Shrimp are a globally traded aquaculture commodity that accounts for a large proportion of the monetary value of aquaculture. There are concerns among consumers about seafood labeling fraud and environmental sustainability. Therefore, the geographic origin of shrimp from retail stores was investigated with trace element profiling. 94 shrimp samples were collected from grocery stores across the USA, UK, and EU in 70 different grocery stores. The results of 24 elements are reported. Shrimp samples were from Thailand, India, Vietnam, Indonesia, and Ecuador were shown to have 15 elements that were statistically different across labeled country of origin, with Ecuador having unique post hoc group membership in 5 of the elements. Based on a classification procedure, shrimp were classified to labeled country of origin with an overall accuracy of 71.2%. Overall, the results suggest that elemental profiling could be a traceability tool for classifying samples of shrimp from retail stores.
虾是一种全球交易的水产养殖商品，在水产养殖货币价值中占很大比例。消费者担心海鲜标签欺诈和环境可持续性问题。因此，通过微量元素分析对零售商店中虾的地理来源进行了调查。从美国、英国和欧盟的70家不同杂货店收集了94份虾样本。报告了24种元素的结果。来自泰国、印度、越南、印度尼西亚和厄瓜多尔的虾样本显示，有15种元素在标注的原产国之间存在统计学差异，其中厄瓜多尔在5种元素中具有独特的事后分组归属。基于一种分类程序，虾被分类到标注的原产国，总体准确率为71.2%。总体而言，结果表明元素分析可能是一种用于对零售商店中虾样本进行分类的可追溯工具。
