If your freezer temperature rises above -15°C, here's what you need to do:
If you don't have access to another freezer, you'll need to follow these steps:
Common misunderstanding: Once food begins to defrost, it is safe to refreeze it if it still feels cold.
Refreezing defrosted food can lead to significant quality degradation and increases the risk of bacterial growth. It is important to use defrosted food within 48 hours if kept in the fridge, and never refreeze it once it has begun to thaw.
To prevent future temperature issues:

The ideal freezer temperature should be -18°C (0°F) or below to halt all bacterial activity, ensuring food safety and preventing spoilage.
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.
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.
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).
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.
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.
Fresh meat should ideally be used within one month of freezing to maintain optimal quality.
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.
You should conduct weekly checks on the freezer's condensers, vents, seals, and lids to ensure they are clean and in good condition.
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, 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.
Grey spots on frozen food, known as freezer burn, occur when air reaches the food's surface, causing dehydration and oxidation.
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.
When labelling frozen food, it's important to include three key pieces of information: the production date, a use-by date (generally one month from production), and the allergens present in the food.
