Supply Chain Integrity System for Ensuring the Safety and Quality of Food and Medicine

Abstract

Supply chain integrity is essential to ensure the safety and quality of food and medicine. It 
involves maintaining proper standards during production, storage, transportation, and distribution. A 
strong supply chain helps prevent contamination, spoilage, and the entry of counterfeit products. 
Technologies such as tracking systems, barcodes, QR codes, and temperature monitoring play an important 
role in maintaining transparency and control, and regulatory guidelines and regular inspections also 
support safety at every stage. When supply chains are well managed, consumers receive safe and effective 
products. The proposed system is a digital Supply Chain Integrity System for Food Safety and Medicine 
that provides a centralised platform where manufacturers, distributors, transporters, inspectors, retailers, 
and consumers can interact and access real-time product information. The system integrates product 
registration, shipment tracking, temperature monitoring, counterfeit detection, inspection reporting, and 
QR-code verification within one unified application, together with a dashboard that aggregates analytics 
on products, shipments, inspections, and temperature logs. The prototype is implemented using Python, 
Streamlit, and SQLite, with Plotly-based dashboard visualisations and a QR-code module for product 
verification, and was validated through functional test cases covering product registration, validation, QR
code generation, shipment tracking, and related modules, all of which passed. Ensuring integrity builds 
trust, protects public health, and reduces risks related to unsafe or fake food and medicines in the market.
