The frequency of plastic debris entering agricultural land is likely going to increase due increased discharge into surface waters and more frequent flood events. Microbial biofilm on the surfaces pollution (known as 'plastisphere') in freshwater environments often includes human pathogenic bacteria capable causing disease. Pathogens have been detected plastics environments, but it yet be determined whether can also transport pathogens fields during flooding. Therefore, this study quantified presence viable at five along two rivers. All visible debris, including sewage-associated waste, were collected a perpendicular 100 m transect from riparian zone each field. pieces screened for target (Escherichia coli, intestinal enterococci, Salmonella spp., Campylobacter Klebsiella spp.) using selective media, positively identified colonies subsequently tested antimicrobial resistance. In all fields, there higher volumes areas closer river, with 75% ± 24% within 30 riverbank. Overall, 49% was colonised by phenotypically positive least one or bacteria, resistance commonly prescribed antibiotics among several these bacteria. contaminated fluvial floodwater could pose an unquantified risk introducing potentially harmful systems ultimately food chain.
