摘要：
The aim of present study was to verify the presence of microorganisms in natural orange juice samples collected in downtown Sao Paulo city and compare them with the current legislation. Three samples were collected of natural orange juices from different places of sale. Analyzes were performed to identify the presence of mesophile, yeast, and coliforms, using Tryptone Soy Agar (TSA), Potato Dextrose Agar (PDA,) and presumptive and confirmative coliform tests. The values found were higher than recommended for mold, yeast, and bacteria. Fecal coliforms were not present in any samples, with the presence of 50% for the presumptive test and 33.3% in the confirmative test for total coliforms. The results indicate the need to adopt best practices in food manipulation.
