The quality and control of treated drinking water (APTO) plays an important role, making it a disease transmission vehicle produced by pathogens such as Coliformes, Pseudomonas aeruginosa and Salmonella pp. In addition, the APTO is a product of high commercialization and distribution worldwide. It is important to determine its microbiological conditions in order to guarantee its safety. According to this, the objective of the present study was to: Evaluate the presence of Coliformes, Pseudomonas aeruginosa and Salmonella spp in 10 treated water companies, produced and commercialized in San José de Cúcuta, in the municipalities, Patios and Villa del Rosario. Materials and methods: Ten companies were selected, performing the analysis according to resolution 2115 of 2007, using the membrane filtration method, using Chromocult agar, Cetrimide and Standar Plate Count. For the determination of Salmonella spp., The horizontal method was applied. The presence of mesophilic aerobes was identified in 38%, total coliforms in 27%, fecal coliforms in 23%, pseudomonas aeruginosa in 12% and salmonella in 0%. The samples analyzed showed significant results on the values allowed in resolution 12186 of 1991. These samples are a potential risk, which directly affects the health of the consumer. In fact, comprehensive control and control is required at all stages of processing and distribution of bottled treated water, in order to reduce the risks when consumed.
