--- The purpose of this study was to evaluate the degree of faecal contamination in three vegetables of major raw consumption that are selled in four importants wholesale markets in Lima city. A total of 180 samples, 15 lettuce (Lactuca sativa) samples, 15 cabbage (Brassica oleracea) samples and 15 spinach (Spinacea oleracea) samples from La Parada, Ramón Castilla, Ceres and Caquetá were collected. Samples were processed using the Most Probable Number method for faecal coliform and E. coli Type I (Typical) detection and count, plus Absence/Presence test for Salmonella. In this study 18.9% and 56.7% from all vegetables, and 22.2% and 64.4% of vegetables from markets 1 and 3 displayed faecal coliforms levels higher than those were established by ICMSF (100) and MINSA (10), respectively. In addition, 2.2% vegetables from the market 4 displayed E. coli Type I (Typical) levels higher than that was established by ICMSF and MINSA (10). In both cases, spinach had the higher contamination. About Salmonella spp., 10% all vegetables were contaminated, standing out the cabbage and the market 2 displayed the higher percentage (20%). Markets 3 and 4 displayed vegetables with higher percents of total acceptance, and the market 2 those with higher percents of reject.
