Abstract
The massive rise of Big Data generated from smartphones, social media, Internet of Things (IoT), and multimedia, has produced an overwhelming flow of data in either structured or unstructured format. Big Data technologies are being developed and implemented in the food supply chain that gather and analyse these data. Such technologies demand new approaches in data collection, storage, processing and knowledge extraction. In this article, an overview of the recent developments in Big Data applications in food safety are presented. This review shows that the use of Big Data in food safety remains in its infancy but it is influencing the entire food supply chain. Big Data analysis is used to provide predictive insights in several steps in the food supply chain, support supply chain actors in taking real time decisions, and design the monitoring and sampling strategies. Lastly, the main research challenges that require research efforts are introduced.

This review showed that the main channels of obtaining data related to food safety are online databases, Internet, sensors, mobile phones, and social media
Summary
The term Big Data is used in various ways but always refers to large volumes of different types of data. The content of the selected publications is further investigated based on their content related to the various steps distinguished in a Big Data framework [1] These steps are i) data sources and collection, ii) infrastructure, and iii) data analysis. Other online food safety databases like United States (US) Import Refusal Report (IRR), Inspection Classification Database (ICD) and China State Administration for Market Regulation (SAMR) alerts have appeared (Table 2). Few researchers have tried to build a food safety inspection database using data mining based on the official released online food sampling records [9], and some commercial communities like foodmate updated the related food safety databases according to government publications.
