These 10 free CP-FS questions are organized by exam domain, so you can see how each part of the Certified Professional - Food Safety blueprint is tested. Reveal the answer and explanation under each question.
Domain 1: Foodborne Illness and Epidemiological Principles
Question 1
A food establishment receives three consecutive violations for inadequate cold holding temperatures. Which root cause investigation finding would BEST explain this pattern?
- Multiple employees are inconsistently following temperature monitoring protocols during busy periods
- The walk-in cooler is functioning but overstocked, preventing proper air circulation
- The thermometer calibration has drifted slightly but remains within acceptable manufacturer tolerances
- The delivery schedule conflicts with peak service hours causing temporary temperature fluctuations
Show answer & explanation
Correct answer: B - The walk-in cooler is functioning but overstocked, preventing proper air circulation
Domain 2: HACCP Plans and Other Risk-Based Food Safety Programs
Question 2
During an inspection, an inspector observes a cook handling raw chicken breasts and then immediately picking up a plate of cooked chicken without washing hands. This is:
- A Core violation for general cleanliness
- Acceptable because both items are chicken
- A Priority violation for cross-contamination
- Acceptable if the cook was wearing gloves
Show answer & explanation
Correct answer: C - A Priority violation for cross-contamination
Question 3
A large pot of chili was cooked to the proper temperature and placed in a walk-in cooler for cooling at 2:00 PM. At 4:00 PM, the internal temperature is 75°F. Is this acceptable?
- No - chili must be at 41°F within 2 hours
- No - chili should be at 70°F or below within 2 hours
- Yes - the chili reached 70°F within 2 hours
- Yes - as long as it reaches 41°F by 8:00 PM
Show answer & explanation
Correct answer: B - No - chili should be at 70°F or below within 2 hours
Question 4
A restaurant operates a sous vide cooking program. The FIRST document an inspector should request is:
- A customer complaint log
- A copy of the variance and HACCP plan
- The chef's culinary credentials
- The equipment manufacturer's warranty
Show answer & explanation
Correct answer: B - A copy of the variance and HACCP plan
Question 5
An inspector finds the following during an inspection: a missing ceiling tile, cockroach droppings in a storage closet, and cold-held food at 47°F. How should these be classified?
- Missing ceiling tile = Core; cockroach droppings = Priority Foundation; cold-held food at 47°F = Priority
- All as Core items because the facility is otherwise well-maintained
- Missing ceiling tile = Priority Foundation; cockroach droppings = Core; cold-held food = Priority
- All as Priority items because they were found during the same inspection
Show answer & explanation
Correct answer: A - Missing ceiling tile = Core; cockroach droppings = Priority Foundation; cold-held food at 47°F = Priority
Domain 4: Regulatory Compliance and Standards
Question 6
A caller reports that they and three friends all became ill with vomiting approximately 2-4 hours after eating at a restaurant. Based on the short incubation period and vomiting, which pathogen is MOST likely?
- Listeria monocytogenes (typical incubation 1-70 days)
- Staphylococcus aureus (typical incubation 1-6 hours)
- Salmonella (typical incubation 6-72 hours)
- Hepatitis A (typical incubation 15-50 days)
Show answer & explanation
Correct answer: B - Staphylococcus aureus (typical incubation 1-6 hours)
Question 7
At an event, 40 people ate the shrimp and 20 became ill (50% attack rate). Of the 60 people who did not eat shrimp, 2 became ill (3.3% attack rate). This data suggests:
- More comprehensive laboratory testing and additional epidemiological investigation are required before establishing any definitive causal relationships
- Shrimp cannot be considered the implicated food item since approximately half of those who consumed it remained asymptomatic throughout the event
- The fact that two individuals who avoided shrimp consumption still developed illness definitively rules out shrimp as the contamination source
- Shrimp is strongly implicated because the attack rate is significantly higher among those who ate it compared to those who did not
Show answer & explanation
Correct answer: D - Shrimp is strongly implicated because the attack rate is significantly higher among those who ate it compared to those who did not
Domain 5: Food Safety Program Management
Question 8
A food product contaminated with Listeria monocytogenes would MOST likely be classified as:
- Class II because most people recover from Listeria infections
- Not subject to recall because Listeria occurs naturally in the environment
- Class I because Listeria can cause serious illness and death
- Class III because Listeria contamination is relatively uncommon
Show answer & explanation
Correct answer: C - Class I because Listeria can cause serious illness and death
Domain 6: Employee Food Safety Education and Training
Question 9
An employee notices that the tamper-evident seal on an ingredient delivery is broken. The MOST appropriate FIRST action is to:
- Accept the delivery and note the broken seal in the log
- Open the container to check if the contents appear normal
- Contact the FBI immediately
- Refuse the delivery and notify the supervisor immediately
Show answer & explanation
Correct answer: D - Refuse the delivery and notify the supervisor immediately
Domain 7: Food Allergen Management and Special Processes
Question 10
A food establishment loses power for 6 hours. The walk-in cooler temperature reads 50°F. The MOST appropriate action regarding TCS food stored inside is:
- Move the food outside if the outdoor temperature is below 41°F
- The food is safe because it was cold when the power went out
- Discard TCS food above 41°F for more than 4 hours
- All food must be immediately discarded regardless of temperature
Show answer & explanation
Correct answer: C - Discard TCS food above 41°F for more than 4 hours
