Food-grade pallets are designed for use in food manufacturing, distribution, and storage.
Detailed Definition
Food grade is a trade description, not a federal certification. Under FSMA rules, equipment used with food must be suitable, adequately cleanable and kept in sanitary condition, and buyers turn that into a written spec. Typical requirements include clean, dry wood or plastic, no chemically treated wood, no visible mold, stains, odors or loose debris, and heat treatment rather than methyl bromide where treated wood is needed. See also sanitary pallet.
What buyers usually put in a food-grade pallet spec
- Material: new or carefully sorted recycled wood, or plastic, as the food safety plan allows.
- Condition: no mold, stains, oil, odors, loose nails, bark or splinters that could reach product or packaging.
- Moisture: dried wood, since wet pallets support mold; many specs set a maximum moisture content.
- Treatment: heat treated wood where treatment is needed, not methyl bromide or other chemicals.
- Traceability: a supplier or lot identifier so problems can be traced back.
Wood or plastic for food use
Plastic pallets can be washed and sanitized, which is why many processing plants use them inside clean areas. Wood is porous and harder to sanitize, but clean, dry wood pallets are widely used in food distribution where product is packaged. Some operations use plastic inside production and transfer loads to wood at shipping. Whatever the material, inspect pallets at receiving and pull any that are wet, contaminated or damaged before they reach food areas.
Storing and handling pallets for food use
Even a clean pallet can become unsuitable if it is stored badly. Keep pallets for food use indoors or covered, off the ground, away from chemicals and pests, and separate from scrap or damaged stock. Rotate stock so pallets do not sit long enough to pick up dust or moisture, and recheck condition just before loading.

Frequently Asked Questions
Are recycled pallets acceptable for food use?
They can be, depending on your food safety plan and your customers' requirements. Recycled pallets have unknown histories, so they may have carried chemicals or been stored outdoors. If you allow them, set clear sorting rules: dry, clean, no stains or odors, no mold and no sign of chemical exposure. Many processors handling exposed food choose new or dedicated pallets instead, while distributors of sealed, packaged food often accept well sorted recycled pallets.
Does heat treatment make a pallet food safe?
Not on its own. ISPM 15 heat treatment is a pest control step for international shipping. It kills insects in the wood at the time of treatment, but it does not sterilize the pallet for life, prevent mold if the wood gets wet later, or remove dirt picked up in use. A food-grade pallet still needs to be clean, dry and in good condition when it reaches the food area, whatever its treatment mark says.
