The length of time you can keep items in your freezer:
Soups, stews and casseroles: 2-3 months
Cooked meat 2-3 months
Uncooked steaks, roasts or chops: 4-12 months
Cooked poultry: 4 months
Uncooked poultry: 9-12 months
Freezing does not kill bacteria but just keeps it inactive.
Sometimes frozen fruits can have more nutrients than fresh fruits because they are processed at the ripest point and frozen that way (the more ripe the more they have nutrients)
It is best to avoid refreezing an item, but it is usually ok to refreeze if the item has been out for 2 hours or less.
