Rules for Refreezing Food

What should you do if your freezer fails? Learn these tricks and tips for what foods are safe to refreeze.

| March/April 1982

Freezing is one of the best methods available to preserve edibles, particularly if food quality and convenience in preparation for storage are of primary importance. Unfortunately, the process does force you to rely upon a fallible electrical appliance. You can almost bank on the fact that sometime, somehow — probably through no fault of your own — that freezer Is going to stop cooling.

Spring storms, for example, sometimes knock out electrical power to entire neighborhoods for days at a time. No matter how the malfunction occurs, there are ways to prevent food spoilage until the problem is solved.

Rules to Remember if the Freezer Breaks

The first thing not to do when your freezer falls is open the door to check on the food. Little thawing will take place during the first 12 hours provided the temperature within had been set at or near 0 degrees Fahrenheit. An unopened, fully loaded freezer can actually keep food safe for up to two days without electricity while a partially loaded chest will be effective for up to one day. (The moral is keep your freezer full, even if you have to use plastic gallon jugs filled with water to take up the empty spaces.) Other rules of thumb: The colder the food at the time of the mishap, the longer and better it will keep and the larger the freezer capacity, the longer the food will stay frozen.

If you're reasonably certain your electrical power will resume within 24 hours, it's probably best to leave your frozen edibles alone. Should It appear that the device will be out of service for longer than one day, it's wise to try to move your goods to a friend's freezer — or to a rental cold-storage locker — for the duration because even a large, fully loaded freezer just might not be able to recover and refreeze the huge quantities of food it contains before spoilage starts to set in. (If you do move your frozen edibles, remember to "insulate" them well for the journey by wrapping items in newspapers and blankets.)

If you don't have any convenient way to move your food, try purchasing some dry ice instead. Twenty-five pounds will maintain a 10-cubic-foot freezer for two to three days. (To determine the necessary amount, just multiply the cubic-foot capacity of your appliance by 2.5.)

You can locate sources of dry ice by consulting the Yellow Pages. Outlets may be listed under ice cream manufacturers and refrigeration suppliers. Or, you might try firms that sell compressed gas. Local dairies, fish markets, or electric utility companies may also be of assistance in locating a source.
