The Best Food-Safe Finish May Be None at All - FineWoodworking

Seri Robinson, a professor of wood anatomy, agrees with the marketers of "food-safe" finishes that bacteria-especially salmonella, listeria, and E. coli-are a threat to human health. But, Robinson says, those finishes can undermine the natural antimicrobial properties of wood. If an unfinished wooden cutting board or spoon is rinsed after use and allowed to dry on all sides, the drying action will pull bacteria deep into the wood, where it will be trapped and die. A finish will keep bacteria close to the surface, where it will multiply.

Conventional wisdom regarding finishing cutting boards and other food prep surfaces is to coat them heavily with mineral oil and/or a food safe paste wax to “seal” and/or “condition” them. Seri Robinson asserts otherwise, her research has shown that any finish applied to wood decreases its natural anti-microbial properties.

    while partially true, unoiled wood also tends to take in any kind of fluid deeper, and that includes coffee stains, oil stains, and smells. i honestly don’t prefer my woodworks start smelling a bit over time.

      Yeah I’m not sure I’m going to stop oiling my counter. But if you just used a plank and replaced it every year? Probably better than spending $500 on a boos block and treating it like an heirloom.
