Introduction
This structured SANITARIAN EXAM format for 2026–2027 provides the complete layout for generating high-quality exam-style questions with
correct answers and rationales. It emphasizes foundational environmental health principles, regulatory compliance, public safety protocols, and
evidence-based inspection strategies critical to professional sanitarian practice and successful Registered Environmental Health Specialist/Registered
Sanitarian (REHS/RS) certification.
The official, verified question count for the actual Sanitarian (REHS/RS) Examination is exactly 225 multiple-choice questions (comprising Part 1 with
113 questions and Part 2 with 112 questions). This document mirrors that authentic exam length and structure.
Answer Format
All correct answers appear in BOLD CYAN. Each question includes a concise rationale explaining safety/operational reasoning, regulatory code
adherence, and why alternative options are less appropriate.
1. A food service establishment is using a three-compartment sink for manual warewashing. The proper sequence of the
compartments should be:
A. Sanitize, wash, rinse
B. Wash, rinse, sanitize
C. Rinse, wash, sanitize
D. Wash, sanitize, rinse
Correct Answer: B. Wash, rinse, sanitize
Rationale: The correct order is wash (detergent), rinse (clean water), sanitize (chemical or hot water) to remove soil before applying sanitizer.
2. Which temperature is required for hot holding potentially hazardous foods?
A. 145°F (63°C) or above
B. 120°F (49°C) or above
C. 135°F (57°C) or above
D. 100°F (38°C) or above
Correct Answer: C. 135°F (57°C) or above
Rationale: Hot holding must be maintained at 135°F (57°C) or above to prevent bacterial growth in the temperature danger zone.
3. A cook is preparing a large batch of ground beef. The minimum internal cooking temperature is:
A. 145°F (63°C)
, B. 165°F (74°C)
C. 155°F (68°C)
D. 135°F (57°C)
Correct Answer: C. 155°F (68°C)
Rationale: Ground beef must reach 155°F (68°C) for 17 seconds because grinding distributes pathogens throughout the product.
4. Which organism is most commonly associated with undercooked poultry?
A. Staphylococcus aureus
B. Salmonella
C. Clostridium perfringens
D. Bacillus cereus
Correct Answer: B. Salmonella
Rationale: Salmonella is the primary pathogen of concern in raw or undercooked poultry and must be destroyed by proper cooking.

B. Assign the employee to dishwashing only
C. Send the employee home and exclude from food handling
D. Allow the employee to work if wearing gloves
Correct Answer: C. Send the employee home and exclude from food handling
Rationale: Employees with sore throat and fever must be excluded from food handling to prevent transmission of pathogens like Streptococcus or
Norovirus.
6. What is the maximum temperature for cold holding potentially hazardous foods?
A. 32°F (0°C) or below
B. 41°F (5°C) or below
C. 50°F (10°C) or below
D. 45°F (7°C) or below
Correct Answer: B. 41°F (5°C) or below
Rationale: Cold holding must be at 41°F (5°C) or below to keep food out of the temperature danger zone (41°F–135°F).
7. A food establishment receives a delivery of shell eggs. The eggs must be received at a temperature of:
A. No temperature requirement if they are pasteurized
B. 41°F (5°C) or below
C. 50°F (10°C) or below
D. 45°F (7°C) or below
Correct Answer: D. 45°F (7°C) or below

, A. Rinse with hot water only
B. Apply sanitizer without washing
C. Wash, rinse, and sanitize
D. Wipe with a damp cloth
Correct Answer: C. Wash, rinse, and sanitize
Rationale: Food contact surfaces must be washed, rinsed, and sanitized after contact with raw animal products to prevent cross-contamination.
9. A food handler cuts raw chicken and then slices tomatoes without washing hands or changing gloves. This is an example of:
A. Cross-contamination
B. Poor personal hygiene only
C. Time-temperature abuse
D. Improper storage
Correct Answer: A. Cross-contamination
Rationale: Cross-contamination occurs when pathogens are transferred from one food (raw chicken) to another (tomatoes) via hands, utensils, or
surfaces.

C. 135°F (57°C)
D. 110°F (43°C)
Correct Answer: B. 100°F (38°C)
Rationale: Hot water at the handwashing sink must be at least 100°F (38°C) to effectively remove soil and pathogens.
11. Which food is considered a Time/Temperature Control for Safety (TCS) food?
A. Dry pasta
B. Uncooked rice
C. Cut tomatoes
D. Whole apples
Correct Answer: C. Cut tomatoes
Rationale: Cut tomatoes have a pH above 4.6 and water activity that supports bacterial growth, making them TCS foods.
12. A food establishment is using a chemical sanitizer. The proper concentration for chlorine sanitizer is:
A. 500–1000 ppm
B. 200–400 ppm
C. 50–100 ppm
D. 100–200 ppm
Correct Answer: C. 50–100 ppm
Rationale: Chlorine sanitizers are effective at 50–100 ppm for food contact surfaces when used properly with correct contact time.
, 13. What is the proper procedure for cooling a large pot of soup?

C. Leave it on the stove to cool slowly
D. Place it in the walk-in cooler immediately while still hot
Correct Answer: B. Divide into smaller containers and cool in an ice bath or blast chiller
Rationale: Cooling must be rapid: from 135°F to 70°F within 2 hours and 70°F to 41°F within 4 more hours. Shallow pans or ice baths are required.
14. Which parasite is commonly associated with undercooked pork?
A. Trichinella spiralis
B. Cyclospora
C. Giardia
D. Cryptosporidium
Correct Answer: A. Trichinella spiralis
Rationale: Trichinella spiralis is a roundworm parasite found in undercooked pork and wild game that causes trichinosis.
15. A manager finds that the refrigerator temperature is 48°F. What is the correct action?
A. Adjust the thermostat and monitor
B. Discard all TCS foods that have been in the unit more than 4 hours
C. Move all food to another unit and service the refrigerator
D. Continue operating as normal
Correct Answer: B. Discard all TCS foods that have been in the unit more than 4 hours
Rationale: Food held above 41°F for more than 4 hours is in the danger zone and must be discarded to prevent foodborne illness.
16. Which is an approved method for thawing frozen poultry?
A. In a sink with standing warm water
B. In hot water
C. In a refrigerator at 41°F or below
D. On the counter at room temperature
Correct Answer: C. In a refrigerator at 41°F or below
Rationale: Refrigerator thawing keeps the product at safe temperatures. Other methods risk the outer portions entering the danger zone.
17. A food worker has been diagnosed with hepatitis A. The manager must:
A. Require the worker to wear gloves at all times
B. Allow the worker to continue if asymptomatic
C. Exclude the worker from the establishment
D. Restrict the worker to non-food areas
