Technical Abstract: There is a strong association between the incidence of human illness and the prevalence of Salmonella Enteritidis in commercial egg-producing poultry. Although most egg-associated disease around the world has been attributed to S. Enteritidis, other serovars are sometimes implicated. The deposition of S. Enteritidis within the edible interior contents of eggs results from the colonization of reproductive tissues in systemically infected hens. Environmental conditions directly affect opportunities for Salmonella introduction, transmission, and persistence in laying flocks. Many important environmental influences are shaped by the various housing systems used in the commercial egg industry. Substantial resources from both government and private industry have been invested in comprehensive S. Enteritidis testing and risk reduction programs for egg-producing poultry. A strategy involving multiple interventions throughout the egg production cycle is generally recommended as the most effective approach for controlling S. Enteritidis. Controlling temperature is critical for restricting Salmonella growth inside eggs.
