The present study focused on determining the microbiological load of watering water and vegetables grown in the market gardening area of SAGBAYA, Urban Commune of Faranah. The microbial germs contained in water and vegetables were determined by the membrane filtration method. The results of microbiological analyzes of vegetables indicated variations depending on the locations of the wells and their sources of pollution. During the two vegetable production seasons, the results showed that except for the water from the borehole, that of the most exposed wells was highly contaminated. The water used during the 2024 season, unlike the previous one, all contained total and fecal coliforms whose values oscillated respectively between 15 and 159 CFU/100ml and 9 to 126 CFU/100ml. Of the vegetables harvested, although some samples were free, carrots contained more pathogens than cabbage and lettuce in both well and borehole water. The microbiological charges in CFU/100 ml of cabbage organs varied from 2 to 85 in total coliforms and from 2 to 56 in fecal coliforms; 3 to 75 in total coliforms and 1 to 56 in fecal coliforms in carrots, finally 3 to 85 in total coliforms and 1 to 66 in fecal coliforms in lettuce. Most water and vegetables have microbiological charges exceeding the required standards, hence the consumption of these vegetables without treatment constitutes health threats to consumers.
Author Keywords: well, irrigation water, total and fecal coliforms, market gardening, Faranah-Guinea.

Abstract: (french)
La présente étude a porté sur la détermination de la charge microbiologique des eaux d’arrosage et légumes cultivés dans le domaine maraîcher de SAGBAYA, Commune Urbaine de Faranah. Les germes de microbes contenus dans les eaux et légumes ont été déterminés par la méthode de filtration sur membrane. Les résultats des analyses microbiologiques des légumes ont indiqué des variations selon les emplacements des puits et de leurs sources de pollution. Durant les deux saisons de production maraîchère, les résultats ont montré qu’excepté les eaux du forage, celles des puits les plus exposées étaient fortement contaminées. Les eaux utilisées pendant la saison 2024 contrairement à celle précédente contenaient toutes, des coliformes totaux et fécaux dont les valeurs oscillaient respectivement entre 15 et 159 UFC/100ml et 9 à 126 UFC/100ml. Des légumes récoltés, bien que certains échantillons étaient indemnes, les carottes renfermaient plus de pathogènes que le chou et la laitue aussi bien avec les eaux de puits qu’avec celles du forage. Les charges microbiologiques en UFC/100 ml, des organes du chou ont varié de 2 à 85 en coliformes totaux et de 2 à 56 en coliformes fécaux; 3 à 75 en coliformes totaux et 1 à 56 en coliformes fécaux au niveau des carottes, enfin 3 à 85 en coliformes totaux et 1 à 66 en coliformes fécaux dans la laitue. La plupart des eaux et légumes ont des charges microbiologiques dépassant les normes requises d’où, la consommation de ces légumes sans traitements constitue des menaces sanitaires des consommateurs.
