CMC Kitchen Management and Sanitation 3 — Questions and Answers
Question 1: A food handler returns from a restroom break. What is the correct handwashing procedure time for the actual scrubbing step?
- 5 seconds
- 10 seconds
- 20 seconds (Correct answer)
- 60 seconds
Correct answer: 20 seconds
The FDA Food Code requires at least 20 seconds of vigorous scrubbing with soap to effectively remove pathogens during handwashing.
Question 2: Under OSHA regulations, which document must be available to kitchen employees for every chemical used in the workplace?
- Certificate of Analysis (CoA)
- Safety Data Sheet (SDS) (Correct answer)
- Food Safety Plan
- Material Purchase Order
Correct answer: Safety Data Sheet (SDS)
OSHA's Hazard Communication Standard requires Safety Data Sheets (SDS) to be accessible to employees for all hazardous chemicals, including cleaning agents.
Question 3: What is the maximum time cooked food should remain in the temperature danger zone (41–135°F) during cooling before it must reach 70°F?
- 1 hour
- 2 hours (Correct answer)
- 4 hours
- 6 hours
Correct answer: 2 hours
The FDA Food Code two-stage cooling rule requires food to drop from 135°F to 70°F within 2 hours, then to 41°F within an additional 4 hours.
Question 4: Which kitchen layout principle most effectively reduces cross-contamination risk during food production flow?
- Circular workflow with shared prep stations
- Straight-line workflow separating raw and cooked food areas (Correct answer)
- Open kitchen design with combined prep and service areas
- Back-to-front workflow from service to receiving
Correct answer: Straight-line workflow separating raw and cooked food areas
A straight-line or assembly-line workflow that physically separates raw food preparation from cooked/ready-to-eat areas is the gold standard for preventing cross-contamination.
Question 5: A kitchen employee has been diagnosed with Hepatitis A. Per FDA Food Code, what action must the person in charge (PIC) take?
- Reassign the employee to dishwashing
- Exclude the employee from food handling until medically cleared (Correct answer)
- Require the employee to wear gloves and a mask
- Restrict the employee from handling raw meats only
Correct answer: Exclude the employee from food handling until medically cleared
Hepatitis A is a highly contagious illness; the FDA Food Code requires immediate exclusion of infected food handlers from the establishment until cleared by a health professional.
Question 6: What concentration of quaternary ammonium (quat) sanitizer is typically required for food-contact surface sanitation?
- 10–25 ppm
- 50–100 ppm
- 200–400 ppm (Correct answer)
- 500–1000 ppm
Correct answer: 200–400 ppm
Quaternary ammonium compounds are generally effective at 200–400 ppm for food-contact surface sanitation, though exact ranges vary by product.
Question 7: When must a food handler wash their hands between tasks during food prep?
- Only after handling raw meat
- After each task that could cause contamination, including touching the face, changing gloves, or switching between raw and ready-to-eat foods (Correct answer)
- Once per hour during a shift
- Only before handling unwrapped foods
Correct answer: After each task that could cause contamination, including touching the face, changing gloves, or switching between raw and ready-to-eat foods
Handwashing is required any time a food handler could have contaminated their hands, including after touching the face, changing gloves, or switching food types.
