  • Virulence of layer farm or egg associated Salmonella isolates

    2 About RDThis research was conducted to evaluate the virulence of Salmonella serovars commonly isolated from egg layer farms, through a study of the pathogenesis of egg/layer farm-related Salmonella serovars in a well-differentiated human intestinal cell culture model (in vitro) followed by a mouse model (in vivo). The study also investigated the ability ofSalmonella serovars to colonise the chicken oviduct organ cultures developed from Salmonella free laying hens. The Salmonella serovars were classified as high, medium and low invasive serovars. The genome of selected high, medium and low Salmonella serovars was also studied.

  • Salmonella control in layer chickens


    1US091The objectives of this project were to determine the capability to restrict Salmonella colonisation of and Salmonella shedding from layer chickens after differing vaccination regimes using live and inactivated Salmonella vaccines. These results were analysed to identify cost effective vaccination regime(s) to limit and achieve a reduction of Salmonella intestinal colonisation in commercial layer chickens in Australia.

  • An Egg: Salmonella Quantitative Risk Assessment Model

     A quantitative risk assessment of salmonella contamination in Australian eggs, with the goal of developing a tool to determine how changes in industry practices may impact on the occurrence of salmonellosis in humans.

  • Through-Chain Salmonella Risk Identification

    Salmonella posters on farm collectionAECL conducted a program of consultation with key through-chain stakeholders over a period of 12 months, to explore and document the public health risks associated with all aspects of egg production, from on-farm through to egg/egg product handling and hygiene. This work focused on the presence of Salmonella spp. The aim of the consultation has been to support stakeholders to reduce Salmonella load through-chain, through the compilation of comprehensive information about Salmonella and Salmonella risk identification and management.

  • Distribution and expression of the 14 kDa fimbrial gene among Salmonella Enteritidis isolates and potential as diagnostic and epidemiological tools

    This 12-month study (1993-1994) aimed to capitalise on prior observations and develop a novel strategy for rapid identification of Salmonella enterica serovar Enteritidis in egg and egg products based on detection of DNA sequences encoding SEF14. The results of this small study indicated that opportunity exists to use either Polymerase Chain Reaction (PCR) or antibody based techniques directed at the sefA gene or the SefA pilin sub-unit protein as techniques for rapid detection of S. Enteriditis strains.

  • The significance of Salmonella, particularly S. Infantis, to the Australian egg industry

    UQ 19EAThis study was to expand upon previous survey work of layer flocks in Queensland by conducting longitudinal and point-in time surveys of Salmonella faecal carriage and feed contamination on farms.

  • Food-borne pathogens and animal botulism issues surrounding the on-farm composting of layer chicken waste and mortalities – a review

    1EC083

  • The Culinary Uses of Eggs

    EggInBowl A key challenge for the egg industry is food safety, particularly with regard to the presence of Salmonella species and their potential to cause human salmonellosis. Understanding the different uses of eggs in food and the preparation method used provides non-food sector stakeholders with an initial reference point to consider potential Salmonella risk.

  • National Food Safety Risk Profile of Eggs and Egg Products

    This report set out to identify the following; hazards that enter any point of the food chain for eggs and egg products, potential management strategies for the identified high risk hazards, and product/pathogen combinations in which further risk analysis might be required by risk managers.
