UNASSIGNED: The objective of this study was to evaluate the antimicrobial effect of chlorine dioxide (ClO2) gas and aerosolized sanitizer, when applied alone or in combination, on the survival of @entity526 O157:H7, @entity2491 , and @entity5125 inoculated onto @entity2772 leaves and @entity523 surfaces. @entity2772 leaves and tomatoes were inoculated with a cocktail of three strains each of the three foodborne pathogens. ClO2 gas (5 or 10ppmv) and aerosolized peracetic acid (PAA) (80ppm) were applied alone or in combination for 20min. Exposure to 10ppmv of ClO2 gas for 20min resulted in 3.4, 3.3, and 3.4 log reductions of @entity526 O157:H7, @entity2491 , and @entity5125 on @entity2772 leaves, respectively. Treatment with 80ppm of aerosolized PAA for 20min caused 2.3, 1.9, and 0.8 log reductions of @entity526 O157:H7, @entity2491 , and @entity5125 , respectively. Combined treatment of ClO2 gas (10ppmv) and aerosolized PAA (80ppm) for 20min caused 5.4, 5.1, and 4.1 log reductions of @entity526 O157:H7, @entity2491 , and @entity5125 , respectively. @entity526 O157:H7, @entity2491 , and @entity5125 on tomatoes experienced similar reduction patterns to those on @entity2772 leaves. As treatment time increased, most combinations of ClO2 gas and aerosolized PAA showed additive effects in the inactivation of the three pathogens. Combined treatment of ClO2 gas and aerosolized PAA produced injured cells of three pathogens on @entity2772 leaves while generally did not produce injured cells of these pathogens on tomatoes. Combined treatment of ClO2 gas (10ppmv) and aerosolized PAA (80ppm) did not significantly (p>0.05) affect the color and texture of samples during 7days of storage.

Combination treatment of chlorine dioxide gas and aerosolized sanitizer for inactivating foodborne pathogens on XXXX leaves and tomatoes.
