms such as vomiting, diarrhea, jaundice, or sore throat with fever. The manager then decides on exclusion or restriction based on the illness and the employee's duties.

Question 8Food safety management and Certified Food Protection Manager responsibilities

A food employee reports jaundice. What is the manager's most appropriate action?

  1. Exclude the employee from work and require clearance from a health practitioner before return Correct answer.
  2. Allow the employee to work if gloves are worn
  3. Send the employee home for one day and allow return without clearance
  4. Allow the employee to work only at the cash register

Explanation

Jaundice may indicate hepatitis A or another infectious condition, so the person in charge must exclude the employee and require medical clearance before the employee returns to food handling. Gloves and reassignment do not remove the risk of transmitting an infectious disease.

Question 9Food safety management and Certified Food Protection Manager responsibilities

Which handwashing step sequence is correct for a grocery store employee returning from a break?

  1. Apply hand sanitizer only, then return to work
  2. Wipe hands with a cloth towel and continue
  3. Rinse hands with warm water and dry on an apron
  4. Wet hands, apply soap, scrub for at least 10 to 15 seconds, rinse, dry with a single-use towel Correct answer.

Explanation

Proper handwashing requires wetting hands, applying soap, scrubbing for at least 10 to 15 seconds, rinsing thoroughly, and drying with a single-use towel. Hand sanitizer is not a substitute for handwashing when hands are visibly soiled or after using the restroom.

Question 10Food safety management and Certified Food Protection Manager responsibilities

In a grocery store produce department, which situation requires a manager to verify that a corrective action was completed?

  1. A clerk restocked bananas on the shelf
  2. A display case holding cut melon was found at 48°F (9°C) during the morning check Correct answer.
  3. A customer asked for a different brand of apples
  4. A vendor changed the delivery time for bread

Explanation

Cut melon is a time/temperature control for safety food, and holding it at 48°F exceeds the cold-holding limit. The manager must ensure the product is discarded or otherwise handled per procedure and that the case is repaired or adjusted, then document the corrective action.

Question 11Food safety management and Certified Food Protection Manager responsibilities

A manager is deciding whether to exclude or restrict a food employee who has a sore throat with fever. Which factor most affects the decision?

  1. Whether the employee handles exposed food or only works in a non-food area Correct answer.
  2. Whether the employee prefers to take unpaid leave
  3. Whether the store is busy that day
  4. Whether the employee has worked at the store for more than a year

Explanation

The person in charge evaluates the employee's symptoms and duties. An employee with a sore throat and fever who handles exposed food is typically restricted from those duties, while work in non-food areas may be permitted with proper controls.

Question 12Food safety management and Certified Food Protection Manager responsibilities

Which action best prevents cross-contamination in a grocery store that prepares both raw meat and ready-to-eat salads?

  1. Separate cutting boards, utensils, and prep areas for raw animal foods and ready-to-eat foods Correct answer.
  2. Storing raw meat above salads in the same cooler
  3. Using the same cutting board after a quick rinse
  4. Wiping knives on a shared cloth between tasks

Explanation

Cross-contamination is prevented by separating equipment, utensils, and preparation areas used for raw animal foods from those used for ready-to-eat foods. Color-coded or dedicated boards and utensils help enforce the separation.

Question 13Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is reviewing the store's cleaning schedule. Which item must be cleaned and sanitized at a frequency that prevents the buildup of contamination?

  1. The manager's office desk
  2. The customer loyalty card printer
  3. The store's exterior parking lot
  4. Food-contact surfaces such as deli slicers and cutting boards Correct answer.

Explanation

Food-contact surfaces must be cleaned and sanitized at a frequency that prevents contamination of food, typically after each use and between different food types. Non-food surfaces are cleaned on a routine schedule but do not carry the same food safety criticality.

Question 14Food safety management and Certified Food Protection Manager responsibilities

A sanitizer solution in a three-compartment sink is being used for food-contact surfaces. What should the manager verify?

  1. The solution is hot enough to steam
  2. The concentration is within the manufacturer's specified range and is tested with the appropriate test kit Correct answer.
  3. The solution has been used for at least one full shift
  4. The solution color matches the label

Explanation

Sanitizer effectiveness depends on using the correct concentration for the specified contact time, which must be verified with the appropriate test kit. Too weak a solution fails to sanitize, and too strong a solution may be unsafe or leave residue.

