Food Safety During Prolonged Power Outage

Montgomery County Health Officer Dr. Ulder J. Tillman today urged residents who remain without power to take steps to ensure that food left in the refrigerator and freezer is safe.

According to the United States Department of Agriculture’s (USDA) Food Safety and Inspection Service, meat, poultry, fish and eggs should be refrigerated at 40° F and frozen food at or below 0° F, which may be difficult with a prolonged power outage.

• Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature. A refrigerator will only keep food safely cold for about four hours if it is unopened.
• A full freezer will hold the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed.
• Obtain dry ice or block ice to keep your refrigerator as cold as possible if there is a prolonged power outage. Residents should check with local retailers for ice supplies.
• Digital, dial or instant-read thermometers and appliance thermometers will help determine if the food is at safe temperatures. The refrigerator temperature should be at 40°F or below; the freezer, 0°or lower.
• To be sure a particular food is cold enough; take its temperature with a food thermometer.
• Never taste food to determine its safety!
• Food may be safely refrozen if the food still contains ice crystal or is at 40°F or below. Evaluate each food item separately. Be sure to discard any items in either the freezer or the refrigerator that have come into contact with raw meat juices.
• Food such as meat, poultry, fish, eggs, milk, soft cheeses, butter and leftover cooked meats, casseroles and pizza should be thrown out if they have been held above 40° F for over two hours.
