Defrosting beef in the refrigerator is the safest method as the temperature will not exceed 5℃ when microbial activity increases. If you don’t have time to wait, microwave defrosting is a great backup, but care should be taken to ensure the temperature does not rise above 5℃, preventing the risk of food poisoning.

Safe ways to defrost beef

To check that your beef is fully defrosted, prod with a skewer or fork. If it meets any resistance other than the normal meat texture, it’s still frozen. Ice crystals or meat rigidity are also signs that thawing is incomplete.

Defrosting beef in the refrigerator

Time taken: 12-24 hrs

Defrosting beef in the refrigerator is the safest method to maintain a consistent temperature below 5°C, inhibiting bacterial growth. However, it is slower than other methods taking 12-24 hours depending on the size and density of the joint or pieces.

Defrosting beef in the microwave

Time taken: 10-15 mins per KG (check the user manual)

The quickest way to defrost beef is in the microwave. Check your user manual and use the defrost setting and time recommended. Defrost small quantities at a time and rotate the meat frequently to ensure even thawing. It’s important to check the beef doesn't start cooking - if it does you must continue to cook through completely. Lack of precise temperature control is an issue with microwave defrosting so monitor the process carefully.

Defrosting beef in cold water

Time taken: 1 - 3 hrs

Submerging wrapped beef in cold water is faster than defrosting in the refrigerator. It takes 1-3 hours depending on the meat size and density but requires regular water changes every 30 minutes to encourage a gradual reduction in temperature.

This method is not advised if the room temperature is above 32℃ as the water could become too hot and promote microbial growth. If this happens, throw the beef out and don’t eat it. Hot water should never be used for this same reason.

The beef should remain wrapped to prevent water penetration which could affect the taste, texture and nutrient content.

Unsafe ways to defrost beef

Do not defrost beef at room temperature

Defrosting beef at room temperature is dangerous. It might speed the thawing process up but the surface of the meat is exposed to variable room temperatures which can exceed 5℃. If this happens it allows bacteria to grow, increasing the risk of food poisoning.

Do not defrost beef in the oven

Oven defrosting is not recommended for raw beef as it can lead to uneven defrosting and potential bacterial growth.