Question 15Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager discovers that a cooler has been holding raw chicken at 50°F (10°C) for an unknown period. What is the safest management decision?

  1. Rinse the chicken and return it to the cooler
  2. Sell the chicken immediately at a discount
  3. Discard the chicken because time and temperature history cannot be verified Correct answer.
  4. Move the chicken to a freezer and sell it later

Explanation

When a time/temperature control for safety food has been held above the required temperature for an unknown period, its safety cannot be verified, so it must be discarded. Rinsing, refreezing, or discounting does not eliminate pathogens that may have multiplied.

Question 16Food safety management and Certified Food Protection Manager responsibilities

Which temperature is the correct cold-holding limit for time/temperature control for safety foods in a grocery display case?

  1. 41°F (5°C) or below Correct answer.
  2. 70°F (21°C) or below
  3. 50°F (10°C) or below
  4. 60°F (16°C) or below

Explanation

Time/temperature control for safety foods must be held at 41°F (5°C) or below to slow pathogen growth. Higher holding temperatures allow rapid multiplication of bacteria such as Listeria and Salmonella.

Question 17Food safety management and Certified Food Protection Manager responsibilities

A manager is verifying that a new employee understands the store's food safety management system. Which approach best confirms understanding?

  1. Posting the policy on the break room wall
  2. Observing the employee perform tasks and reviewing documented monitoring records Correct answer.
  3. Asking the employee to sign a handbook acknowledgment only
  4. Giving the employee a copy of the policy to read at home

Explanation

Training is verified through observation of actual performance and review of monitoring records, which show whether procedures are being followed. A signature, handout, or posted policy documents awareness but does not confirm correct practice.

Question 18Food safety management and Certified Food Protection Manager responsibilities

Which situation in a grocery store most clearly requires a written corrective action record?

  1. A customer requests a different flavor of ice cream
  2. An employee takes a scheduled lunch break
  3. A refrigeration unit is found above the cold-holding limit during a monitoring check Correct answer.
  4. A vendor delivers bread earlier than expected

Explanation

Monitoring deviations from critical limits, such as a refrigeration unit above the cold-holding limit, must be followed by corrective action and documentation. The record shows what happened, what was done with the affected product, and how the problem was fixed.

Question 19Food safety management and Certified Food Protection Manager responsibilities

A store manager is evaluating a pest control program. Which practice best supports an effective integrated pest management approach?

  1. Sealing entry points, eliminating food and water sources, and monitoring with scheduled inspections Correct answer.
  2. Setting out rodenticide in open food storage areas
  3. Ignoring occasional sightings if no product damage is visible
  4. Spraying pesticides on food-contact surfaces during operating hours

Explanation

Integrated pest management emphasizes prevention through exclusion, sanitation, and monitoring rather than relying on chemicals alone. Sealing entry points, removing food and water, and inspecting regularly reduce pest pressure and detect problems early.

Question 20Food safety management and Certified Food Protection Manager responsibilities

A grocery store receives a delivery of canned goods. Which condition should cause the manager to reject the product?

  1. Cans stacked in sturdy cases
  2. Cans that are dry and at room temperature
  3. Cans with dents along the seams or swollen ends Correct answer.
  4. Cans with intact labels and no damage

Explanation

Dented seams and swollen ends can indicate a breach in the can's integrity or microbial spoilage, so those cans must be rejected. Undamaged cans held at room temperature are acceptable for storage.

Question 21Food safety management and Certified Food Protection Manager responsibilities

Which record is most useful for demonstrating that a grocery store's food safety management system is working over time?

  1. Customer complaint forms about product selection
  2. Employee vacation requests
  3. Completed temperature logs with corrective action notes Correct answer.
  4. Supplier marketing catalogs

Explanation

Completed monitoring logs with corrective action notes provide a documented history that critical limits were monitored and deviations were corrected. This record is central evidence that the food safety management system functions day to day.

