Question

Why are eggs sometimes kept in the refrigerated section of grocery stores, while other times they're not?

Answer 1

The storage of eggs in the refrigerated or non-refrigerated section of grocery stores can vary based on the country or region's food safety regulations and industry practices. The main factors that influence where eggs are stored include:

1. Washing process: In some countries, eggs are washed before they are sold in grocery stores. Washing removes dirt, bacteria, and other contaminants from the eggshell, but it also removes the egg's natural protective cuticle. Without the cuticle, the eggs become more susceptible to bacteria entering through the porous shell. To counter this, washed eggs need to be refrigerated to inhibit bacterial growth and maintain their freshness.

2. Farm practices: In regions where eggs are not washed before sale, the protective cuticle remains intact, providing a natural barrier against bacteria. In these cases, eggs can be safely stored at room temperature, and they are often found in the non-refrigerated sections of grocery stores.

3. Regulation and recommendations: Food safety regulations and guidelines from health authorities play a significant role in determining whether eggs should be refrigerated or not. Different countries or regions may have varying rules on egg handling and storage, leading to different practices in grocery stores.

For example:

• In the United States, eggs are washed before being sold, and it is recommended to store them in the refrigerator to prevent contamination and ensure safety.
• In many European countries, eggs are often not washed, and it is common for them to be sold at room temperature.

Regardless of whether eggs are stored in the refrigerated or non-refrigerated section, it's important for consumers to follow the storage instructions on the carton. If the eggs are sold in the refrigerated section, they should be kept in the refrigerator at home. If they are sold at room temperature, it is generally safe to store them at room temperature until their expiration date. However, if you're uncertain about the storage requirements, it's best to err on the side of caution and refrigerate the eggs.
