1. Which of the following is considered a biological hazard in food?
A. Copper leaching from a brass fitting
B. Norovirus contaminating a salad bar
C. Pieces of broken glass in an ice bin
D. Sanitizer residue left on a prep table
Rationale: Norovirus is a pathogenic microorganism, making it a biological
hazard. Biological hazards include bacteria, viruses, parasites, and fungi that
can cause foodborne illness. Copper leaching and sanitizer residue are chemical
hazards, while broken glass is a physical hazard.
2. What is the minimum internal cooking temperature for poultry, including whole
or ground chicken?
A. 135°F (57°C) for 15 seconds
B. 145°F (63°C) for 15 seconds
C. 155°F (68°C) for 17 seconds
D. 165°F (74°C) for <1 second (instantaneous)
Rationale: Poultry must be cooked to a minimum internal temperature of 165°F
(74°C) instantaneously to ensure the destruction of highly heat-resistant
pathogens like Salmonella, which are commonly associated with birds.
,3. Food handlers must wash their hands for at least how many seconds with soap
and water?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
Rationale: The FDA Food Code specifies that the entire handwashing process
should take at least 20 seconds, with at least 10 to 15 seconds dedicated to
vigorous scrubbing of the hands, fingers, and forearms to physically remove
transient pathogens.
4. What is the maximum allowable internal temperature for cold TCS food during
receiving?
A. 41°F (5°C)
B. 45°F (7°C)
C. 50°F (10°C)
D. 55°F (13°C)
Rationale: To limit the growth of pathogenic bacteria, cold Time/Temperature
Control for Safety (TCS) foods must be received at an internal temperature of
41°F (5°C) or lower, with a few specific exceptions like live shellfish and shell eggs
which can be received at 45°F.
5. A food handler arrives at work with a sore throat and fever. If the establishment
serves a highly susceptible population, the manager must:
A. Allow them to work if they wear a face mask
B. Exclude the food handler from the operation
C. Restrict the food handler to non-food contact duties
D. Send them home only if they work directly with open food
,Rationale: When an operation serves a highly susceptible population (such as a
nursing home, hospital, or preschool), a food handler with a sore throat and
fever must be excluded from the facility entirely due to the high risk of
transmitting Streptococcus pyogenes or other pathogens to vulnerable
individuals.
6. Which of the following is an example of an unapproved chemical sanitizer for
food-contact surfaces?
A. Chlorine
B. Iodine
C. Isopropyl alcohol
D. Quaternary ammonium compounds (Quats)
Rationale: While isopropyl alcohol is a disinfectant used in medical or cleanroom
settings, it is not an approved regulatory sanitizer for food-contact surfaces in
retail food establishments. Chlorine, iodine, and quats are standard EPA-
registered and food-code approved sanitizers.
7. What is the first step in a regular 5-step cleaning and sanitizing process?
A. Scrape or remove food bits from the surface
B. Rinse the surface thoroughly with clean water
C. Apply an approved sanitizing solution
D. Wash the surface with an approved detergent
Rationale: The correct order for manual cleaning and sanitizing is: 1) scrape or
remove food bits, 2) wash with detergent, 3) rinse with clean water, 4) sanitize
with an approved chemical or thermal method, and 5) air-dry. Scraping prevents
gross soils from overwhelming the wash water.
8. What is the primary purpose of a HACCP system?
A. To identify, evaluate, and control food safety hazards
, B. To manage employee payroll and scheduling efficiently
C. To maximize the shelf life and freshness of produce
D. To organize kitchen storage spaces alphabetically
Rationale: Hazard Analysis Critical Control Point (HACCP) is a systematic,
preventive approach to food safety that focuses on identifying biological,
chemical, and physical hazards at specific points in the flow of food so they can
be prevented, eliminated, or reduced to safe levels.
9. Shellstock identification tags must remain attached to the container until the
last shellfish is used, and then kept on file for how many days?
A. 30 days
B. 60 days
C. 90 days
D. 120 days
Rationale: Regulatory authorities require shellstock tags to be kept on file for 90
days from the date the container is emptied. This duration covers the typical
incubation and reporting window for foodborne illnesses like Hepatitis A
associated with contaminated shellfish.
10. Ciguatera poisoning is most commonly associated with consuming
contaminated:
A. Dairy products
B. Marine finfish
C. Poultry
D. Wild mushrooms
Rationale: Ciguatera toxin is a marine toxin that accumulates in the flesh of large
predatory reef fish (such as barracuda, grouper, snapper, and jacks) after they
