"Susceptibility of pESI positive Salmonella to treatment with biocide chemicals approved for use in poultry processing as compared to Salmonella without the pESI plasmid": citation to be added upon publication.

Abstract: Salmonella is a common cause of human foodborne illness which is frequently associated with consumption of contaminated or undercooked poultry meat. Serotype Infantis is among the most common serotypes isolated from poultry products. Isolates of serotype Infantis carrying the pESI plasmid have been shown to exhibit oxidizer tolerance. Therefore, sixteen strains of Salmonella with and without pESI carriage were investigated for susceptibility to biocide chemical processing aids approved for use in U.S. poultry processing. All strains tested were susceptible to all concentrations of peracetic acid, cetylpiridinium chloride, and sodium hypochlorite when applied for 90 minutes. When cetylpiridinium chloride, calcium hypochlorite, and sodium hypochlorite were applied for 15 seconds to simulate spray time, strains responded similarly to each other. However, strains responded variably to exposure to PAA. The variation was not statistically significant and appears unrelated to pESI carriage. Results highlight the necessity of testing biocide susceptibility in the presence of organic material and in relevant in situ applications.
