Eggs are a staple in many kitchens, prized for their versatility, nutritional value, and affordability. However, accidents happen, and sometimes you might find yourself with cracked eggs. Knowing what to do with them, especially how long they remain safe to consume when refrigerated, is crucial to prevent foodborne illness. This guide will delve into the factors that influence the shelf life of cracked eggs, proper storage techniques, and how to identify signs of spoilage.
Understanding the Risks of Cracked Eggs
A cracked egg is more than just a cosmetic issue; it compromises the egg’s natural defenses against bacteria. The eggshell is porous, but a protective cuticle layer helps prevent microorganisms from entering. Once cracked, this barrier is breached, making the egg vulnerable to contamination.
Why Cracks Matter: Bacteria and Beyond
Salmonella is the most common concern associated with eggs. While salmonella can be present inside an egg, it’s more frequently found on the shell. Cracks provide an easy entry point for these bacteria to contaminate the egg’s contents. Besides salmonella, other bacteria and molds can also infiltrate a cracked egg.
Cracked eggs are also susceptible to losing moisture, leading to a change in texture and flavor. The egg white might become watery, and the yolk can dry out. These changes, while not necessarily harmful, can affect the quality of your cooking or baking.
How Long Cracked Eggs Last in the Fridge
The general consensus is that cracked eggs, when properly handled and stored, are safe to consume within 2 days of cracking. However, several factors can influence this timeframe.
Factors Affecting Shelf Life
The freshness of the egg before it was cracked plays a significant role. A freshly laid egg will generally last longer than an older egg, even when cracked. The storage temperature is also crucial; maintaining a consistently cold refrigerator temperature (below 40°F or 4°C) is vital for inhibiting bacterial growth.
The cleanliness of the cracked egg is another key factor. If the egg came into contact with a contaminated surface during or after cracking, it’s more likely to spoil quickly. Cross-contamination from other foods in your refrigerator can also shorten its shelf life.
Safe Handling Practices
Prompt refrigeration is essential. Do not leave cracked eggs at room temperature for more than two hours. Bacteria multiply rapidly at room temperature. If you crack an egg and don’t plan to use it immediately, transfer the contents to a clean, airtight container. Label the container with the date you cracked the egg to ensure you use it within the recommended timeframe.
Proper Storage Techniques for Cracked Eggs
Storing cracked eggs correctly can significantly impact their shelf life and safety. Proper storage involves selecting the right container, maintaining the correct temperature, and avoiding cross-contamination.
Container Selection and Preparation
Use a clean, airtight container, preferably made of glass or plastic, to store cracked eggs. This prevents the egg from absorbing odors from other foods in the refrigerator and protects it from further contamination. Before placing the eggs in the container, ensure it is thoroughly washed and dried. Avoid using containers that have previously held raw meat or poultry without a thorough cleaning.
Maintaining Consistent Refrigeration
Ensure your refrigerator is consistently maintained at a temperature below 40°F (4°C). Use a refrigerator thermometer to monitor the temperature regularly. Avoid placing the container of cracked eggs in the refrigerator door, as the temperature in the door fluctuates more than in other parts of the refrigerator.
Preventing Cross-Contamination
Store the container of cracked eggs on a shelf away from raw meat, poultry, and seafood to prevent cross-contamination. If possible, store the container on a higher shelf to prevent drips from contaminating other foods. Always wash your hands thoroughly with soap and water before and after handling eggs.
Identifying Spoiled Cracked Eggs
Even when stored correctly, cracked eggs can still spoil. Knowing how to identify signs of spoilage is crucial for preventing foodborne illness. There are several indicators to look for, including changes in appearance, smell, and texture.
Visual Inspection
Examine the egg white and yolk for any discoloration. A greenish or pinkish tint indicates bacterial contamination. Check for the presence of mold or any unusual spots. The egg white should be clear and slightly viscous, not overly watery. The yolk should be round and firm, not flat or broken.
The Sniff Test
The most reliable way to determine if an egg is spoiled is to smell it. A spoiled egg will have a distinct, unpleasant odor, even when raw. This smell is caused by the production of hydrogen sulfide and other gases by bacteria. If the egg smells even slightly off, discard it immediately.
Texture Assessment
A fresh egg white will be slightly thick and gelatinous. If the egg white is very watery or slimy, it’s likely spoiled. Similarly, the yolk should be firm and easily separate from the white. If the yolk is runny or breaks easily, it’s a sign that the egg is no longer fresh.
Using Cracked Eggs Safely
If you have cracked eggs that you need to use up within the recommended timeframe, there are several ways to incorporate them into your cooking and baking. Just be sure to cook them thoroughly to kill any potential bacteria.
