Small layer flocks with <3,000 birds are currently exempted from the Final Egg Safety Rule of the Food and Drug Administration which was implemented with the aim of reducing egg-associated Salmonella Enteritidis (SE) illness. In this study, shell eggs from small flocks were tested to estimate the prevalence of SE in these eggs.
