  Despite using ozone (O3) as an attractive alternative disinfectant for more than a century, little is known about the killing capacity of O3 against Salmonella contaminated different surfaces in dairy operations. Accordingly, our objective was to characterize the killing capacity of aqueous and gaseous O3 at different operational conditions on Salmonella Typhimurium and Salmonella Choleraesuis (aSTC) contaminated plastic, metal, nylon, rubber, and wood surfaces. In a crossover design, 14 strips of each material were randomly assigned between 3 groups, treatment (n=6), positive-control (n=6), and negative-control (n=2). The strips were loaded with aSTC (107-108) and exposed to aqueous O3 of 2, 4, and 9 ppm for 4 minutes, and gaseous O3 of 1 and 9 ppm for 30, 60, and 120 minutes. Plastic and metal surfaces were most effectively decontaminated, an aqueous O3 of 4 ppm reduced aSTC by 6.7 .. View More»
