Irrigation water quality can affect food safety and health and has been identified as a possible source of pathogens in produce linked to disease outbreaks. Many irrigation water sources are subject to contamination from various sources in surrounding watersheds. A systems-based, watershed scale analysis is therefore necessary to comprehensively identify both sources of contamination and the conditions in the environment that facilitated or created that contamination, termed here 'environmental antecedents'. Three nationwide disease outbreaks linked to produce in the United States (US) are used to illustrate this concept of a watershed scale assessment to investigate potential impacts of irrigation water quality on food safety.
灌溉水质量会影响食品安全和健康，并且已被认定为与疾病暴发相关的农产品中病原体的一个可能来源。许多灌溉水源都受到周边流域各种来源的污染。因此，有必要进行基于系统的流域尺度分析，以全面识别污染源以及促成或造成这种污染的环境条件，在此称之为“环境前因”。美国三起与农产品相关的全国性疾病暴发被用来阐释这种流域尺度评估的概念，以调查灌溉水质量对食品安全的潜在影响。
