Leading Research: in Food Safety
Food safety is a key issue for both consumers and egg farmers and is critical to maintaining confidence in eggs as a staple food.
Work to date has demonstrated that it is possible to minimise risks arising on-farm to a very low level and this work will continue through both research and communications activities.
There remains an even greater potential to assist in managing food safety risks arising in the post-farm egg value chain by continuing to facilitate dialogue between the egg industry, food safety regulators and end-users of eggs and egg products.
The positive health and nutritional benefits of eggs to humans will continue to be characterised and disseminated. By investing in RD&E we intend to reduce food safety issues, increase consumer confidence and consumption and enhance industry credibility.
Key Resources
Current Research
Investigating improved rodent control strategies
Researchers will work closely with industry to develop innovative, economical strategies for efficient rodent management. The strategies will be trialled on participating egg farms and the outcomes and learnings will be communicated to industry.
Review of literature for understanding eggs contamination during cold-chain transportation
This scope of this project is to determine if various lower storage temperatures will mitigate the
growth of Salmonella Enteritis and Salmonella Typhimurium. The work will involve literature
review, use of specific scientific databases, and collaboration with scientists to ensure accurate
information is gathered.Protecting Australia's poultry using genetic restoration
In this proof of concept study, researchers will attempt to embed genetic material from other poultry species into the layer hen genome. The specific genetic material relates to Avian influenza resistance so there is the potential that it could do the same for the layer hen.
Completed Research
Traceability for the egg industry
Robust traceability systems are critical to ensuring that in the event of egg quality and food safety issues, the correct farms, specific production areas or sheds can be efficiently identified, and steps taken to rectify concerns.
Evaluation of the duration of immunity induced by a vaccination program against Salmonella Enteritidis 7A in laying hens in Australia (Stage 2).
In this research, a combination of live Salmonella Typhimurium and autogenous Salmonella Enteritidis (SE) vaccine did provide layers with a long- term humoral immune response, but did not prevent the shedding of Salmonella.
Surveillance for antimicrobial resistance in enteric commensals and pathogens in the Australian commercial egg industry
Funded by the Commonwealth government, the Australian egg industry investigated the levels of antimicrobial resistance of E. coli and Enterococcus on egg farms.
This research helps the egg industry to understand how effectively antimicrobials are currently being used.Promotion of competitive exclusion by ‘good’ bacteria against Salmonella
To investigate one way of biologically controlling Salmonella, potential control organisms were isolated from the layer farm environment by demonstration of inhibition to a single Salmonella Typhimurium strain. The ability of the isolates to inhibit Salmonella growth using the agar overlay method was assessed, then the ability of the isolates to competitively exclude Salmonella attachment to stainless steel coupons was assessed by the use of pre-formed biofilms.
Evaluation of vaccination program options against Salmonella Enteritidis 7A in laying hens in Australia
This project tested three different vaccination programs for their efficacy in Salmonella Enteritidis (SE) prevention in laying hens. The results of this study indicated that SE control is possible using a combination of the current registered live Salmonella Typhimurium (ST) vaccines and an SE killed autogenous vaccine.
In Stage two of this project hens vaccinated with the ST + SE program were challenged 35 weeks after their second vaccination. Results indicated that vaccinated hens had a sustained humoral immune response, but were no less likely to be infected with SE long- term than non-vaccinated hens.Traceability Technology Desktop Review

Antimicrobial resistance surveillance in Salmonella isolates from environments on Australian commercial egg farms
This project was conducted to identify the most appropriate mechanisms for obtaining and performing antimicrobial susceptibility testing on Salmonella isolates obtained from Australian layer shed environments.
