If you process food under HACCP, GMP or ISO 22000 certification, operate a pharmaceutical laboratory with a clean room, manage a cold room where wood is contaminated by condensation, or export food to the USA and Europe with a buyer's sanitary audit, the hygienic plastic pallet is the only option that performs in continuous audit without corrective notes. This guide explains how to choose between American (120×100 cm) and European (120×80 cm), how to apply the washing and disinfection protocol between cycles, how to segregate contaminated batches and how to document pallet traceability in your quality management system.
The hygienic pallet differs from the standard 3-runner plastic pallet in two critical points: the HDPE is virgin food-grade certified (not regenerated, not mixed with recycled materials of unknown origin) and the geometry is designed to minimize organic residue accumulation points and allow complete drainage after washing. If your operation does not require active sanitary certification, the 3-runner pallet standard complies at a lower cost. If certification is required, the extra cost of the hygienic pallet is justified by the risk of not passing an audit with the standard pallet.

Step-by-step usage guide
The following procedure covers the operational cycle under sanitary standards: integration into the client's HACCP protocol, palletizing, washing between cycles, segregation, and traceability. The instructions apply to both variants and supplement—not replace—your quality management system's written protocol.
HACCP/GMP Protocol Integration
Before incorporating the hygienic pallet into the production circuit, integrate the item into your plant's HACCP manual: identify the pallet as a control point in the goods flow, define the visual inspection frequency (at least at the beginning of each shift), establish the washing and disinfection protocol between batches, and link the pallet to an identification number for traceability. Request the technical data sheet with food-grade virgin HDPE conformity declaration from Cargobo to include it in the audit file.
Visual Inspection and Palletizing
Before loading, visually inspect the pallet: discard any unit with cracks, broken corners, dry organic residues stuck to the surface, or deformations indicating structural fatigue. Pallets with structural damage are segregated to a low-risk area for repair or controlled disposal, NEVER returned to the sanitary circuit. Place packaged goods (sealed boxes, pallets with plastic-wrapped product, closed sacks) centered and within the perimeter. For the food industry, avoid direct contact between unpackaged product and the pallet—there should always be a barrier (box, plastic, canvas).
Washing between cycles
Washing between cycles is what distinguishes the operational hygienic pallet from one that only bears the label. Standard procedure: initial rinse with pressurized water (60–80 bar) to remove visible solid and organic residues, washing with food-grade neutral detergent and a hard-bristle brush for corners and joints, intermediate rinse, disinfection with the protocol solution (chlorine diluted to 200 ppm, peracetic acid at 0.1–0.3% or quaternary ammoniums according to client specification), final rinse and complete draining. The surface must be visually clean and air-dried or passed through a drying tunnel before the next use.
Segregation by zones and color codes
In professional HACCP operations, pallets are segregated into zones (raw material reception, production line, finished product warehouse, dispatch) and DO NOT migrate between zones to prevent cross-contamination. Identify each zone with a color code (indelible label on the side of the pallet) or control number. If the end customer requires allergen-segregated products (gluten-free plant, nut-free, etc.), maintain exclusive batches of pallets for that flow, washed in a separate circuit. Discipline in segregation is what passes the audit; a pallet from the raw meat area used in finished product packaging is a "critical finding" in HACCP.
The recurring audit plant that has gone three years without observations typically keeps a "retired pallets log" where it records the date, reason (crack, deformation, persistent residue after washing), and destination (repair, controlled disposal). This log provides the auditor with objective evidence that the system works and defective pallets do not re-enter the circuit. Implementing it costs one Excel sheet and half an hour a week for the plant manager, and it's worth more than the supplier's food-grade seal the day the auditor asks "what do you do with damaged pallets?".
Traceability and record-keeping
For food exports to the USA and Europe with buyer audits, maintain a traceability system per pallet: pallet number, product batch loaded, departure date, return date (if applicable), last wash and disinfection date, observations. Modern industrial systems use RFID tags embedded in the pallet for automatic recording when passing through ramp doors; in simpler operations, a painted number on the side face with an indelible seal and manual recording suffice. The investment in traceability pays off on the day of a market recall or a sanitary alert, where tracing the pallets that touched the affected batch prevents a complete stock recall.
