Abstract: This disclosure relates to techniques to sanitize eggs. More specifically to sanitizing eggs in a manner such that damage to the cuticle of the egg during sanitization is reduced or eliminated. A method includes the activation of photoactivated sanitizing agent with an appropriate wavelength of light at an intensity that eliminates, reduces, or slows the production of, pathogens on the shell of an egg. The photoactivated sanitizing agent can include an exogenously-applied photoactivated sanitizing agent and an optional photosensitizer, which can be activated with light having a wavelength known to activate the exogenously-applied photoactivated sanitizing agent. The photoactivated sanitizing agent can include an endogenously-derived photoactivatable compound. Light in the Soret band can be utilized to activate the endogenously-derived photoactivated sanitizing agent.
