Objective – To determine the presence of microorganisms in the beer can, collecting samples from three different groups of markets, divided into: G1 - Street vendors, G2 - Bars and G3 - Supermarkets in the city of Sorocaba / SP, totaling 33 samples with and without protective seal. Methods – All samples were inoculated in appropriate culture media, analyzing the growth level of each one and using the specific biochemical tests to identify the microorganism. Results – Of the 30 samples, excluding the 3 control samples, only 5 without the protective seal were positive, in three of them there was growth of Gram negative bacteria and in two there was growth ofGram positive bacteria. Conclusion– With the results obtained, it was possible to conclude that the use of the protective seal and the cleaning prior to consumption are effective to avoid bacterial contamination, since in none of these samples there was growth of microorganisms.