Question 22Food safety management and Certified Food Protection Manager responsibilities

A grocery store employee is assigned to prepare raw meat and then ready-to-eat sandwiches. What is the minimum requirement before moving to the sandwich task?

  1. Wait until the end of the shift to change gloves
  2. Wipe hands on a clean apron and continue
  3. Change gloves and wash hands, and use clean sanitized utensils and surfaces Correct answer.
  4. Rinse gloves with water and continue

Explanation

When moving from raw animal foods to ready-to-eat foods, employees must wash hands and change gloves, and use cleaned and sanitized utensils and surfaces. This prevents pathogens from raw meat from transferring to ready-to-eat food.

Question 23Food safety management and Certified Food Protection Manager responsibilities

A manager is developing a plan for a power outage that could affect refrigerated displays. Which element is most important for protecting food safety?

  1. A schedule for restocking shelves after power returns
  2. A plan to keep the doors closed and hope power returns quickly
  3. A list of customer refund policies
  4. A written procedure for monitoring product temperatures and deciding what to discard Correct answer.

Explanation

An emergency plan should specify how product temperatures will be monitored during an outage and the criteria for keeping or discarding food. Documented decision rules protect customers when refrigeration is interrupted.

Question 24Food safety management and Certified Food Protection Manager responsibilities

Which responsibility belongs to the person in charge regarding employee training in a grocery store?

  1. Ensuring employees are trained on their assigned food safety duties before they perform them Correct answer.
  2. Delegating all training to the newest employee
  3. Allowing employees to learn by trial and error during busy periods
  4. Providing training only after a health inspection citation

Explanation

The person in charge must ensure employees receive training on the food safety procedures relevant to their duties before they perform those tasks. Training before assignment prevents unsafe practices from becoming habits.

Question 25Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is evaluating whether a supplier's food safety documentation is adequate. Which combination best supports approval of the supplier?

  1. A verbal assurance from the sales representative
  2. A low price list and a fast delivery schedule
  3. A large product catalog and a long-standing sales relationship
  4. A current food safety inspection report and a documented traceability or recall process Correct answer.

Explanation

Supplier approval should be based on evidence of food safety control, such as current inspection results and a documented traceability or recall process. Price, catalog size, and verbal assurances do not demonstrate that the supplier controls hazards.

Question 26Food safety management and Certified Food Protection Manager responsibilities

In a grocery store, which responsibility belongs to the person in charge (PIC) regarding food safety management?

  1. Ensuring that food employees are trained in food safety principles and that they follow proper procedures Correct answer.
  2. Performing microbiological testing of food samples in the store laboratory
  3. Approving all supplier contracts and verifying their food safety certificates
  4. Conducting daily inspections of all food preparation areas and documenting them

Explanation

The person in charge is responsible for ensuring that employees are trained in food safety and that they adhere to proper procedures. This includes monitoring employee health, hygiene, and food handling practices. While the PIC may delegate tasks, the ultimate responsibility for training and compliance rests with them.

Question 27Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is reviewing the store's food safety management system. Which document is essential to demonstrate that the system is based on HACCP principles?

  1. A schedule of employee vacation days
  2. A copy of the store's marketing plan
  3. A written HACCP plan that identifies critical control points and critical limits Correct answer.
  4. A list of employee birthdays and contact information

Explanation

A HACCP-based food safety management system requires a written plan that identifies hazards, critical control points (CCPs), critical limits, monitoring procedures, corrective actions, and verification steps. This document is essential to show that the system is properly designed and implemented. The other options are unrelated to food safety management.

Question 28Food safety management and Certified Food Protection Manager responsibilities

A grocery store employee is diagnosed with an infection caused by Salmonella Typhi. What action should the manager take?

  1. Require the employee to wash hands frequently and continue working
  2. Restrict the employee to non-food handling duties
  3. Allow the employee to work if they wear gloves
  4. Exclude the employee from the food establishment and notify the regulatory authority Correct answer.

Explanation

An employee diagnosed with Salmonella Typhi must be excluded from the food establishment because the pathogen can be shed and transmitted to food, causing severe illness. The manager must also notify the regulatory authority as required by food code. Restriction or other measures are not sufficient for this high-risk pathogen.

