1. The temperature danger zone for rapid bacterial growth is:
A) 0°F to 32°F (-18°C to 0°C)
B) 32°F to 70°F (0°C to 21°C)
C) 41°F to 135°F (5°C to 57°C)
D) 140°F to 165°F (60°C to 74°C)
Correct Answer: C) 41°F to 135°F (5°C to 57°C)
Rationale: Pathogenic bacteria multiply fastest between 41°F
and 135°F. TCS (Time/Temperature Control for Safety) foods
must be kept below 41°F or above 135°F to prevent foodborne
illness.
2. Which foodborne pathogen is commonly associated with
undercooked ground beef and produces a Shiga toxin?
,Page 2 of 83
A) Salmonella enteritidis
B) Campylobacter jejuni
C) Escherichia coli O157:H7
D) Listeria monocytogenes
Correct Answer: C) Escherichia coli O157:H7
Rationale: E. coli O157:H7 is found in undercooked ground beef,
raw produce, and contaminated water. It causes bloody diarrhea
and hemolytic uremic syndrome (HUS).
3. Scenario: A dietary manager observes a food service
worker taste-testing a soup with the same ladle used to stir
the pot. What is the immediate corrective action?
A) Discard the soup and reheat a new batch
B) Remove the ladle, clean and sanitize it, and reheat the soup to
165°F
C) Warn the employee and continue service
D) Nothing, because the employee tasted only a small amount
,Page 3 of 83
Correct Answer: B) Remove the ladle, clean and sanitize it,
and reheat the soup to 165°F
Rationale: The ladle became contaminated with oral bacteria.
The soup must be reheated to 165°F to destroy pathogens.
Employee must be retrained on no tasting with food contact
surfaces.
4. What is the minimum internal cooking temperature for
poultry (chicken, turkey)?
A) 145°F (63°C) for 15 seconds
B) 155°F (68°C) for 15 seconds
C) 165°F (74°C) for 15 seconds
D) 180°F (82°C) for 1 second
Correct Answer: C) 165°F (74°C) for 15 seconds
Rationale: Poultry and stuffed meats require 165°F to kill
Salmonella and Campylobacter. Ground beef: 155°F;
fish/seafood: 145°F.

5. The first-in, first-out (FIFO) inventory rotation method
ensures:
A) Lower food costs
B) Older products are used before newer products
C) Reduced inventory levels
D) Increased ordering frequency
Correct Answer: B) Older products are used before newer
products
Rationale: FIFO prevents spoilage. Date all products. Place new
items behind older ones. Use oldest stock first.
6. Which sanitizer is most effective in a low-temperature
dishwasher (120°F final rinse)?
A) Quaternary ammonium (quat)
B) Chlorine (bleach)
C) Iodine
D) Peracetic acid
