Abstract: A plastic pallet cover is specially formed as a one-piece, high-strength device for ideally isolating a pallet load from the wood surface of a pallet. The pallet cover thereby protects the load from being contaminated by any bacteria, mold, or other disease-causing agents on the pallet, and provides a safe and sanitary surface for the storage and transport of food product loads such as shellfish or other edible products susceptible to contamination. The pallet cover is preferably made of plastic formed by the molding process to include a horizontal upper surface which fits over a conventional wooden pallet to isolate the pallet from the load, as well as a grid of internal ribs and edge walls to provide strength, rigidity, and positional stability.
