Produce washing remains a key intervention despite only achieving a 1-2 log reduction and potential for cross-contamination. Our objectives were to establish the wash water parameters that impact on the efficacy of washing leafy greens within commercial settings. Sampling visits were performed at two commercial fresh-cut processors with the microbial loading of raw material, pre-wash and post-wash product being determined. At the same time water quality parameters (bacterial loading, turbidity, conductivity, and temperature) were measured. Microbial community populations were evaluated using...
