Egg Packagers Exposure to Salmonella Enteritidis in Egyptian Laying Farms

摘要

The exposure of egg packagers to Salmonella enteritidis during handling and packing processes wasinvestigated in this study. S. enteritidis were isolated from swabs of laying hens fecal dropping(89/300), eggshells (249/420), repeated used egg carton packages (28/225) and egg packager hands(21/29). Pool isolates from caeca, ovary and oviduct were (21/68), (15/68) and (19/68) respectively.Therefore, egg packagers could expose to S. enteritidis infection during handling of contaminatedeggshells via hand to mouth. Repeated used carton egg packages may be considered as sources of S.enteritidis contamination for Salmonella free eggs and hands. Possible modes of control wererecommended.
