Project

Egg Quality & Risk of Food Borne Pathogens

Summary

The eggs produced in Australia are of very high quality.  However, it is widely recognized that bacteria such as salmonella are a potential threat to the egg industry so the industry needs to be vigilant in monitoring the presence of these bacteria on or in eggs.  Although there is the potential for vertical transmission of bacteria (as has been shown to occur for Salmonella enteritidis), it is generally accepted that horizontal transmission is the most likely source of contamination of shell eggs with most bacteria.  It is difficult for bacteria to move across an intact good quality egg shell.  However, even small defects in the egg shell may provide the means for bacteria to move into the egg contents. Translucent eggs and microcracks were observed during egg quality analysis of eggs collected from various farms across Australia. The role of the phenomenon known as “translucency” and the presence of microcracks in reducing egg shell strength is still poorly defined. It is not clear to what extent these shell defects increase the likelihood that bacteria on the outside of the shell will move into the egg contents.  Egg processing facilities, whether they use visual candling or electronic inspection and crack detection, allow through eggs with some small cracks and the risk that such eggs pose to product safety is uncertain.  The proposed project will document the incidence of translucency in egg shells and microcracks.  It will also evaluate the extent to which these features increase the likelihood of bacteria (Such as Salmonella and E coli) penetrating the egg shell.
