Impact of Different Layer Housing Systems on Eggshell Cuticle Quality and <i>Salmonella</i> Adherence in Table Eggs

The bacterial load on the eggshell surface is a key factor in predicting the bacterial penetration and contamination of the egg interior. The eggshell cuticle is the first line of defense against vertical penetration by microbial food-borne pathogens such as <i>Salmonella</i> Enteritidis...

description	The bacterial load on the eggshell surface is a key factor in predicting the bacterial penetration and contamination of the egg interior. The eggshell cuticle is the first line of defense against vertical penetration by microbial food-borne pathogens such as <i>Salmonella</i> Enteritidis.
