福建省生鲜食农产品中抗生素抗性基因污染及风险评估研究进展

    Research Progress on Contamination and Risk Assessment of Antibiotic Resistance Genes in Fresh Edible Agricultural Products in Fujian Province

    • 摘要: 抗生素抗性基因(antibiotic resistance genes,ARGs)作为新兴环境污染物,可在环境介质、动物宿主和微生物群落间持续迁移,并经食物链形成人群暴露,对食品安全和公共卫生构成潜在风险。福建省集约化水产和畜禽养殖并存,亚热带季风气候明显,山海相邻且水系连通,是开展食源性ARGs区域研究的典型区域。基于“One Health”理念,针对福建省主要生鲜食农产品中ARGs污染问题进行综述。(1)概述了典型农业生态系统对ARGs污染的驱动效应,从污染源头、传播路径、关键驱动机制等方面,阐述了其农业生态驱动背景。(2)归纳了福建省生鲜食农产品ARGs污染现状的研究进展,指出水产品和畜禽产品相关证据相对充分,但蔬菜尤其是生食叶菜,存在隐蔽暴露及内生定殖问题且缺乏系统阐释;同时,不同研究在样品类型等方面差异较大。(3)评述了ARGs风险评估方法学进展及其区域适用性局限,目前福建省相关研究面临区域本底数据不足、跨介质暴露链条衔接不清、ARGs活性与可移动性判定困难以及本地化风险参数缺失等问题。(4)探讨了ARGs污染的监测与防控方向,建议加强区域本底调查、全链条监测和分级风险评估,推动跨部门协同治理,为福建省食品安全保障和耐药传播防控提供参考依据。

       

      Abstract: As emerging environmental pollutants, antibiotic resistance genes (ARGs) can continuously migrate between environmental media, animal hosts and microbial communities, potentially leading to human exposure through the food chain and posing risks to food safety and public health. Fujian Province, characterized by the coexistence of intensive aquaculture and livestock production, a pronounced subtropical monsoon climate, and closely interconnected mountain - coast landscapes and river networks, serves as a representative region for investigating the foodborne ARGs at a regional scale. Based on the concept of “One Health”, the pollution of ARGs in main raw and fresh agricultural products in Fujian Province was reviewed. (1) The driving effects of typical agro-ecosystems on ARGs pollution were summarized, and the background of agro-ecological driving was expounded from the aspects of pollution source, propagation path and key driving mechanism. The research progress on the pollution status of ARGs in raw and fresh agricultural products in Fujian Province was summarized. It was pointed out that the relevant evidence of aquatic products and livestock and poultry products was relatively sufficient. However, the vegetables, especially raw-eaten leafy vegetables, had hidden exposure and endogenous colonization problems and lacked systematic explanation. (3) The progress of ARGs risk assessment methodology and its regional applicability limitations were reviewed. At present, the related research in Fujian Province was faced with problems such as insufficient regional background data, unclear connection of cross-media exposure chains, difficulty in determining ARGs activity and mobility, and lack of localized risk parameters. (4) The direction of monitoring and prevention and control of ARGs pollution was discussed, and it was suggested to strengthen the regional background investigation, whole chain monitoring and hierarchical risk assessment, and promote the cross-sectoral collaborative governance, thus to provide reference for the food safety guarantee and the prevention and control of drug resistance transmission in Fujian Province.
