The market of ready-to-eat salads is experiencing a noticeable growth in Europe. commercial success these products linked to the growing demand for fresh, healthy and nutritionally valuable that can be consumed without preparation time are perceived as safe very high-quality products. Since they intended additional treatments, associated with high microbiological risk. aim this work was evaluate quality safety sold widespread supermarket chains Lazio, Italy, at packaging date, during shelf-life home-refrigeration. study also aimed determine differences between low, medium cost Salmonella spp., L. monocytogenes were chosen indicators specified by European regulations while total aerobic mesophilic bacteria Escherichia coli suggested national guidelines. Analyses performed following ISO standards parallel, evaluation bacteria, an alternative colorimetric system, MBS method, order propose simple, affordable accurate testing products, especially suitable small enterprises on-site analyses.
