May I refreeze the food in the freezer if it thawed or partially thawed?

Yes, the food may be safe­ly refrozen if the food still con­tains ice crys­tals or is at 40°F or below. You will have to eval­u­ate each item sep­a­rate­ly. Be sure to dis­card any items in either the freez­er or the refrig­er­a­tor that have come into con­tact with raw meat juices. Par­tial thaw­ing and refreez­ing may reduce the qual­i­ty of some food, but the food will remain safe to eat.
