Why Cant U Refreeze Meat Once Defrosted. In reality, bread can easily become stale overnight if left uncovered. Why can't you refreeze thawed meat?

Foods that have been defrosted and then refrozen may lose some quality when the cells break down and the meal becomes somewhat watery. Some quality may be lost by defrosting then refreezing foods as the cells. You should also not freeze (or refreeze) any meats that have been sitting at room temperature for longer than 2 hours or at a 90˚ or higher for more than 1 hour.
