DOMAIN 1: FOOD SAFETY FUNDAMENTALS (20 Questions)
Q1: Which of the following is NOT considered a TCS (Time/Temperature Control for Safety)
food?
A. Sliced tomatoes
B. Cooked rice
C. Whole, uncut watermelon
D. Cut leafy greens
Correct Answer: C
Rationale: Whole, uncut watermelon is not a TCS food because intact fruits with protective
rinds do not support rapid bacterial growth. Once cut, watermelon becomes a TCS food. The
FDA Food Code identifies cut melons, cut tomatoes, and cooked rice as TCS foods due to
their pH, water activity, and nutrient content supporting pathogen growth.
Walmart Note: Always date-mark cut produce and store at 41°F or below in produce
preparation areas.
Q2: The "Danger Zone" for bacterial growth in food is defined as:
A. 32°F to 100°F
B. 41°F to 135°F
C. 50°F to 120°F
D. 70°F to 120°F
Correct Answer: B
Rationale: The FDA Food Code defines the Temperature Danger Zone as 41°F to 135°F (5°C to
57°C). Within this range, pathogens can multiply rapidly, doubling in number every 20 minutes
under optimal conditions. Foods held in this zone for more than 4 hours must be discarded.
,Q3: Which pathogen is commonly associated with improperly canned foods and produces a
neurotoxin?
A. Salmonella
B. Clostridium botulinum
C. Listeria monocytogenes
D. Campylobacter jejuni
Correct Answer: B
Rationale: Clostridium botulinum produces botulinum toxin, a potent neurotoxin that causes
botulism. It thrives in low-acid, oxygen-free environments like improperly processed canned
goods. The toxin causes paralysis and can be fatal. Commercially canned goods with bulging
lids should never be used.
Q4: What is the minimum internal cooking temperature for ground beef patties?
A. 135°F for 15 seconds
B. 145°F for 15 seconds
C. 155°F for 15 seconds
D. 165°F for 15 seconds
Correct Answer: C
Rationale: Ground meats must be cooked to 155°F for 15 seconds. The grinding process
distributes surface bacteria throughout the meat, requiring higher temperatures than whole
muscle meats. This is per FDA Food Code §3-401.11.
Q5: Which population group is at highest risk for severe complications from Listeria
monocytogenes infection?
A. Healthy adults aged 18-35
B. Pregnant women and their unborn babies
C. Teenage athletes
D. Middle-aged men
Correct Answer: B
Rationale: Pregnant women are 10 times more likely to get listeriosis, which can cause
miscarriage, stillbirth, or severe illness in newborns. Listeria can grow at refrigeration
temperatures (psychrotrophic), making deli meats and soft cheeses particularly risky for this
population.
Q6: The primary difference between cleaning and sanitizing is:
A. Cleaning removes dirt; sanitizing removes bacteria
B. Cleaning uses soap; sanitizing uses bleach
,C. Cleaning is done daily; sanitizing is done weekly
D. Cleaning removes visible soil; sanitizing reduces pathogens to safe levels
Correct Answer: D
Rationale: Cleaning removes visible food debris and soil using soap and water. Sanitizing
follows cleaning and reduces pathogenic microorganisms to safe levels (99.999% reduction
for food contact surfaces). You cannot sanitize a dirty surface—cleaning must occur first.
Q7: Which of the following is a biological hazard?
A. Broken glass in food
B. Chemical sanitizer residue
C. Salmonella bacteria
D. Metal shavings from equipment
Correct Answer: C
Rationale: Biological hazards include bacteria, viruses, parasites, and fungi. Salmonella is a
biological hazard. Broken glass and metal shavings are physical hazards, while chemical
residues are chemical hazards. The "Big 5" foodborne illnesses tracked by health
departments are biological hazards.
Q8: How long can ready-to-eat TCS food be stored at 41°F or below before requiring
consumption or disposal?
A. 3 days
B. 7 days
C. 10 days
D. 14 days
Correct Answer: B
Rationale: Ready-to-eat TCS foods prepared on-site or opened commercially can be stored
for a maximum of 7 days at 41°F or below. The day of preparation counts as Day 1. This is
the FDA Food Code standard to limit Listeria growth in refrigerated foods.
Walmart Note: Walmart requires strict FIFO (First In, First Out) rotation and clear date
marking on all refrigerated RTE items.
Q9: Which virus is the leading cause of foodborne illness in the United States and is highly
contagious?
A. Hepatitis A
B. Norovirus
C. Rotavirus
D. Influenza
, Correct Answer: B
Rationale: Norovirus causes approximately 50% of all foodborne illness outbreaks in the U.S.
It is extremely contagious (as few as 18 viral particles can cause infection) and spreads
through fecal-oral route, contaminated food, water, or surfaces. Infected workers must be
excluded for 24 hours after symptoms resolve.
Q10: What does HACCP stand for?
A. Hazard Analysis and Critical Control Points
B. Health Assessment for Clean Cooking Procedures
C. Hazardous Agent Control and Contamination Prevention
D. Health Administration for Certified Cooking Professionals
Correct Answer: A
Rationale: HACCP (Hazard Analysis and Critical Control Points) is a systematic preventive
approach to food safety that identifies physical, chemical, and biological hazards in
production processes. While retail establishments like Walmart may not have full HACCP
plans, they apply HACCP principles in their food safety management systems.
Q11: Which bacteria produces a heat-stable toxin that can survive cooking and causes rapid
onset (1-6 hours) of vomiting?
A. Salmonella
B. Staphylococcus aureus
C. E. coli O157:H7
D. Clostridium perfringens
Correct Answer: B
Rationale: Staphylococcus aureus produces enterotoxins that are heat-stable and can
withstand cooking temperatures. Symptoms (vomiting, nausea) appear quickly (1-6 hours)
because the toxin is pre-formed in the food. Common sources include foods handled by
carriers with infected cuts or nasal passages.
Q12: What is the water activity (aw) level below which bacteria will not grow?
A. 0.95
B. 0.85
C. 0.75
D. 0.65
Correct Answer: B
Rationale: Most bacteria require water activity above 0.85 to grow. Foods with aw below 0.85
(like honey, jam, dried pasta) are not TCS foods because they don't support bacterial growth.
However, they may still support yeast and mold growth.
