The purpose of this thesis is to investigate the standards of the hygiene and sanitation in the meat processing. The major objective is to evaluate the effectiveness of sanitation in terms of microbial contamination. In the first part of thesis there was processed information about European and Czech legislation dealing with food safety. Inspection authorities that supervise legislative requirements were described. Also, there were explained the systems that ensure hygiene good practice, where the work dealt with sanitation procedures and HACCP system. In the end, indicator microorganisms are characterized. The second part describes the procedure to determine the level of hygiene standards. According to the potential risk there were selected places, which were monitored by swabbing the incidence of total viable count, Enterobacteriaceae and molds and yeasts. On the basis of the obtained results the selected places were compared and afterwards the efficiency of the sanitation was evaluated. These results were compared with Government Decree No. 289/2007 Coll. It can be claimed that there was no statistically significant difference (p> 0.05) in the total viable count, Enterobacteriaceae and yeast and molds at individual locations or during sampling at different times after sanitation. From the average results (n = 3) there was detected only one place, where the maximum value stated in Government Decree No. 289/2007 was exceeded. However, this occurred only in the total viable count. Contamination places of yeasts and molds were not detected in every place (only in some of the places) and in terms of detected places the contamination did not reach critical values. Contamination of Enterobacteriaceae was found minimally. Effective sanitation, mainly cleaning and disinfection of machinery, equipment and working tools in the food processing, is one of the most important instruments in the ensuring hygiene and food safety.
