CMC Kitchen Management & Sanitation 2 — Questions and Answers
Question 1: What is the minimum internal temperature for cooking whole poultry according to USDA food safety guidelines?
- 155°F (68°C)
- 160°F (71°C)
- 165°F (74°C) (Correct answer)
- 170°F (77°C)
Correct answer: 165°F (74°C)
Whole poultry must reach 165°F (74°C) to ensure destruction of Salmonella and other pathogens.
Question 2: Which cleaning method is most effective for removing biofilm from food-contact surfaces in a commercial kitchen?
- Rinsing with hot water only
- Mechanical scrubbing with detergent followed by sanitizing (Correct answer)
- Applying bleach solution without prior cleaning
- Wiping with dry cloth
Correct answer: Mechanical scrubbing with detergent followed by sanitizing
Biofilm requires mechanical action plus detergent to break down the matrix before sanitizing can be effective.
Question 3: A FIFO inventory system in kitchen management stands for:
- First In, Final Out
- First In, First Out (Correct answer)
- Fresh Items, Fresh Output
- Fixed Inventory, Fixed Output
Correct answer: First In, First Out
FIFO (First In, First Out) ensures older stock is used before newer stock to minimize spoilage and waste.
Question 4: What is the correct concentration range for a chlorine-based sanitizer solution used on food-contact surfaces?
- 10–25 ppm
- 50–100 ppm (Correct answer)
- 200–250 ppm
- 300–400 ppm
Correct answer: 50–100 ppm
Chlorine sanitizer for food-contact surfaces should be 50–100 ppm, effective against pathogens without leaving harmful residue.
Question 5: Which pest is most commonly associated with contaminating dry goods such as flour and grains in a commercial kitchen?
- German cockroach
- Norway rat
- Indian meal moth (Correct answer)
- Fruit fly
Correct answer: Indian meal moth
Indian meal moths infest dry pantry goods like flour, cereals, and spices, making them a major dry-storage pest.
Question 6: What does the term 'cross-contamination' specifically refer to in a food safety context?
- Cooking food at incorrect temperatures
- Transfer of harmful microorganisms from one food or surface to another (Correct answer)
- Improper storage of chemicals near food
- Using expired sanitizing solutions
Correct answer: Transfer of harmful microorganisms from one food or surface to another
Cross-contamination is the transfer of pathogens from a contaminated source (raw meat, unclean surfaces) to ready-to-eat food.
Question 7: In a commercial kitchen, which type of thermometer is considered most accurate for verifying the temperature of thin foods like hamburger patties?
- Bimetallic stemmed thermometer
- Infrared thermometer
- Thermocouple thermometer (Correct answer)
- Glass mercury thermometer
Correct answer: Thermocouple thermometer
Thermocouple thermometers provide rapid, accurate readings and have a very small sensing area, ideal for thin foods.
