The survival of salmonellas in shell eggs cooked under simulated domestic conditions

Abstract

Strains ofSalmonella enteritidis, S. typhimurium and S. senftenberg inoculated into the yolks of shell eggs were found to survive forms of cooking where some of the yolk remained liquid. Survival was largely independent of the size of the initial inoculum. The organisms also grew rapidly in eggs stored at room temperature and after 2 days the number of cells per gram of yolk exceeded log 8·0. With this level of contamination viable cells could be recovered from eggs cooked in any manner. © 1989, Cambridge University Press. All rights reserved.
