Effect of Time and Temperature on Growth of Salmonella enteritidis in Experimentally Inoculated Eggs

Abstract
Influence of time and temperature on Salmonella enteritidis multiplication in expertimentally injected eggs was examined. There was an increase in the number of S. enteritidis with the increase in temperature of egg storage. There was less increase of S. enteritidis in eggs stored at 4 C than in eggs held at temperatures higher than 4 C (P < 0.05). These results suggest a possible method for monitoring commercial eggs for the presence of S. enteritidis. It was concluded that the chances of recovery of S. enteritidis can be increased 106-fold or more by holding the eggs at temperatures of 21 or 27 C for more than 20 days and culturing their contents.
