La armonización y la estandarización en microbiología molecular alimentaria : los casos de Listeria monocytogenes y Salmonella spp

Abstract

Microbial analysis is a prosperous, lucrative and growing industry, with a global market of more than 2 billion analyses performed in 2014. Food microbial testing comprised more than 966 million analyses in 2013, with annual global revenues of $3 .05 billion for the 2,350 food contract test labs worldwide. It is evident that the food industry requires the service of third party food contract labs to address its main demands: selectivity of the methodology, short time to delivery of fit for purpose final results, and reduction of the associated cost of analysis through efficient working practices. As a result, any alternative methodology, and in particular molecular microbial diagnostic methods must try to meet these objectives. For that two major actions are needed: the harmonization of the route from the design and development of a molecular microbial diagnostic method to its final effective implementation in routine food labs, and global effort towards standardization of molecular methods. In this presentation, we review the current situation on harmonisation and standardization of molecular microbial diagnostic method, and the particular cases of Listeria monocytogenes and Salmonella spp. will be presented.
