“…Potential routes by which S. enterica and enterovirulent E. coli colonize edible plant parts in the field and under greenhouse conditions have been investigated (Fletcher et al, 2013;Islam et al, 2004;Moyne et al, 2011;Park et al, 2012). Pre-harvest, microbiological quality of fresh produce is affected by the presence of native epiphytic microbiota (including phytopathogens), the types and levels of irrigation, and the use of soil amendments (Allard et al, 2014;Brandl, 2006Brandl, , 2008Brandl and Amundson, 2008;Franz and van Bruggen, 2008;Gu et al, 2013;GutierrezRodriguez et al, 2012;Moyne et al, 2011;Park et al, 2012;PozaCarrion et al, 2013). However, relatively little remains known about the impact of crop production practices on post-harvest susceptibility of raw fruits and vegetables to human pathogens.…”
