Postharvest water includes any water that contacts fresh produce at or after harvest.  Postharvest water use may be a necessary part of fruit and vegetable production, but it is also a potential source of contamination. Understanding the risks associated with postharvest water use and how to minimize them are important for produce safety. The University of Tennessee in conjunction with Cornell University and the University of Minnesota created decision trees to help growers assess the risks on their farm, as well as food safety template language, record-keeping logs and sample SOPs that you can download and tailor to your needs.
