Eggs are a staple food in many households, and it’s not uncommon to find them in most refrigerators. However, sometimes you might notice that your eggs have developed an unwelcome guest – mold. This can be a concerning and unpleasant discovery, especially if you’re not sure what causes it or how to prevent it. In this article, we’ll delve into the reasons why your eggs might have mold and provide you with some valuable tips on how to keep your eggs fresh and mold-free.
Understanding Egg Mold
Before we dive into the reasons why your eggs might have mold, it’s essential to understand what egg mold is and how it forms. Egg mold is a type of fungus that grows on the surface of eggs, typically in the form of green, black, or white patches. It’s usually caused by the presence of moisture, bacteria, or other microorganisms on the eggshell.
Egg mold can form in various ways, including:
-
Contamination during handling
Eggs can become contaminated with bacteria or other microorganisms during handling, especially if they’re not stored properly. When eggs are washed or cleaned, the pores on the eggshell can become open, allowing bacteria to enter the egg. If the eggs are not dried properly, the moisture can create an ideal environment for mold to grow.
-
High humidity
Eggs can absorb moisture from the air, especially in humid environments. When the air is too humid, the eggs can become damp, creating an ideal environment for mold to grow.
-
Temperature fluctuations
Eggs should be stored in a consistent refrigerator temperature below 40°F (4°C). If the temperature fluctuates, the eggs can become more susceptible to mold growth.
-
Poor storage conditions
Eggs should be stored in a clean, dry place, away from direct sunlight and heat sources. If the eggs are stored in a dirty or damp environment, they can become contaminated with bacteria or other microorganisms, leading to mold growth.
Why Do Your Eggs Have Mold?

What causes mold to grow on eggs in the fridge?
Mold growth on eggs in the fridge is often caused by the presence of moisture and bacteria. When eggs are not stored properly, moisture can seep into the eggshell, creating an ideal environment for mold to grow. Additionally, if the eggs are not cleaned and dried before being stored in the fridge, any bacteria present on the surface of the egg can multiply and cause mold to form.
It’s also worth noting that some types of mold can penetrate the eggshell and grow inside the egg. This can happen if the egg is not stored at a consistent refrigerator temperature below 40°F (4°C). If the temperature fluctuates, it can cause the egg to sweat, creating a moist environment that fosters mold growth.
How can I prevent mold from growing on my eggs in the fridge?
To prevent mold from growing on your eggs in the fridge, it’s essential to store them properly. Make sure to clean and dry the eggs before storing them in the fridge. You can use a clean cloth or paper towel to gently wipe down the eggs and remove any dirt or debris. Then, place the eggs in a covered container or carton to prevent moisture from entering.
It’s also crucial to maintain a consistent refrigerator temperature below 40°F (4°C). Check your fridge’s temperature regularly to ensure it’s within the safe range. Additionally, make sure to use the eggs within a few weeks of purchase, as older eggs are more susceptible to mold growth.
What are the signs of mold growth on eggs?
The signs of mold growth on eggs can vary depending on the type of mold and the stage of growth. However, some common signs include visible mold or mildew on the surface of the egg, a slimy or soft texture, and an off or sour smell. In some cases, the egg may also have a pinkish or greenish tint.
If you notice any of these signs, it’s essential to discard the egg immediately. Mold can produce toxins that can cause food poisoning, so it’s better to err on the side of caution.
