Describe the correct storage of different foods and explain how temperature control through chilling, freezing and reheating keeps food safe

What this dot point is asking

The syllabus wants you to describe how different foods should be stored and explain how temperature control keeps food safe and fresh. The central idea is that correct storage, above all keeping food cold, denies bacteria the warmth they need to multiply, so good storage is the everyday application of the danger-zone rule.

The answer

Storing different foods

• Raw meat, poultry and fish: in covered containers on the bottom shelf of the fridge, so juices cannot drip onto other foods.
• Cooked and ready-to-eat foods: on upper shelves, above and away from raw foods, covered.
• Dairy and eggs: in the fridge, covered, used by their dates.
• Fruit and vegetables: in the salad drawer, where it is slightly less cold.
• Dry and canned goods: in a cool, dry cupboard, off the floor, with older stock used first.
• Frozen food: in the freezer below $-18\ ^\circ\text{C}$.

Temperature control and the cold chain

Temperature is the main tool for safe storage:

• Fridge below $5\ ^\circ\text{C}$: slows bacterial growth so chilled food keeps for a few days.
• Freezer below $-18\ ^\circ\text{C}$: stops bacterial growth (but does not kill bacteria), so food keeps for months.
• The cold chain is keeping chilled and frozen food cold without a break, from shop to home, so it never warms into the danger zone. Buy cold items last, carry them in a cool bag, and refrigerate them as soon as you get home.

Fridge rules

Keep the fridge cold and not overfilled so cold air can circulate; cover all foods to prevent drying, cross-contamination and odour transfer; check the temperature; and rotate stock so older food is used first.

Freezing and thawing safely

Freeze food while it is fresh, in dated portions. Thaw frozen raw meat fully in the fridge, not at room temperature, so the outside does not warm into the danger zone while the inside is still frozen. Never refreeze thawed raw food, and cook thawed food promptly.

Reheating

Reheat food until piping hot, above $75\ ^\circ\text{C}$ throughout, and only once. This kills bacteria that grew during storage and avoids repeated trips through the danger zone.

Examples in context

Example 1. Storing chilled chicken from the supermarket. Carrying chicken home in a cool bag in Singapore's heat and putting it straight onto the fridge's bottom shelf keeps the cold chain intact and stops its juices contaminating other food. Leaving it warm in a hot car would let bacteria multiply before it is even cooked.

Example 2. Thawing meat for dinner. Moving frozen meat to the fridge the night before lets it thaw fully while staying cold, ready to cook safely. Thawing it on the kitchen counter in the warmth would let the surface enter the danger zone while the centre is still icy, risking food poisoning.

Try this

• Cue. State where raw meat and cooked food should go in a fridge and why. Recall raw meat low and covered to stop drips, cooked food above, away from raw.
• Cue. Give the safe temperatures for a fridge and a freezer. Recall below $5\ ^\circ\text{C}$ for the fridge and below $-18\ ^\circ\text{C}$ for the freezer.
• Cue. Explain the cold chain and one way to keep it unbroken. Recall keeping food cold from shop to home, using a cool bag and refrigerating at once.
