What Is a GAP Audit? A Simple Guide for Small Farms
Updated: Oct 6
GAP stands for Good Agricultural Practices. A GAP audit is a visit where a third party checks that your farm grows, harvests, and packs produce in a way that keeps it safe to eat. Many stores, schools, hospitals, and distributors now ask for one before they will buy from you.
Key takeaways
GAP is a buyer requirement, not a law. The buyer picks the scheme.
The audit checks water, soil amendments, workers, harvest and packing, and records.
If it is not written down, it did not happen. Records decide most audits.
A small farm can get ready in two to three months.
Kona Organic writes the plan, sets up the logs, and runs a practice audit first.
Who asks for a GAP audit
Grocery chains, school food programs, hospitals, and produce distributors. Each has a letter that names the audit scheme it accepts. The main ones are USDA GAP and GHP, USDA Harmonized GAP, PrimusGFS, and GLOBALG.A.P. Ask your buyer for the letter before you prepare, because the checklists differ.
What the audit looks at
Water. Where it comes from, whether it is tested, and how it touches the crop.
Soil amendments. How manure and compost are made, stored, aged, and applied, and how long before harvest.
Workers. Handwashing stations, toilets, illness policy, and training with sign in sheets.
Harvest and packing. Clean tools, clean bins, clean surfaces, and no glass or wood where it should not be.
Storage and transport. Temperature, cleanliness, and keeping produce off the ground.
Pests and animals. Keeping animals out of fields and packing areas, and what you do when you find signs.
Traceability. A lot number that follows the product from field to invoice.
Records. Proof that you do what your food safety plan says.
How to get ready
Start with a written food safety plan. Keep it short and true to how your farm really works. Then keep simple logs for water tests, cleaning, and worker training. Fix the physical items, cheapest first: a handwashing station, screens on the packing shed, pallets to keep bins off the floor. Walk your farm the way the audit will and score it honestly.
The most common mistake
Farms do the right things but have no records to show it. In an audit, if it is not written down, it did not happen. The second most common mistake is preparing for the wrong scheme.

Common questions
How much does a GAP audit cost?
The fee is set by the audit body and depends on the scheme and time on site. USDA has run cost share for food safety audits in recent years; check what is open when you start.
Do I need GAP if I am organic?
They are separate. Organic is about inputs and integrity. GAP is about food safety. Many buyers want both, and the records overlap.
