This study assessed the microbiological quality of pescutan yogurt, which is a concentrated variety of yogurt produced by traditional methods and is available for sale in the public markets in the Sivas region. For this purpose, 30 pesticide samples were collected from the center and districts of Sivas and microbiological analyses were carried out according to the International Organization for Standards (ISO) methods. The analyses include the total aerobic mezophyllic bacteria (TAMBs), may-chicken, koliform group bacteria, Escherichia coli and coagulase positive staphylococcus countings. In addition to these bacterial groups, examples of pathogenic bacteria include Listeria monocytogenes and Salmonella spp. It was assigned. The results of the analyses found that in samples the TAMB and the Maya-crow number were 6.74±0.66 and 7.11±1.10 log kob g-1 respectively. None of the samples contain the koliform group of bacteria, E. coli, Salmonella spp. L. monocytogenes is not identified. In the number of staphylococcus, 30 for example in 19 is Staphylococcus spp. The existence has been identified but none has been defined as coagulate positive S. aureus. The results obtained indicate that there are no pathogenic microorganisms or fecal contamination in pesticide samples. However, the high number of TAMBs and mayas in pescutane samples may indicate that hygiene conditions are not sufficiently provided in the production, storage or marketing stages.

In this study, microbial quality of the peskütan yoghurt which is a concentrated yoghurt type produced by traditional methods and sold in Sivas province public markets was assessed. For this purpose, 30 peskütan samples were collected from Sivas center and districts and microbiological analysis were performed according to the International Organization for Standardization (ISO) methods. The analysis aerobic bacteria (TAMB), yeast-mould, coliform group bacteria, Escherichia coli and coagulase-positive Staphylococci counts. Besides these bacterial groups, Listeria monocytogenes and Salmonella spp. were also counted in samples. As a result of the analysis, TAMB and yeast-mould counts in the samples were found 6.74±0.66 and 7.11±1.10 log kob g-1 respectively. In none of the samples, coliform group bacteria, E. coli, Salmonella spp. and L. monocytogenes species were not detected. In the counting of Staphylococci, 19 of the 30 samples were determined as Staphylococcus spp. but none of them were identified as coagulase positive S. aureus. The results obtained indicate that there are no pathogenic microorganisms or fecal contamination in the peskütan samples. However, the high number of TAMB and yeast-mold in peskütan samples may indicate that hygienic conditions are not sufficiently at the production, storage or marketing stages.
