7 Farm Audit Mistakes That Cost Kenyan Farms Their Certification

Most Kenyan farms that fail their GLOBALG.A.P audit do not fail because of catastrophic problems. They fail because of a small number of consistent, entirely preventable mistakes that appear on audit reports across the country year after year. Understanding these mistakes — and eliminating them from your farm before the auditor arrives — is the most efficient audit preparation investment you can make.

This guide covers the seven mistakes that most commonly cost Kenyan export farms their certification. Every one of them is avoidable. Every one of them has been seen on real audit reports from farms in Kiambu, Meru, Nakuru, and Machakos. And every one of them can be fixed before your next audit with the right preparation.

Mistake 1: Incomplete Pesticide Application Records

This is the single most common Major Must non-conformance on Kenyan GLOBALG.A.P audits. Incomplete pesticide records appear in two forms — records that are missing entirely for some applications, and records that exist but are missing required fields.

A pesticide application record that captures the product name and application date but omits the pre-harvest interval, the operator name, or the field applied is not a compliant record. GLOBALG.A.P requires every field on the record to be completed for every application. A record with blank fields is treated as a missing record for that application.

The most commonly missed fields on Kenyan farm pesticide records are the pre-harvest interval — which many farm operators record as “N/A” rather than the actual number of days — and the equipment used. Both are required fields. Both generate non-conformances when blank.

The fix is straightforward. Use a standardised pesticide application record form with every required field pre-printed. Train whoever keeps the records — whether the farm manager or a designated record keeper — on the requirement that every field must be completed for every application before the record is filed. Review records weekly rather than monthly to catch missing information while the application details are still fresh.

Mistake 2: No Soil Test to Justify the Fertiliser Programme

GLOBALG.A.P requires that fertiliser applications are based on demonstrable crop need — supported by soil analysis, tissue analysis, or visual crop assessment documented in a structured format. A farm that applies a fixed fertiliser programme — the same products at the same rates every season regardless of soil condition — without any supporting analysis fails this requirement.

The most common version of this mistake is a farm that has excellent fertiliser application records — every application documented correctly — but has never conducted a soil test. The auditor finds complete fertiliser records but no soil test results. The fertiliser records demonstrate what was applied but cannot demonstrate why it was appropriate to apply. This generates a Major Must non-conformance.

Soil testing in Kenya is accessible and affordable. KEPHIS laboratories and private agricultural laboratories across Kenya conduct standard soil analysis for KES 2,500 to KES 6,000 per sample. One soil test result — even if it is two years old — combined with a fertiliser programme that can be justified against those results is sufficient for most audits. See our full guide on soil management for Kenyan export farms for detail on soil testing requirements.

Mistake 3: Outdated or Missing Water Test Results

GLOBALG.A.P requires that water used for irrigation and post-harvest produce washing is tested for microbiological quality — specifically E. coli contamination — at a frequency appropriate to the risk. For most Kenyan smallholder farms, this means at least one water quality test per production season from each water source used.

Two versions of this mistake appear regularly. The first is farms that have never tested their irrigation water at all — operating on the assumption that borehole or river water is clean because it looks clean. The second is farms that tested their water two or three years ago and have not repeated the test. Water quality from the same source can change significantly between seasons — particularly for farms using river or dam water that may be affected by upstream activities including pesticide runoff from neighbouring farms.

Water testing at an accredited laboratory costs KES 1,500 to KES 3,500 per sample for a standard microbiological test. The cost of a failed audit because of missing water test results is incomparably higher — both financially and in terms of delayed market access.

Mistake 4: Workers Who Cannot Answer Basic Safety Questions

Worker interviews are one of the components of a GLOBALG.A.P audit that farms most consistently underestimate. A farm can have perfect records and a well-organised pesticide store and still generate significant non-conformances because workers cannot demonstrate basic knowledge of the safety procedures they are supposed to follow.

The questions auditors ask workers are not complex. Where is the first aid kit? What do you do if you spill chemicals on your skin? Do you know what the re-entry period is after a pesticide application? Have you received training on safe pesticide handling? Workers who have genuinely received this training and use these procedures daily should be able to answer these questions without difficulty.

Workers who cannot answer basic safety questions generate two problems simultaneously. They create a direct non-conformance for worker training compliance. And they create doubt in the auditor’s mind about whether the farm’s training records — which may show training was completed — reflect reality. Once an auditor begins questioning the accuracy of farm records, the entire audit becomes more difficult.

The solution is genuine training — not pre-audit coaching with scripted answers. Workers who understand why pesticide safety matters and have genuinely practiced safe procedures will always perform better in worker interviews than workers who have been given a list of answers to memorise.

Mistake 5: Pesticide Store Non-Compliance

The pesticide store is one of the first places an auditor walks during a farm inspection — and one of the areas that generates the most non-conformances on Kenyan farms. GLOBALG.A.P requirements for pesticide storage are specific and non-negotiable.

The most common pesticide store failures on Kenyan farms are unlocked stores — a Major Must requirement that the store be lockable and locked when not in use — chemicals stored in unmarked or re-used containers, incompatible chemicals stored together without separation, open or damaged bags not segregated and labelled, and no spill containment. Personal protective equipment stored in the same space as pesticides also generates a non-conformance — PPE must be stored separately to prevent contamination.

A compliant pesticide store does not need to be an expensive or elaborate structure. A lockable metal cabinet or a dedicated room with a secure lock, proper ventilation, secondary containment for liquid products, and organised shelving with all products in original labelled containers meets the requirement. The investment required to bring a non-compliant pesticide store into compliance is almost always under KES 15,000 — a fraction of the cost of a failed audit.

Mistake 6: A Broken Traceability Chain

GLOBALG.A.P requires that any lot of produce can be traced from the point of sale back to the specific field and harvest date within four hours. This traceability requirement exists to enable rapid product recall if a food safety issue is identified — a non-negotiable requirement for any buyer operating in regulated export markets.

The traceability chain breaks most commonly at one of two points. The first is between the field and the collection point — harvested produce from multiple fields or farms is mixed without lot identification before it reaches the packhouse or collection point. Once mixed, individual farm or field origin is lost and the traceability chain is broken. The second break point is between the packhouse and the buyer — packed product is shipped without lot numbers that can be linked back to the harvest records.

For smallholder farms, a simple traceability system using field codes, harvest date records, and lot numbers on packed produce boxes is entirely adequate. It does not need to be digital or complex. What it must be is consistent — applied on every harvest, for every field, without exception.

Mistake 7: Ignoring Minor Must Accumulation

GLOBALG.A.P requires that at least 95 percent of all Minor Must requirements are met for certification to be granted. This means a farm can have up to 5 percent of Minor Must requirements unmet without failing — but farms that ignore Minor Must requirements entirely because they are “not Major” often accumulate enough minor non-conformances to breach the 95 percent threshold.

The total number of Minor Must requirements under GLOBALG.A.P IFA for crop production is over 100. Five percent of 100 is 5 — meaning a farm can have a maximum of five unmet Minor Must requirements before failing on this threshold alone. Farms that approach the audit with a list of known Minor Must gaps — “those are just minors, they won’t fail us” — regularly discover that their accumulated minor gaps exceed the threshold.

Treat Minor Must requirements with the same seriousness as Major Must requirements during your audit preparation. A failed audit because of accumulated minor non-conformances is no less costly than a failed audit because of a single major one.
