Abstract Aeromonas species are emergent pathogens that can recover of a great variety of foods. The objective of this investigation was to determine the frequency of Aeromonas spp. in fresh vegetables that are expended in Maracaibo. 150 samples were analyzed: 50 lettuce, 50 cilantro and 50 parsley. For the isolation alkaline peptone water (enrichment medium), ampicillin starch agar and DNasa- toluidine blue-ampicillin agar (selective media) were used. The identification was made by using biochemical tests. The frequency of Aeromonas spp. was of 37; (24,67%), being the coriander samples those that presented the biggest isolation number 24 (52,00%). A. caviae was the most frequent species 27 (72,97%), followed by A. hydrophila 10 (27,03%). These results evidence that the analyzed vegetables present high levels of contamination for Aeromonas that which indicates that they should take measures to minimize the microbiological risks that represent these foods for the consumers
