There is an increased concern that plants might be more important as a carrier for human enteric pathogens like E. coli O157:H7 and Salmonella enterica serovars than previously thought. This review summarizes the knowledge available on the ecology of E. coli O157:H7 and Salmonella enterica in the primary production chain of leafy green vegetables (in particular lettuce), including manure, manure-amended soil, and crop. Based on the available literature, suggestions are made for the control of these pathogens. The suggested approach of oligotrophication of agro-ecosystems fits in the wider approach to lower environmental emissions of nutrients from manure application and to enhance the suppression against plant pathogens.

初级蔬菜生产​​链中的大肠杆菌O157：H7和肠沙门氏菌的生态。

人们越来越担心植物比人类以前认为的更重要的是作为人类肠道病原体（如大肠杆菌O157：H7和肠炎沙门氏菌）的载体。这篇综述总结了在多叶绿色蔬菜（特别是生菜）的主要生产链中，包括粪便，粪便改良的土壤和农作物中大肠杆菌O157：H7和肠沙门氏菌的生态学知识。根据现有文献，提出了控制这些病原体的建议。建议的农业生态系统低营养化方法适合于更广泛的方法，以减少施肥过程中养分的环境排放，并增强对植物病原体的抑制作用。
