What are the safest ways to thaw foods? There are three safe ways to thaw food: in the refrigerator, in cold water, and in the microwave. Planning ahead is the key when refrigerator thawing because of the lengthy time involved. Even small amounts of frozen food--such as a pound of ground meat--require a full day to thaw.
The U. S. Dept. of Agriculture (USDA) advises: Once food is thawed in the refrigerator, it is safe to refreeze it without cooking, although there may be a loss of quality due to the moisture lost through thawing.After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods.If previously cooked foods are thawed in the refrigerator, you may refreeze the unused portion. Freeze leftovers within 3-4 days.O NOT thaw meat at room temperature, such as on the kitchen counter. Safety will depend on whether the raw product was handled properly before it was frozen, refrozen shortly after it was thawed, cooked to a safe temperature when it is eaten and handled safely if there are any leftovers.
