Because the egg white, or the albumen, contains natural antimicrobial properties, eggs are excellent for use in pharmaceutical products. Eye drops, toothpaste and throat lozenges to fight bacteria have been made from egg ingredients. Eggs are used in products that deliver drugs to tumors. Hospitals use eggs in diagnostic tests to identify some viruses and diseases.
Eggs are among the safest food available to humans.
The shell protects the egg interior from bacteria. Another membrane sticks to the shell and yet another membrane surrounds the egg white to further protect the interior of the egg. The egg white itself contains natural antimicrobial properties. The chalaza is a pair of spiral bands anchoring the yolk to the centre of the egg white. Very fresh eggs have very pronounced chalazas.
