Abstract

Innovative diagnostic methods were developed for the detection and quantification of Listeria monocytogenes and Escherichia coli O157:H7 in minimally processed fresh cut fruits and vegetables. The aim of the present study was to validate the technical efficiency of these methods and evaluate their efficacy and viability for routine analysis. To this purpose, ready-to-eat fresh fruits and vegetables were collected throughout the production chain. A multidisciplinary approach, including a newly developed ELISA method compared to ISO procedures, was applied to detect the pathogenic bacteria after harvesting, processing and shelf-life. Results obtained exhibited the technical efficiency of the developed methods showing similar sensitivity, specificity, negative predictive values and negative likelihood ratios.
