Wow, according to Morcar's county extension officer, most people must be dumb as posts. We can't figure out how to wash eggs in warm water and detect cracks? The person quoting this rubbish has obviously never washed an egg.(the extension officer who is paid to read from reference books but certainly not paid to think) A hairline crack in an egg that I cannot detect with my eye does become visible when placed in very warm water, it bubbles. What's that old saying, where there's bubbles, there's a crack.
I wash eggs since I would not feel right sending off dirty eggs with my customers. I also keep stained or cracked eggs for myself, badly cracked go to the dog. I have never used soap, nor bleach, but bleach my little washing cloth and the designated wash bucket after each use. Air dry the cloth so no contamination happens from one day's eggs to the next.
