Practice Questions (Lessons 1–13) |
QUESTIONS AND ANSWERS

LESSON 1: Introduction to Food Safety
1. What is the primary goal of food protection?

 A) Increasing food production
 B) Preventing foodborne illness
 C) Improving food flavor
 D) Reducing food costs

(Correct Answer: B) Rationale: Food protection aims to prevent illness caused by consuming
contaminated food, protecting public health.



2. Which agency enforces food safety regulations in New York City?

 A) FDA
 B) USDA
 C) NYC Department of Health and Mental Hygiene (DOHMH)
 D) CDC

(Correct Answer: C) Rationale: The NYC DOHMH is responsible for inspecting and
regulating food establishments in New York City.



3. A foodborne illness is defined as:

 A) An allergy caused by eating shellfish
 B) A disease transmitted to humans through contaminated food or water
 C) Indigestion caused by overeating
 D) An illness caused by vitamin deficiency

(Correct Answer: B) Rationale: Foodborne illness results from consuming food or beverages
contaminated with harmful pathogens, toxins, or chemicals.

,4. Which of the following is NOT a common cause of foodborne illness?

 A) Biological hazards
 B) Chemical hazards
 C) Physical hazards
 D) Nutritional hazards

(Correct Answer: D) Rationale: Foodborne illness is caused by biological, chemical, and
physical hazards — not nutritional imbalances.



5. Who is most vulnerable to foodborne illness?

 A) Healthy adults
 B) Athletes
 C) Elderly, young children, pregnant women, and immunocompromised individuals
 D) People who eat organic food

(Correct Answer: C) Rationale: These groups have weaker immune systems or altered
physiology, making them less able to fight pathogens.



6. Which of the following is a biological hazard in food?

 A) A piece of glass
 B) Bacteria
 C) Pesticide residue
 D) A metal fragment

(Correct Answer: B) Rationale: Biological hazards include bacteria, viruses, parasites, and
fungi — living organisms that can cause illness.



7. What does HACCP stand for?

 A) Hazard Analysis and Critical Control Points
 B) Health and Chemical Contamination Prevention
 C) Hazardous Allergy and Contamination Control Process
 D) Health Assessment for Catering and Cooking Practices

(Correct Answer: A) Rationale: HACCP is a systematic preventive approach to food safety
that identifies physical, chemical, and biological hazards.

,8. A chemical hazard in food can result from:

 A) A fly landing on food
 B) Improper use of cleaning agents near food
 C) Undercooked meat
 D) Cross-contamination from raw poultry

(Correct Answer: B) Rationale: Cleaning chemicals improperly stored or used near food can
contaminate it, creating a chemical hazard.



9. Which of the following best describes a physical hazard?

 A) Salmonella in raw chicken
 B) A bone fragment in a fish fillet
 C) Pesticides on vegetables
 D) Mold growing on bread

(Correct Answer: B) Rationale: Physical hazards are foreign objects — like bones, glass, or
metal — that can cause injury if consumed.



10. The "Five Risk Factors" for foodborne illness identified by the CDC include all EXCEPT:

 A) Food from unsafe sources
 B) Inadequate cooking
 C) Improper presentation of food
 D) Poor personal hygiene

(Correct Answer: C) Rationale: The CDC's five risk factors are unsafe sources, inadequate
cooking, improper holding temperatures, contaminated equipment, and poor personal hygiene.



LESSON 2: Microorganisms & Foodborne Illness
11. Which of the following bacteria is commonly associated with undercooked poultry?

 A) Listeria monocytogenes
 B) Clostridium botulinum
 C) Salmonella
 D) Staphylococcus aureus

, (Correct Answer: C) Rationale: Salmonella is commonly found in poultry and eggs and is
destroyed by proper cooking.



12. Staphylococcus aureus causes foodborne illness primarily through:

 A) Spores it forms in soil
 B) Toxins it produces in food
 C) Direct infection of the intestines
 D) Contaminating water supplies

(Correct Answer: B) Rationale: Staph aureus produces heat-stable toxins in food; cooking kills
the bacteria but NOT the toxins already present.



13. What is the temperature danger zone for bacterial growth?

 A) 0°F to 32°F
 B) 41°F to 135°F
 C) 32°F to 70°F
 D) 135°F to 165°F

(Correct Answer: B) Rationale: Bacteria multiply most rapidly between 41°F and 135°F (5°C–
57°C), known as the temperature danger zone.



14. Which virus is the leading cause of foodborne illness in the United States?

 A) Hepatitis A
 B) Rotavirus
 C) Norovirus
 D) HIV

(Correct Answer: C) Rationale: Norovirus is highly contagious and the most common cause of
acute gastroenteritis from contaminated food.



15. Hepatitis A virus is most often transmitted through food by:

 A) Improper refrigeration
 B) An infected food handler with poor hygiene
 C) Using aluminum cookware
