Temperature Control & TCS Foods
What is the temperature range of the 'danger zone' in which bacteria multiply most rapidly?
- A. 32°F to 100°F (0°C to 38°C)
- B. 41°F to 135°F (5°C to 57°C)
- C. 50°F to 165°F (10°C to 74°C)
- D. 40°F to 140°F (4°C to 60°C)
Answer: B. The FDA Food Code defines the temperature danger zone as 41°F to 135°F (5°C to 57°C). Within this range, bacteria can double in number every 20 minutes under ideal conditions. TCS (Time/Temperature Control for Safety) foods must not remain in this zone for more than 4 cumulative hours.
HACCP & Food Safety Management
How many principles make up the HACCP (Hazard Analysis Critical Control Point) system?
- A. 5
- B. 6
- C. 7
- D. 9
Answer: C. The HACCP system consists of 7 principles: (1) Conduct a hazard analysis, (2) Identify critical control points (CCPs), (3) Establish critical limits, (4) Establish monitoring procedures, (5) Identify corrective actions, (6) Verify the system works, and (7) Establish record-keeping procedures. These principles form the foundation of a science-based preventive food safety system.
Personal Hygiene & Employee Health
According to the FDA Food Code, for how long must food handlers scrub their hands and arms with soap during the handwashing process?
- A. 10 to 15 seconds
- B. 20 seconds
- C. 30 seconds
- D. 60 seconds
Answer: B. The FDA Food Code's handwashing procedure requires food handlers to vigorously scrub their hands and arms with soap for at least 10 to 15 seconds (ServSafe specifically cites 10–15 seconds of scrubbing), with the total handwashing process — including wetting, soaping, scrubbing, rinsing, and drying — taking approximately 20 seconds. The 20-second benchmark is the most commonly cited standard in ServSafe materials.
