A paved surface of concrete or other readily cleanable material shall be installed adjacent to the outside wall of the milkhouse, immediately under the bulk tank hose port. The paved surface shall be at least a 4 foot by 4 foot square and shall cover as much additional ground area as is necessary to protect the milk hose from ground contamination.

ATCP 65.08(4)(4) Maintenance and sanitation. The floors, walls, ceilings, windows, hose port assembly, and all equipment of a milkhouse shall be kept clean and in a good state of repair. Liquid wastes from milkhouse operations shall be drained and removed in a sanitary manner. Equipment and utensils shall be cleaned and maintained in compliance with s. ATCP 65.12. A milkhouse shall be kept free of insects, rodents, and other pests. Animals shall be kept out of the milkhouse at all times. Potential sources of milk contamination, including materials that may attract or harbor pests, shall be excluded from the milkhouse.

ATCP 65.08(5)(a)(a) General. No equipment, supplies, or other articles may be stored in a milkhouse, unless the articles are used in milkhouse operations. Articles stored in a milkhouse shall be stored above the floor, on racks, or in a cabinet. Articles shall be stored in a manner that prevents both the contamination of milk and contact of equipment or utensils with milk. Washing machines, laundry dryers, and pasteurizers used to prepare milk-replacement formula for calves shall not be stored in the milkhouse.

ATCP 65.08(5)(b)(b) Drugs and medicinal items. No drug or medicinal item, or drug administering device such as a bolus wand or syringe, may be kept in a milkhouse unless it is intended or prescribed for use on dairy animals. If drugs or medicinal items are kept in a milkhouse, they shall be stored in an enclosed cabinet, separate from all other articles stored in the milkhouse. Drugs and medicinal items shall be clearly labeled to indicate their identity and intended use, and prescription drugs shall be labeled as provided under s. ATCP 65.20 (5). Drugs and medicinal items intended solely for treatment of non-lactating milking animals shall be kept separate from those used for treatment of lactating milking animals.

ATCP 65.08(5)(c)(c) Pesticides. No pesticides, except for sanitizers, germicides, disinfectants, or pesticides labeled and used for routine milkhouse sanitation purposes, may be stored in a milkhouse. Any of the chemicals labeled for routine use in a milkhouse must be stored in a manner that precludes contamination of milk and milk handling equipment.

ATCP 65.10(1)(1) General. An adequate supply of potable water shall be supplied under pressure for milkhouse and milking operations. Water used for milkhouse and milking operations, including water used to cool milk in a plate or tubular cooler, shall be potable. Potable water shall comply with the microbiological drinking water standards set forth in s. NR 809.30.

ATCP 65.10(2)(2) Backflow protection; cross-connections. A potable water supply system on a dairy farm shall be designed, constructed, installed, and maintained to prevent contamination of the potable water supply through backflow, backsiphonage, cross-connections, or any other connection to the potable water supply system. An air gap adequate to prevent the back-siphonage or backflow of any liquids shall be maintained between every potable water outlet and the flood rim of the fixture that it supplies, and between the potable water outlet and every other source of potential contamination, unless alternative protection is approved under s. SPS 382.41.

ATCP 65.10(4)(4) Water transported to dairy farm. A person transporting water in containers or tanks to a dairy farm for milkhouse or milking operations shall seal the containers or tanks to prevent contamination. The containers and tanks shall be thoroughly cleaned and sanitized before being filled with potable water for use at the dairy farm. A sanitarily designed, cleaned, and sanitized pump, hose, and fittings shall be used to transfer water from transport containers and tanks to previously cleaned and sanitized storage tanks at the dairy farm so that the water is not contaminated during transfer or by the storage tanks.

ATCP 65.10(5)(5) Water quality testing by dairy plant. A dairy plant operator, including a milk contractor that submits a milk producer license application on behalf of a milk producer and thereby certifies that the milk producer’s dairy farm and milking operations comply with applicable requirements under this chapter, shall do all of the following for each milk producer from whom the dairy plant operator procures milk:

ATCP 65.10(5)(a)(a) Sample the milk producer’s water supply at least once every two years. If the water supply system has more than one well, water from each well shall be sampled. The water sample from each well shall be taken from water before it has flowed into a pressure tank or any water treatment equipment.

ATCP 65.10(5)(b)(b) Sample the milk producer’s water supply whenever the milk producer installs, alters, or repairs the water supply system.

ATCP 65.10(5)(c)(c) Sample any transported water supply used by the milk producer at the point of use, at or before first use and monthly thereafter.
