A. 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 defrosting. After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods.And if previously cooked foods are thawed in the refrigerator, you may refreeze the unused portion.

When defrosting frozen foods, it's best to plan ahead and thaw food in the refrigerator where food will remain at a safe, constant temperature â 40 Â°F or below. There are three safe ways to defrost food: in the refrigerator, in cold water, and in the microwave.Refrigerator Thawing Planning ahead is the key to this method because of the lengthy time involved. A large frozen item like a turkey requires at least a day (24 hours) for every 5 pounds of weight.he rule of thumb is for a piece of meat to spend no more than 4 hours (cumulative) in the danger zone (above 40 degrees F). A thin piece of steak won't take that long to defrost, so it's relatively safe to defrost on the counter and then cook immediately.
