Are wood delivery pallets making us sick?

Have you ever stopped to think that about 80% of every food item is delivered on wood pallets? Recent tests show that these pallets are never cleaned. Vegetables, fish, bread…just about everything is transported on wood pallets. Here is the problem: the wood in the pallets are absorbing blood that has dripped from different food and animal products. In some cases, ecoli emerges and transfers its bacteria to other foods and then to you and I from the same pallet. Question: is there a better and healthier way to transport our food, other than wood pallets?
