CHS Food Safety & Compliance — Questions and Answers
Question 1: What is the temperature danger zone for food safety?
- 41°F to 135°F (5°C to 57°C) (Correct answer)
- 32°F to 100°F
- 50°F to 150°F
- 0°F to 200°F
Correct answer: 41°F to 135°F (5°C to 57°C)
Bacteria multiply rapidly between 41°F and 135°F. Food must not remain in this zone for more than 4 hours cumulatively. Supervisors must ensure proper hot holding (135°F+) and cold holding (41°F or below).
Question 2: What is FIFO and why is it important in food storage?
- First In, First Out: using older inventory before newer stock to prevent spoilage and waste (Correct answer)
- A type of restaurant ordering system
- A food preparation technique
- A financial accounting method only
Correct answer: First In, First Out: using older inventory before newer stock to prevent spoilage and waste
FIFO ensures that older products are used before newer ones, reducing food waste, preventing expired products from being served, and maintaining food quality and safety in storage areas.
Question 3: What are the 'Big 8' food allergens that hospitality staff must know?
- Milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans (Correct answer)
- Only peanuts and shellfish
- Only gluten and dairy
- There are no mandatory allergen requirements
Correct answer: Milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans
The FDA identifies eight major food allergens responsible for most serious allergic reactions. Hospitality staff must know these allergens, prevent cross-contact, and communicate allergen information accurately to guests.
Question 4: What is cross-contamination and how can a supervisor prevent it?
- Transfer of harmful organisms from one surface or food to another, prevented through proper food handling, separate cutting boards, and handwashing (Correct answer)
- Only occurs between raw meat and vegetables
- Cannot be prevented in a commercial kitchen
- Is only a concern in home kitchens
Correct answer: Transfer of harmful organisms from one surface or food to another, prevented through proper food handling, separate cutting boards, and handwashing
Cross-contamination occurs when pathogens transfer between foods, surfaces, or equipment. Prevention includes color-coded cutting boards, proper handwashing, separate storage for raw and cooked foods, and sanitized equipment.
Question 5: What are the critical limits for cooking poultry to safe temperatures?
- 165°F (74°C) internal temperature for at least 15 seconds (Correct answer)
- 145°F for 30 seconds
- 155°F for 15 seconds
- 120°F for 1 minute
Correct answer: 165°F (74°C) internal temperature for at least 15 seconds
All poultry products must reach an internal temperature of 165°F (74°C) for at least 15 seconds to destroy harmful bacteria including Salmonella and Campylobacter, which are common in poultry.
Question 6: What is a food safety management system like HACCP?
- Hazard Analysis and Critical Control Points: a systematic approach to identifying and preventing food safety hazards (Correct answer)
- A recipe management software
- A food cost control system
- A kitchen design standard
Correct answer: Hazard Analysis and Critical Control Points: a systematic approach to identifying and preventing food safety hazards
HACCP identifies potential biological, chemical, and physical hazards in food preparation, establishes critical control points where hazards can be prevented or eliminated, and sets monitoring and corrective action procedures.
