    The objective of this thesis was to determine the microbiological quality of food intended for human consumption in the district of Cercado de Lima between May 2017 and June 2018. The study was descriptive, observational, and cross-sectional. Ten food samples with heat treatment and ten without heat treatment were randomly selected and evaluated. Sample processing was carried out in the laboratories of Norbert Wiener University, where the incorporation count technique was used to determine the presence of mesophilic aerobic bacteria, total coliforms, and yeast-like fungi. The results were obtained and compared with the Sanitary Technical Standard NTS Nº 071 - MINSA/DIGESA - V.01. In the Colony-Forming Units (CFU) count, it was observed that both types of samples had the same percentage of mesophilic aerobic bacteria. However, the quantity of total coliforms found in foods without heat treatment was higher compared to those with heat treatment. A high percentage of yeast-like fungi was also found in both types of samples. It is concluded that foods without heat treatment presented elevated counts, which, in accordance with the Sanitary Technical Standard, makes them unfit for human consumption.
