Synergistic antibacterial effect of DNase I and eugenol against Salmonella Enteritidis biofilm on smoked duck and food contact surfaces

Salmonella Enteritidis is one of the major pathogens causing food poisoning worldwide. The persistent nature of this pathogen causes significant food safety and sanitization challenges. As an alternative and efficient approach, the present study investigated the effect of DNase I and eugenol to cont...

Description
Summary:Salmonella Enteritidis is one of the major pathogens causing food poisoning worldwide. The persistent nature of this pathogen causes significant food safety and sanitization challenges. As an alternative and efficient approach, the present study investigated the effect of DNase I and eugenol to control S. Enteritidis biofilm formation on stainless steel (SS), polyethylene terephthalate (PET), and smoked duck surfaces. Individual DNase I and eugenol treatments showed biofilm reductions of >1 and 1.9 log CFU/Cm2 on SS surfaces within 2 h, respectively. However, the combined DNase I and eugenol treatment resulted in 4.4 log biofilm reduction of S. Enteritidis wild cocktail on PET and SS surfaces, respectively, within 30 min, which was significantly higher than the individual treatments (p
