There’s an ongoing debate not only about whether eggs should be refrigerated but also whether they should be washed before storing. In some countries, keeping eggs in the refrigerator is essential to prevent the risk of Salmonella infection, while storage practices vary depending on the food safety regulations in place.
Washing eggs before placing them in the fridge might seem like a good hygiene practice, but is it actually safe?
Do Eggs Need to Be Washed Before Storage?
Some people believe washing eggs before storing them will remove dirt or bacteria from the shell. Freshly collected eggs may have dirt or feathers stuck to them, which is common with unwashed eggs straight from the farm.
While washing eggs can remove visible dirt and make them look cleaner, this practice can introduce certain risks:
- Washing eggs strips away the natural protective layer on the shell, which helps keep bacteria out.
- If eggs aren't immediately refrigerated after washing, the risk of contamination increases.
- If not properly dried, moisture can foster bacterial growth. Also, using water that's too warm may cause the eggshell's pores to open, making it easier for bacteria to enter.
In the U.S., eggs sold in stores undergo a regulated washing process that meets health standards. On the other hand, in Europe, washing eggs before sale is prohibited. European eggs retain a natural protective cuticle that shields them from bacteria.
In conclusion, washing eggs before storing them isn’t advisable. If eggs are visibly dirty or cracked, it’s better to wipe them with a dry cloth instead of washing with water. For optimal safety, use clean, uncracked eggs.
How to Properly Store Eggs in the Refrigerator
Whether to store eggs in the fridge or at room temperature is a personal choice. However, if you opt for refrigeration, here are some key guidelines:
- Store eggs in the refrigerator immediately at a temperature of 4°C (39°F) or lower.
- Keep eggs in their original carton to protect them from absorbing odors or moisture from the fridge.
- Consume eggs within three weeks to maintain the best quality.
- Do not freeze whole eggs in their shells. If freezing is necessary, beat the yolks and whites together before placing them in a labeled, freezer-safe container.
- Egg whites can be frozen separately in labeled containers.
- Frozen eggs can be stored for up to a year.
- Before storing eggs, check their freshness using the float test—place them in water. Fresh eggs will sink and lie flat, while older eggs will stand upright or float, indicating they are no longer fresh.
By following these recommendations, you can ensure that the eggs you eat remain safe and high in quality. If you have further concerns regarding egg safety, consult with a doctor. You can also use the Ai Care health consultation service by downloading it from the App Store or Play Store.
