The quality and use of agricultural water is a top concern for members of the produce industry. This page provides resources regarding risk assessment, testing, and much more. Related United Fresh resources can be found on our Harmonized Standard webpage.
Harmonized Ag Water Risk Assessment
United Fresh’s Food Safety Council and Harmonized Calibration Committee agreed that the industry would benefit from a document that a grower can use to guide their thought process through the assessment of their agricultural water risk. The following document is a compilation of existing resources and approaches developed by the volunteer workgroup.
- Assessing Risk of Pre-Harvest Agricultural Water
- Example Documentation for Ag Water Risk Assessment
- 3.2.2. Interpretation Summary – Considerations for the postharvest use of surface water
FDA Ag Water Resources
Equivalent Testing Methodologies for Agricultural Water
FDA announced their intent to re-examine subpart E to contemplate opportunities to simplify the rule. In the meantime, FDA has extended the compliance date for the ag water testing requirement by 2 years (this subpart of the rule already had extra time for compliance; this would be further extended by 2 years). FDA has also published additional test methods that can be used to assess generic E. coli in agricultural water. That FDA resource can be found here.
FDA has determined that the following methods are “scientifically valid” and “at least equivalent to the method of analysis in § 112.151(a) in accuracy, precision, and sensitivity. For more information and to see the equivalent methods, visit the FDA site.

The University of Vermont created a map of US Water Testing Laboratories. That map can be found on the UVM website here.
Ag Water Webinar Recording Available
FSMA-related Agricultural Water Testing Requirements in the Produce Safety Rule have been a top concern for the fresh produce industry.
Now that FDA has made several announcements related to the Ag water testing provision, including delaying implementation of that part of the rule and identifying several test methods that are “scientifically valid” and “at least equivalent to the method of analysis in § 112.151 a, please join Dr. Jennifer McEntire, United Fresh Senior VP of Food Safety and Technology for an insiders perspective. She’ll discuss FDA’s ag water extension timeline, the new and equivalent test methods and what this means for your operation. View a recording of the webinar here.
The Western Center for Food Safety contains links to tools (excel spreadsheets, app, online calculator for untreated surface water and untreated ground water) that can help you calculate the GM and STV and to determine if your water meets the criteria for appropriate application to produce before harvest.
