摘要

洪水是影响社会、粮食安全和环境的最常见的自然灾害。众所周知,在新鲜园艺农产品的初级生产和加工过程中,洪水是影响食品安全的生物、化学和物理危害的载体。牲畜、工业、住宅和污水处理区流入水道的径流及其溢流会污染农业水源、生产场地和收获后加工设施。洪水的短期和最显著影响是粪便指标(如大肠杆菌)数量的短暂增加,以及在农产品、水、土壤和加工设施中检测到环境病原体(如单核增生李斯特菌和沙门氏菌),导致微生物污染造成大量粮食损失,并可能导致农产品消费者中食源性疾病的增加。然而,由于微生物病原体在土壤、水源和加工环境中的生存和持续存在,经常性洪水的长期影响要严重得多,破坏性也大得多。本文重点介绍了洪水如何加剧新鲜农产品初级生产和加工中的微生物食品安全风险,并简要介绍了管理策略。

Flooding adversely affects fresh produce safety
Flooding is the most recurring and common natural disaster affecting society, food security and the environment. Floodwater is known to be a carrier of biological, chemical and physical hazards affecting food safety during primary production and processing of fresh horticultural produce. Runoff from livestock, industrial, residential and sewage treatment areas into waterways and their overflow can contaminate agricultural water sources, production fields and post-harvest processing facilities. A transient increase in the population of faecal indicators such as Escherichia coli and the detection of environmental pathogens such as Listeria monocytogenes and Salmonella in produce, water, soil and processing facility are the short-term and most notable impacts of flooding, leading to a significant amount of food losses due to microbial contamination and potentially a rise in the foodborne illnesses among produce consumers. However, the long-term impacts of recurring flooding are far more severe and damaging due to the survival and persistence of microbial pathogens in soils, water sources and processing environments. This article focuses on how flooding can exacerbate the microbial food safety risks in the primary production and processing of fresh produce and briefly describes the management strategies.
