When the power goes out, one of the primary concerns for many homeowners is the safety of the food stored in their refrigerators and freezers. The Centers for Disease Control and Prevention (CDC) provides guidelines on how to handle food during a power outage to prevent foodborne illnesses. In this article, we will delve into the CDC’s recommendations on the shelf life of perishable foods when the fridge is not functioning.
Understanding the Danger Zone
The CDC emphasizes the importance of understanding the “danger zone” when it comes to perishable foods. The danger zone refers to the temperature range between 40°F and 140°F, where bacteria can multiply rapidly. When the power is out, it is crucial to keep perishable foods out of this danger zone to prevent bacterial growth and food spoilage.
Refrigerator Safety
A refrigerator should maintain a temperature of 40°F or below to keep foods safe. When the power is out, the refrigerator will gradually warm up, and its ability to keep foods at a safe temperature will depend on several factors, including the initial temperature, the type of refrigerator, and how well it is insulated. The CDC recommends discarding perishable foods, such as meat, poultry, seafood, eggs, and dairy products, if they have been above 40°F for more than 2 hours.
