MICROBIOLOGICAL EVALUATION OF THE QUALITY OF PACKAGED WATER – WITH ADDED SALTS – IN 20 L PET AND PP BOTTLES IN THE STATE OF CEARÁ (A CASE STUDY)

In this study, microbiological analyses were performed with the aim of researching the following microorganisms described in Normative Instruction No. 161 of ANVISA, Total Coliforms, E. coli, Pseudonomonas aeruginosas and Enterococcus spp in water added with salts packaged in PET and PP bottles with a capacity of 20 L. Under the same analysis conditions, the results for the PP bottles were unsatisfactory with 100% presence of Total Coliforms and Pseudonomonas aeruginosas, while in the 20-liter PET packaging all the results were satisfactory, that is, with the absence of all microorganisms of IN No. 161 of ANVISA.
