No, you should never refreeze food that has started to defrost. Once food begins to defrost, it must either be used immediately or discarded. If you have partially defrosted food, you should move it to a fridge and use it within 48 hours.
This is particularly important for items like ice cream which must be used immediately or discarded if they've started to defrost - these items cannot be refrozen under any circumstances.
Common misunderstanding: Refreezing defrosted food is safe as long as it was refrigerated.
Refreezing defrosted food, even if it was refrigerated, is not advisable because the quality and safety of the food may be compromised. Each freeze-thaw cycle allows bacteria to grow and can degrade the texture and flavour of the food.
Common misunderstanding: You can refreeze food if it was thawed in a microwave.
While a microwave can quickly thaw food, it can also rapidly bring portions of the food to temperatures where bacteria thrive. Therefore, refreezing food thawed in a microwave is not recommended unless it has been cooked immediately after thawing.
If the food still feels completely hard and is still covered in ice, you can move it to another freezer unit. However, if there's any softening or the ice is melting, you'll need to treat it as defrosting food and either use it quickly or dispose of it.
Common misunderstanding: Food with ice crystals is always safe to refreeze.
The presence of ice crystals may indicate that the food is still partially frozen, but it doesn't guarantee safety for refreezing. If the food has begun to thaw at any point, especially in an uncontrolled environment, it should not be refrozen without cooking first.
Common misunderstanding: As long as food is below freezing temperature, it can be moved between freezers without concern.
While moving food between freezers can be safe, temperature fluctuations during the transfer could lead to partial thawing. It is crucial to minimize the time food spends outside of a controlled freezing environment to prevent bacterial growth.
If you're unsure about how long food has been defrosting, it's always better to err on the side of caution and discard it. This is especially important for raw meat and poultry - if there's any chance of cross-contamination, don't take the risk. The only exception would be if you can use the raw meat or poultry immediately in cooking.
Common misunderstanding: If food looks and smells fine, it can be safely refrozen even if you're unsure of the defrosting duration.
Visual and smell assessments cannot reliably determine food safety, especially for bacteria that do not affect appearance or odour. If the duration of defrosting is uncertain, it is safer to discard the food to avoid potential food-borne illnesses.
Common misunderstanding: As long as you refreeze food within a few hours of defrosting, it remains safe.
The safety of refreezing is not solely time-dependent but also relates to temperature exposure during defrosting. Even a few hours at room temperature can allow bacteria to proliferate, rendering the food unsafe to refreeze without cooking.

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.
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.
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.
