To check if an egg is bad, perform the water test—gently place the egg in a bowl of water. Fresh eggs will sink and lie flat on the bottom, while older eggs will stand upright or float, indicating spoilage. Sniff the egg when cracked open; a sour or sulfur-like smell suggests it's gone bad. Visual inspection is also key—discolored yolk or whites are signs of spoilage. Avoid consuming any egg if there's doubt about its freshness to ensure safety. Always store eggs in a refrigerator to extend their shelf life.

FAQs & Answers

  1. What is the best way to determine if an egg is still fresh? The best way to determine if an egg is fresh is by performing the water test. Place the egg in a bowl of water; if it sinks and lies flat on the bottom, it is still fresh. If it stands upright or floats, it is no longer good to eat.
  2. What does it mean if an egg floats in water? If an egg floats in water, it indicates that it is older and likely spoiled. This happens because air enters the egg as it ages, increasing its buoyancy.
  3. How can I tell if a cracked egg is bad? To check if a cracked egg is bad, sniff it after cracking open; a sour or sulfur-like smell is a clear sign of spoilage. Additionally, inspect the yolk and whites for any discoloration.
  4. How should I store eggs to ensure freshness? Eggs should be stored in the refrigerator to extend their shelf life. Keeping them at a consistent, cool temperature helps maintain their freshness and safety.
