Do eggs need to be refrigerated and Washed?

do eggs need to be refrigerated

The question of whether Do eggs need to be refrigerated and washed has been a topic of debate among consumers. To shed some light on the matter, we sought the advice of Toby Amidor, an esteemed nutrition expert and bestselling author. Here’s what Amidor had to say about it.

In the United States, refrigeration is indeed recommended for eggs. According to Amidor, eggs should be refrigerated immediately after being laid by hens. The reason behind this is twofold. Firstly, there is a concern regarding the growth of Salmonella bacteria, which tends to thrive at room temperature. Refrigeration helps to inhibit its multiplication and ensure food safety.

Secondly, USDA-graded eggs undergo a washing and sanitization process as per FDA regulations. While this process removes the eggs’ outer coating, it also exposes the shell’s pores, making the egg more vulnerable to potential contamination. Refrigerating the eggs helps to preserve their freshness and reduce the risk of bacterial growth.

As for washing eggs, it is generally recommended to refrain from doing so. The protective outer coating on the eggs, known as the bloom or cuticle, acts as a natural barrier against bacteria. Washing the eggs removes this protective layer and can potentially introduce bacteria through the shell’s pores. Therefore, it is advisable to leave the eggs unwashed unless absolutely necessary, such as when they are visibly soiled.

If you live in the United States, it is recommended to refrigerate eggs promptly after purchase to ensure food safety and prevent bacterial growth. Additionally, it is best to avoid washing eggs unless they are visibly dirty. By following these practices, you can enjoy fresh and safe eggs in your culinary endeavors.

Why Do Some Countries Not Refrigerate Eggs?

The practice of not refrigerating eggs in certain countries has sparked curiosity among many. To shed light on this matter, we turned to Toby Amidor, a renowned nutrition expert. Here’s what Amidor shared about the reasons behind this difference.

In some countries, eggs are not washed after harvesting, leaving the natural thin layer known as the cuticle intact. This thin layer serves as a protective barrier for the eggshell, minimizing the chances of bacteria entering the shell’s pores and preventing the infiltration of Salmonella into the egg itself. By preserving the natural cuticle, these countries rely on its inherent properties to safeguard the eggs.

Furthermore, the varying distances eggs need to travel from farm to market or point of sale can influence refrigeration practices. In countries where the distance is relatively shorter, there may be less urgency to refrigerate the eggs. This is because the eggs reach consumers more quickly, reducing the potential for bacterial growth and maintaining their freshness without the need for refrigeration.

It is important to note that different countries may have specific regulations and practices regarding egg handling and storage based on their food safety standards and local conditions. These variations contribute to the diverse approaches observed around the world.

In summary, in some countries, eggs are not refrigerated due to the intact cuticle that acts as a natural protective layer. Additionally, factors such as shorter distances from farm to market influence the need for refrigeration. Each country’s unique regulations and circumstances play a role in determining the most appropriate handling and storage practices for eggs. 

Should Fresh Eggs Be Refrigerated?

When it comes to freshly laid eggs, refrigeration is essential. If you’ve recently purchased eggs from a farmers market or any other source, it’s important to refrigerate them as soon as you get home. The United States Department of Agriculture (USDA) guidelines recommend storing eggs at or below 40 degrees Fahrenheit to minimize the risk of Salmonella contamination.

To ensure optimal safety and freshness, it’s advisable to store eggs in their original carton. The carton provides some protection against potential temperature fluctuations and helps prevent any potential odors from affecting the eggs. Additionally, it’s recommended to place the eggs in the coldest part of the refrigerator, typically on one of the main shelves, rather than in the refrigerator door. The door tends to experience more temperature fluctuations, which can impact the quality and safety of the eggs.

By promptly refrigerating fresh eggs and following these guidelines, you can help maintain their quality and minimize the risk of foodborne illnesses.

What is the Time Limit for Eggs at Room Temperature?

According to guidelines from the USDA, refrigerated eggs should not be left out at room temperature for more than two hours. Toby Amidor explains that eggs are immediately stored in a cold environment after being laid by hens. When a cold egg is left out and exposed to room temperature, it can develop condensation, creating a favorable environment for bacteria to enter the egg and potentially promote bacterial growth.

Is Washing Eggs Necessary?

No, washing eggs is not necessary. Toby Amidor clarifies that eggs are already washed and sanitized according to strict government guidelines that adhere to FDA regulations. The existing washing process ensures that the eggs are safe and clean for consumption. Therefore, there is no need for consumers to wash eggs again before using them in their culinary endeavors.

Helpful Tips for Purchasing and Storing Eggs

When it comes to shopping for eggs and ensuring their optimal storage, the USDA provides valuable guidelines to keep in mind. Here are some useful tips:

Choose Grade A or AA eggs: Opt for eggs that are classified as Grade A or AA. Grade AA eggs have thick and firm whites, high and round yolks with minimal defects, and clean, unbroken shells. Grade A eggs possess similar qualities to Grade AA, with reasonably firm whites. These are the most commonly available quality grades in stores.

Check for clean and intact shells: Inspect the eggs before purchasing to ensure that the shells are clean and free from any cracks. Avoid buying eggs with cracks, as they can provide a pathway for bacteria to enter.

Confirm refrigeration at the store: Ensure that the eggs have been properly refrigerated while at the store. It’s crucial to prevent bacterial growth, which can occur rapidly when eggs are stored at room temperature.

Refrigerate eggs promptly at home: Once you bring the eggs home, refrigerate them promptly. Keep them in their original carton and place them in the coldest section of your refrigerator, typically on the main shelves. Avoid storing eggs in the refrigerator door, as it experiences temperature fluctuations. Maintain a temperature of 40 degrees Fahrenheit or below for optimal storage.

Handle cracked eggs separately: If you happen to notice a cracked egg during transportation, break it into a clean container, cover it tightly, and store it in the refrigerator. Consume the cracked egg within two days to ensure its freshness and safety.

By following these tips, you can make informed choices while purchasing eggs and ensure proper storage, maximizing their quality and safety for your consumption.

How much protein in one egg?

In general, one large egg contains approximately 6 grams of protein. Keep in mind that the protein content may vary slightly depending on the size of the egg.
