Does your facility have excessive floor traffic which could bring in Listeria?
Listeria can be tracked in on footwear and migrates to equipment and other plant surfaces.
The use of a floor treatment or floor foamers in primary traffic areas is recommended to control Listeria. In areas that stay dry (i.e. hallways, processing rooms, coolers), a dry floor
treatment, as appropriate for certain facilities, could be used and maintained (reapplied as necessary) by sanitation in processing and high traffic areas during hours of production. For areas that stay wet, strategically placed floor foamers to cover hallways, etc. may be more appropriate as floor treatments (as shown in the picture to the right) may become slippery when wet. S3 Sanitation Cleaning suggests, that additional floor foamers be placed throughout your facility in strategic locations as needed to minimize the risk of cross-contamination from foot and lift or cart wheel traffic.
It has also been noted to S3 Sanitation Cleaning that they should inspect, monitor and document the operation of the floor foamers on several occasions at predetermined times (every 4 hours or more frequently as needed) throughout the day for proper function (are they turned on and working), concentration of chemical, coverage, timing of foam application to ensure coverage is maintained and chemicals are not wasted, and any other necessary and critical elements of these systems. The responsible department(s) at your plant (production, QA, maintenance) should work to ensure that these floor foamers remain on during all hours of production. For improperly operating floor foamers, corrective actions should be developed and documented. When a correction requires the facilities’ maintenance, QA or production to be involved, S3 Sanitation Cleaning, if contracted to perform the sanitation duties, should maintain daily communication with the proper responsible person(s) at the facility, and follow up to verify (and document) the resolution of the issue and the resumption of normal activities.
