In conjunction with the National Grain and Feed Association and the railroads, the Last Three Loaded STCC application addresses certain provisions of the Food Safety Act concerning “cross-contact” with allergen commodities. With Last Three Loaded STCC, users can search for the most recent Standard Transportation Commodity Codes (STCCs) and Waybill Dates from the three most recent loaded waybills. This application also supports railroad opt-in for Option B where searches for the last loaded STCC are unfiltered and the next 2 loaded STCCs are filtered to show allergens.
