Cooking Lessons Food Safety and Sanitation 4 — Questions and Answers
Question 1: What does a bulging or swollen can of food most likely indicate?
- Possible Clostridium botulinum contamination (Correct answer)
- The food inside is extra fresh
- High vitamin content
- Normal pressure changes from shipping
Correct answer: Possible Clostridium botulinum contamination
Gas produced by Clostridium botulinum can swell cans, and the food must never be eaten.
Question 2: What is the safe way to cool a large pot of hot soup for storage?
- Let it sit at room temperature until fully cool, then refrigerate
- Divide it into shallow containers or use an ice bath to cool it quickly (Correct answer)
- Place the whole hot pot directly into a packed refrigerator
- Leave the covered pot on the counter overnight
Correct answer: Divide it into shallow containers or use an ice bath to cool it quickly
Shallow containers and ice baths cool food through the danger zone quickly and safely.
Question 3: To what internal temperature should leftovers be reheated before serving?
- 120°F (49°C)
- 140°F (60°C)
- 100°F (38°C)
- 165°F (74°C) (Correct answer)
Correct answer: 165°F (74°C)
Reheating leftovers to 165°F destroys bacteria that may have grown during storage.
Question 4: Why should a food thermometer be calibrated regularly?
- To make it heat food faster
- To sterilize the probe
- To ensure temperature readings are accurate (Correct answer)
- To keep the battery from dying
Correct answer: To ensure temperature readings are accurate
An uncalibrated thermometer can give false readings, leading to undercooked or unsafe food.
Question 5: Which of these is an example of a physical contaminant in food?
- Mold growing on bread
- Cleaning chemical residue on a counter
- Salmonella bacteria on chicken
- A fragment of broken glass in a dish (Correct answer)
Correct answer: A fragment of broken glass in a dish
Physical contaminants are foreign objects like glass, metal shavings, or hair in food.
Question 6: A guest with a severe peanut allergy orders a dish. What must the kitchen do?
- Prepare the dish with cleaned equipment and utensils free of any peanut contact (Correct answer)
- Simply pick visible peanuts out of the finished dish
- Cook the dish at a higher temperature to destroy the allergen
- Add extra sauce to dilute any peanut traces
Correct answer: Prepare the dish with cleaned equipment and utensils free of any peanut contact
Allergens are not destroyed by cooking, so preventing any cross-contact is the only safe approach.
Question 7: How should chemicals like cleaners and sanitizers be stored in a kitchen?
- Away from food, in labeled containers, in a designated area (Correct answer)
- In unmarked spray bottles near the prep sink
- Mixed together to save storage space
- On the shelf above dry food for easy access
Correct answer: Away from food, in labeled containers, in a designated area
Chemicals must be labeled and stored separately from food to prevent chemical contamination.
