| Abstract (English): | The incidence of L. monocytogenes in tomatoes and coriander obtained from three different markets, during eight weeks were determined. 192 samples were evaluated: 96 of tomatoes, and 96 of coriander. The isolation of L. monocytogenes was performed using COVENIN 3718:2001. The data were analyzed by SPSS version 12.0. Kolmogorov Smirnov, Mann Whitney U, Kruskal Wallis U test; Spearman's correlation were applied, and p<0.05 significance level was applied. It was not found significant differences between the medias values and standard deviations of Most Probable Number (MPN) of Listeria spp to tomatoes and coriander during the eight weeks of recollection in the markets; neither between the distributions of MPN of tomatoes and coriander from the markets (Chi²=5,233 p<0,073; Chi²=1,624 p<0,444 respectively) neither the samples per weeks (Chi²=6,547 p<0,477; Chi²=2,667 p<0,914 respectively). In the number of MPN between tomatoes and coriander both distributions were significant different according to test U Mann Whitney U=3040,5 (Z=-4,216 p<0,0001). It was found statistical significance (p<0,001) between the number of MPN of tomatoes and coriander. The presence of Listeria spp in tomatoes was 41,66% (25,0% L. monocytogenes and 16,7% L. ivanovii); in coriander 77,08% (36,5% L. monocytogenes, 33,3% L. ivanovii and 7,3% L. seelige.). We concluded that the high level of L. monocytogenes in tomatoes and coriander is independent of the markets store; we see the necessity of a microbiological control on the irrigation system, collection and distribution to ensure the quality of the product.

| Abstract (Spanish): | Se determinó la frecuencia de L. monocytogenes en tomates y cilantro, de tres diferentes supermercados, ubicados en el Municipio Valencia, Estado Carabobo, durante ocho semanas. Se evaluaron 192 muestras: 96 de tomates y 96 de cilantro. Procesamiento y análisis microbiológico, según Normas Industriales COVENIN 3718:2001. Paquete estadístico SPSS versión 12.0. Se aplicó prueba de Kolmogorov Smirnov, test de U Mann Whitney y Kruskal Wallis y correlación de Spearman. Nivel de significancia (p<0,05). No se encontraron diferencias significativas entre los valores medios y desviación estándar en el número del Numero Mas Probable (NMP) de Listeria spp para tomates y cilantro, durante las ocho semanas de recolección en los tres supermercados; ni tampoco entre las distribuciones de NMP en tomates y cilantro de los tres supermercados (Chi2=5,233 p<0,073; Chi²=1,624 p<0,444 respectivamente); ni entre las muestras por semana (Chi²=6,547 p<0,477; Chi²=2,667 p<0,914 respectivamente). Se encontró diferencia significativa (p<0,0001), en las diferencias de distribución de NMP entre tomate y cilantro y en el número de NMP entre tomates y cilantro (p<0,001). La presencia de Listeria spp en tomate fue 41,66% (25,0% L. monocytogenes y 16,7% L. ivanovii); en cilantro 77,08% (36,5% L. monocytogenes, 33,3% L. ivanovii, 7,3% L. seeligeri). Se concluye que el elevado porcentaje encontrado de L. monocytogenes en tomates y cilantro, es independiente del supermercado de expendio; se evidencia la necesidad de un control microbiológico a nivel del sistema de riego, recolección y distribución, para asegurar la calidad del producto.
