Samples were collected within three months (September, October, November 2014). Together 54 samples selected surfaces were collected. Each month six samples were collected using imprint method with Petrifilm plates on total count of microorganisms, 6 samples using imprint method with Petrifilm plates on the number of coliforms and 6 samples using sterile swab method. Samples were collected from the workbench, conveyor belt, cutting blades, meat grinder, wall and knife. Total viable counts (TVC) and coliform bacteria (CB) were determined in samples. The values of TVC in September obtained by swabbing method were higher than allowable limit in sample no. 1 (3.70×102 CFU.cm-2) and in sample no. 4 (3.35×101 KTJ.cm-2). The values of TVC obtained by Petrifilm plates were lower than 10 CFU.cm-2 in all samples. Values of CB obtained by Petrifilm plates were lower than 1 CFU.cm-2 in all samples, CB obtained by swabbing method was 1.6×101 CFU.cm-2 in sample no. 6. Values of TVC obtained in October by Petrifilm plates and also by swabbing method were higher than permissible limit (< 10 CFU.cm-2) in sample no. 2 and sample no. 4. Values of CB obtained by Petrifilm plates were lower than 1 CFU.cm-2 in all samples, CB obtained by swabbing method was 3,65×101 CFU.cm-2 in sample no. 3, value of CB obtained by swab method in sample no. 3 does not meet requirements of internal company standards. Values of TVC obtained in November by Petrifilm plates were lower than 10 CFU.cm-2 in all samples. TVC otained by swab method were 1,25×101 CFU.cm-2 in sample no. 3 and 3,25×101 CFU.cm-2 in sample no. 4. Samples were not in accordance with requirements of internal company standards. Values of CB obtained in November by Petrifilm plates and by swabbing method were after disinfection lower than 1 CFU.cm-2 in all samples.
