I. Choose the Best Answer (MCQs)
1. The temperature danger zone for food safety is: (a) 0°C–5°C (b) 5°C–60°C (c) 60°C–100°C (d) Below 0°C
Answer(b) 5°C–60°C Danger zone (5°C–60°C): bacteria multiply most rapidly in this temperature range. To keep food safe: hold cold foods below 5°C (refrigerator: 1-4°C) and hot foods above 60°C. Never leave cooked food in the danger zone for more than 2 hours.
2. FIFO in food storage means: (a) First In, First Out — older products are used before newer ones (b) First In, Frozen Out (c) Fresh Items First Only (d) Fixed Inventory First Order
Answer(a) First In, First Out — older products are used before newer ones FIFO: stock rotation principle. New deliveries placed behind existing stock; front stock used first. Prevents food spoilage and waste. Especially important for perishable items (dairy, meat, fresh produce).
3. An à la carte menu is one where: (a) A fixed price covers all courses (b) Each item is individually priced and guests choose what they want (c) The chef decides the menu daily (d) Only vegetarian options are available
Answer(b) Each item is individually priced and guests choose what they want À la carte (French: "from the menu"): each dish is separately priced; maximum customer choice; takes longer to prepare and serve. Table d'hôte ("host's table"): fixed price for set courses with limited choices; faster service; popular in canteens and mid-range restaurants.
4. The purpose of Hazard Analysis in HACCP is to: (a) Hire safety officers (b) Identify potential biological, chemical, and physical hazards in food production (c) Design the kitchen layout (d) Calculate food cost
Answer(b) Identify potential biological, chemical, and physical hazards in food production Hazard types in HACCP: 1. Biological: bacteria (Salmonella, E. coli, Listeria), viruses, parasites. 2. Chemical: pesticide residue, cleaning chemicals, food additives. 3. Physical: glass, metal, bone fragments, plastic. Hazard analysis is the first step in designing a safe food production system.
5. Which food service style is most appropriate for large banquets where speed of service is priority? (a) English service (b) French service (c) American (Plated) service (d) Russian service
Answer(c) American (Plated) service American/plated service: food plated in kitchen and served to guests. Fastest service style; suitable for large numbers. English service: food served from large dish by waiter; family-style. French service: food prepared or finished tableside; most elaborate, slowest. Russian service: food plated on silver platter; portioned tableside.
6. Cross-contamination in food service means: (a) Serving food from one cuisine to another (b) Transfer of harmful bacteria from one food to another through contact, utensils, hands, or surfaces (c) Cooking different types of food together (d) Mixing hot and cold foods
Answer(b) Transfer of harmful bacteria from one food to another through contact, utensils, hands, or surfaces Cross-contamination prevention: use colour-coded chopping boards (red: raw meat, green: vegetables, yellow: poultry, blue: fish), wash hands between handling raw and cooked food, separate storage of raw and cooked foods, clean and sanitise surfaces regularly.
7. The standard hand-washing technique as per WHO guidelines takes approximately: (a) 5 seconds (b) 20 seconds (c) 40–60 seconds (d) 3 minutes
Answer(c) 40–60 seconds WHO 6-step hand-washing: 1. Wet hands and apply soap. 2. Rub palms together. 3. Rub back of hands. 4. Interlace fingers. 5. Rub thumbs. 6. Rub fingertips. Takes 40–60 seconds with soap; alcohol hand rub: 20-30 seconds. Critical times: before food preparation, after handling raw meat, after toilet use, after touching waste.
II. Short Answer Questions
Q1. Explain the importance of menu planning in food service management.
Answer
Menu planning: the process of selecting and organising food items that a food service establishment will offer.
Factors to consider: 1. Customer profile: Age, dietary needs, preferences, cultural/religious requirements (vegetarian, halal, jain). 2. Nutritional balance: Meals should meet RDA; particularly important in institutional catering (schools, hospitals). 3. Food cost: Food cost % = (food cost/sales) × 100; standard 28-35%. Menu must be profitable. 4. Seasonal availability: Fresh seasonal produce → better quality and lower cost. 5. Staff capability: Kitchen team skills and equipment must match menu complexity. 6. Variety: Colour, texture, flavour, cooking method variety → appealing menus.
Types of menus:
- Table d'hôte: fixed price, set courses.
- À la carte: individually priced items.
- Cyclical: repeating menu cycle (schools, hospitals); consistent, reduces planning effort.
- Buffet: wide variety, self-service.
Q2. What are the personal hygiene rules for food handlers?
Answer
Food handler hygiene rules are critical to prevent foodborne illness:
Body hygiene:
- Shower/bathe daily; wear clean uniform.
- Hair: tied back or covered with hair net.
- No perfume (can contaminate food odour); no excessive jewellery.
Hands:
- Wash hands: before work, after toilet, after handling raw meat/rubbish/chemicals, after sneezing.
- Keep nails clean and short; no nail polish.
- Cover cuts and sores with blue waterproof plasters (visible if they fall in food).
Health:
- Report illness (vomiting, diarrhoea, skin infections, respiratory illness) to supervisor; do not handle food.
- Get relevant vaccinations (e.g., Hepatitis A in some countries).
Behaviour:
- No eating or chewing gum while preparing food.
- No smoking in food preparation areas.
- No touching face, hair while handling food; then wash hands.
- No spitting in the kitchen.
