In no instance will containers which have previously been used for nonfood items be allowed to be use for the bulk handling of dairy products.

b)         Filling:  Empty containers shall be protected at all times from possible contamination and containers which are to be lined shall not be prepared more than 1 hour in advance of filling.  Every precaution shall be taken during the filling operation to minimize product dust and spillage.

The room and all packaging equipment shall be cleaned as often as necessary to maintain a sanitary operation.  Close attention shall be given to cleaning points of equipment where residues of the dry product may accumulate.   A thorough cleanup including windows, doors, walls, light fixtures, and ledges, shall be performed as frequently as is necessary to maintain cleanliness and sanitation.  All waste dry dairy products including dribble product at the fillers shall be identified and disposed of as animal feed.

1)         Product:  The packaged dry milk product shall be stored or so arranged in aisles, rows, or sections and lots at least 18 inches from any wall and in such a manner as to be orderly, easily accessible for inspection or for cleaning of the room.  All bags and small containers of product shall be placed on pallets elevated approximately 6 inches from the floor.  The storage room shall be kept clean and dry and all openings protected against entrance of insects and rodents.