Question 29Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is verifying that a new employee understands the store's food safety management system. Which approach best confirms understanding?

  1. Observing the employee for one day without providing feedback
  2. Asking the employee to explain the steps they would take if they observed a cooler running warm Correct answer.
  3. Having the employee sign a form acknowledging they received the training
  4. Giving the employee a written test with multiple-choice questions

Explanation

Asking the employee to explain the steps they would take in a specific scenario tests their practical understanding and ability to apply the system. This is more effective than simply signing a form, taking a written test, or passive observation, as it requires the employee to demonstrate knowledge and problem-solving.

Question 30Food safety management and Certified Food Protection Manager responsibilities

A grocery store receives a shipment of frozen shrimp. Which condition should cause the manager to reject the product?

  1. The shrimp are partially thawed with ice crystals and fluid in the package Correct answer.
  2. The shrimp are packaged in vacuum-sealed bags
  3. The shrimp are labeled with a lot code and expiration date
  4. The shrimp are frozen solid and the package is intact

Explanation

Partially thawed shrimp with ice crystals and fluid indicate temperature abuse and possible refreezing, which can compromise food safety and quality. Such products should be rejected. Frozen solid shrimp with intact packaging, vacuum-sealed bags, and proper labeling are acceptable.

Question 31Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is developing a plan for a power outage that could affect refrigerated displays. Which element is most important to include in the plan?

  1. A schedule for restocking shelves after the power returns
  2. A procedure for monitoring product temperatures and deciding when to discard food Correct answer.
  3. A list of employees who are trained in first aid
  4. A plan for notifying customers about the outage

Explanation

During a power outage, the critical food safety concern is maintaining proper temperatures. The plan must include monitoring product temperatures and determining when food must be discarded to prevent foodborne illness. The other elements are secondary or unrelated to food safety.

Question 32Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is reviewing the store's cleaning schedule. Which item must be cleaned and sanitized at a frequency that prevents contamination of food?

  1. Walls in the storage area
  2. Ceiling vents in the produce department
  3. Floors in the employee break room
  4. Food-contact surfaces such as cutting boards and slicers Correct answer.

Explanation

Food-contact surfaces must be cleaned and sanitized at a frequency that prevents contamination of food, typically after each use or at least every four hours if in continuous use. Floors, walls, and ceilings are not food-contact surfaces and have different cleaning frequencies.

Question 33Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager discovers that a cooler has been holding raw chicken at 50°F (10°C) for an unknown period. What is the most appropriate action?

  1. Cook the chicken immediately and sell it in the deli
  2. Quickly chill the chicken to 41°F (5°C) and sell it
  3. Move the chicken to another cooler and monitor it
  4. Discard the chicken and determine the cause of the temperature abuse Correct answer.

Explanation

Raw chicken held above 41°F (5°C) for an unknown period may have allowed pathogens to multiply to unsafe levels. The chicken must be discarded. The manager should also investigate the cause to prevent recurrence. Rapid chilling or cooking does not make the food safe if it has been temperature abused.

Question 34Food safety management and Certified Food Protection Manager responsibilities

A store manager is evaluating a pest control program. Which practice best supports an effective integrated pest management (IPM) approach?

  1. Sealing cracks and gaps in walls and doors to prevent pest entry Correct answer.
  2. Using chemical sprays as the primary method of pest control
  3. Ignoring pest sightings unless they are reported by customers
  4. Leaving food waste in open containers for easy disposal

Explanation

Integrated pest management emphasizes prevention through exclusion, sanitation, and habitat modification. Sealing entry points is a key preventive measure. Chemical sprays should be used judiciously, not as the primary method. Food waste should be in closed containers, and pest sightings should be actively monitored.

Question 35Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is evaluating whether a supplier's food safety documentation is adequate. Which combination best indicates a reliable supplier?

  1. A signed contract and a list of references
  2. A recent promotional brochure and a website
  3. A low price and a large product variety
  4. A current food safety certification and a history of passing inspections Correct answer.

Explanation

A reliable supplier should have current food safety certification (such as GFSI-benchmarked certification) and a history of passing regulatory inspections. These indicate a commitment to food safety. Price, variety, contracts, references, brochures, and websites do not directly demonstrate food safety competency.

