Plastic pollution arising from food systems is driving policies for reduction, removal, reuse and recycling, but literature on plastic uses and outcomes across subsectors is fragmented. We use a systematic scoping review to describe the extent, range and nature of published evidence since 2000 on seven major plastic types used at any point within food systems and their quantifiable effects on the environment, food security and human health. Although the majority of publications focus on agricultural production, relatively fewer consider retail, household and food waste disposal plastics. Gaps in the research include evidence from low- and middle-income countries, health or food security and/or economic outcomes generated from human population studies-and the subsequent environmental and human health effects. A greater understanding of this disparate evidence landscape is essential to formulate coherent research strategies to inform potential policy actions and assess trade-offs across economic and environmental targets, human health and food security.
食品系统产生的塑料污染正在推动减少、清除、再利用和回收利用的政策，但关于塑料在各子部门的使用情况和结果的文献却很零散。我们进行了一项系统的范围审查，以描述自2000年以来已发表的关于食品系统内任何环节使用的七种主要塑料类型的证据的范围、广度和性质，以及它们对环境、粮食安全和人类健康的可量化影响。虽然大多数出版物关注农业生产，但相对较少考虑零售、家庭和食品废物处理中的塑料。研究差距包括来自低收入和中等收入国家的证据、人口研究产生的健康或粮食安全及/或经济结果，以及随后的环境和人类健康影响。更深入地了解这一分散的证据格局对于制定连贯的研究战略至关重要，这些战略可为潜在的政策行动提供信息，并评估经济和环境目标、人类健康和粮食安全之间的权衡。