Do not mix hygienic pallets with standard pallets from the general industrial circuit. The usual mix occurs when a standard pallet enters the food production area "because no hygienic ones were available," contaminates a batch of finished product with its non-certified surface, and ruins the quality traceability of the entire shift. The color differentiation (standard food-grade blue) is deliberate so that the supervisor immediately identifies a "foreign" pallet in a sanitary zone. If your rotation requires more hygienic pallets, buy more; never fill in with standard pallets.
Hygienic or standard for your food operation?
The hygienic pallet covers operations under active, recurring audit standards; the standard 3-runner pallet is suitable for general distribution of packaged foods without certification requirements. Overpaying for hygienic pallets in simple distribution is wasteful; saving money with standard pallets in a certified plant risks failing an audit. Ask our assistant with your scenario, and we will guide you to the correct choice based on the actual audit level.
Complementary Products
To complement the hygienic plastic pallet in operations under continuous sanitary standards, the following products cover the most common adjacent needs:
The standard 3-runner plastic pallet is the complementary option for general industrial areas without active sanitary certification, maintaining geometric compatibility with racks. The reversible plastic pallet is an alternative for cold rooms with sack stacking, where the double face distributes wear and tear, and the smooth base protects the merchandise below. Transparent manual stretch film is the natural tool for wrapping loads on the pallet without leaving residue on the surface. The plastic box pallet with modular accessories is the option when the product is handled in bulk and requires a structural container—ideal for harvesting and intermediate transport under HACCP—.
Maintenance and Care
Hygienic pallets require more demanding maintenance than standard ones due to sanitary conditions. The washing protocol is covered in step 3; good practice for continuous maintenance also includes: visual inspection of each pallet at the end of the shift (not just at the start of the next), immediate removal of pallets with persistent residue that standard washing did not remove, and a quarterly review of the structural integrity of the entire fleet to identify fatigued pallets that would be dangerous to use under load at height.
For storing empty stock, stack them in a dry area segregated from other pallet families, ideally covered with a tarp or plastic to prevent dust accumulation between washes. Pallets that have been unused for a long time (more than 1 month) must go through the full washing cycle before being returned to production. Document the empty stock warehouse as part of the HACCP record. If your seasonal rotation involves high peaks followed by months of low activity, consider maintaining a minimum active fleet in circulation and the rest in stabilized stock with periodic validation cycles before reactivation.
Frequently Asked Questions (FAQ)
What is the difference between virgin food-grade HDPE and standard HDPE?
Virgin food-grade HDPE is manufactured with non-recycled resins, without dyes, plasticizers, or additives not approved for food contact, with a declaration of conformity according to FDA, CE, or equivalent. Standard HDPE may contain recycled resins (from uncontrolled sources) and additives that improve processability but are not suitable for food contact. For HACCP audits, the details are critical: the auditor will ask for the manufacturer's technical data sheet and declaration of conformity. Pallets without this documentation are considered uncertified and will result in an "finding" during the audit. Cargobo provides the corresponding documentation for hygienic pallets upon request.
Can I use it in a cold room?
Yes. HDPE does not become brittle at typical cold room and industrial freezer temperatures (up to -25 °C for continuous operation). In fact, a cold room is one of the environments where hygienic plastic pallets make more sense than wood: wood absorbs moisture from condensation and becomes a breeding ground for fungi and bacteria, contradicting the very purpose of the cold room. Keep the cold room pallet fleet segregated from the rest and apply the same washing protocol, ensuring complete drying before returning to the cold room to prevent ice formation on wet pallets.
Do I need a certificate to export food on this pallet?
The hygienic plastic pallet does not require an ISPM-15 phytosanitary certificate (not applicable to plastic) or special export authorization due to its condition. What you do need for food exports is the product's sanitary documentation (export certificate from the Ministry of Agriculture of the country of origin, sanitary act from the buyer, laboratory analysis if applicable) and, optionally, the manufacturer's food-grade declaration of conformity for the pallet in the file. If exporting to the USA, the FDA requires registration of the exporter's facilities; if exporting to the EU, it requires a sanitary certificate from the official veterinarian for animal products. Confirm specific destination requirements with your customs agent before shipment.
