This review describes different strategies which have been explored to reduce food safety risks associated with egg contamination. The first one aims to reinforce the physical (eggshell) and chemical (antimicrobial proteins) protective mechanisms of eggs by identifying genes that code for proteins involved in egg protection. The following step is to explore phenotypic variability in egg protection against Salmonella related to environmental factors during egg production and storage and the feasibility to select hens with superior eggshell strength or anti-microbial alleles using marker assisted selection. A complementary approach is to eliminate eggs at risk by improving the technology for egg grading using non-invasive methods to enhance the detection of eggs with the greatest risk to the consumer. Finally, the risk can be controlled by reducing the degree of egg contamination by developing innovative egg decontamination treatments as alternatives to egg washing. We explored the decontamination efficiency of hot air, gas plasma sterilization, modified atmosphere packaging or chitosan treatment of eggs. These approaches were developed under two European programmes, Eggdefence and Rescape.

Abstract
This review describes different strategies which have been explored to reduce food safety risks associated with egg contamination. The first one aims to reinforce the physical (eggshell) and chemical (antimicrobial proteins) protective mechanisms of eggs by identifying genes that code for proteins involved in egg protection. The following step is to explore phenotypic variability in egg protection against Salmonella related to environmental factors during egg production and storage and the feasibility to select hens with superior eggshell strength or anti-microbial alleles using marker assisted selection. A complementary approach is to eliminate eggs at risk by improving the technology for egg grading using non-invasive methods to enhance the detection of eggs with the greatest risk to the consumer. Finally, the risk can be controlled by reducing the degree of egg contamination by developing innovative egg decontamination treatments as alternatives to egg washing. We explored the decontamination efficiency of hot air, gas plasma sterilization, modified atmosphere packaging or chitosan treatment of eggs. These approaches were developed under two European programmes, Eggdefence and Rescape.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
