GAP Certification Basics

What is GAP certification?

Good Agricultural Practices, often shortened to GAP, are food safety practices for growing, harvesting, packing and storing fresh produce. A GAP audit or certification is a review by an outside auditor who checks whether your farm follows a standard. If you pass, you receive documentation you can show to buyers.

Several programs and standards exist, and they are not all the same. Some are run by government agencies and some by private organizations. Ask the buyer which standard they accept before you start.

Many farms discover that preparing for an audit improves their daily habits even when they decide not to be certified. Writing things down forces you to notice where your routine has gaps.

• An outside auditor reviews your practices and records.
• Different programs have different standards.
• A passing audit gives you paperwork for buyers.
• Audits are often repeated each year.

Why do some buyers ask for it?

Large buyers such as distributors, institutions and chain stores often ask suppliers for proof of food safety practices, because they carry responsibility for what they sell. Smaller buyers, farmers markets and many direct customers rarely ask.

Before pursuing certification, ask your actual or likely buyers whether they require it and which program they accept. Do not assume that every buyer needs the same thing.

• Ask each target buyer what they require.
• Ask which audit programs they accept.
• Find out whether a written food safety plan alone would satisfy them.

How is GAP different from legal food safety rules?

Certification is voluntary and often driven by buyers, while legal food safety rules are set by governments and may apply whether or not a buyer asks. A farm can be covered by a legal rule without being certified, and a farm can be certified while still being responsible for following the law.

Ask your state department of agriculture how federal and state rules apply to your farm, and treat certification as an additional step if a buyer needs it.

What does an audit usually look at?

Audits typically review worker hygiene and training, water sources and use, soil amendments, animal and wildlife risks, equipment cleaning, harvest and packing practices, traceability and written records. Auditors usually look at both what you do and what you can show on paper.

Many farms find that the documentation is the harder part. Keeping simple, dated records during the season makes an audit much easier.

• Worker hygiene and training records.
• Water testing and use records.
• Cleaning and sanitation logs.
• Traceability from field to buyer.

What are the costs and the time involved?

Cost categories include audit fees, training, written plan preparation, any changes to facilities such as handwashing stations, water testing and the time to keep records. Fees vary by program and by farm, so ask programs directly rather than relying on numbers from other farms.

Time is the larger cost for many small farms. Be realistic about how many hours per week you can spend on records during the busy season.

Ask the auditor or program for a sample checklist and fee schedule before you sign up. You will see what is required and can plan time and money before committing.

Are there options for small farms?

Some programs offer group certification, in which several small farms share a system and audit. Some state departments of agriculture and extension services run training, cost-share or assistance programs. Availability differs by state and changes over time.

Ask your state agriculture department, your extension office and nearby farms what is available. A group approach can lower the cost for a small farm, but it needs trust and consistent practices among members.

Talk with a farm that has been through a group audit and ask how members handled disagreements about records and standards. Group programs work best when every member takes the paperwork seriously.

• Ask about group certification.
• Ask about training and cost-share help.
• Talk to farms that have been audited.

How do you decide whether to pursue it?

Ask whether you have a buyer who requires it, whether that sale is large enough to justify the effort and whether you can keep the records the audit needs. If the answer to the first question is no, a simple written food safety plan and a training course may serve you well without certification.

If you do go ahead, start by taking a food safety course and writing your plan. Do a practice review of your own farm using the audit checklist before you pay for the real one.
