| Sumario: | Ice cream, as it is a dairy product, can contain nutrients such as proteins, fats, sugars and vitamins, which makes it an excellent substrate for bacterial proliferation. The objective of this research was to microbiologically evaluate artisanal ice creams sold in São Luís - MA. Three samples were collected over a period of two months, in the location of (P1) Terminal Praia Grande, (P2) Praça Mauro Machado and (P3) Portinho in 2019, totaling 6 samples collected in appropriate plastic bags and stored in a Styrofoam box until analyzes were carried out in the UNICEUMA microbiology laboratory. To determine total coliforms and thermotolerant coliforms of fecal origin, the Pour-Plate method was used. The result is expressed as the number of Colony Forming Units (CFU/Ml). The results were compared to legislation standards. The presence of fecal or thermotolerant coliforms in ice cream samples varied in the month of September at the three points in dilutions 10-1 to 10-3 of P1 (1,310x10³ to 8.00x10³ CFU/mL) and P2 (1,250x103 to 2,430x103 UFC/mL), noting that growth varied at points 1 to 3 (formed between 9.20x103 and 4.600x103 UFC/mL), all points are above what is allowed by legislation (1000 UFC/m L RDC no. 12/01 /01). Ice creams are not safe for consumption and are not within Brazilian law. In conclusion, the research revealed unsatisfactory hygienic and sanitary conditions in the majority of artisanal ice cream shops sold in São Luís do Maranhão. |
