A sanitizer should be added to all postharvest water to reduce cross contamination and minimize potential transfer of pathogens to fresh produce. Sanitizers are critically important when using postharvest water in dump tanks, wash bins, or other batch water systems.

There are many sanitizers that can be used for postharvest water. Pick the sanitizer that is best for your operation and the produce you grow. Make sure to follow the label recommendations and only use sanitizer approved for your specific crop. Monitor sanitizer levels frequently to be sure they are effective at reducing cross contamination risks. If you are certified organic, check with your certifier to make sure you are using an approved sanitizer for your produce.
