Food can become unsafe or contaminated at any point from production to distribution. The stakeholders and customers are also ready to pay more to ensure food safety and timely delivery. This shows the importance of visibility and operational efficiency in a food supply chain (FSC). Traditional supply chains are primarily manual and won't involve technologies. There will be issues like low traceability, efficiency, data tampering, etc. Implementing new and developing data acquiring technologies is a benefit to all the stakeholders, which helps them to make crucial decisions. It is necessary to trace the movement of products from origin to the consumers as supply chains that allow financial transactions between the entities lack trust and credibility. So it is evident that there is a need for a change in the traditional food supply chain by implementing technology systems.
The purpose of this work is to study how industry 4.0 technologies are used in the FSC for visibility and operational efficiency. A content analysis-based systematic literature review is conducted to find the research gaps. Based on the research gaps found, our research proposes to answer the following research questions:
RQ-1. How industry 4.0 technologies are impacting the food supply chain in terms of visibility and operational efficiency?

RQ-2. How technology costs can be shared among various entities of the food supply chain?

RQ-3. How the integration of two or more technologies can improve the FSC?
The proposed work can help the practitioners of FSC to redesign the existing supply chain. The number of food incidents can be reduced to a certain extent and also the coordination between the entities of the supply chain can be improved.
