The standard method is a shoe sanitizing station placed at each zone transition — plant entrances, gowning rooms, and raw-to-cooked boundaries. Workers step onto the station, which applies sanitizer to the sole of the shoe or boot as they pass. For repeatable results, use an airless, foot-operated station like the Smart Step rather than a wet mat, which dilutes and dries out over a shift. Document station placement, chemistry, and refill cadence for your FSMA and HACCP records.
