Safe Thawing

Food should never be thawed at room temperature. Three acceptable ways to safely thaw foods are: in a refrigerator, in a microwave or immersed in cold water.

Cool Tip

If the food has been in the refrigerator while thawing and is still partially frozen (ice crystals present) then it can be refrozen. If the food has been thawed, the safest thing to do is cook the fish, meat or poultry before refreezing. However, if the food was thawed out of the fridge or in the microwave, then do not refreeze. Parts of the surface or interior of the food will have been exposed to temperatures above 4ºC for a period of time. Thawing and refreezing anything will affect the quality of the food. Ice crystals damage cell structure and freezing may remove moisture from the food. Never thaw food on the counter. Foods thawed in a microwave need to be cooked immediately.
