Use of mathematic models to describe the microbial inactivation on baby carrots by gaseous chlorine dioxide

Abstract This study investigated the behavior of Shiga toxin-producing Escherichia coli (STEC), Salmonella, and potential surrogate bacteria (nonpathogenic E. coli and attenuated Salmonella) subjected to gaseous chlorine dioxide (ClO2). Pathogenic and surrogate bacteria were separately inoculated on carrots (400 g) and treated with gaseous ClO2 at low (1 g) or high (6 g) ClO2 precursor inputs for 0, 15, 30, and 60 min in a 35 L enclosed chamber. Overall, significant log reductions (P
