“…Multiple studies have investigated produce contamination pathways in the preharvest environment, including through biological soil amendments of animal origin (BSAAO), irrigation water, domestic and wild animals, and pesticide applications (Bell et al, 2015; Danyluk et al, 2008; Gorski et al, 2011; Gruszynski et al, 2014; Gu et al, 2018a, Gu et al, 2018b; Gu et al, 2019; Lopez‐Velasco, Tomas‐Callejas, Diribsa, Wei, & Suslow, 2013; Micallef et al, 2012; Stine, Song, Choi, & Gerba, 2011; Zheng et al, 2013). For instance, one study (Gu et al, 2018a, Gu et al, 2018b) observed the likelihood of Salmonella contamination on tomato leaves was significantly higher than on the tomato fruit in sampled fields. Another set of studies (Bolten et al, 2020; Soto, Chavez, Baez, Martinez, & Chaidez, 2007) found the adjacent leaves and debris could be the main cross‐contamination source during harvesting and post‐harvest handling; thus, inactivating or reducing Salmonella on tomato leaves may be a management practice to reduce contamination downstream.…”
