HIC Health Inspector Food Safety & Sanitation 3 — Questions and Answers
Question 1: Which of the following best describes the 'danger zone' for temperature control of TCS foods?
- 32°F to 145°F
- 41°F to 135°F (Correct answer)
- 40°F to 140°F
- 45°F to 155°F
Correct answer: 41°F to 135°F
The FDA Food Code defines the temperature danger zone as 41°F to 135°F, the range in which bacterial pathogens can rapidly multiply in TCS foods.
Question 2: A foodservice employee is diagnosed with Shigella. Under the FDA Food Code, the Person in Charge must:
- Allow the employee to work if wearing gloves and a mask
- Restrict the employee to non-food-contact duties only
- Exclude the employee from the establishment entirely (Correct answer)
- Report to the regulatory authority within 7 days
Correct answer: Exclude the employee from the establishment entirely
Shigella is one of the 'Big 6' pathogens requiring exclusion (not just restriction) of the food employee from the establishment.
Question 3: What is the primary purpose of a HACCP plan in a food establishment?
- To document employee training records
- To identify and control biological, chemical, and physical hazards in food production (Correct answer)
- To schedule routine cleaning and sanitation tasks
- To establish a record of customer complaints
Correct answer: To identify and control biological, chemical, and physical hazards in food production
HACCP (Hazard Analysis Critical Control Points) is a systematic preventive approach to identify and control food safety hazards throughout the food production process.
Question 4: A frozen food item arrives at a receiving dock with large ice crystals inside the package and the packaging is stained. This most likely indicates:
- The product was stored too cold during transit
- The product experienced a thaw-refreeze cycle (Correct answer)
- The product was packed with excess moisture
- The product is a higher-quality frozen item
Correct answer: The product experienced a thaw-refreeze cycle
Large ice crystals and stained packaging are signs of a thaw-refreeze cycle, indicating the product's cold chain was compromised.
Question 5: Under FDA Food Code guidelines, what is the maximum time TCS food may be held in the temperature danger zone before it must be discarded?
- 2 hours
- 4 hours (Correct answer)
- 6 hours
- 8 hours
Correct answer: 4 hours
TCS foods must not be in the temperature danger zone (41°F–135°F) for more than 4 cumulative hours before being discarded.
Question 6: Which sanitizer is most affected by organic matter (food debris) reducing its effectiveness?
- Quaternary ammonium compounds
- Iodine-based sanitizers
- Chlorine-based (hypochlorite) sanitizers (Correct answer)
- Hydrogen peroxide sanitizers
Correct answer: Chlorine-based (hypochlorite) sanitizers
Chlorine-based sanitizers are most rapidly inactivated by organic matter, which is why proper cleaning before sanitizing is critical.
Question 7: A health inspector finds a food employee rinsing raw chicken in a three-compartment sink currently set up for dishwashing. What is the primary concern?
- Employee wasting water resources
- Cross-contamination of clean utensils and equipment with raw poultry pathogens (Correct answer)
- The chicken losing moisture during rinsing
- Violation of water temperature regulations
Correct answer: Cross-contamination of clean utensils and equipment with raw poultry pathogens
Using a dishwashing sink to rinse raw poultry introduces Salmonella and Campylobacter into the sanitizing environment, creating a serious cross-contamination hazard.
