Hot air pasteurisation was investigated in the EU funded project named RESCAPE as innovative treatment for surface bacterial decontamination of table eggs. Possible side effects of the treatment on egg quality traits were also studied. The decontamination power of hot air was evaluated over one month on shell eggs experimentally inoculated with Salmonella Enteritidis, Escherichia coli or Listeria monocytogenes. The S. Enteritidis and L. monocytogenes populations on the surface of treated eggs showed a significant reduction in comparison to untreated ones. No statistically significant results were obtained comparing E. coli loads on treated and untreated eggs. No detrimental effects on quality traits immediately after the treatment as well as after 28 days of storage at 20°C were recorded.
