California Small Farm Food Safety Guidelines (CDFA)
Recommended practices from the CA Department of Food and Agriculture. A simple, easy to use checklist.

Small Farm Program Food Safety website (University of CA Davis)
A comprehensive list of Good Agricultural Practices audit checklists, fact sheets, resources and links.

Agricultural Water Testing Guidelines (National Sustainable Agriculture Coalition)
This site provides an explanation of the water testing regulations proposed in the Food Safety Modernization Act. (Not sure if your farm will be affected by the FSMA? This guide should help: Who is Affected? )

Water Testing Labs

We recommend calling the laboratory you choose to work with to receive specific instructions on sampling procedures and pick-up/delivery. Each laboratory should provide you with sampling containers, instructions and forms.

Remember that you should request a quantified generic E. coli test for irrigation water; wash water (potable water used in post-harvest handling) just needs a presence/absence test since it cannot have any E. coli in it. See our Water Testing Guidelines in our Producer Manual for more detailed guidance.
