Store Food Safely
The principles
Safe storage protects food from contamination and from the temperature danger zone, generally described as 5°C to 60°C, where bacteria multiply fastest. Candidates must know the 2-hour/4-hour rule for ready-to-eat food that has been in the danger zone: under 2 hours, refrigerate or use; 2 to 4 hours, use immediately and do not return to refrigeration; over 4 hours, discard. This rule is a common question target.
Cold, frozen and dry storage
Cold storage should run at 5°C or colder, freezers at around -18°C or colder, and dry stores cool, dry and pest-free. Store raw food below cooked and ready-to-eat food so drips cannot contaminate. Keep food covered, labelled and dated, and apply first in, first out and date coding. Do not overload fridges, because airflow is what keeps food cold.
Traps that appear in questions
- Storing raw meat above ready-to-eat food, or assuming cling wrap makes this safe.
- Believing freezing kills bacteria. It stops growth; it does not sterilise.
- Defrosting on the bench at room temperature instead of in the fridge, in a microwave for immediate cooking, or under running water in a sealed bag.
- Using smell or appearance to judge safety. Pathogens such as Listeria and Salmonella do not reliably change smell, taste or look.
- Re-refrigerating food that has already spent 2 to 4 hours in the danger zone.
- Ignoring date marking and high-risk foods such as cooked rice, cooked pasta, raw egg products, seafood and soft cheeses.
Worked example / rule of thumb
A tray of cooked chicken sits on the bench for 3 hours during a busy lunch. Rule of thumb: 2 hours is the line for returning to the fridge; 4 hours is the line for the bin. At 3 hours the chicken must be used immediately or discarded, and it must not go back into the cool room. Record the decision and tell your supervisor.
