Rechargeable antimicrobial and antifouling plastics for improved cleaning and sanitation of plastic bins and totes

Sanitation of reusable plastic containers is a significant challenge that increases the risk of cross- contamination of fresh produce with both pathogenic and spoilage microbes. This proposed research is aimed at addressing this unmet need by developing novel rechargeable antimicrobial and antifouling plastic materials and evaluating their potential to prevent contamination of RPC surfaces with Listeria and formation of Listeria biofilms. The specific goals of the proposed research are: (a) eliminate Listeria contamination of RPC food contact surfaces using novel rechargeable antimicrobial plastic surface from contaminated water, produce or other residues; (b) significantly reduce/eliminate biofouling and biofilm formation and (c) demonstrate translation of this material to provide continuous sanitation of RPCs in an industrial setting. To achieve these goals, this project brings together an interdisciplinary team of polymer chemist, food safety engineer and food microbiologist. In summary, this proposal addresses an unmet need to improve sanitation of reusable plastic containers in fresh produce industry and has a significant potential to develop a novel solution that can aid in improving safety of fresh produce across the entire chain including growers, processors, shippers and retailers.