Question 36Food safety management and Certified Food Protection Manager responsibilities

A grocery store manager is reviewing the store's food safety management system. Which record is most useful for demonstrating that the system is working over time?

  1. Employee training certificates
  2. Customer feedback forms
  3. Supplier invoices
  4. Temperature logs for coolers and freezers Correct answer.

Explanation

Temperature logs provide ongoing evidence that critical limits for cold holding are being met, demonstrating the effectiveness of the food safety management system. Training certificates show that training occurred but not ongoing compliance. Invoices and feedback forms are not direct measures of food safety performance.

Question 37Food safety management and Certified Food Protection Manager responsibilities

A grocery store's person in charge (PIC) is assigning daily duties. Which task may the PIC delegate to a trained deli associate while remaining accountable for the outcome?

  1. Approving a supplier's food safety audit documents
  2. Determining whether an employee must be excluded for illness
  3. Recording slicer sanitizer concentration on the daily log Correct answer.
  4. Deciding whether to close the store after a sewage backup

Explanation

The PIC is accountable for food safety management but may assign routine monitoring tasks, such as checking and recording sanitizer concentration, to trained staff. Decisions that require managerial judgment, such as exclusion of ill employees, supplier approval, or closure after contamination events, stay with the PIC.

Question 38Food safety management and Certified Food Protection Manager responsibilities

Under a food safety management system, which action best demonstrates that a grocery store's PIC is actively verifying that control measures are working rather than merely documenting them?

  1. Filing completed temperature logs at the end of each week
  2. Posting handwashing signs at every department sink
  3. Scheduling monthly staff meetings to discuss customer complaints
  4. Reviewing temperature logs for trends and out-of-range readings and adjusting procedures Correct answer.

Explanation

Verification means confirming that monitoring and control measures are effective, which requires the PIC to analyze records for patterns and take action when readings drift or fail. Filing logs, posting signs, and holding meetings support the system but do not by themselves confirm that controls are working.

Question 39Food safety management and Certified Food Protection Manager responsibilities

A grocery store's food safety management plan identifies raw poultry handling as a significant hazard. Which element should the plan specify to make this hazard controllable?

  1. A critical limit and the monitoring frequency for the control measure Correct answer.
  2. The name of the supplier that delivers the poultry
  3. The brand of cutting board used in the meat department
  4. The number of associates scheduled per shift

Explanation

A hazard is controlled when the plan defines the control measure, its critical limit, and how often and by whom it is monitored. Brand names, supplier names, and staffing levels do not establish whether the control is being achieved.

Question 40Food safety management and Certified Food Protection Manager responsibilities

A grocery store PIC learns that a foodborne illness complaint may be linked to the store's prepared salads. Which first action best reflects the PIC's responsibility in the food safety management system?

  1. Discard all prepared salads and wait for the customer to provide medical records
  2. Continue normal sales while reviewing the recipe for errors
  3. Contact the regulatory authority, segregate suspect product, and begin a complaint investigation Correct answer.
  4. Ask the customer to sign a waiver before the store takes any action

Explanation

When a complaint suggests a possible foodborne illness linked to store food, the PIC should notify the regulatory authority, hold or segregate suspect product, and investigate while preserving records. Waiting for medical proof, seeking a waiver, or continuing sales delays a response and may allow further illness.

Question 41Foodborne illness and risk factors

A grocery store deli sells sliced roast beef held in a hot case at 118°F (48°C). Which biological risk factor does this represent?

  1. Time-temperature abuse Correct answer.
  2. Purchasing from an unapproved supplier
  3. Cross-contamination
  4. Poor personal hygiene

Explanation

Hot TCS food must be held at 135°F (57°C) or higher, so 118°F keeps the meat in the temperature danger zone where bacteria multiply quickly. Holding food at the wrong temperature is the definition of time-temperature abuse.

Question 42Foodborne illness and risk factors

Which of these grocery items is a TCS food that requires time or temperature control for safety?

  1. Canned green beans
  2. Fresh cut cantaloupe Correct answer.
  3. Dry pasta in sealed boxes
  4. Whole uncut bananas

Explanation

Cut melons are TCS foods because cutting exposes the moist, nutrient-rich interior to microbial growth, so they must be held at 41°F (5°C) or lower. Whole bananas, canned goods, and dry pasta are not TCS foods.

