### Recovery Ratio of Bacteria from Contaminated Samples  
The average number of bacteria reisolated from the contaminated poultry meat samples varied from 5.966 log CFU \(\times\) g\({}^{-2}\) for \(S\). Enteritidis strains to 6.395 log CFU \(\times\) g\({}^{-2}\) for \(C\). \(L\). _monocytogenes_ strains (Figure 2). No significant differences between individual strains of the examined species were noted. The C ratio, describing the effectiveness of the bacteria recovery from the contaminated food samples, ranged from 0.709 (\(S\). Enteritidis strain 2) to 0.822 (\(L\). _monocytogenes_ ATCC 1911), but these differences were not statistically significant. Figure 1: The average number of bacteria recovered from the biofilm (CJE—_Campylobacter jejuni_ strains, LMO—_Listeria monocytogenes_ strains, SENT—_Salmonella_ Enteritidis strains; a,b,c—values marked with different letters differ statistically significantly). Figure 2: The average number of _Campylobacter jejuni_ (CJE), \(L\). _monocytogenes_ (LMO), and _Salmonella_ Enteritidis (SENT) isolated from the contaminated meat sample (M), glass surface after contact with the meat sample (I), non-radiant catalytic ionization (RCI)-treated (-RCI) glass surface, RCI-treated (RCI+) glass surface in experimental variant I (a,b,c—values marked with different letters differ statistically significantly). Assessment of the Effectiveness of Surface Disinfection Using Radiant Catalytic Ionization during Bacterial Attachment (Experimental Variant I)  
In the case of experimental variant I, the average number of bacteria reisolated from the glass surface after 12 h contact with the meat sample ranged from 4.332 log CFU \(\times\) cm\({}^{-2}\) for \(S\). Enteritidis strains (from 4.182 log CFU \(\times\) cm\({}^{-2}\) for \(S\). Enteritidis strain 2 to 4.448 log CFU \(\times\) cm\({}^{-2}\) for \(S\). Enteritidis strain 1) to 4.837 log CFU \(\times\) cm\({}^{-2}\) for \(L\). _monocytogenes_ strains (from 4.823 log CFU \(\times\) cm\({}^{-2}\) for \(L\). _monocytogenes_ strains ATTC and 2 to 4.864 log CFU \(\times\) cm\({}^{-2}\) for \(L\). _monocytogenes_ strain 1). The differences were not statistically significant (Figure 2). In all cases, no significant differences were noted between strains of the tested species. After 24 h, the bacteria count on the glass surface not subjected to RCI treatment remained at a similar level. The average number of bacteria reisolated from the glass surface for \(C\). _ jejuni_, \(L\). _monocytogenes_, and \(S\). Enteritidis was 4.681 log CFU \(\times\) cm\({}^{-2}\), 4.810 log CFU \(\times\) cm\({}^{-2}\), and 4.285 log CFU \(\times\) cm\({}^{-2}\), respectively (Figure 2). The number of \(C\). _ jejuni_ varied from 4.492 log CFU \(\times\) cm\({}^{-2}\) (strain 2) to 4.778 log CFU \(\times\) cm\({}^{-2}\) (strain 1), \(L\). _monocytogenes_ from 4.795 log CFU \(\times\) cm\({}^{-2}\) (strain ATCC) to 4.838 log CFU \(\times\) cm\({}^{-2}\) (strain 1), and \(S\). Enteritidis from 4.138 CFU \(\times\) cm\({}^{-2}\) (strain 2) to 4.401 log CFU \(\times\) cm\({}^{-2}\) (strain 1). Application of RCI for 24 h resulted in a statistically significant decrease of \(C\). _ jejuni_ (varied from 1.192 CFU \(\times\) cm\({}^{-2}\) for strain 2 to 1.308 CFU \(\times\) cm\({}^{-2}\) for ATCC strain), \(L\). _monocytogenes_ (varied from 1.678 CFU \(\times\) cm\({}^{-2}\) for ATCC strain to 1.811 CFU \(\times\) cm\({}^{-2}\)), and \(S\). Enteritidis (varied from 1.646 CFU \(\times\) cm\({}^{-2}\) for ATCC strain to 1.708 CFU \(\times\) cm\({}^{-2}\) for strain 1). The average number of bacteria reisolated in this experimental variant was 1.258 log CFU \(\times\) cm\({}^{-2}\) for \(C\). _ jejuni_, 1.764 log CFU \(\times\) cm\({}^{-2}\) for \(L\). _monocytogenes_, and 1.683 log CFU \(\times\) cm\({}^{-2}\) for \(S\). Enteritidis (Figure 2). The differences between species were not statistically significant.
