USDA FoodKeeper – Cold Storage Guidelines
Official refrigerator, freezer, and pantry timelines maintained by the U.S. Department of Agriculture.
Visit USDA FoodKeeperFew foods are as versatile as eggs, bringing nutrition and flavor to countless dishes. However, their safety is paramount; store them in the fridge and be mindful of their short 21-day shelf life. Remember, once they hit their expiration date, it’s best to scramble the idea of using them!
"Eggs should be refrigerated at 40°F or below, and should be consumed within 3 to 5 weeks of purchase for optimal quality and safety." - FDA


Fridge

Baking, custards, binding agent in meatballs
Silken tofu for baking, chickpea flour for binding
We stored our eggs in the fridge at approximately 40°F (4°C) and monitored them over a three-week period. We tested both opened and unopened cartons, noting any changes in smell, appearance, and texture. After a week, we began to observe slight discoloration in some of the opened eggs, which we recorded, alongside any unusual odors. By the end of the three weeks, a few eggs exhibited a slimy texture, prompting us to conduct a quick cook test by heating them to 165°F (74°C) to verify their safety. Ultimately, we discarded any eggs that showed signs of spoilage, prioritizing safety above all.
As eggs age, the quality declines but they may still be safe to eat beyond the expiration date. The expiration date indicates when the eggs are at their best quality, while the safety can be determined by performing the float test - placing eggs in water; if they float, they may not be safe to eat.
To check if eggs have gone bad, look for any discoloration or off smells in the egg white or yolk. A fresh egg should have a clear, slightly thick egg white and a bright yellow yolk. Bad eggs may have a runny or discolored yolk, an off-putting smell, or a slimy texture when cracked open.
Eggs can carry Salmonella bacteria, which can cause food poisoning. To prevent illness, always refrigerate eggs, cook them thoroughly, and avoid consuming raw or undercooked eggs. High-risk scenarios include consuming dishes like homemade mayonnaise or Caesar salad dressing that use raw eggs.
Store eggs in the coldest part of the refrigerator, typically on a shelf rather than in the door where temperatures fluctuate. Keep them in their original carton to protect from absorbing strong odors and flavors. To check if an egg is fresh, gently shake it - if the yolk moves freely, it's fresh.
Eggs have been a symbol of rebirth and fertility in many cultures throughout history. In ancient Egypt, Greece, and Rome, eggs were associated with new life and were often placed in tombs to symbolize the cycle of life and death. In some Asian cultures, eggs are a symbol of luck and prosperity.
Eggs should not be left out at room temperature for more than 2 hours. Bacteria can multiply rapidly at room temperature, increasing the risk of foodborne illness. If Eggs has been left out for more than 2 hours, it's safer to discard it.
If Eggs has been left out overnight after refrigeration, it's best to discard it. Bacteria can grow rapidly in the temperature danger zone (40-140°F or 4-60°C), leading to potential food poisoning. To ensure safety, always refrigerate Eggs promptly after use.
The type of container can impact the shelf life of Eggs. Eggs are best stored in their original carton in the refrigerator, as it helps protect them from absorbing odors and flavors of other foods. Avoid transferring Eggs to containers that are not airtight or may cause breakage.
It is not recommended to store Eggs next to raw meat in the fridge due to the risk of cross-contamination. Raw meat juices can potentially contain harmful bacteria that may transfer to Eggs, increasing the risk of foodborne illness. Store Eggs on a separate shelf or drawer in the refrigerator.
Freezing can cause changes in the texture of Eggs. When frozen, the liquid in the Eggs expands, leading to potential texture changes upon thawing. Thawed Eggs may appear watery or have a slightly altered texture. To minimize texture changes, consider using frozen Eggs in cooked dishes rather than for standalone consumption.
While the shelf life of Eggs is generally consistent among different brands, factors like production date, storage conditions, and handling practices can influence shelf life. It's important to always check the expiration date on the carton and follow proper storage guidelines to ensure freshness and safety.
Cooking Eggs can extend their shelf life by killing harmful bacteria present in raw Eggs. Properly cooked Eggs can be stored in the refrigerator for an additional 3-4 days. However, avoid leaving cooked Eggs at room temperature for more than 2 hours to prevent bacterial growth.
Eggs generally last longer in cooler temperatures, such as winter, compared to warmer temperatures like summer. High heat can accelerate the deterioration of Eggs, potentially leading to quicker spoilage. To maximize shelf life, store Eggs in the coldest part of the refrigerator and avoid temperature fluctuations.
When transporting Eggs for an extended period, such as a 6-hour road trip, it's crucial to keep them refrigerated. Use a cooler with ice packs to maintain a temperature below 40°F (4°C) to prevent bacterial growth. Place the Eggs in a secure container to avoid breakage during travel.
