中文摘要:
      土壤健康,特别是农业土壤的健康,与食品安全密切相关。然而,目前在土壤中已检出了大肠杆菌、肠沙门氏菌、单核增生李斯特氏菌等食源性致病细菌。某些食源性致病细菌能适应土壤中生物与非生物环境并可长期存活,其毒力基因与抗生素抗性基因可能会通过食物链传播,从而给土壤环境生物安全与消费者健康带来风险。本文综述了土壤中食源性致病细菌的主要来源及其生存策略,并介绍了源头治理和原位修复的方法。在此基础上,对土壤中食源性致病细菌治理的技术策略进行了展望,并从改善土壤化学环境和物理环境、切断传播途径、生物防治等方面讨论了未来研究重点关注的方向,以期为保障土壤健康和食品安全提供新思路。
英文摘要:
      Soil health, particularly agricultural soil health, is closely related to food safety. However, several food-borne bacterial pathogens, such as Escherichia coli, Salmonella enterica, and Listeria monocytogenes, have been detected in soil. Some bacterial pathogens have adapted to various biotic and abiotic environments to improve their survival in soil. Their virulence genes and antibiotic resistance genes may be transmitted via the food supply system, creating risks for both soil environmental biosafety and consumer health. In this review, we focused on the sources of food-borne bacterial pathogens in soil, factors that influence their survival, and decontamination technologies including source disinfestation and in situ remediation. Future studies are needed to evaluate pathogen decontamination technologies and strategies. Research directions are discussed from the perspectives of improving the soil ′ s chemical and physical environment, transmission blocking, and biocontrol to promote the development of methods for maintaining soil health and protecting food safety.
