The colder the foods, the longer they will keep. Do not open a freezer if the power fails. Opening the doors hastens thawing.
Several factors influence the speed of thawing.
The food in a fully loaded freezer will last longer than a half filled one. Pile the foods together to keep the foods frozen longer. Group meat and poultry to one side of the freezer or on a tray so that if they start to thaw the meat juices will not get onto other foods. Frozen meat will stay frozen longer than a freezer with lots of baked items. A large freezer will keep the foods frozen longer than a small one.
