Abstract We assessed the interference of a complex food microbiota, present in Minas artisanal cheese (MAC) produced in the Serro region, on the performance of enumeration protocols for lactic acid bacteria (LAB) and staphylococci. Initially, 140 isolates were obtained from 6 Serro MAC samples and plated for enumeration of LAB (3 variations of MRS, M17 and Petrifilm™ LAB) and staphylococci (Baird–Parker and Petrifilm™ STX); some target isolates did not grow or present atypical morphologies in their selective protocols. Then, Serro MAC samples (n = 55) were obtained and plated for LAB and staphylococci based on the same protocols: 2569 isolates were obtained from LAB and 1164 from staphylococci protocols: Petrifim™ LAB presented the highest frequencies of LAB-confirmed colonies, as Petrifilm™ STX for staphylococci (p
