I Thought the White String in My Egg Was a Worm – Here’s What It Really Is

Yes! The presence and firmness of the chalaza can give a clue about the egg’s freshness:

  • Thicker, more prominent chalaza: Typically indicates a fresher egg.
  • Fainter or less visible chalaza: May indicate an older egg, though still safe if stored properly.

Eggs with a pronounced chalaza are generally preferable for recipes where the yolk must remain intact, like poached eggs or soft-boiled eggs.

How to Handle Eggs With a Chalaza

  • For cooking: Simply crack the egg as usual. The chalaza will not interfere with most dishes.
  • For presentation: If making custards, flans, or delicate desserts, you can gently remove the chalaza with a spoon or fork.
  • For nutrition: There’s no need to remove it — the chalaza contains the same proteins as the rest of the egg white.

Safety Considerations

While the chalaza itself is harmless, general food safety practices for eggs should still be followed:

  1. Check for freshness: Perform the water float test if uncertain. A fresh egg sinks; an old egg floats.
  2. Inspect before use: Look for cracks, discoloration, or foul odor.
  3. Store properly: Keep eggs refrigerated to maintain freshness and reduce bacterial growth.
  4. Cook thoroughly: Cooking eggs fully minimizes the risk of foodborne illness.

Remember, the chalaza is not an indicator of contamination or spoilage. Even if it looks odd, your egg is perfectly safe to eat.
