Study Notes

Refrigerator (Fridge)

Recommended temperature range: 1°C to 4°C (34°F to 39°F)
This temperature range inhibits the growth of most bacteria and slows down spoilage processes.
Maintaining a consistent temperature is crucial for food safety and quality.
Avoid placing hot food directly into the refrigerator as it can raise the internal temperature of the refrigerator and affect other stored foods.

Freezer

Recommended temperature range: -18°C (-0.4°F) or below
This extremely low temperature prevents bacterial growth and stops nearly all biological activity.
Frozen foods should be stored completely sealed to prevent freezer burn, or the growth of freezer-related bacteria (particularly important for certain foods).
Different foods have varying freezing time requirements.

Cooking Minced Beef

Safe internal temperature for minced beef: 71°C (160°F)
This ensures that any harmful bacteria are eliminated.
Proper cooking time and temperature are essential; improper cooking may result in foodborne illnesses.
Visual inspection of the colour change may be unreliable. Use a food thermometer for an accurate measurement.

Holding Food on a Buffet

Recommended temperature: Below 57°C(135°F) or Above 60°C(140°F)
Temperatures between these ranges should be maintained to avoid bacterial growth which can multiply quickly at intermediate temperatures.
Use food warming equipment that keeps food at this safe temperature range.
Regular checks of temperatures to verify the temperature range of food.

Reheating Leftovers

Safe reheating temperature: 74°C (165°F)
This is the minimal, recommended temperature to kill bacteria and prevent foodborne illnesses, although some foods (e.g., milk) may require higher temperatures to ensure full safety.
Ensure food is heated thoroughly to the appropriate temperature throughout. This can help to minimize the chance of any safety risk.

Pasteurization of Milk

Temperature needed for pasteurization: 72°C (161.6°F) for 15 seconds.
This process eliminates harmful bacteria in milk, making it safe for consumption.
Longer heating times and higher temperatures may affect the flavor or nutritional value of the milk.
Specific regulations and standards exist for pasteurization procedures.