Cooking Thoroughly
When using cracked eggs, ensure they are cooked thoroughly. This means cooking them until the egg white is completely set and the yolk begins to thicken. Avoid consuming raw or lightly cooked eggs, such as in homemade mayonnaise or hollandaise sauce, as these preparations do not reach temperatures high enough to kill bacteria. Scrambled eggs, omelets, and baked goods are good options for using cracked eggs safely.
Baking with Cracked Eggs
Cracked eggs can be used in baking recipes as long as they are fresh and show no signs of spoilage. Baking temperatures typically reach high enough to kill any bacteria that may be present in the eggs. Cakes, cookies, and muffins are all excellent choices for using cracked eggs.
Alternatives to Using Cracked Eggs Immediately
If you have more cracked eggs than you can use within two days, consider freezing them. Freezing can extend their shelf life and allow you to use them later.
Freezing Cracked Eggs
Crack the eggs into a clean bowl and whisk them thoroughly. You can freeze whole eggs, egg whites, or egg yolks separately. Pour the whisked eggs into freezer-safe containers, leaving some headspace for expansion. Label the containers with the date and the number of eggs. Frozen eggs can be stored for up to a year. To use frozen eggs, thaw them in the refrigerator overnight or under cold running water. Use thawed eggs immediately and do not refreeze them.
Freezing egg whites is straightforward. Simply pour them into a freezer-safe container and label them. Egg yolks, however, can become thick and gelatinous when frozen. To prevent this, add a pinch of salt or sugar per four egg yolks before freezing. This helps to maintain their texture.
Understanding Egg Grades and Quality
The quality and grade of eggs can also influence their safety and shelf life. Knowing how to interpret egg grades can help you make informed decisions about egg purchases and storage.
Egg Grading System
In the United States, the USDA grades eggs based on their quality. The grades are AA, A, and B, with AA being the highest quality. Grade AA eggs have thick, firm whites and yolks that are high and round. Grade A eggs are similar but may have slightly thinner whites. Grade B eggs have thinner whites and flatter yolks.
The grade of an egg is determined by several factors, including the appearance of the shell, the firmness of the white and yolk, and the size of the air cell inside the egg. Higher-grade eggs are generally fresher and have a longer shelf life than lower-grade eggs.
Quality Considerations
While egg grading provides an indication of quality, it’s important to consider other factors as well. Look for eggs that have clean, uncracked shells. Check the expiration date on the carton and choose eggs that are as fresh as possible. Support local farmers and producers who prioritize humane animal treatment and sustainable farming practices.
Debunking Common Myths About Egg Storage
There are several common misconceptions about egg storage that can lead to confusion and potentially unsafe practices. It’s important to dispel these myths and rely on evidence-based recommendations.
Myth: Eggs Should Be Stored in the Refrigerator Door
Fact: The refrigerator door is one of the warmest parts of the refrigerator and experiences frequent temperature fluctuations. Storing eggs in the door can shorten their shelf life and increase the risk of spoilage. Eggs should be stored in the main body of the refrigerator, where the temperature is more consistent.
Myth: Washing Eggs Improves Their Shelf Life
Fact: Washing eggs can actually remove the protective cuticle layer on the shell, making them more susceptible to bacterial contamination. Commercially sold eggs in the United States are already washed and sanitized, so washing them again is unnecessary and potentially harmful.
Myth: Floating Eggs Are Always Spoiled
Fact: The float test can provide an indication of an egg’s freshness, but it’s not a foolproof method for determining spoilage. As an egg ages, air enters through the porous shell, causing it to float. However, an egg can float even if it’s still safe to eat, especially if it’s been stored for a long time. Always rely on the sniff test and visual inspection to determine if an egg is spoiled.
Summary of Safe Practices
In conclusion, cracked eggs are safe to use within 2 days if stored properly in the refrigerator. Prioritize prompt refrigeration in a clean, airtight container, maintaining a temperature below 40°F (4°C). Always cook cracked eggs thoroughly. Discard any eggs that show signs of spoilage, such as discoloration, unpleasant odor, or watery texture. By following these guidelines, you can minimize the risk of foodborne illness and enjoy eggs safely.

How long can I safely keep cracked eggs in the refrigerator?
Cracked eggs, whether store-bought or fresh from your backyard hens, should be used immediately or cooked thoroughly as soon as possible. The shell is a natural barrier against bacteria, and once it’s compromised, bacteria such as Salmonella can easily contaminate the egg. Keeping cracked eggs in the fridge, even for a short period, significantly increases the risk of foodborne illness.
