The food safety and sustainability standards farms face

An Ohio grower selling wholesale cucumbers to a Columbus distributor may be asked for a food safety audit certificate before the first pallet leaves the farm. The same grower selling the same cucumbers at a Saturday market may never be asked for one at all. The standards that sit behind those two requests are not a single rulebook. They are a stack of programmes, some federal and voluntary, some state and mandatory, and knowing which one a buyer means saves a season of confusion.

The details cited in this entry were checked on USDA GAP audit page.

This is a map of that stack: the USDA audit programmes a farm can sign up for, the state division that enforces the produce safety rule in Ohio, and the practical question of who actually walks onto the farm to check.

What a GAP audit is actually verifying

Good Agricultural Practices audits are voluntary. That word matters, because it means no inspector arrives unannounced to conduct one. A grower books it, usually because a buyer asked. What the audit verifies is that fruits and vegetables are produced, packed, handled and stored in ways that minimise the risk of microbial food safety hazards.

The benchmark behind the checklist is the U.S. Food and Drug Administration's guide to minimising microbial food safety hazards for fresh fruits and vegetables, together with practices the industry itself recognises. An auditor is not testing your tomatoes. The auditor is reading your water records, your worker training log, your cooler temperatures and your sanitation schedule, then walking the fields and packing shed to see whether those records describe what is actually happening.

The scale is worth holding in mind. In 2021 the USDA carried out GAP audits in 50 states, Puerto Rico and Canada, covering more than 90 commodities. A vegetable farm in Ohio is one line in a very large ledger.

The audit is not one audit

USDA GAP audit services are a family, not a single product. The list includes the USDA Harmonized GAP Audit, the standard USDA GAP Audit, GroupGAP, Mushroom GAP, California LGMA, Arizona LGMA and California CCAB.

Which one you need is usually decided by the customer. A retail chain may require a Harmonized GAP audit specifically. A grower producing mushrooms may need Mushroom GAP, known as MGAP. GroupGAP lets a group of farms share one audit structure, which is how smaller operations that could not carry the cost and paperwork alone often get into the system. The leafy greens marketing agreements tied to California and Arizona exist because those states' lettuce and leafy green industries built their own additional standards on top.

That list is the first thing to check before filing anything, because requesting the wrong audit means paying for the wrong visit.

Who sets the standards, and who merely enforces them

The federal side and the state side do different jobs, and mixing them up causes most of the early confusion.

The USDA's Agricultural Marketing Service runs the audit programmes. It sets the checklists, trains and assigns auditors, collects the fees and maintains the public-facing list of certified companies. Its authority here is contractual: you ask for the audit, you agree to the terms, you get a certificate or you do not.

The Ohio Department of Agriculture's Division of Food Safety occupies a different position. Its stated purpose is to help assure consumers are provided foods, over-the-counter drugs, dietary supplements and cosmetics that are safe, unadulterated and honestly presented. Division staff work toward that through regulatory oversight of the wholesale and retail industry, plus contracts, partnerships and educational activities with federal, state and local food regulatory agencies.

Regulatory oversight is the phrase that separates the two. The Produce Safety Rule establishes a minimum set of food safety standards for farms to follow in order to reduce the risk of microbial contamination during the growing, harvesting, packing and holding of fresh fruits and vegetables for human consumption. A GAP audit asks whether you meet a buyer's standard. The Produce Safety Rule asks whether you meet the state's.

The federal audit programmes and how to enter them are set out on the USDA GAP audit page, which is the place to confirm current programme names before you commit to anything.

How an Ohio farm actually requests an audit

The sequence has more steps than most growers expect, and the first one does not involve the audit at all.

A new applicant must first establish a billing account with USDA/AMS by completing the SC-430 Vendor Form and submitting it according to the form's completion instructions. A farm that already has an account but has changed something, an address, a name, a contact, submits the same form again with the updates. Nothing moves until the account exists, because the audit is billed.

Then comes the choice of audit type, as above. Then two more forms: the Request for Audit Service Form SC-237A and the Agreement for Participation in Audit Services Form SC-651. Both are completed, and both are then emailed or faxed to the office selected from the list of Local Specialty Crops Inspection Division audit offices, the one closest to the facility that needs auditing. Non-domestic audits go through the national office instead.

That office confirms receipt, explains the programme procedures and schedules the visit. Nothing about this is instantaneous, which is the practical argument for starting the paperwork in the quiet part of the season rather than the week a buyer asks.

What changes on 1 October 2026

The GAP programme news list carries an audit fee increase effective 1 October 2026. The page does not publish the amount of the increase, so a grower budgeting for the coming year should ask the contact below directly rather than guess.

The same news list notes new USDA GAP water FAQs and records that the aquaponics pilot has moved to permanent policy. That last item matters to a small but growing group of Ohio operations that raise fish and plants in the same water, since it moves them out of a temporary status and into a settled one.

Does anyone check what the certificate claims?

That is the question a buyer should be asking, and the answer is built into the system rather than bolted on. The USDA maintains a searchable list of GAP-certified companies, and it can be queried by location, by commodity, by company name, or by audit type combined with commodity, location and company name.

So a buyer in Cleveland who wants a Harmonized GAP certified cucumber supplier in a given county can look it up rather than take a certificate's word for it. A grower can equally check how a neighbouring operation appears in the same listing, which is useful when a buyer's requirement is worded vaguely. The programme also publishes site instructions for using the search.

What the programmes do not cover

Food safety standards are not the whole of what an Ohio produce farm is measured against, and the state's food safety division page ranges wider than produce. It carries a cyclospora outbreak notice, describing cyclosporiasis as an intestinal illness caused by a microscopic parasite. It offers consumer food safety guides covering the route from grocery store to home. It lists cottage foods, a home bakery programme, a farmers market section, food safety educational programmes and workshops for sanitarians, a downloadable list of licensed hemp processors, and a page on learning about food production requirements for anyone starting a food business. A Resilient Food Systems Infrastructure Grant window is noted as having closed on 15 March 2024.

Sustainability, in the sense a buyer's questionnaire usually means it, does not appear as a single auditable standard on either page. What appears instead are separate programmes and separate rules, each with its own scope.

Where the paper trail ends and the farm begins

Two forms, a billing account, an office chosen from a list, a fee that rises on 1 October 2026, a certificate that a buyer can look up by commodity and county. That is the machinery.

The telephone number for the audit programme is (202) 720-5021, the fax is (866) 230-9168, and the email address is [email protected]. A grower who wants to know what a specific buyer will accept, and what the October increase does to the bill, can settle both questions in one call before the forms are filled in.

USDA Agricultural Marketing Service, GAP audits. The federal page describing voluntary Good Agricultural Practices audits, which verify that fruits and vegetables are produced, packed, handled and stored to minimise microbial food safety hazards. It lists the audit types available (Harmonized GAP, USDA GAP, GroupGAP, Mushroom GAP, the California and Arizona LGMA programmes and California CCAB), the forms and billing account needed to request an audit, the searchable list of certified companies, and programme news including a fee increase effective 1 October 2026.
