Farm Eggs treated against Salmonella

The purpose of eggshell disinfection is to remove the eventual bacterial contamination found on eggs. Such bacterial contamination may reach the eggshell from outside sources (e.g. litter or housing microclimate) mostly after the phase of egg formation. Bacterial presence on the eggshell means no problem but the bacteria may enter the egg if the cuticle layer is damaged. Further sources of hazard may emerge when eggs are not washed before use and a piece of cracked eggshell contaminates the food or when the contamination is transferred by touching other foodstuffs.
