Pennsylvania Statutes Title 31 P.S. Food § 657. Cleanliness of containers

(a) Adequate facilities shall be provided and used for furnishing clean containers, free from injurious organisms, in which to sell “Raw Milk” or “Pasteurized Milk” or “Milk for Pasteurization” or “Milk Products.” Bottles or containers, whether of glass or other material, shall be filled and closed without any part of the hand coming in contact with the inner surface of the bottles or containers, or in contact with bottle caps. Caps shall be obtained in sanitary containers and kept therein until used.

(b) Milk cases in which bottled milk or milk products are owned and shipped by milk dealers or licensees shall also be maintained in a sanitary manner. It shall be unlawful for any person, firm or company, other than the name imprinted or stamped on such containers, or his agent, to alter, destroy or contaminate such containers. In addition, it shall be unlawful for any person in rightful possession of milk cases, but not the owner thereof, to permit any third party to alter, destroy or contaminate such containers. Each case so misused shall be deemed an individual offense under section 20 of this act.  1
