TL;DR: Food plants get audit findings on wood pallets and bins because wood is porous, hard to sanitize, and sheds splinters and nails. FDA's current good manufacturing practice rule requires equipment and utensils to be cleanable and kept in a way that protects food (21 CFR 117.40).
You do not need to replace every wood pallet: switch the areas where product or ingredients contact the container, or where the unit enters washdown or processing zones, to cleanable HDPE pallet boxes. LT Plastics, an authorized Bonar Plastics distributor based in Phoenix, AZ, supplies HDPE containers, pallet boxes and speed bumps to US plants and distribution centers.
Quick Facts
| Area | Wood acceptable? | Typical choice |
|---|---|---|
| Direct food or ingredient contact | Generally not | FDA-compliant HDPE pallet box |
| Processing / washdown zone | Avoid | HDPE, washable |
| Raw receiving outside process | Often | Wood or plastic pallet |
| Finished goods outbound | Often | One-way pallet |
| Waste / inedible | Yes with separation | Color-coded HDPE bin |
Why Wood Gets Flagged
Auditors look for foreign material risk and cleanability. Wood absorbs moisture, can harbor microorganisms in its surface, and breaks into splinters and loose nails. If the plant cannot show how wood equipment is cleaned and inspected, it becomes a finding under the facility's food safety plan.
Plan the Switch by Zone
Cost Thinking
HDPE costs more per unit but lasts many trips and cleans in place. Compare cost per trip with cardboard vs HDPE pallet boxes. For traceability rules that also touch containers, see the FSMA 204 checklist.
What We Know That Buyers Often Miss
Replacing all wood at once is expensive and unnecessary. Auditors care about the zones where risk is real. A zone-based switch spreads cost and closes findings faster.

FAQ
Are wood pallets banned in food plants?
Not by a blanket rule. They are risky in contact and processing areas because they are hard to clean.
Can HDPE pallet boxes go in washdown areas?
Yes. HDPE does not absorb water and can be washed; follow your sanitation procedure.
What documents prove a pallet box is food-safe?
A supplier statement that the resin complies with FDA 21 CFR 177.1520 for the intended use.
