Title

ANTIBACTERIAL EFFECT OF SILVER NANOPARTICLES AGAINST FOUR FOODBORNE PATHOGENS

Abstract

 Background: There is increased demand for improved DISINFECTION methods due to microorganisms resistant to multiple antimicrobial agents. Numerous types of disinfectants are available with different properties; but the proper disinfectant must be carefully selected for any specific application to obtain the desired antimicrobial effect.Objectives: Antimicrobial effect of a commercial nanoSILVER product, NanoCid® L2000, against some foodborne PATHOGENs was evaluated. Materials and Methods: Minimum inhibitory concentrations (MIC) were determined by monitoring the growth of bacteria at 600 nm, after 24 hours incubation at 35oC. Minimum bactericidal concentrations (MBC) were determined based on 3 log decrease in the viable population of the PATHOGENs after incubation of nutrient agar plates at 35oC for 24 hours. The required exposure time for 3 log reduction in the viable population of the tested PATHOGENs was determined as the minimum exposure time for efficient bactericidal activity.Results: The MIC values of Ag NPs against tested PATHOGENs were in the range of 3.12-6.25 mg/mL. While Listeria monocytogenes showed the MIC value of 6.25 mg/mL, Escherichia coli O157: H7, Salmonella typhimurium and Vibrio parahaemolyticus all showed the MIC values of 3.12 mg/ mL. However, all the PATHOGENs showed the same MBC value of 6.25 mg/mL. To obtain an efficient bactericidal activity against E. coli O157: H7 and S. typhimurium, the exposure time should be at least ca.6 hours., while this time was ca.5 hours for V. parahaemolyticus and ca.7 hours for L. monocytogenes. Conclusions: SILVER NANOPARTICLES showed great antibacterial effectiveness on four important foodborne PATHOGENs. Therefore, Ag NPs could be a good alternative for cleaning and DISINFECTION of equipment and surfaces in food-related environments.
