Recent multistate outbreaks and recalls of fresh apples due to  Listeria monocytogenes  contamination have increased consumer concerns regarding fresh and processed apple safety. This study aimed to evaluate the antimicrobial efficacy of two sanitizers, mineral oxychloride (JC9450) and neutral electrolyzed water (NEW), for inactivation of  L. monocytogenes  on fresh apples. A 2-min treatment of 0.125% (v/v) JC9450 with 100 ppm free available chlorine (FAC) or NEW with 110 ppm FAC caused 0.9–1.2 log 10  CFU/apple reduction of  L. monocytogenes  on both Granny Smith and Fuji apples 24 h post-inoculation. Increasing JC9450 concentration to 0.25 and 0.50% significantly improved its bactericidal effect and reduced  L. monocytogenes  on Granny Smith apples by ~2.0 and 3.8 log 10  CFU/apple, respectively, after a contact time of 2 min. At a shorter contact time of 30 sec, the inactivation efficacy of chlorine and 0.25–0.50% JC9450 against  L. monocytogenes  on apples was significantly reduced compared with the respective 2-min wash. Furthermore, no  L. monocytogenes  was recovered in deionized water prepared antimicrobial wash solution or on non-inoculated apples post-NEW with 110 ppm FAC or 0.125–0.5% JC9450 washes, indicating their ability to prevent cross-contamination. In addition, a 2-min exposure to NEW with 110 ppm FAC and 0.50% JC9450 reduced apple native microbiota including total plate count by 0.14 and 0.65 log 10  CFU/apple, respectively, and yeast and mold counts by 0.55 and 1.63 log 10  CFU/apple, respectively. In summary,  L. monocytogenes  attached on apples was difficult to eliminate. JC9450 and NEW demonstrated a dose-dependent reduction in  L. monocytogenes  on apples and successfully prevented cross-contamination, indicating their application potential in post-harvest washes of apples.
