1. What are the five common risk factors for foodborne illness
(FBI) as identified by the CDC?
A. Time-temperature abuse, cross-contamination, poor
personal hygiene, poor cleaning & sanitizing, and improper
cooking.
B. Time-temperature abuse, cross-contamination, poor
cleaning, poor personal hygiene, and purchasing from unsafe
sources.
C. Biological, chemical, physical, and allergenic contaminants.
D. Contaminated equipment, incorrect holding temperature,
poor personal hygiene, improper cooking, and purchasing
from unsafe sources.
Rationale: The CDC specifically identifies these five major risk
factors that contribute to foodborne illness outbreaks.
2. What are the four main factors that contribute to the risk of
foodborne illness?
A. Bacteria, viruses, parasites, and fungi.
B. Time-temperature abuse, cross-contamination, poor
,personal hygiene, and poor cleaning & sanitizing.
C. Purchasing from unsafe sources, improper cooking,
contaminated equipment, and poor hygiene.
D. Biological, chemical, physical, and allergenic contaminants.
Rationale: These four primary operational factors are the main
contributors to foodborne illness risk.
3. Raw chicken is left out at room temperature on a prep
table. What is the most likely risk that could cause a
foodborne illness?
A. Poor personal hygiene.
B. Cross-contamination.
C. Time-temperature abuse.
D. Poor cleaning and sanitizing.
Rationale: Leaving raw chicken at room temperature allows it to
enter the temperature danger zone, where bacteria multiply
rapidly.
4. A waiter cleans a table with a cloth and then puts it back in
his apron. What is the risk that could cause foodborne illness?
A. Time-temperature abuse.
B. Cross-contamination.
C. Poor personal hygiene.
D. Poor cleaning and sanitizing.
Rationale: Using a soiled cloth to clean tables and then reusing
,it can spread pathogens, indicating inadequate cleaning and
sanitizing practices.
5. A measure to preventing foodborne illness is controlling
______ and ______________.
A. pH and moisture.
B. oxygen and acidity.
C. time and temperature.
D. food and equipment.
Rationale: Controlling time and temperature is a critical
preventive measure to keep food out of the danger zone and
inhibit bacterial growth.
6. What is the most important way to prevent a foodborne
illness outbreak caused by bacteria?
A. Good personal hygiene.
B. Purchase from reputable sources.
C. Control time and temperature.
D. Proper cleaning and sanitizing.
Rationale: Bacteria multiply rapidly in the temperature danger
zone; controlling time and temperature is the most effective
preventive measure.
7. What is the most important way to prevent a foodborne
illness outbreak caused by a virus?
A. Control time and temperature.
B. Good personal hygiene.
, C. Purchase from reputable sources.
D. Proper cleaning and sanitizing.
Rationale: Viruses are typically spread through fecal-oral routes
from infected individuals, making good personal hygiene
(especially handwashing) the primary prevention.
8. How can foodborne illness from parasites, fungi, plant
toxins, mushroom toxins, or shellfish toxins be best
prevented?
A. Control time and temperature.
B. Good personal hygiene.
C. Proper cleaning and sanitizing.
D. Purchase from reputable sources.
Rationale: Toxins like these cannot be destroyed by cooking or
freezing, so sourcing from reputable suppliers is the only
reliable prevention.
9. What is a parasite?
A. A single-celled organism that causes infection.
B. A biological contaminant that requires a host to live and
reproduce.
C. A type of toxin found in fish.
D. A virus that causes hepatitis.
Rationale: Parasites are organisms that need a host to survive
and reproduce, making them biological contaminants.
