Résumé
This project aims to improve food safety of hydroponically grown fresh produce using recycled wastewater by developing a novel photochemical water treatment for pathogen inactivation and establishing a quantitative pathogen risk assessment framework. We will employ efficient photo-oxidants under ultraviolet light irradiation to inactivate pathogens in recycled wastewater including norovirus, and develop a pathogen transport model to quantitatively assess microbial risk and food safety grown in hydroponics systems. Water reuse in hydroponics systems offers a sustainable and new approach for urban farming but poses new challenges for food safety. Photochemical water treatment is an efficient water reuse technology advantageous in agriculture, and the proposed pathogen-plant transport modeling framework is a unique tool to minimize food safety risks. Combining these engineering and computational techniques will improve food safety. This project involves a combination of environmental, microbial and agricultural engineers at one University of California Extension Center and two Land Grant institutions in arid Southern California - the University of California, Riverside (UCR) and University of California, Irvine (UCI) - both being Hispanic-serving degree-granting institutions. This project will increase the overall potential of long-range improvement in and sustainability of U.S. agriculture and food systems.Food and agricultural systems are under the constraints of a growing population and pressure on water resources, challenges of climate variability and change. ?

Objectifs
This project aims to improve food safety of hydroponically grown fresh produce using recycled wastewater by developing a novel photochemical water treatment for pathogen inactivation and establishing a quantitative pathogen risk assessment framework. Water reuse in hydroponics systems offers a sustainable and new approach for urban farming but poses new challenges for food safety. Persulfate-based photochemical water treatment is an efficient water reuse technology advantageous in agriculture, and the proposed pathogen-plant transport modeling framework is a unique tool to minimize food safety risks. Combining these engineering and computational techniques will improve food safety.This projectwill enhance the PD’s knowledge in pathogen control and microbial risk assessment, and it will generate exciting ideas on food safety improvement. The project directly addresses the goals of Foundational and Applied Science Program Area Priorities relating to food safety, nutrition and health, and natural resources and environment.
