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.

That penetration is super exaggerated. Ever cut through a stained (i.e. pigment-stained) board? Board painted with a water-based paint? Those paint pigment particles are same scale as microbes, so you should expect them to penetrate to similar depth. Surface cleaning and routine abrasion get rid of most of it. Go over the surface with a scraper - take off 20-50 microns - and you're pretty much down to virgin wood.
