While human dietary exposure has received considerable attention, pesticide residues in animal feed represent a critical, underexplored pathway that can affect livestock health and crop production through the reuse of contaminated manure. This review examines these emerging risks by focusing on livestock health and the cascading effects on crops. Methods Following PRISMA 2020 guidelines, we systematically searched and synthesized literature addressing: (i) prevalence, types, and concentrations of pesticide residues in feed; (ii) toxicological effects on livestock; and (iii) environmental carryover potential via manure application to soils. Results Residues of major pesticide classes carbamates, organochlorines, organophosphates, and pyrethroids frequently enter feed through treated crops, pre-harvest desiccation, and environmental persistence. While EFSA concludes that typical exposure levels do not pose major acute risks to animal health, significant uncertainties remain regarding chronic low-dose exposures and synergistic effects of multi-residue mixtures on livestock physiology. Evidence on toxicological effects is drawn from a mixture of feed-specific, laboratory-animal, and human studies; the source of evidence for each finding is now explicitly identified throughout the Results (Section 3.3, Table 3). Discussion Experimental and field studies demonstrate that pesticide residues transfer from feed to manure and, subsequently, to soil when manure is used as fertilizer. This circular pathway creates secondary contamination, where residues are taken up by crops, causing phytotoxicity, reduced germination, and diminished performance. These findings underscore the need for strengthened regulatory frameworks addressing cumulative and carryover effects, alongside enhanced monitoring. From a One Health perspective, mitigating these risks requires broader adoption of sustainable practices, including Integrated Pest Management (IPM), safer pre-harvest protocols, and improved manure waste management to break the contamination cycle and protect animal, environmental, and human health.","引言 农药对于最大化作物产量和保障粮食安全至关重要，但人们对其在食物链中蓄积的担忧日益加剧。尽管人类膳食暴露已受到广泛关注，但动物饲料中的农药残留却是一条关键却研究不足的暴露途径，其可通过受污染粪肥的再利用影响畜禽健康与作物生产。本综述聚焦畜禽健康及其对作物的级联效应，审视这些新兴风险。方法 遵循PRISMA 2020指南，我们系统检索并综合了以下方面的文献：(i) 饲料中农药残留的流行率、类型及浓度；(ii) 对畜禽的毒理学效应；(iii) 通过粪肥施用至土壤的环境携带潜力。结果 主要农药类别——氨基甲酸酯类(carbamates)、有机氯类(organochlorines)、有机磷类(organophosphates)和拟除虫菊酯类(pyrethroids)——的残留常通过施用农药的作物、收获前干燥处理及环境持久性进入饲料。尽管欧洲食品安全局(EFSA)认为典型暴露水平不会对动物健康构成重大急性风险，但关于慢性低剂量暴露及多残留混合物对畜禽生理的协同效应仍存在显著不确定性。毒理学效应的证据来自饲料特异性研究、实验室动物研究和人体研究的混合来源；每项发现的证据来源现已在结果部分(第3.3节，表3)中明确标注。讨论 实验与田间研究表明，农药残留从饲料转移至粪肥，随后在粪肥用作肥料时进入土壤。这一循环途径造成二次污染，残留被作物吸收，导致植物毒性、发芽率降低和生长性能下降。这些发现凸显了加强监管框架以应对累积效应和携带效应的必要性，同时需强化监测。从“同一健康”(One Health)视角出发，降低这些风险需要更广泛地采用可持续实践，包括综合病虫害管理(IPM)、更安全的收获前操作规程以及改进粪肥废弃物管理，以打破污染循环，保护动物、环境和人类健康。",null,"Frontiers in Sustainable Food

摄\n\n该中心副主任彭焕介绍，根结线虫是潜藏于土壤中、破坏力极强的“隐形害虫”，可侵染3000余种植物，包括粮食、蔬菜等各类农作物。作物根系被根结线虫侵染取食后，会形成大小不一的根瘤根结，严重削弱作物根系吸收水肥的能力，造成植株生长衰弱、产量锐减。这一虫害也是影响新疆农作物稳产提质的重要原因。\n\n以往防治根结线虫，主要依靠化学类药剂。而长期施用化学药剂，不仅会让根结线虫逐渐产生抗药性，造成药效减退，还会给土壤带来负担。因此农业生产迫切需要高效环保的替代防控技术。RNA干扰技术是极具潜力的绿色防控手段，它能够精准“关闭”该害虫的关键基因，只针对靶标害虫起效，不会伤害其他生物。但该技术的活性物质在土壤中极易被分解，致使这项技术长期停留在实验室阶段，难以应用到大田生产中。\n\n此次科研团队突破技术应用瓶颈，从基因层面筛选出根结线虫的关键靶标基因MEKK-3，该基因只作用于根结线虫，对其他生物安全无害。团队搭建起该活性物质的规模化生产工艺，还采用星形聚阳离子纳米材料为有效成分打造一层“保护外壳”。相当于给药剂穿上防护外衣，使其埋入土壤后不易被分解。经过改良，根结线虫对药剂有效成分摄取量提升42.3%，基因沉默效果提高1.9倍，幼虫死亡率提升24.2%。\n\n温室试验结果显示：单纯施用活性药剂45天后，作物根部根结数量可减少56.6%；将纳米载体与药剂搭配使用，对根结线虫的防治效果提升至78.4%。科研人员探明其中机理：该关键基因被抑制后，根结线虫抵御外界胁迫、维持生存的生理通路遭到破坏，最终无法正常发育，导致死亡。\n\n彭焕介绍，这套新技术打通了从害虫靶点筛选、机理解析、规模化生产到温室试验验证的完整技术链条，证实MEKK-3基因可用于防控多种根结线虫，为研发安全广谱的新型RNA生物农药铺平了道路。他表示，未来该技术落地应用后，能够减少化学农药使用，守护耕地土壤健康，助力新疆农业绿色高质量发展，也为国内土传病虫害的绿色治理提供重要技术储备。","中国农业科学院西部农业研究中心\u002F新疆日报(2026-10)",87,{"impact":216,"substance":401,"depth":17,"authority":427,"freshness":151,"relevant":21,"comment":428},14,"国家级科研机构攻克RNA干扰大田应用瓶颈，数据详实、技术链条完整，具备行业示范价值，值得进入每日精选。",[430],{"name":424,"url":421},[432,433,434,26,435],"马铃薯","RNA干扰","根结线虫","生物农药",{"code":437,"slug":438,"name":439,"path":440,"parent_code":168},"A5","tubers-grains","薯类与杂粮","\u002Ftopic\u002Ffield-crops\u002Ftubers-grains",[442],{"code":39,"slug":40,"name":41,"path":42,"parent_code":43},{"status":45,"locked":14,"version":46,"method":47,"evidence":444},{"candidates":445,"agricultural_evidence":52},[446,450,455,461],{"code":39,"score":427,"supported":52,"title":447,"abstract":448,"tags":449},[26],[26],[433,435,26],{"code":437,"score":451,"supported":52,"title":452,"abstract":453,"tags":454},9,[432],[],[432],{"code":456,"score":204,"supported":52,"title":457,"abstract":458,"tags":460},"B7",[],[459],"温室",[],{"code":100,"score":21,"supported":14,"title":462,"abstract":463,"tags":464},[],[],[26],[466,467],"中国农科院西部中心
