Many people store eggs in the fridge door for easy access, but this is not the best option. Experts emphasize that the fridge door is the warmest area, prone to temperature fluctuations. Storing eggs here increases the risk of bacterial growth, which can lead to spoilage.
The Coldest Spot in the Fridge Is Best
Jeanine Flaherty of Vital Farms recommends keeping eggs in the coldest part of your refrigerator. Shelves at the back of the fridge are ideal because they maintain a consistently cold environment. This helps keep eggs fresh for up to five weeks, preventing bacteria from thriving.
How Temperature Fluctuations Affect Eggs
Eggs should be stored at around 40°F (4°C) for optimal safety when temperatures fluctuate, especially above 45°F (7°C), condensation forms on the eggshell, encouraging bacterial growth. A refrigerator thermometer is a useful tool to ensure the temperature stays consistent.
Eggs Have Natural Protection, But It’s Not Foolproof
Eggshells have porous surfaces, but they also contain protective membranes that help block bacteria. However, if an eggshell is cracked or damaged, bacteria can enter the egg, increasing the risk of contamination. Keeping eggs at a stable, cold temperature minimizes this risk.
Egg Cartons Are Essential for Safety
While egg crates and bowls may look appealing, experts advise keeping eggs in their original carton. Cartons protect eggs from absorbing unwanted odors in the fridge and provide a buffer from temperature fluctuations, which helps maintain freshness and safety.
Protecting Eggs from Odors and Humidity
Cartons not only shield eggs from temperature changes but also prevent the absorption of strong odors from other foods. They also maintain consistent humidity around the eggs, which is critical for preserving their quality and keeping them fresh for a longer time.
Why Some Countries Don’t Refrigerate Eggs
In some parts of the world, eggs aren’t refrigerated because of how they’re processed. For example, in the U.S., eggs are washed, removing a natural protective coating called the “cuticle,” which makes refrigeration necessary to prevent bacteria from entering. In other countries, eggs are often left unwashed, keeping the cuticle intact.
What Happens If Eggs Are Stored Incorrectly
If eggs are kept in a place where temperatures frequently change, condensation may form on the shell, leading to bacteria growth. If eggs look or smell off, or if they’ve been left out for too long, it’s best to discard them rather than risk illness.
How Long Do Eggs Stay Fresh?
When stored properly in a cold and stable environment, eggs can last three to five weeks from their pack date. Always check the “best by” date on the carton and trust your senses—if something smells off, it’s better to be cautious.
Ensure Your Eggs Are Always Safe
By keeping eggs in their original carton and storing them in the coldest part of the fridge, you can extend their freshness and reduce the risk of contamination. How do you currently store your eggs, and could these tips help improve their shelf life?
