The industry will receive an example methodology that shows how to validate the control of cross-contamination in recirculated high-pressure washers and fungicide flooders during citrus packing operations. Subsequently, the report will be published in a scientific journal as an evidence to meet audit and/or regulatory requirements. The approach reported by this study has the potential to be used in food safety training for implementing control measures in packing facilities. The project also builds a local, California-based research team to help strengthening California citrus industry’s knowledge and capacity in addressing emerging food safety challenges.
