Produce Safety in Hydroponic and Aquaponic Operations: Harvest and Postharvest Handling

Harvest and postharvest handling practices in hydroponic and aquaponic operations are generally similar to those used in field agriculture. A key difference is that in these operations production water (water used in the growing of a crop) can be in close proximity to the crop during harvesting. Postharvest water (water that contacts produce or food contact surfaces during or after harvest) may or may not be used in these operations since they are soilless and often produce is not washed. The objective of this factsheet is to focus on practices that reduce the risk for cross-contamination between water, tools and equipment, and people during harvest and postharvest activities.
