(2) MILK CONTACT SURFACES; CONSTRUCTION. Milk contact surfaces of milking and milk handling systems shall be constructed of smooth, nontoxic, and nonabsorbent materials. Materials shall be of any of the following types, unless another material is specifically authorized by the division in writing:(a) Stainless steel of the American Iron and Steel Institute 300 series, or an equally corrosion resistant metal.(b) Heat resistant glass.(c) Plastic, rubber, or rubber-like materials that are fat resistant and insoluble; that are resistant to scratching, scoring, decomposition, crazing, chipping, and distortion under normal use conditions; that do not impart chemicals, flavor or odor to milk; and that maintain their original properties under repeated use conditions.(3) MILK PIPELINES. (a) Milk contact surfaces of permanently mounted milk pipelines shall be constructed of stainless steel or an equally non-toxic, corrosion resistant metal, or of heat resistant glass. Plastic or rubber-like materials may be used for pipeline gaskets, connections, and sealing applications, but not for other purposes. Paper gaskets are prohibited.(b) All joints of permanently mounted milk pipelines, including joints in solution lines, shall be welded or equipped with fittings designed for C-I-P. Welded joints shall be smooth and free of pits, cracks, or other defects. Removable fittings shall be designed to form substantially flush interior joints.(c) Permanently mounted pipelines shall be supported at intervals of not more than 10 feet so that the pipelines remain in constant alignment and position. Permanently mounted pipelines shall be self-draining, and shall have a minimum slope of one inch per 10 feet. The support system shall be designed and constructed to prevent electrolytic reactions between supports and pipelines.(d) Milk pipeline systems shall be designed and constructed so that cleaning, rinsing and sanitizing solutions cannot enter the pipeline while milk is being transferred through the pipeline.(4) NON-PIPELINE SYSTEMS. The transfer of milk to the milkhouse by a method other than a pipeline or vacuum transfer system shall comply with requirements under s. ATCP 65.18(2). If milk from milking animals is initially collected in a portable transfer receptacle and pumped to the milkhouse through a flexible tube, rather than being pumped directly to the milkhouse through a permanently mounted pipeline, the transfer receptacle and tube system shall comply with the following requirements: (a) The portable transfer receptacle shall be constructed of stainless steel or an equally corrosion resistant metal and shall have an overlapping self-closing cover. The receptacle shall be supported off the floor on a cart or mobile structure that can be easily cleaned.(b) The tube used to transfer milk from the portable transfer receptacle to the milkhouse shall consist of a single length of transparent tubing material. The milk transfer tube shall be supported off the floor at all times. The interior milk contact surface of the transfer tube shall be mechanically cleaned and sanitized, and dried after each use. The opening through which the milk transfer tube enters the milkhouse shall be kept closed when the tube is not in use. A milk transfer tube shall not be left suspended in a milking barn or parlor between uses, but shall be stored in the milkhouse.(5) MILKING EQUIPMENT. (a) Surfaces of milking equipment, including surfaces of milker claws, inflations, weigh jars, meters, milk hoses, milk receivers, and milk pumps, shall be smooth and readily amenable to cleaning and sanitizing by mechanical or manual methods. If thorough cleaning requires the removal of any part, that part shall be easily removable. Milking equipment shall be designed and constructed so that milk, milk cleaning solutions, rinsing solutions, and sanitizing solutions will drain completely from the equipment.(b) Milking equipment that deposits milk into a bucket or container, rather than into a permanently mounted pipeline, shall be equipped with a check valve or other device that prevents moisture and contaminants from entering the milk through the temporary creation of vacuum. The moveable portion of the check valve shall consist of a single piece, or pieces that are permanently and completely bonded to each other.(c) Automated milking installations shall comply with the requirements of the Pasteurized Milk Ordinance Appendix Q of the PMO, and all of the following: 1. All equipment shall be designed for effective C-I-P cleaning and sanitizing.2. Valves and equipment shall effectively prevent the contamination of milk with abnormal milk or chemicals used in cleaning and sanitizing, in accordance with a written testing and verification procedure acceptable to the division. The written procedures shall be kept at the dairy farm and made available to a division representative upon request.3. The AMI shall ensure the detection, diversion and proper handling of abnormal milk, in accordance with a written testing and verification procedure acceptable to the division. The written procedure shall include a description of the equipment cleaning and sanitizing protocol to be followed after milking of animals whose milk is intended to be excluded from the collected milk, and before milking of animals whose milk will be shipped. The written procedure shall be kept at the dairy farm and made available to a division representative upon request.4. The AMI operator shall follow a written procedure for verifying the effectiveness of the computer software and hardware. The written procedure shall be acceptable to the division and shall be kept at the dairy farm and made available to a division representative upon request. The written procedure shall include the following items: a. A description of the location and function of all sensors used to control and monitor the operation of the AMI.b. A description of changes made to, or maintenance performed on, the AMI software, control and monitoring devices, instrumentation, and sensors; and other hardware associated with the AMI.c. Instructions on how to obtain operating information stored in the AMI computer system.5. The AMI operator shall keep a copy of the AMI manufacturer's teat preparation protocol and a written procedure for verifying the effectiveness of this protocol. This protocol shall be accepted by the federal food and drug administration and made available to a division representative upon request.6. Verification and records review to ensure compliance with subds. 1. to 5. shall be done at a frequency determined by the division. (6) REVIEW OF PLANS. (a) Before installing, reconstructing, or extensively altering a bulk tank, milking system, milk handling system, milkhouse, milking parlor, or dairy farm water supply system, the installer shall, on behalf of the milk producer, submit plans to the division for review. Plans for a new automated milking installation shall indicate how proper computer performance and compliance with sub. (5) (c) 1. to 3. are to be verified. The department shall charge a fee of $25, as allowed by s. 93.06(1w), Stats., to recover costs for providing the review service. The division shall return the plans, together with any comments or objections, within 14 days after the plans are received by the division. No review is required for a portable transfer receptacle or its appurtenances.(b) No manufacturer or distributor of milking or milk handling systems may sell, or distribute for sale in this state, any portion of a milking or milk handling system unless specifications or prototype equipment are first reviewed by the division. Within 30 days after specifications or prototype equipment are received by the division, the division shall return them with any comments or objections. The division may require field testing of the equipment prior to sale if the division finds that field testing is necessary to determine whether the requirements of this section are met. Field testing shall be conducted under conditions prescribed by the division.(c) Plans and specifications submitted under this subsection shall be sufficiently detailed to permit review by the division within the time periods specified under this subsection.(7) CERTIFICATION OF COMPLIANCE BY INSTALLER. A person who installs, reconstructs or extensively alters a milking system, milk handling system, milkhouse, milking parlor, or dairy farm water supply system shall certify to the owner of the system that the system has been installed or modified in compliance with this section and in compliance with the plans filed with the division under sub. (6) (a). The installer, immediately after installing or modifying the system, shall provide to the milk producer and the division a signed written statement certifying compliance.
