How to tell if eggs are still good

By Posted on

Determining if eggs are still good is essential for food safety and ensuring that you're consuming fresh, quality eggs. As eggs age, their quality declines, and they may spoil, posing a risk of foodborne illness if consumed. Fortunately, there are several methods for checking the freshness of eggs, including visual inspection, the water test, the float test, and the smell test. In this guide, we'll explore each method in detail, along with tips for storing eggs properly to maintain their freshness.

Visual Inspection

  1. Check the Date: Start by checking the expiration or "best by" date printed on the egg carton. This date indicates the recommended date by which the eggs should be consumed for the best quality. However, it's essential to note that eggs can still be safe to eat beyond this date if stored properly.

  2. Inspect the Shell: Examine the eggshell for any signs of damage or cracks. Fresh eggs should have clean, unblemished shells. Cracks or leaks in the shell can allow bacteria to enter the egg and spoil its contents.

  3. Look for Discoloration: Fresh eggs typically have a clean, uniform color. Avoid eggs with any discoloration or unusual spots on the shell, as this may indicate spoilage or bacterial growth.

  4. Check the Egg White and Yolk: Crack the egg open onto a clean plate or into a bowl and examine the egg white and yolk. Fresh egg whites should be clear and slightly viscous, while fresh yolks should be round and domed. Avoid eggs with cloudy or runny whites, as well as yolks that appear flattened or discolored.

Water Test

  1. Fill a Bowl with Water: Fill a bowl or container with enough water to fully submerge the eggs.

  2. Submerge the Eggs: Gently place the eggs into the water one at a time. Fresh eggs will sink and lie flat on the bottom of the bowl.

  3. Observe the Results: Observe the position of the eggs in the water. Fresh eggs that lie flat on the bottom are safe to consume. Eggs that stand upright on one end or float to the surface may be less fresh and should be discarded.

Float Test

  1. Fill a Glass with Water: Fill a tall glass or cup with water.

  2. Submerge the Egg: Gently place the egg into the water. Fresh eggs will sink and lie flat on the bottom of the glass.

  3. Observe the Results: Observe the position of the egg in the water. If the egg stands upright on one end or floats to the surface, it may be less fresh and should be discarded.

Smell Test

  1. Sniff the Egg: Hold the egg close to your nose and sniff it carefully. Fresh eggs typically have a neutral odor or a faint, slightly eggy smell.

  2. Detect Any Off Odors: If the egg emits a strong, unpleasant odor or a sulfur-like smell, it may be spoiled and should be discarded.

Tips for Storing Eggs

  • Refrigerate Promptly: Store eggs in the refrigerator as soon as possible after purchasing them to maintain their freshness and quality. The USDA recommends storing eggs in their original carton on a shelf in the refrigerator, rather than in the door, to ensure consistent temperature control.

  • Keep Eggs Cool: Store eggs at a temperature of 40°F (4°C) or below to slow the growth of bacteria and maintain their quality. Avoid storing eggs near sources of heat or fluctuating temperatures.

  • Use the Oldest Eggs First: Rotate your egg supply regularly and use the oldest eggs first to ensure that you're consuming them before they reach their expiration date.

  • Avoid Washing Eggs: Do not wash eggs before storing them, as washing can remove the protective coating on the eggshell and increase the risk of contamination. If necessary, gently clean dirty eggs with a dry cloth before refrigerating.

  • Store Away from Strong Odors: Eggs can absorb odors from strong-smelling foods in the refrigerator, so it's best to store them away from foods with strong odors, such as onions or fish.

Checking the freshness of eggs is essential for ensuring food safety and enjoying fresh, quality eggs. By performing visual inspections, water tests, float tests, and smell tests, you can determine if eggs are still good for consumption. Additionally, storing eggs properly in the refrigerator and following good food handling practices can help maintain their freshness and quality for longer. By following the guidelines outlined in this guide, you can confidently assess the freshness of your eggs and enjoy them safely in your favorite recipes.
