Sampling plans for food testing adopted in official documents published by countries and international organizations are reviewed. The aim of this review was to summarize the information contained in various documents and to identify the risk level for producers and consumers in the international food trade. Sampling policies described in several official documents, such as the directives of the European Commission and the Code of Federal Regulations of the United States, are introduced. The relation between lot size and sample size during bulk sampling was summarized and fitted to several functions, which showed that sample size is roughly proportional to the square root of the lot size.
