霉菌毒素是天然產生的有毒化合物，常見于污染動物飼料。雖然霉菌毒素對牲畜健康的影響已有廣泛研究，但量化其經濟與環境綜合影響的系統性研究仍顯不足。本研究通過整合薈萃分析與生命周期評價（LCA）方法，評估霉菌毒素污染飼料對肉雞生產造成的潛在經濟與環境后果——這一全球性問題。以歐洲比荷盧地區典型肉雞養殖場為模型，我們發現當禽類攝入兩種及以上受歐盟監管的霉菌毒素（脫氧雪腐鐮刀菌烯醇、玉米赤霉烯酮、伏馬毒素B1、赭曲霉毒素A及T-2/HT-2毒素）污染的飼料時，飼料利用效率顯著降低10.8%（p＜0.05）。對于10萬只規模的養殖場，此類損失意味著每年需額外投入400噸飼料，成本增加約20萬歐元。為評估飼料霉菌污染的環境影響，研究分析了包括全球變暖潛勢、資源消耗、生態毒性、富營養化、酸化、臭氧層耗竭及電離輻射等19類環境足跡指標。LCA結果表明所有環境影響類別均呈加劇趨勢：因飼料增產及磷氮排泄增加，碳上升8.5%，全球變暖潛勢、酸化與富營養化影響顯著增強。本研究證實，解決小麥、玉米和大豆等飼料作物的霉菌毒素污染問題，對實現全球可持續、低碳且盈利的家禽養殖具有重要意義。

Abstract

Mycotoxins are naturally occurring toxic compounds that frequently contaminate animal feeds. While the effects of mycotoxins on livestock health are extensively studied, comprehensive research quantifying their combined economic and environmental impacts remains limited. This study addresses the research gap by integrating meta-analysis and life cycle assessment (LCA) to evaluate the potential economic and environmental consequences of broiler production using mycotoxin-contaminated feeds, a widespread issue globally. Using a representative broiler farm in the Benelux region of Europe as a model, we observed a 10.8 % reduction in feed utilization efficiency (p < 0.05) when birds consumed feeds contaminated with two or more EU-regulated mycotoxins (deoxynivalenol, zearalenone, fumonisin B1, ochratoxin A, and T-2/HT-2 toxin). For 100,000 birds, this inefficiency translated to 400 t of additional feed annually, costing around €200,000. In order to evaluate the environmental impacts of feed mycotoxin contamination, a comprehensive set of 19 environmental footprint categories was analyzed, including global warming potential, resource use, ecotoxicity, eutrophication, acidification, ozone depletion, and ionizing radiation. The LCA results revealed increased impacts across all categories, with an 8.5 % rise in carbon footprint and significant increases in global warming potential, acidification, and eutrophication due to heightened feed production as well as phosphorus and nitrogen excretion. This study shows that addressing mycotoxin contamination in feed crops such as wheat, maize, and soybean is important for achieving sustainable, low-carbon, and profitable poultry production globally.

Highlights

This study combines meta-analysis and LCA to assess mycotoxins' economic and environmental impacts in poultry.

Mycotoxin contamination reduces feed efficiency, raising costs and resource use.

LCA shows an 8.5 % rise in broiler production's carbon footprint due to feed inefficiencies。

Mycotoxins increase nitrogen and phosphorus excretion, exacerbating eutrophication and acidification.

Findings highlight the need to re-evaluate current mycotoxin limits to reduce economic and environmental burdens in poultry production.
