You need to ensure there's adequate space around all sides of items in your fridge, particularly at the back and sides of the unit. This allows cold air to flow freely throughout the fridge, preventing hot spots and maintaining consistent temperatures. Never stack items right against the walls of the fridge. Overcrowding can lead to temperature fluctuations which increases the risk of bacterial growth in your food items.

What about between shelves - how much space do I need there?

You should leave enough space between shelves to allow cold air to move freely up and down through the fridge. If items are touching the shelf above them, this blocks proper air circulation. A good rule is to ensure there's visible space between your stored items and the shelf above.

Common misunderstanding: As long as items fit, they can touch the shelf above without affecting cooling efficiency.

When items touch the shelf above, they can block the airflow needed for even cooling throughout the fridge. This can lead to temperature variations that affect food quality and safety. Always ensure there is sufficient space between stored items and the shelf above to promote optimal air circulation.

Common misunderstanding: Items on higher shelves don't need as much space because cold air naturally sinks.

While it's true that cold air tends to sink, proper circulation throughout the fridge is essential to ensure all areas are evenly cooled. Blocking the space between shelves can create isolated zones with inadequate cooling, potentially compromising food safety.

Does it matter if items touch each other on the same shelf?

Yes, it's important to maintain some space between items even on the same shelf. When items are packed too tightly together, it creates pockets where cold air can't reach effectively. This can lead to uneven cooling and potential temperature danger zones. Make sure there's enough room for air to flow between containers and packages.

Common misunderstanding: As long as the fridge door closes, it doesn't matter if items touch on the shelf.

Closing the fridge door is not an indicator of proper air circulation. When items touch, they can reduce airflow, which is essential for consistent cooling. This can result in uneven temperatures and potential food safety hazards. Ensuring items are spaced out is important for maintaining optimal fridge performance.

Common misunderstanding: The type of packaging doesn't affect air circulation within the fridge.

Packaging type can significantly impact air circulation. For example, tightly wrapped items or sealed containers can obstruct airflow more than loosely packaged items. Opt for storage solutions that allow air to circulate freely to maintain consistent temperatures and prevent spoilage.

How often do I need to check fridge temperatures?

Fridge temperatures should be checked and recorded twice per day or once per shift. Regular checking helps identify any issues early, preventing potential food safety problems.

What's the maximum time food can be above 8°C before we have to throw it away?

Food that has been above 8°C must be discarded after 4 hours. This rule is strictly applicable only once and cannot be applied multiple times for periods under 4 hours each.

What should I do if I find the fridge temperature is over 8°C?

If you discover that the fridge temperature is above 8°C, you should immediately take the following steps: (1) Check the actual food temperature using a clean, sanitised probe thermometer.

Where exactly should raw meat be stored in the fridge

Raw meat should always be stored on the lowest shelf of the fridge to prevent drips from contaminating other foods.

Do I need to record fridge temperatures even if they're normal?

Yes, it is necessary to record all fridge temperatures, even when they are within the normal range.

Can I use cling film to cover food in the display fridge?

Yes, you can use cling film to cover food in the display fridge as long as it is food-grade wrapping. Ensure that your display fridge also has proper sneeze guards or screening to protect the food.

How long can we keep batch-cooked food in the fridge?

Batch-cooked food should be consumed within three days, including the day it was prepared. For instance, if the food is cooked on Tuesday, it should be used by the end of Thursday.

Should I store fresh fish in a separate fridge from other items?

Ideally, fresh fish should be stored in a separate fridge set at a temperature below 3°C to meet its specific cooling requirements.

How often should we clean the fridge seals?

Fridge seals should be inspected weekly to check their condition and cleanliness. This regular maintenance helps keep the fridge working efficiently.

If the fridge breaks down overnight, do we have to throw everything away?

If the duration of the fridge outage overnight is unknown and you cannot verify that the food temperature has remained below 8°C using a probe thermometer, it is safer to discard all the food and record it as waste. However, if the temperature checks confirm the food is below 8°C, you can safely transfer it to another working fridge. This approach prevents unnecessary waste while ensuring compliance with food safety standards.

If food in the fridge is at 7°C, how often should we check it?

When food is stored in a fridge and the temperature is between 6-8°C, it should be checked hourly to ensure it doesn't exceed 8°C.

Can we put hot food straight into the fridge?

No, you should not put hot food directly into the fridge. Doing so can raise the temperature inside the fridge, potentially affecting other stored foods and causing temperature fluctuations.

What happens if we don't have another fridge to move food to during a breakdown?

If you don't have access to an alternative refrigeration unit during a breakdown, you must use the affected food within 4 hours if the temperature rises above 8°C.

What should I do if I notice the fridge seal is damaged?

If the fridge seal is damaged, it's important to address the issue immediately as it can lead to warm air entering the fridge and cause temperature fluctuations.
