The article aims to identify stage of the food supply chain (FSC) has the greatest food loss and waste (FLW), the factors that influence and economic, social and environmental impacts in Latin America countries. We carried out a scoping review of observational studies, case reports and interventional studies in January 2023. Searches were performed in scientific databases and hand-searching of reference lists. Data on the included studies were summarized with narrative synthesis. In total 16 articles met the inclusion criteria. The greatest FLW occur in the early and middle stages of the FSC, mainly during storage. The main causes were connected to financial, managerial and operational limitations related in harvesting techniques, storage and cooling facilities, infrastructure and marketing systems. Food waste (FW) is also a result of lack of appropriate storage facilities and efficient transport systems, market fluctuations and systems. Only one study presented results on the environmental impact of FW. There is a higher occurrence of food loss, characterized by decrease in the quantity and quality of food in the first three stages of FSC.
本文旨在确定食品供应链（FSC）的哪个阶段产生的食物损失和浪费（FLW）最大，以及影响拉丁美洲国家食物损失和浪费的因素，包括经济、社会和环境影响。我们于 2023 年 1 月对观察性研究、病例报告和干预性研究进行了范围综述。在科学数据库中进行了检索，并对参考文献进行了手工检索。对纳入研究的数据进行了叙述性综合总结。共有 16 篇文章符合纳入标准。FSC 的早期和中期阶段发生的食物损失和浪费最大，主要发生在储存阶段。主要原因与收获技术、储存和冷却设施、基础设施和营销系统相关的财务、管理和运营限制有关。食品浪费（FW）也是由于缺乏适当的储存设施和高效的运输系统、市场波动和系统造成的。只有一项研究报告了 FW 对环境影响的结果。在 FSC 的前三个阶段，食物损失的发生率更高，其特征是食物数量和质量下降。
