Recovery of Salmonella from eggshell wash, eggshell crush, and egg internal contents of unwashed commercial shell eggs in Australia.

摘要

The experiment was conducted to study the prevalence of Salmonella spp. on the eggshell surface, eggshell membranes or pores, and in egg internal contents from unwashed eggs collected from commercial caged layer farms in Australia. Eggshell rinsate, shell crush, and egg internal contents (yolk and albumen) of eggs were processed for Salmonella spp. Salmonella Infantis and Salmonella subspecies 1, serotype 4,12:d were isolated from the eggshell surface. Salmonella spp. were not isolated from any eggshell crush or egg internal contents. It would appear that the occurrence of Salmonella in the Australian egg industry is low.
