Calidad microbiológica y bacterias enteropatógenas en vegetales tipo hoja
Abstract: To analyze the microbiological quality of leaf vegetables and the incidence of nteropathogenic bacteria, 150 samples (50 lettuce, 50 coriander and 50 parsley) collected in two supermarkets in Maracaibo, were studied. Total coliforms (TC) and Escherichia coli (EC) according to COVENIN guide...

Total coliforms (TC) and Escherichia coli (EC) according to COVENIN guideline N° 3276: 1997, were determined; for the identification of enteropathogenic bacteria (Salmonella, Aeromonas, Vibrio), enrichment and selective media were used.

The frequency of enteropathogens was 28%, with Aeromonas the most isolated genus (95.91%). Greater recovery of enteropathogens was obtained from coriander (40.00%), followed by the parsley (34.00%) and lettuce samples (20.00%); A. caviae was the most recovered specie (59.18%) followed by A. hydrophila (30,62%). Salmonella spp were recovered in 2 samples (4.08%). The presence of enteric indicators (TC and EC) and enteropathogenic bacteria suggests that the sanitary condition of the leafy vegetables is inadequate and can be a source of gastroenteritis.
