Abstract Despite major efforts, food safety and food fraud issues continue to appear, showing the need for an improved risk anticipation to enhance consumer protection. To this end, we need a holistic view on the food production beyond the classical farm to fork principle and consider developments in- and outside the food chain. Commodity flows and prices are considered as relevant drivers for the emergence of food safety and fraud issues. To conveniently obtain information on these drivers and to monitor their changes, we developed a tool to analyze the volume, origin and price of foods imported to Germany, based on data of the German Foreign Trade Statistic. The ISAR-Tool (Import Screening for the Anticipation of Food Risks) facilitates a descriptive analysis of the import data of about 2400 different food items imported from 220 countries and an automated analysis of the data for a systematic detection of unexpected changes in import volumes and prices. For the automated approach, time series analyses using SARIMA and ETS models are applied and data points outside the model-based 99% prediction intervals are considered as potentially relevant changes. Monthly, more than 2000 of such changes are detected, leaving us with the challenging task of their evaluation for food safety and food fraud. To deal with the vast amount of results, of which the great majority cannot be linked to food safety or fraud issues, we implemented prioritization routines, and the 200 most critical results are considered for further expert evaluation. Despite remaining challenges in the performed evaluation process of the automated analysis, the described approach facilitates already at this stage an improved identification of food safety and food fraud hazards and the implementation of more targeted food safety controls, as shown in this paper. Our most prominent example of an identified food fraud and food safety risk was the detection of massive adulterations of hazelnut products with almonds and cashews, which were associated to the observed all-time high in hazelnut prices. Based on our findings, we conclude that the ISAR-Tool and the described analyses of commodity flows and prices can be important elements in the anticipation of risks and enable an enhanced consumer protection.

食品安全和欺诈问题的预测:ISAR - 监测食品价格和商品流动的新筛选工具

摘要 尽管做出了巨大努力,但食品安全和食品欺诈问题继续出现,表明需要改进风险预测以加强消费者保护。为此,我们需要超越经典的从农场到分叉原则的食品生产的整体观点,并考虑食物链内外的发展。商品流动和价格被视为食品安全和欺诈问题出现的相关驱动因素。为了方便地获取有关这些驱动因素的信息并监控它们的变化,我们开发了一个工具来分析进口到德国的食品的数量、来源和价格,基于德国对外贸易统计的数据。ISAR 工具(用于预测食品风险的进口筛选)有助于对从 220 个国家进口的大约 2400 种不同食品的进口数据进行描述性分析,并对数据进行自动分析,以系统地检测进口量和价格。对于自动化方法,应用了使用 SARIMA 和 ETS 模型的时间序列分析,并且基于模型的 99% 预测区间之外的数据点被视为潜在的相关变化。每月检测到 2000 多个此类变化,这让我们面临评估食品安全和食品欺诈的挑战性任务。为了处理大量结果,其中绝大多数与食品安全或欺诈问题无关,我们实施了优先排序程序,200 个最关键的结果被考虑进行进一步的专家评估。尽管在自动分析的执行评估过程中仍然存在挑战,但所描述的方法在此阶段已经促进了对食品安全和食品欺诈危害的改进识别以及更有针对性的食品安全控制的实施,如本文所示。我们发现的食品欺诈和食品安全风险最突出的例子是检测到大量掺假榛子产品与杏仁和腰果,这与观察到的榛子价格创历史新高有关。根据我们的调查结果,我们得出结论,ISAR 工具和所描述的商品流动和价格分析可以成为预测风险和加强消费者保护的重要因素。尽管在自动分析的执行评估过程中仍然存在挑战,但所描述的方法在此阶段已经促进了对食品安全和食品欺诈危害的改进识别以及更有针对性的食品安全控制的实施,如本文所示。我们发现的食品欺诈和食品安全风险最突出的例子是检测到大量掺假榛子产品与杏仁和腰果,这与观察到的榛子价格创历史新高有关。根据我们的调查结果,我们得出结论,ISAR 工具和所描述的商品流动和价格分析可以成为预测风险和加强消费者保护的重要因素。尽管在自动分析的执行评估过程中仍然存在挑战,但所描述的方法在此阶段已经促进了对食品安全和食品欺诈危害的改进识别以及更有针对性的食品安全控制的实施,如本文所示。我们发现的食品欺诈和食品安全风险最突出的例子是检测到大量掺假榛子产品与杏仁和腰果,这与观察到的榛子价格创历史新高有关。根据我们的调查结果,我们得出结论,ISAR 工具和所描述的商品流动和价格分析可以成为预测风险和加强消费者保护的重要因素。如本文所示,所描述的方法在现阶段已经促进了对食品安全和食品欺诈危害的改进识别以及更有针对性的食品安全控制措施的实施。我们发现的食品欺诈和食品安全风险最突出的例子是检测到大量掺假榛子产品与杏仁和腰果,这与观察到的榛子价格创历史新高有关。根据我们的调查结果,我们得出结论,ISAR 工具和所描述的商品流动和价格分析可以成为预测风险和加强消费者保护的重要因素。如本文所示,所描述的方法在现阶段已经促进了对食品安全和食品欺诈危害的改进识别以及更有针对性的食品安全控制措施的实施。我们发现的食品欺诈和食品安全风险最突出的例子是检测到大量掺假榛子产品与杏仁和腰果,这与观察到的榛子价格创历史新高有关。根据我们的调查结果,我们得出结论,ISAR 工具和所描述的商品流动和价格分析可以成为预测风险和加强消费者保护的重要因素。我们发现的食品欺诈和食品安全风险最突出的例子是检测到大量掺假榛子产品与杏仁和腰果,这与观察到的榛子价格创历史新高有关。根据我们的调查结果,我们得出结论,ISAR 工具和所描述的商品流动和价格分析可以成为预测风险和加强消费者保护的重要因素。我们发现的食品欺诈和食品安全风险最突出的例子是检测到大量掺假榛子产品与杏仁和腰果,这与观察到的榛子价格创历史新高有关。根据我们的调查结果,我们得出结论,ISAR 工具和所描述的商品流动和价格分析可以成为预测风险和加强消费者保护的重要因素。
