ATCP 65.78(3)(b)(b) If a weigh tank is not large enough to accommodate a producer’s entire milk shipment, so that multiple weighings are needed, the dairy plant operator shall divide the shipment as evenly as possible between weighings and collect a sample from each weighing. The samples shall be of equal volume and shall be combined to form a single sample representing the entire shipment from the producer. The dairy plant operator may not split the contents of any single can of milk between weighings, but shall include all of the contents of that can in the same weighing.
ATCP 65.78(4)(4)Composite samples.
ATCP 65.78(4)(a)(a) A dairy plant operator may use a composite sample to perform a Babcock test for milkfat, but may not perform any other milk quality test on a composite sample except with the division’s written authorization. A composite sample shall be compiled according to this subsection.
ATCP 65.78(4)(b)(b) A composite sample shall include a representative sample of milk from each of 2 or more milk shipments represented by the composite sample. No composite sample may include milk from more than 16 milk shipments. Each component sample included in the composite sample shall have the same volume and shall include at least 10 ml. of milk. A composite sample shall include at least 150 ml. of milk.
ATCP 65.78(4)(c)(c) A composite sample container shall have a capacity of at least 240 ml. The composite sample container shall include an effective permanent closure that is attached to the container. The composite sample container shall be marked to identify the producer and the milk shipments represented in the composite sample.
ATCP 65.78(4)(d)(d) A composite sample representing a producer’s bulk milk shipments shall be compiled from fresh milk samples collected from those shipments under s. ATCP 82.12. On the same day that a producer’s bulk milk shipment is received by the dairy plant operator, or by 12:00 noon of the following day, the dairy plant operator shall transfer, to the composite sample, at least 10 ml. of milk from the sample collected from that milk shipment under s. ATCP 82.12.
ATCP 65.78(4)(e)(e) A composite sample representing a producer’s shipments of milk in cans shall be compiled from milk samples collected from those shipments according to sub. (3).
ATCP 65.78(4)(f)(f) A dairy plant operator shall preserve a composite sample by adding potassium dichromate, or another preservative approved by the division, to the composite sample. Not less than 100 mg., nor more than 190 mg. of potassium dichromate may be used in each composite sample to obtain a concentration of 20 mg. per 30 ml. of milk in the completed sample.
ATCP 65.78 NoteNote: Potassium dichromate is available in tablets containing 40 mg. of active ingredient per tablet. The use of these tablets at the rate of one tablet per 2 fl. oz. of milk in a completed composite sample is equivalent to the concentration specified under par. (f). Labeling requirements and limitations on the disposal of milk samples preserved with potassium dichromate are contained in s. ATCP 30.15 (2) (b).
