The humble egg is a staple in many American households, and for good reason. They’re an affordable, versatile, and nutritious food source that can be enjoyed in a variety of ways. But have you ever stopped to think about whether eggs need to be refrigerated in the US? It’s a question that may seem simple, but the answer is actually more complex than you might think.
Why Refrigeration is Important
Eggs are a type of animal byproduct, and as such, they can be contaminated with bacteria like Salmonella. Refrigeration is essential for slowing down the growth of these bacteria, which can cause serious illness in humans. In fact, the Centers for Disease Control and Prevention (CDC) estimate that there are approximately 1 million cases of foodborne illness caused by eggs each year in the US.
The Risks of Not Refrigerating Eggs
Not refrigerating eggs can lead to a number of serious health risks, including:
- Salmonella poisoning
- E. coli infections
- Other bacterial infections
These risks are particularly high for certain populations, such as the elderly, young children, and people with weakened immune systems.
The History of Egg Refrigeration
Eggs have been a part of human diets for thousands of years, and for most of that time, they were not refrigerated. In fact, it wasn’t until the late 19th century that refrigeration became a common practice in the US. Prior to that, eggs were often stored in cool, dry places like cellars or pantries, where they would be kept for several weeks or even months.
The Development of Refrigeration
The development of refrigeration was a major turning point in the history of egg production and consumption. With the invention of the icebox in the late 1800s, eggs could be stored for longer periods of time without spoiling. The introduction of electric refrigerators in the early 20th century further increased the shelf life of eggs, making it possible for people to store them in their homes for several weeks or even months.
Current Egg Refrigeration Practices
In the US, eggs are typically refrigerated at a temperature of 40°F (4°C) or below. This is because bacteria like Salmonella thrive in warm, moist environments, and refrigeration helps to slow down their growth. Eggs that are not refrigerated are more likely to be contaminated with bacteria, which can cause serious illness.
Egg Storage Tips
Here are some tips for storing eggs in the refrigerator:
| Storage Tip | Description |
|---|---|
| Store eggs in the refrigerator | Eggs should be stored in the refrigerator at a temperature of 40°F (4°C) or below. |
| Keep eggs away from strong-smelling foods | Eggs can absorb odors from other foods, so it’s best to store them away from strong-smelling foods like onions and fish. |
| Don’t wash eggs before storing them | Washing eggs can introduce bacteria into the egg, which can cause contamination. Instead, gently wipe them clean with a dry cloth before storing them. |
| Use the “first in, first out” rule | Eggs should be used in the order they were purchased, to ensure that older eggs are consumed before they spoil. |
Alternatives to Refrigeration
In some parts of the world, eggs are not refrigerated. Instead, they are stored in cool, dry places like cellars or pantries. This is often the case in countries with hot and humid climates, where refrigeration is not as common. However, this practice is not recommended in the US, where the risk of bacterial contamination is higher.
Cooking Eggs Safely
Even if eggs are refrigerated, there is still a risk of bacterial contamination. To reduce this risk, it’s important to cook eggs safely. Here are some tips:
- Use pasteurized eggs or egg products
- Cook eggs until the yolks are firm and the whites are set
- Use a food thermometer to ensure that eggs are cooked to a safe internal temperature of 160°F (71°C)
Conclusion
In conclusion, eggs do need to be refrigerated in the US. Refrigeration helps to slow down the growth of bacteria like Salmonella, which can cause serious illness. While it may seem like a simple question, the answer is actually more complex than you might think. By following proper storage and cooking techniques, you can reduce the risk of bacterial contamination and enjoy your eggs safely.
Recap
Here’s a recap of the key points:
- Eggs need to be refrigerated in the US to slow down the growth of bacteria like Salmonella
- Refrigeration helps to reduce the risk of bacterial contamination

FAQs
Q: Do eggs need to be refrigerated if they’re sold in cartons?
A: Yes, eggs sold in cartons should be refrigerated at a temperature of 40°F (4°C) or below. The carton itself does not provide a sterile environment, and refrigeration is necessary to slow down the growth of bacteria.
Q: Can eggs be stored at room temperature?
A: No, eggs should not be stored at room temperature. Eggs can absorb odors and moisture from the air, which can cause them to spoil more quickly. Refrigeration helps to keep eggs fresh for a longer period of time.
Q: Can I store eggs in the freezer?
A: Yes, eggs can be stored in the freezer, but they should be cooked before freezing. Raw eggs should not be frozen, as the risk of bacterial contamination is higher. Cooked eggs can be frozen for up to 3-4 months.
Q: Can I store eggs in the fridge door?
A: No, eggs should not be stored in the fridge door. The door is the warmest part of the refrigerator, and eggs can spoil more quickly if stored there. Instead, store eggs in the main compartment of the refrigerator at a temperature of 40°F (4°C) or below.
Q: Can I store eggs in a cooler?
A: No, eggs should not be stored in a cooler. Coolers are designed for short-term storage of food, and eggs can spoil more quickly if stored in a cooler for an extended period of time. Instead, store eggs in the refrigerator at a temperature of 40°F (4°C) or below.
