Fresh duck eggs can last unrefrigerated for up to 2 weeks, depending on factors like cleanliness, room temperature, and storage conditions. Properly storing duck eggs is crucial to maintaining their freshness and safety, especially when kept at room temperature.
Why Do Fresh Duck Eggs Last Unrefrigerated?
Duck eggs have a natural protective coating called the “bloom,” which helps keep bacteria out and moisture in. This coating helps eggs remain fresh longer without refrigeration, making it safe to keep them on the counter for a limited time. However, if the bloom is washed off, their shelf life significantly reduces.
Factors Affecting Fresh Duck Eggs’ Shelf Life Without Refrigeration
Several factors influence how long fresh duck eggs can last unrefrigerated:
-
Temperature
The ideal storage temperature is cool and consistent, ideally between 50°F to 60°F. Higher temperatures can cause faster spoilage.
-
Cleanliness
Dirty eggs or those with cracks can spoil quickly. Avoid washing the eggs unless necessary, as this removes the protective bloom.
-
Humidity
Proper humidity levels are essential. Too much moisture can lead to mold growth, while too little can cause the eggs to dry out.
-
Storage Position
Storing eggs with the pointed end down helps keep the yolk centered and maintains freshness.

How to Store Fresh Duck Eggs Unrefrigerated
- Keep Eggs Clean, But Not Washed: Avoid washing eggs unless absolutely necessary. If washing is needed, use warm water and store them in the fridge afterward.
- Use a Cool, Dry Place: Store your eggs in a cool, dry location, away from direct sunlight and heat sources. A pantry or cellar is ideal.
- Check for Cracks and Damage: Inspect eggs regularly for cracks or damage. Avoid using cracked eggs unless they are consumed immediately.
When Should You Refrigerate Fresh Duck Eggs?
While duck eggs can be kept unrefrigerated for about two weeks, refrigeration is recommended if you plan to keep them longer. Refrigerating extends their shelf life to about five weeks. Additionally, if you’ve washed the eggs, always store them in the refrigerator.
Signs That Unrefrigerated Duck Eggs Have Gone Bad
- Off Smell: Fresh eggs have little to no odor. A strong sulfuric or foul smell is a clear sign of spoilage.
- Discoloration: Check for unusual colors, such as green or black spots inside the egg, which indicate bacterial growth.
- Floating Test: Check the egg’s freshness by placing it in a bowl of water. If it floats, it’s likely spoiled and should not be consumed.
Health Implications of Consuming Spoiled Duck Eggs
Eating spoiled eggs can cause foodborne illnesses, including salmonella. To avoid health risks, always ensure your duck eggs are fresh and stored properly.
Fresh duck eggs can last up to two weeks unrefrigerated under the right conditions. For extended freshness, consider refrigerating them. Proper handling, storage, and regular checks are essential to enjoy safe, delicious duck eggs.
