Researchers at Hyderabad’s BITS Pilani campus have developed a portable sensing platform capable of detecting pesticide residues in food and water samples outside conventional laboratory settings, a development that could strengthen food safety monitoring across agricultural supply chains and urban markets.
The handheld device combines two independent testing methods within a single platform, allowing users to identify pesticide contamination and verify results simultaneously. Researchers say the technology has been designed to address a major challenge in food safety systems: the limited availability of affordable and rapid testing tools at the point of use. Food safety experts note that pesticide contamination remains a persistent concern in many agricultural economies. While advanced laboratory techniques provide highly accurate analysis, their cost, technical complexity and dependence on specialised infrastructure often restrict large-scale field deployment. The newly developed platform seeks to bridge this gap by offering a portable alternative that can be used in farms, food distribution networks, wholesale markets and local inspection centres. The system integrates optical sensing technologies, digital electronics and smartphone connectivity, enabling real-time analysis without requiring access to centralised laboratories.
Researchers report that the device demonstrated high levels of accuracy while identifying commonly used pesticide compounds across multiple sample types, including agricultural produce and water sources. The technology was also tested against established laboratory methods and showed strong agreement with conventional analytical results. A key feature of the platform is its ability to differentiate between various pesticide categories through data analytics and machine-learning tools. Experts say this capability is particularly valuable because safety thresholds and regulatory limits differ significantly between chemical compounds. The Food Safety Technology innovation arrives at a time when governments and regulatory agencies are placing greater emphasis on traceability, quality assurance and consumer protection within food systems. Rapid testing tools can help identify contamination risks earlier in the supply chain, reducing potential health impacts and improving compliance with food safety standards.
Affordability may also be a significant advantage. Researchers estimate that the device can be manufactured at a relatively low cost compared with traditional laboratory equipment, creating opportunities for wider deployment in resource-constrained environments. Urban sustainability specialists highlight the broader implications of such technologies. Reliable food quality monitoring supports public health, strengthens consumer confidence and contributes to more resilient agricultural and food distribution systems. As India continues to modernise its food safety infrastructure, innovations that combine portability, affordability and analytical accuracy are expected to play a growing role in supporting both producers and regulators. Researchers believe the platform could eventually help expand access to quality testing while improving monitoring capabilities across diverse geographic regions.
