“…Although they are resource intensive, these assessments can provide valuable insight into outbreak causes and identify possible areas to target for prevention efforts. Environmental assessments conducted during multiple leafy green investigations have suggested a possible link between product contamination and STEC contamination of nearby soil or water caused by cattle or wild pigs (25,26), dairy farms (27), or CAFOs (28). These findings build on 2 studies conducted in leafy green growing regions in California; one identified a higher prevalence of STEC O157 in a watershed near cattle (29), and another detected STEC O157 in beef cattle feces, mostly during dates in the spring and fall when leafy greens are typically grown, although the number of samples that yielded STEC O157 was small (13).…”

“…Over the last two decades, the occurrence of multiple foodborne disease outbreaks linked to contamination of preharvest produce by wildlife (Cody et al, 1999;Jay et al, 2007;Kangas et al, 2008;Laidler et al, 2013;Kwan et al, 2014) or surface water (e.g., during irrigation; Gelting et al, 2011Gelting et al, , 2015Mody et al, 2011;Lundqvist et al, 2013;FDA, 2019) have highlighted the role of wildlife and surface water as on-farm sources of foodborne pathogens. As part of the traceback investigation during a 2006 Escherichia coli outbreak linked to bagged spinach, the outbreak strain was isolated from both feral pig feces and preharvest water from the implicated farm (Jay et al, 2007).…”

“…Human exposure may occur by direct means, such as the consumption of contaminated animal products and contact with infected animals or persons, or indirectly following dissemination along variable routes of transmission including contaminated drinking, recreational or irrigation water. Numerous waterborne or fresh produce-associated outbreaks where water likely served as a vector of transmission during crop production have been documented (Muniesa et al, 2006 ; Getling and Baloch, 2013 ). There are few reports on the prevalence and characteristics of STEC in surface waters used for home, recreational or agricultural uses despite potential risks to human health.…”

A hydrophobic grid membrane filtration—Shiga toxin immunoblot method was used to examine the prevalence of Shiga toxin-producing Escherichia coli (STEC) in four watersheds located in the Lower Mainland of British Columbia, Canada, a region characterized by rapid urbanization and intensive agricultural activity. STEC were recovered from 21.6, 23.2, 19.5, and 9.2% of surface water samples collected monthly from five sites in each watershed over a period of 1 year. Overall prevalence was subject to seasonal variation however, ranging between 13.3% during fall months and 34.3% during winter months. STEC were also recovered from 23.8% of sediment samples collected in one randomly selected site. One hundred distinct STEC isolates distributed among 29 definitive and 4 ambiguous or indeterminate serotypes were recovered from water and sediments, including isolates from Canadian “priority” serogroups O157 (3), O26 (4), O103 (5), and O111 (7). Forty seven isolates were further characterized by analysis of whole genome sequences to detect Shiga toxin gene (stx 1 and stx 2), intimin gene (eaeA) allelic variants and acquired virulence factors. These analyses collectively showed that surface waters from the region support highly diverse STEC populations that include strains with virulence factors commonly associated with human pathotypes. The present work served to characterize the microbiological hazard implied by STEC to support future assessments of risks to public health arising from non-agricultural and agricultural uses of surface water resources in the region.