Generally, the recommendation is to discard cracked eggs unless you plan to use them right away. If you’ve cracked an egg accidentally while cooking, use it in that dish. Do not store leftover cracked eggs in the refrigerator with the intention of using them later. Prioritizing safety and avoiding any potential contamination is always the best approach when dealing with cracked eggs.
What if the crack in the eggshell is very small? Is it still unsafe?
Even a small crack in the eggshell can compromise the protective barrier, allowing bacteria to enter. While a larger crack obviously poses a greater risk, even hairline fractures can create pathways for contamination. The eggshell is porous, and any breach in its integrity allows microorganisms to penetrate and multiply. Therefore, any cracked egg, regardless of the crack’s size, should be treated with caution.
It’s always best practice to err on the side of caution when dealing with cracked eggs. Using the egg immediately after cracking is the only safe option. Avoid storing even slightly cracked eggs in the refrigerator, as the risk of bacterial growth increases over time. Discarding the egg if immediate use isn’t possible is the safest course of action.
Can I freeze cracked eggs to extend their shelf life?
Freezing cracked eggs is not recommended for safety reasons. First, the crack in the shell exposes the egg to potential bacterial contamination before freezing. Secondly, the freezing process can further damage the shell and allow moisture and bacteria to enter. Even if frozen promptly, the risk associated with bacterial growth before and during the freezing process remains significant.
Furthermore, the texture of the egg white can change upon thawing, making it watery and less appealing for certain culinary applications. If you want to freeze eggs, crack them into a clean container, whisk them together (or separate yolks and whites depending on your needs), and then freeze them in airtight containers or freezer bags. Always label the containers with the date and the number of eggs. This process should only be done with eggs that have not been cracked prior to intentional preparation for freezing.
How can I tell if a cracked egg has gone bad?
Visually inspecting a cracked egg for signs of spoilage can be difficult, but there are a few indicators to look for. A discolored yolk or white, a slimy or watery texture, or any presence of mold should be considered a sign that the egg is unsafe to consume. Also, if the egg smells sulfuric or rotten, it is definitely spoiled and should be discarded immediately. Remember that even without visible signs, bacteria can still be present and cause illness.
However, relying solely on visual or olfactory cues is not always reliable in detecting contamination. Salmonella, for instance, doesn’t always produce obvious signs of spoilage. Because of this, the primary indication of a cracked egg’s unsuitability for consumption is simply the presence of the crack itself. Any egg with a cracked shell should be used immediately or discarded, regardless of its apparent condition.
What are the risks of eating a cracked egg that’s been in the fridge?
The primary risk associated with consuming a cracked egg that has been refrigerated is Salmonella infection. Salmonella bacteria can penetrate the cracked shell and multiply rapidly, even at refrigeration temperatures. Consuming eggs contaminated with Salmonella can lead to food poisoning, characterized by symptoms such as diarrhea, fever, abdominal cramps, and vomiting, typically starting within 12 to 72 hours after infection.
Besides Salmonella, other bacteria can also enter through the crack and cause foodborne illness. The severity of the illness can vary depending on the type and amount of bacteria present, as well as the individual’s health status. Children, pregnant women, the elderly, and individuals with weakened immune systems are at a higher risk of experiencing more severe symptoms from foodborne illnesses. Therefore, it’s crucial to prioritize food safety and avoid consuming cracked eggs that have been stored in the refrigerator.
If I accidentally crack an egg while bringing it home from the store, what should I do?
If you discover a cracked egg after returning from the store, it’s important to handle it carefully. If you plan to use the egg immediately, crack it into a clean bowl and cook it thoroughly. This includes ensuring that both the yolk and white are firm. Cooking the egg to an internal temperature of 160°F (71°C) will kill any harmful bacteria that may be present.
However, if you don’t intend to use the egg immediately, it’s best to discard it. Attempting to store a cracked egg in the refrigerator, even for a short period, poses a significant risk of bacterial contamination. Choosing to discard the egg eliminates any potential health risks associated with consuming a potentially contaminated product. Prioritizing food safety is always the best approach in this situation.
Does washing cracked eggs make them safer to store in the fridge?
Washing cracked eggs is not recommended and will not make them safer to store in the refrigerator. Washing can actually drive bacteria further into the egg through the crack, increasing the risk of contamination. The eggshell has a natural protective coating called the bloom or cuticle, which helps prevent bacteria from entering. Washing removes this coating, making the egg more susceptible to bacterial invasion.
Furthermore, water can create a moist environment within the crack, which can encourage bacterial growth. The best practice for dealing with cracked eggs is to use them immediately or discard them. Washing a cracked egg will not eliminate the risk of bacterial contamination, and attempting to store it in the refrigerator after washing is still unsafe.
