SNA Food Safety & Sanitation 3 — Questions and Answers
Question 1: In the HACCP system, what is a Critical Control Point (CCP)?
- Any step where food is inspected for quality
- A step where a control measure can prevent or eliminate a food safety hazard (Correct answer)
- The final step before food is served to students
- A documentation requirement for food recalls
Correct answer: A step where a control measure can prevent or eliminate a food safety hazard
A CCP is a specific point in the food process where control measures can be applied to prevent, eliminate, or reduce food safety hazards to acceptable levels.
Question 2: Which type of thermometer is most appropriate for checking the internal temperature of a thin hamburger patty?
- Bimetallic stemmed thermometer
- Thermocouple thermometer (Correct answer)
- Glass mercury thermometer
- Infrared surface thermometer
Correct answer: Thermocouple thermometer
Thermocouple thermometers have a thin probe tip that provides accurate readings for thin foods quickly, making them ideal for hamburger patties.
Question 3: A school food service worker accidentally uses a food-grade sanitizer at 10 times the recommended concentration. What is the primary concern?
- The sanitizer will not be effective at that concentration
- Chemical contamination of food contact surfaces poses a health risk (Correct answer)
- The sanitizer will damage stainless steel equipment
- There is no concern since more sanitizer is always safer
Correct answer: Chemical contamination of food contact surfaces poses a health risk
Excessive sanitizer concentration leaves harmful chemical residues on food contact surfaces, which can contaminate food and harm students.
Question 4: Milk cartons should be stored in the refrigerator at what maximum temperature?
- 45°F (7°C)
- 41°F (5°C) (Correct answer)
- 50°F (10°C)
- 38°F (3°C)
Correct answer: 41°F (5°C)
TCS (Temperature Control for Safety) foods including milk must be kept at 41°F (5°C) or below to inhibit bacterial growth.
Question 5: Which practice best prevents cross-contamination when preparing raw chicken and fresh salad greens?
- Wash hands between tasks using the same cutting board
- Use separate color-coded cutting boards for each food type (Correct answer)
- Prepare raw chicken last after all produce is handled
- Rinse the cutting board with hot water between uses
Correct answer: Use separate color-coded cutting boards for each food type
Color-coded cutting boards (e.g., yellow for poultry, green for produce) physically prevent raw proteins from contaminating ready-to-eat foods.
Question 6: According to food safety guidelines, cooked foods must be cooled from 135°F to 70°F within what time frame?
- 4 hours
- 2 hours (Correct answer)
- 6 hours
- 1 hour
Correct answer: 2 hours
The first cooling stage requires reducing temperature from 135°F to 70°F within 2 hours to minimize pathogen growth in the danger zone.
Question 7: What is the purpose of a variance from the regulatory authority in a HACCP plan?
- To allow food preparation without temperature controls
- To permit a food process that deviates from standard food safety requirements (Correct answer)
- To reduce the number of required temperature logs
- To skip the hazard analysis step for low-risk foods
Correct answer: To permit a food process that deviates from standard food safety requirements
A variance allows a food establishment to use a non-standard process (such as curing or smoking) that requires regulatory review and approval.
