The correct answer is 'A systemic analysis of all steps and regular monitoring of the control points'

Key Points

• HACCP System:
  • HACCP stands for Hazard Analysis and Critical Control Points.
  • It is a systematic approach to food safety that identifies, evaluates, and controls hazards which are significant for food safety.
  • The primary objective of HACCP is to ensure food safety by preventing contamination through a proactive approach.
  • The system involves a detailed analysis of all steps in the food production process and regular monitoring of control points to prevent or reduce hazards.

The correct answer is 'Buffet service'

Key Points

• Buffet service:
  • Carveries are a type of buffet service where meats are roasted and carved to order in front of the guests.
  • This service style allows guests to choose from a variety of meats, vegetables, and sides, promoting a casual and interactive dining experience.
  • Buffet service is characterized by its self-service format, offering a wide selection of dishes displayed on a buffet table.

Additional Information

• Silver service:
  • Also known as service à la russe, silver service involves dishes being served from the left, while drinks and plated meals are served from the right.
  • This type of service is more formal and requires service staff to portion and serve food at the table.
• Plate service:
  • Also known as American service, in plate service, food is plated in the kitchen and served directly to guests.
  • This service style is efficient and commonly used in casual dining settings.
• Cafeteria service:
  • In cafeteria service, guests typically carry a tray along a line, choosing from various pre-prepared dishes.
  • It is a quick service method often used in institutional settings like schools and hospitals.

The correct answer is 'Water'

Key Points

• MPN test:
  • MPN stands for Most Probable Number, a microbiological technique used to estimate the number of viable microorganisms in a sample.
  • It is commonly used for water quality testing to detect coliform bacteria, which indicates possible contamination by pathogens.
  • The test involves multiple serial dilutions and incubations to statistically estimate the concentration of microorganisms.

Additional Information

• Meat:
  • While microbial testing is essential for meat safety, the MPN test is not typically used for this purpose.
  • Other methods, like plate counts and PCR, are more commonly employed for meat analysis.
• Blood:
  • Blood tests generally focus on cell counts, biochemistry, and serology, not on MPN.
  • Microbial contamination in blood is usually detected using blood culture techniques.
• Fish:
  • Fish quality is often assessed through sensory evaluation, chemical tests, and specific microbial tests, not MPN.
  • Methods such as total viable count (TVC) and histamine testing are more relevant for fish.

The correct answer is Cooking food to the appropriate temperature.

Key Points

The correct answer, A) Cooking food to the appropriate temperature, is vital for microbiological safety because high temperatures effectively kill harmful bacteria and pathogens that can cause foodborne illnesses. Different foods have specific safe cooking temperatures, which ensure that any potential pathogens are destroyed. For instance:

• Poultry should be cooked to an internal temperature of 165°F (75°C) to eliminate bacteria like Salmonella.
• Ground meats should reach at least 160°F (71°C) to ensure safety.
• Beef, pork, lamb, and veal steaks, chops, and roasts should be cooked to at least 145°F (63°C) and allowed to rest for three minutes before slicing.

By cooking food to these recommended temperatures, you significantly reduce the risk of foodborne illnesses. This practice is a fundamental aspect of food safety and helps protect consumers from the dangers posed by undercooked or improperly handled food.

Additional Information

B) Storing food at room temperature: This practice is unsafe because it allows bacteria to grow rapidly. Many harmful pathogens thrive in the "danger zone," which is between 40°F and 140°F (4°C to 60°C). Storing perishable foods at room temperature can lead to bacterial growth and increase the risk of foodborne illnesses.

C) Using the same cutting board for raw meat and vegetables: This practice increases the risk of cross-contamination. Bacteria from raw meat, such as Salmonella or E. coli, can transfer to vegetables that will be consumed raw, potentially leading to foodborne illnesses. It's essential to use separate cutting boards for raw meat and ready-to-eat foods to prevent this risk.

D) Keeping food uncovered in the refrigerator: Leaving food uncovered can expose it to airborne contaminants and bacteria, leading to spoilage and increased risk of foodborne illness. Properly covering food helps protect it from contamination and maintains its quality.

The other options represent unsafe practices that could contribute to the spread of bacteria and increase the risk of foodborne illnesses, while cooking food to the appropriate temperature directly mitigates these risks.

The correct answer is Melting point.

Key Points

The melting point is the temperature at which a solid turns into a liquid. In the context of food, this property is significant because it influences how ingredients behave during cooking and food preparation. For example:

• Chocolate: Understanding the melting point of chocolate is crucial for tempering, which ensures a smooth texture and glossy finish when it hardens. If chocolate is overheated, it can seize and become unusable.
• Butter: The melting point of butter affects how it incorporates into recipes. For instance, melted butter can blend more easily into batters, while cold butter is often used in pastry making to create flaky textures.

Physical properties like melting point are important because they directly impact how food is prepared, its texture, and the overall quality of the final dish. In contrast, the other options—nutritional value, flavor compounds, and shelf life—are more related to the chemical composition and biological aspects of food rather than its physical characteristics.

The correct answer is a - iv, b - iii, c - i, d - ii.

Key Points

a - Selenium - Sea foods

Selenium is a trace mineral that is commonly found in seafood. It's important for various bodily functions, including antioxidant activity.

b - Vitamin E - Sunflower seeds

c -Flavonoids - Green leafy vegetables
Flavonoids are a group of plant compounds that have antioxidant properties, and they are found in high amounts in green leafy vegetables, contributing to their health benefits.

d -Lycopene - Tomato
Lycopene is a powerful antioxidant predominantly found in tomatoes. It is known for its potential health benefits, including reducing the risk of certain diseases.

The correct answer is Both I and II.
