Plants may harbor the human pathogen Salmonella enterica. Interactions between S. enterica and different plant species have been studied in individual reports. However, disparities arising from distinct experimental conditions render a meaningful comparison very difficult.

Agricultural environments are becoming increasingly contaminated with plastic pollution. Plastics in the environment can also provide a unique habitat for microbial biofilm, termed 'plastisphere', which support persistence of human pathogens such as Salmonella. Human enteric Salmonella enterica serovar Typhimurium enter agricultural via flooding or from irrigation water. Using soil mesocosms we quantified ability S. to persist on microplastic beads two agriculturally relevant soils, under ambient and repeat flood scenarios. persisted plastisphere 35 days both podzol loamy soils; while during multiple events was able survive up 21 days. could dissociate migrate through leachate, importantly colonise new particles soil, suggesting that pollution soils aid facilitate further dissemination within environment. The potential increased survival food production due contamination poses significant public health risk, particularly potato root vegetable systems where there is direct contact crops.
