Cracks and damage to the eggshell can provide a pathway for bacteria to enter the egg, causing spoilage.
Slime or Mold
Slime or mold on the eggshell or in the egg white or yolk can indicate bacterial contamination and spoilage.
Off Odors or Flavors
Off odors or flavors can indicate spoilage, and eggs with these characteristics should be discarded immediately.
Tips for Keeping Eggs Fresh
Here are some valuable tips for keeping eggs fresh:
Store Eggs in the Refrigerator
Store eggs in the refrigerator at a consistent temperature of 40°F (4°C) or below.
Keep Eggs Away from Strong-Smelling Foods
Eggs can absorb odors from strong-smelling foods, so it’s essential to store them away from these foods.
Don’t Wash Eggs
Avoid washing eggs, as this can remove the cuticle and make them more susceptible to bacterial contamination.
Use the “Water Test”
The “water test” can help you determine the freshness of an egg. Simply place the egg in a bowl of cold water, and if it sinks to the bottom, it’s fresh. If it stands on its end or floats, it’s likely spoiled.
