When labelling frozen food, you need to include three key pieces of information: the date of production, a use-by date (one month from production), and clearly mark any allergens present in the food. Make sure food is properly portioned and thoroughly wrapped before freezing.

Common misunderstanding: As long as frozen food is packaged securely, labelling isn't necessary.

While secure packaging is crucial for preventing freezer burn and contamination, proper labelling is equally important for traceability and food safety. Labels provide essential information such as production and expiration dates, which help avoid food spoilage and ensure that allergens are clearly identified, protecting consumers with allergies.

Common misunderstanding: Allergens don't need to be labeled on frozen food as freezing neutralises allergens.

Freezing does not neutralise allergens. Allergens remain present and can still trigger reactions in sensitive individuals. Therefore, it is imperative to clearly label any allergens on frozen food packaging to ensure consumer safety.

What happens if I forget to label something in the freezer?

If food items aren't properly labeled, a manager or responsible person will need to assess whether the food should be discarded. It's always better to err on the side of caution - if you're unsure about when something was frozen or what allergens it contains, it's safer to dispose of it.

Common misunderstanding: It's safe to rely on the appearance and smell of frozen food to determine its safety if it's not labeled.

Appearance and smell are not reliable indicators of frozen food safety. Freezing can preserve food's outward appearance and the development of spoilage odors may be inhibited. Without proper labelling, it's impossible to accurately assess the safety of the food, including its age and potential allergen content.

Common misunderstanding: Once food is frozen, it doesn't matter how long it stays in the freezer as it's indefinitely safe.

While freezing preserves food and halts bacterial growth, it does not stop food quality from degrading over time. Each type of food has a recommended freezing duration to maintain its best quality. Beyond this period, although the food may still be safe to eat, its taste and texture can deteriorate significantly.

Should I label food differently if it's raw meat versus cooked food?

While the basic labelling requirements are the same, it's important to note that raw meat should ideally not be frozen if possible. However, if you must freeze raw meat, ensure it's adequately wrapped, properly date labeled, and used within one month. Make sure the meat is properly chilled (below 5°C) before freezing to ensure better quality preservation.

What's the correct temperature for a freezer?

The ideal freezer temperature should be -18°C (0°F) or below to halt all bacterial activity, ensuring food safety and preventing spoilage.

How often should I check the freezer temperature?

You should check and record freezer temperatures twice per day to ensure they are maintained at -18°C (0°F) or below. Regularly recording this data helps in maintaining optimal food safety conditions.

Can I refreeze food that has started to defrost?

No, you should never refreeze food that has started to defrost. Once food begins to defrost, it should either be used immediately or discarded to avoid safety risks.

What do I do if the freezer temperature goes above -15°C?

If your freezer temperature rises above -15°C, follow these steps: 1. Wait one hour and check the temperature again. 2. If it remains above -15°C, move all food to another freezer. 3.

How do I know if frozen food has gone bad?

To determine if frozen food has gone bad, look for these signs: grayish-brown leathery spots indicating freezer burn, improper wrapping, and storage above -18°C (0°F).

Should I defrost the freezer manually or wait for auto-defrost?

If your freezer has an auto-defrost feature, it is recommended to use it as this method is the most efficient at maintaining the freezer.

Can I still serve food with freezer burn?

If there's only slight freezer burn, you can cut away the affected areas either before or after cooking. For heavily freezer-burned food, it is best to discard it due to quality concerns.

How long can I keep meat in the freezer?

Fresh meat should ideally be used within one month of freezing to maintain optimal quality.

What's the procedure if the freezer breaks down?

If your freezer breaks down, you should: 1) Check if the food inside is still frozen solid. If yes, quickly transfer it to another freezer.

How often should I clean the freezer?

You should conduct weekly checks on the freezer's condensers, vents, seals, and lids to ensure they are clean and in good condition.

What should I check during weekly freezer maintenance?

During weekly freezer maintenance, ensure to check: 1. Condensers for cleanliness and unblocked paths, 2. Vents to ensure they are clear of debris and allow proper airflow, 3.

If the power goes out, how long will food stay frozen?

If the power goes out, the duration that food will stay frozen depends on not opening the freezer door. If the food remains hard and is covered in ice, it can be transferred to another freezer.

What do the grey spots on frozen food mean?

Grey spots on frozen food, known as freezer burn, occur when air reaches the food's surface, causing dehydration and oxidation.

How can I tell if my freezer is overloaded?

You can determine if your freezer is overloaded by checking for inadequate space around the interior and back of the unit to allow for air circulation.
