Food safety experts explained the duration of food safety in refrigerators and freezers after a power outage. When the power goes out, many people wonder whether the food is still safe to consume or should be discarded. According to the information provided, a refrigerator can keep food cold for up to four hours if the door remains closed.
Duration of Food Safety
Dr. Vance Kauffman, president of the "Stop Foodborne Illness" coalition, stated that a full freezer can maintain its temperature for about 48 hours, while a half-full freezer's time reduces to 24 hours. This time is only valid if the freezer door remains closed. Therefore, preventing the opening of the refrigerator and freezer doors is key to preserving food.

Tips for Identifying Safe Food
Experts in the field warn that relying on your senses to determine food safety can be dangerous. For example, bad smells or unusual appearances may not be reliable indicators of food safety. Dr. Melissa Vaccaro, a food safety program specialist at the National Environmental Health Association, emphasized that food should never be judged by its appearance or smell. The best method for determining safety is to pay attention to time.
If the refrigerator temperature reaches room temperature, food will spoil. Perishable foods such as milk, cheese, meat, and leftovers should not remain at room temperature for more than two hours. If this time has elapsed, they should be discarded.

Experts also suggested using refrigerator and freezer thermometers to preserve food during a power outage. These thermometers can help you know whether the food is still at a safe temperature. Additionally, using ice and gel packs in portable refrigerators can help maintain temperature.
By following these tips, food can be more effectively protected during a power outage, preventing waste.
