CMC Kitchen Management & Sanitation 1 — Questions and Answers
Question 1: What is the recommended minimum internal temperature for cooked poultry?
- 145°F (63°C)
- 150°F (66°C)
- 165°F (74°C) (Correct answer)
- 160°F (71°C)
Correct answer: 165°F (74°C)
The recommended minimum internal temperature for cooked poultry, such as chicken or turkey, is 165°F (74°C). Cooking poultry to this temperature ensures that harmful bacteria, like Salmonella, are destroyed throughout the meat. This critical step is essential for food safety and preventing foodborne illnesses.
Question 2: Why is it important to clean and sanitize food contact surfaces?
- To remove stains
- To make equipment shiny
- To prevent pest infestation
- To reduce pathogens to safe levels (Correct answer)
Correct answer: To reduce pathogens to safe levels
Cleaning removes visible dirt and food particles, while sanitizing reduces the number of harmful microorganisms (pathogens) on food contact surfaces to safe levels. This two-step process is critical in preventing cross-contamination and the spread of foodborne illnesses. Maintaining clean and sanitized surfaces ensures a safe food preparation environment.
Question 3: What is cross-contamination?
- Cleaning surfaces with hot water
- Using only fresh produce
- Storing raw and cooked foods separately
- Transfer of bacteria between foods or surfaces (Correct answer)
Correct answer: Transfer of bacteria between foods or surfaces
Cross-contamination occurs when harmful bacteria or other microorganisms are transferred from one food item (especially raw foods like meat) to another food, or from contaminated surfaces, equipment, or hands to food. This transfer can lead to foodborne illness if the contaminated food is then consumed without proper cooking. Preventing cross-contamination is a fundamental principle of food safety.
Question 4: Which is a critical step in handwashing?
- Drying hands with a cloth towel
- Using scented soap
- Scrubbing hands for 5 seconds
- Scrubbing for at least 20 seconds (Correct answer)
Correct answer: Scrubbing for at least 20 seconds
Proper handwashing is a critical step in food safety, and scrubbing hands with soap for at least 20 seconds is essential. This duration allows enough time for the soap and friction to effectively dislodge and remove transient microorganisms from the skin. Thorough scrubbing significantly reduces the risk of spreading pathogens from hands to food or surfaces.
Question 5: What type of thermometer is best for measuring the temperature of thin foods?
- Bimetallic stemmed thermometer
- Thermocouple (Correct answer)
- Infrared thermometer
- Time-temperature indicator
Correct answer: Thermocouple
Thermocouples are highly accurate digital thermometers that measure temperature through a thin metal probe, making them ideal for measuring the internal temperature of thin foods like hamburger patties, chicken breasts, or fish fillets. Their fast response time and precise readings ensure food safety without overcooking. Infrared thermometers measure surface temperature, and bimetallic stemmed thermometers are generally thicker and slower.
Question 6: Which food should be stored on the top shelf of a refrigerator?
- Raw poultry
- Raw seafood
- Raw ground meat
- Ready-to-eat foods (Correct answer)
Correct answer: Ready-to-eat foods
Ready-to-eat foods should be stored on the top shelf to prevent cross-contamination from raw foods.
Question 7: What is the danger zone temperature range for food safety?
- 32°F to 120°F
- 41°F to 135°F (Correct answer)
- 45°F to 140°F
- 40°F to 130°F
Correct answer: 41°F to 135°F
The danger zone (41°F to 135°F) is the range in which bacteria grow most rapidly.
Question 8: Why should food handlers avoid wearing jewelry in the kitchen?
- It may get damaged
- It looks unprofessional
- It might harbor bacteria (Correct answer)
- It may interfere with cooking
Correct answer: It might harbor bacteria
Jewelry can harbor bacteria and may fall into food, posing contamination risks.
Question 9: How often should food-contact surfaces be cleaned and sanitized?
- Once a day
- Every 2 hours
- Every 4 hours (Correct answer)
- Every shift
Correct answer: Every 4 hours
Food-contact surfaces should be cleaned and sanitized every 4 hours when in constant use.
