A rule of thumb for defrosting frozen meat in the fridge is to allow one day for every five pounds (2.27 kilograms). Defrosted meat is safe to refreeze as long as it was thawed in the refrigerator.

Theoretically, when meat is frozen correctly and maintained at the optimal freezing temperature, it should stay good forever.
