Are You Ready for an Emergency?

Kathy Brandt

Emergency preparedness, crisis management, and disaster planning are common terms that conjure up pictures of unpleasant situations. As much as we don’t want to think about situations like power outages, floods, fire or water disruption, it’s a fact of business to plan and prepare for the unexpected. There are resources available to help you plan for the unexpected.

Food Safety During Power Outages in Food Establishments

Follow these recommendations for food safety during a power outage of more than two hours. The goal of these recommendations is to protect consumers from unsafe food and minimize product loss.

When there is a power outage:

Maintain Proper Temperatures

Food in refrigerators should be safe as long as the power is out no more than four to six hours. Leave the door closed; every time you open it, needed cold air escapes, causing the foods inside to reach unsafe temperatures. Discard any potentially hazardous food that has been above 41°F for four hours or more.

Leave the freezer door closed. A full freezer should keep food safe about two days and a half-full freezer, about one day. Add bags of ice or dry ice to the freezer if it appears the power will be off for an extended time. You can safely refreeze thawed foods that still contain ice crystals and are 41°F or lower.

Caution: the use of dry ice may result in the unsafe build-up of carbon dioxide.

Maintain hot potentially hazardous food at 140°F or higher. Food that has reached final cooking temperature may be kept hot (140°F) by use of canned heat in chafing dishes.

When In Doubt, Throw It Out!

If it appears that power will be off for more than six hours, ice, dry ice, or frozen gel packs can be used to keep potentially hazardous foods at 41°F or lower. Moving refrigerated food to a walk-in freezer or obtaining a refrigerated truck are other options to keep food safe. Food should not be transferred to private homes. And if there’s any question about the safety of the food, throw it out!
