Researchers from the University of Delaware and Biospection have developed a rapid testing method to identify foodborne pathogens on fresh produce within 3-6 hours, significantly improving current practices. This innovative technique employs multi-spectral imaging and deep UV sensing to detect physiological responses of plants infected by harmful pathogens like Salmonella and E. coli. By utilizing these technologies, the team aims to prevent the distribution of tainted produce, addressing public health concerns associated with foodborne illnesses. Current testing methods often result in delayed identification of contamination sources, leading to widespread recalls that can negatively affect consumer safety and industry operations.
The researchers’ system scans leaves for changes that indicate pathogen presence, enabling non-invasive, real-time analysis. As Biospection pushes forward with commercializing this technology, it could be integrated into vertical farms and crop drones, enhancing agricultural practices and food safety. The collaboration between academic and biotechnology sectors exemplifies the potential for scientific advancements to mitigate risks associated with microbial contamination in the food supply chain. Future research may focus on differentiating between various microbes based on plant responses, further enhancing diagnostic capabilities.
