Hi Scarlet!

You may find this link on freezing basics helpful: http://hgic.clemson.edu/factsheets/HGIC3060.htm

Once meat is thawed, it must be used and cannot be refrozen; you're setting yourself up for a nasty case of food poisoning if you do. Meat should be thawed in the refrigerator and not on the countertop as well...or use the microwave if you're in a hurry.
Meat will not keep in the freezer indefinitely; most meats can be safely frozen for up to 6 months, but some have a shorter freezer life. Only buy and freeze as much meat as you can use within the safety zone.

HTH!
