Hazard Analysis and Critical Control Points: a preventive food safety system that identifies hazards and controls them at critical points; pallets are considered as a possible source of contamination.
Detailed Definition
HACCP is a systematic approach to food safety built on seven principles: conduct a hazard analysis, determine critical control points (CCPs), set critical limits, establish monitoring, establish corrective actions, establish verification procedures and keep records. It is required by regulation for some sectors in the US, including seafood and juice under FDA rules and meat and poultry under USDA FSIS. The FSMA preventive controls rule in 21 CFR Part 117 uses a similar hazard analysis approach but is a separate requirement. Pallets usually appear in HACCP plans as a prerequisite program item rather than a CCP.
How pallets fit into a HACCP program
Most plants handle pallet risks through prerequisite programs such as sanitation, pest control, supplier approval and equipment maintenance, not through a CCP. The hazard analysis should still consider pallets, because they can bring in:
- Physical hazards: splinters, loose nails and wood fragments.
- Biological hazards: mold, pests and contamination from previous use.
- Chemical hazards: spills absorbed into wood, or treatment chemicals.
Controls typically include incoming pallet inspection, keeping wood pallets out of open-product areas, using plastic or dedicated pallets in production, and pallet storage away from processing lines.
Common mistakes
One mistake is treating pallets as outside the food safety system because they never touch product. Pallets travel through receiving, storage and shipping and can carry contamination with them. Another is buying recycled pallets with no history for use near exposed food. A written pallet specification, approved suppliers and regular inspection give auditors evidence that the risk has been assessed.
Records matter as much as the controls. Keep the pallet specification, supplier approvals, inspection logs and any rejected-load notes where auditors and customers can see them, and review them when the pallet supplier or pallet type changes.

Frequently Asked Questions
Is HACCP required by FSMA?
Not exactly. Most FDA-registered human food facilities must follow the hazard analysis and risk-based preventive controls requirements in 21 CFR Part 117, which share many ideas with HACCP but are broader. Facilities already covered by FDA's seafood or juice HACCP rules are generally exempt from those preventive controls provisions. Meat and poultry plants follow USDA FSIS HACCP regulations. Many companies also use HACCP within certification schemes their customers require.
Should pallets be a critical control point?
Usually not. A CCP is a step where control is essential to prevent or eliminate a significant hazard, such as a cooking or metal detection step. Pallet risks are normally managed by prerequisite programs such as inspection, sanitation and supplier control. A plant's own hazard analysis decides this, and in an unusual process a pallet-related step could be significant, but most HACCP teams do not make pallets a CCP.
