Our facility is going for SQF certification in approximately 4 months. We are currently addressing shelving in our facility, and more specifically metal shelving with particle board or plywood shelves (unsealed with no painted surface).
Do we have to either replace or seal any wood shelves, or can we continue using in areas where we are not storing ingredients, chemicals, food-contact materials and primary packging? My initial thought is to replace or seal wood shelving which is used for storing the previously stated items, but in areas such as maintenance maybe we can get away with it?
