How Long Do Fresh, Unwashed Eggs Last in the Refrigerator?

Refrigerators Hub

Eggs are a versatile and nutritious staple in many kitchens around the world. Whether you use them for baking, frying, scrambling, or as a key ingredient in countless recipes, eggs are a valuable addition to your diet.

However, like all food items, eggs have a limited shelf life, and understanding how long fresh, unwashed eggs last in the refrigerator is crucial for ensuring their safety and quality.

The Shelf Life of Unwashed Eggs

The shelf life of eggs can vary depending on how they are stored and handled. One key factor to consider is whether the eggs have been washed or not. In the United States, commercial egg producers are required to wash and sanitize eggs before they are sold to consumers. This washing process removes the outer protective layer of the eggshell, known as the cuticle or bloom, which can make the eggs more vulnerable to bacterial contamination. In many other countries, however, eggs are not washed and still have this protective coating intact. Here, we will focus on the shelf life of unwashed eggs, as this information is applicable to a broader global audience.

Storing Unwashed Eggs for Extended Freshness

Fresh eggs, whether washed or unwashed, have a protective layer that helps seal the shell and prevent bacteria from entering. However, this natural bloom diminishes over time, which is why eggs have an expiration date.

Guidelines for Storing Unwashed Eggs

If you have unwashed, farm-fresh eggs, you can store them in the refrigerator to extend their shelf life. Here’s a general guideline on how long unwashed eggs can last in the refrigerator:

Room Temperature vs. Refrigeration:

Eggs should ideally be stored in the refrigerator. This significantly prolongs their freshness. The temperature in the refrigerator should be around 40°F (4.4°C) or lower.

Egg Age Matters:

The freshness of unwashed eggs can vary depending on how old they were when you acquired them. If you collect eggs from your backyard chickens or purchase them from a local farm, the eggs are typically fresher than those found in supermarkets. Fresh unwashed eggs can last for several weeks in the refrigerator, often up to 2 to 3 months.

Perform the Float Test:

To check the freshness of unwashed eggs, you can perform the float test. Fill a bowl with water and gently place the eggs in it. Fresh eggs will sink and lay flat at the bottom, while older eggs will stand upright or float. It’s best to consume eggs that sink, as they are the freshest.

Regularly Rotate Eggs:

To ensure even aging, occasionally rotate the eggs in your refrigerator. This helps distribute any temperature variations and keeps your eggs fresher for a longer period.

Pay Attention to Odor and Appearance:

Always inspect the eggs for any signs of spoilage, such as an off smell or unusual discoloration. If the egg smells bad or looks abnormal, discard it.

Use-By Dates:

If you have purchased unwashed eggs from a local source or farm, there may not be a “use-by” or expiration date on them. In such cases, it’s a good practice to label the eggs with the date of acquisition to keep track of their freshness.

Maintaining Quality and Flavor

It’s important to note that as eggs age, their quality and flavor may decline. While they may still be safe to eat, fresher eggs generally taste better and produce fluffier baked goods.

Unwashed eggs from your backyard or a local farm can last for an extended period in the refrigerator, often up to 2 to 3 months. The key is to store them properly, maintain a consistent refrigerator temperature, and regularly check for freshness. The float test is a handy method to assess the freshness of your eggs. By following these guidelines, you can enjoy delicious, farm-fresh eggs for an extended period while ensuring the safety of your meals.
