Súhrn: Microbial contamination of production surfaces in small and medium-sized ewes’ milk and meat processing enterprises in Slovakia was studied. Staphylococci and enterococci dominated in ewes’ milk processing small and medium-sized enterprises (SME) on stainless steel at 103 104 CFU•cm-2 as well as on plastic surfaces at 101–103 CFU•cm-2, and in meat processing SME at 101 102 CFU•cm 2 on both types of surfaces. In both types of SME, a reduction only by 0–1 orders of magnitude was observed in these contaminants after sanitation of stainless steel and plastic surfaces. Coliforms were not significantly resistant to sanitation. Eleven Staphylococcus isolates from ewes’ milk processing SME and 8 isolates from meat processing SME were found to form biofilm. A few biofilm forming strains were isolated also among enterococci and coliforms. Pseudomonads were isolated only from one ewes’ milk processing SME, but these were found to form biofilm and to resist sanitation. The levels of contamination of production surfaces in ewes’ milk and meat processing SME in Slovakia were found to be considerably high and the effectiveness of sanitation was assessed to be considerably low.
