Quality is what you get paid for. It is determined in the field, decided in the packhouse, and verified by an inspector who was not there for either.
Grading: what determines the price#
Criterion What is assessed Typical defect causes Size Finger length and diameter; hands per bunch Water stress at filling, variety, maturity Shape Straight, uniform fingers; no curvature or deformity Crowding, uneven filling, stress Colour Even green (for export); no greying or yellowing Chilling injury, heat damage Surface No scarring, stings, russeting, latex staining, soot Thrips, fruit fly, rough handling, dry latex Crown Clean cut, white to cream, no browning or rot Slow processing, ragged cuts, dirty water Firmness Hard and mature but not over-ripe Harvest timing Cleanliness No soil, no insects, no foreign matter Field and packhouse hygiene Uniformity Same size and maturity within a box Mixed blocks, mixed maturity at load
Representative export grade structure#
Grades vary by buyer and destination — the buyer's specification always overrides a generic table .
Grade Typical requirements Extra / Class I Well-formed, characteristic colour for stage, finger length at or above specification, no defects other than very slight superficial blemishes, free from rot and pests, clean cut crowns Class I Good quality; slight defects of appearance permitted that do not affect keeping quality or presentation Class II Quality defects permitted that do not affect keeping quality or edibility — often sold at a discount or to a different channel Reject Rot, pest damage, splitting, severe scarring, chilling or heat damage, off-size, off-maturity
Common downgrades and their real cause#
Downgrade Where the loss actually happened Split fingers Water stress or rain before harvest; over-maturity Brown crowns Delayed de-handing; dirty wash water; ragged cuts Latex staining Fruit left dry after cutting Bruising / pressure marks Throwing, deep stacking, hard surfaces Rubbing scars Missing propping; wind; tight packing Fruit fly stings Late harvest; no trapping; wild hosts nearby Thrips russeting No protection at bunch emergence Chilling injury Cold store below 13 °C Sunburn Insufficient shade / water in the field Size below specification Insufficient nutrition or water at filling
Food safety requirements#
Water#
Irrigation water quality assessed (EC, SAR, microbiology) — see Water management . Packhouse wash water must be potable-grade or demonstrably clean , changed regularly, and monitored where certification requires it.Overhead irrigation near harvest is discouraged — it puts non-potable water on fruit surfaces. Chemicals#
Requirement Detail Only approved products Registered for banana in your jurisdiction Label compliance Rate, frequency, PPE, buffer zone, re-entry interval Pre-harvest interval (PHI) The gap between last application and harvest — legally enforced and tested Maximum residue limits (MRLs) Destination-market specific; the EU and Japan are typically the strictest Storage and records Locked, labelled, inventory and application log Adulteration / counterfeits Buy from authorised distributors only
Biological hazards#
Personnel hygiene and hand-washing in the packhouse. No sick workers handling fruit. Control of birds, rodents and insects in packing areas. Clean and sanitise knives, de-handers, tables and tanks on a schedule. Drainage — no standing water near packing. Visitor and contractor hygiene procedures. Traceability#
Traceability is the ability to answer, for any box: which block, which harvest date, which crew, which treatments, which pack run.
Field Minimum content Block ID Unique code mapped to a field plan Planting Date, clone, planting material source Inputs Fertiliser, crop protection products, dates, rates, operators Harvest Date, block, crew, quantity, sample weights Packhouse Batch, date, line, grade, treatment applied, packer Dispatch Date, consignment, destination, cold-chain record Recall Ability to trace forward to customers and back to source
A recall that takes hours instead of days is the difference between a manageable incident and a lost buyer.
Certification schemes#
Scheme Focus Common requirement GLOBALG.A.P. Integrated farm assurance: food safety, environment, welfare, workers Traceability, input management, HACCP-based controls, internal inspection HACCP Hazard analysis at process steps Critical control points monitored and recorded in the packhouse Organic (various) Restricted inputs, no synthetic chemicals, buffer zones Conversion plan, inspection, segregation, record keeping Rainforest Alliance / Fairtrade Sustainability and social criteria Environmental management, community and labour standards PSR / retailer-specific Buyer programmes Often layer additional requirements on top of GLOBALG.A.P.
What an audit will look at#
Soil and water tests on file. Input register: what was bought, what was applied, by whom, when. Spray records with rates and PHI compliance. Equipment calibration. Worker training, PPE, contracts, and health provisions. Cleaning schedules in the packhouse. Traceability exercise: pick a box, trace it back. Waste, effluent and environmental management. Internal inspection and corrective actions. ! Certify for the market, not the wall
Choose certification because a buyer requires it or because it commands a measurable premium. Each scheme costs money and paperwork; add the cost to your farm budget before committing.
Handling standards (the practical core)#
Cut → de-hand within 2–4 hours. Deflux immediately — do not let latex dry.Clean cuts through the crown.Clean water, changed regularly. Treated and drained before packing.Padded surfaces everywhere. Cool to 13–14 °C within 1–2 hours of packing. Unbroken cold chain to the customer.Never store green fruit with ripening fruit. Record everything. Shelf life expectations#
Stage Condition Practical shelf life Green, export 13–14 °C, 90–95% RH, ethylene-free 2–5 weeks depending on cultivar and maturity Green, domestic Ambient shade, short transit 3–10 days Colour stage 3–4 (ripe) Ambient retail 3–5 days Fully yellow Ambient 1–3 days Yellow with spots Ambient Same day
Continuous improvement#
Track these five numbers monthly:
Metric Target direction Grade-out % at packhouse ↑ Hours from cut to cold ↓ Rejections and claims ↓ Residue test failures Zero Labour cost per tonne packed ↓
Feed every rejection back to a cause: field, timing, handling or cold chain. One rejection with a known cause is worth ten unexplained ones.