Question 43Foodborne illness and risk factors

An employee at a store seafood counter handles raw shrimp, then uses the same gloved hands to bag cooked crab legs. What risk factor does this create?

  1. Cross-contamination Correct answer.
  2. Chemical contamination
  3. Time-temperature abuse
  4. Poor personal hygiene

Explanation

Pathogens from raw shrimp are transferred to ready-to-eat crab legs through the shared gloves, which is cross-contamination. Gloves must be changed and hands washed whenever switching between raw and ready-to-eat foods.

Question 44Foodborne illness and risk factors

What is the temperature range of the danger zone in which TCS foods should not be held?

  1. 32°F to 41°F (0°C to 5°C)
  2. 41°F to 135°F (5°C to 57°C) Correct answer.
  3. 135°F to 165°F (57°C to 74°C)
  4. 0°F to 32°F (-18°C to 0°C)

Explanation

The danger zone is 41°F to 135°F (5°C to 57°C), the range in which bacteria multiply most rapidly. Cold TCS foods must be held at 41°F or below, and hot TCS foods at 135°F or above.

Question 45Foodborne illness and risk factors

Which of these is a biological contaminant of concern in grocery deli salads?

  1. Broken glass
  2. Sanitizer residue
  3. Listeria monocytogenes Correct answer.
  4. Metal shavings

Explanation

Listeria monocytogenes is a bacterium that can grow in refrigerated ready-to-eat foods such as deli salads and is a biological contaminant. Sanitizer, glass, and metal are physical or chemical contaminants.

Question 46Foodborne illness and risk factors

A customer reports that a store employee came to work with vomiting and diarrhea. Which foodborne illness risk factor does working while ill represent?

  1. Time-temperature abuse
  2. Cross-contamination
  3. Poor personal hygiene Correct answer.
  4. Unapproved supplier

Explanation

Working while ill with vomiting or diarrhea is a personal hygiene risk factor because pathogens such as norovirus can be shed and spread to food. Employees with these symptoms must be excluded from food handling.

Question 47Foodborne illness and risk factors

Which practice best prevents contamination of ready-to-eat foods in a grocery store?

  1. Storing raw poultry above deli salads in the cooler
  2. Reusing cardboard boxes for produce storage
  3. Thawing frozen fish on the counter overnight
  4. Washing hands after handling raw meat and before touching ready-to-eat food Correct answer.

Explanation

Handwashing after contact with raw meat removes pathogens before they can reach ready-to-eat foods, preventing cross-contamination. The other practices all increase the risk of contamination.

Question 48Foodborne illness and risk factors

Which of these is a physical contaminant that could enter food in a grocery store?

  1. Salmonella
  2. Norovirus
  3. Cleaning solution
  4. Staples from a shipping carton Correct answer.

Explanation

Staples from cartons are hard objects that can injure a customer and are classified as physical contaminants. Norovirus and Salmonella are biological, and cleaning solution is chemical.

Question 49Foodborne illness and risk factors

A store displays raw chicken on a shelf directly above open containers of fresh berries in the same cooler. What is the primary food safety concern?

  1. The chicken will cool too quickly
  2. The cooler will use too much energy
  3. The berries will dry out
  4. Raw juices may drip onto the berries and cause cross-contamination Correct answer.

Explanation

Raw poultry juices can drip downward onto ready-to-eat berries, transferring pathogens such as Salmonella and Campylobacter. Raw animal foods must be stored below ready-to-eat foods.

Question 50Foodborne illness and risk factors

An employee is diagnosed with Salmonella infection. According to food safety rules, what should the manager do?

  1. Require the employee to wear gloves while working
  2. Move the employee to the produce stocking area
  3. Exclude the employee from food handling and notify the regulatory authority as required Correct answer.
  4. Allow the employee to work only at the cash register

Explanation

Employees diagnosed with Salmonella Typhi or other reportable infections must be excluded from food handling, and the person in charge must report to the regulatory authority as required by local rules. Gloves or reassignment do not remove the risk.
