Sampling and weighing.

 

      RELATES TO: KRS

260.775-260.845, 260.992

      STATUTORY AUTHORITY:

KRS 260.825(1)

      NECESSITY, FUNCTION,

AND CONFORMITY: KRS

260.825(1) authorizes the Director of the Agricultural Experiment Station to

promulgate administrative regulations necessary for the efficient enforcement

of KRS 260.775 to 260.845 regarding milk. This administrative regulation

establishes procedures for milk sampler-weighers for accurately sampling and

weighing milk in farm bulk tanks.

 

      Section 1. Each bulk farm tank is

required to be separately sampled and weighed. If a producer has multiple bulk

farm tanks, samples and weights shall be obtained for each tank and the

information recorded separately in the sampler-weigher’s records.

 

      Section 2. Sampler-weigher Equipment. A

sampler-weigher shall use the following equipment in his sampling and weighing

procedures:

      (1) A sample case shall:

      (a) Be rigidly constructed and insulated

for safe transportation of the samples;

      (b) Have ample space to hold samples;

      (c) Maintain a refrigerant that is needed

to cool and maintain the samples at a temperature range of 0.5-4.40

C (33-400 F);

      (d) Contain a rack or float to keep the

samples in an upright position and to keep the neck and the top of each sample

container above the surface of the cooling medium; and

      (e) Maintain a refrigerant at the level

of the milk in the sample containers.

      (2) Sample containers shall be clean,

dry, and sterile. Sample vials shall have leak-proof caps and may be made of

glass or molded, rigid plastic. Approved plastic bags may also be used. The

sample containers shall hold a minimum of one (1) ounce of milk and provide

sufficient air space for processing the sample in the laboratory;

      (3) A sample dipper or other sampling

device of sanitary construction. The sampling device shall be stored in a

receptacle containing a sanitizing solution. Both the sampling device and the

sanitizing solution shall be approved by the Milk Safety Branch of the Cabinet

for Health Services;

      (4) An accurate dial or digital

thermometer;

      (5) A waterproof, indelible marker to

write information on sample containers;

      (6) A watch to time the agitation of the

milk in the bulk tank prior to sampling;

      (7) An indelible pen to complete the

necessary paperwork; and

      (8) An adequate supply of bulk milk

delivery tickets.

 

      Section 3. Weighing Procedures. When

measuring milk volume in farm bulk tanks with a gauge rod inside the tank or an

external scale plate with gauge tube on the outside of the tank, the milk shall

be motionless. A sampler-weigher shall:

      (1) Use the following procedures for

measuring milk with a gauge rod on the inside of a bulk tank:

      (a) Remove any milk foam from the

measurement area by pushing it aside with the rod;

      (b) Remove any milk residue from the rod

by wiping the rod with a clean, single-service towel. If the milk residue

cannot be removed by this method, rinse the rod in warm (not hot) water and

again wipe the rod with a single-service towel;

      (c) Lower the gauge rod slowly straight

down until it reaches a point approximately one-quarter (1/4) inch above its

base. Hold the rod in this position for a moment and then ease it down until it

seats firmly and naturally in its base;

      (d) Raise the gauge rod and immediately

read it in a well-lighted area at eye level;

      (e) The gauge rod shall be read to the

nearest graduation mark on the rod. If the reading is exactly half-way between

two (2) graduation marks, read to the nearest even mark; and

      (f) Repeat the gauge rod reading until

two (2) readings are in agreement and record the reading.

      (2) Use the following procedures for

measuring milk with an external scale plate and gauge tube on the outside of a

bulk milk tank:

      (a) If milk is in the external scale

plate’s gauge tube, it shall be drained and refilled with cold milk. The tube

shall be clean and dry prior to filling it with milk;

      (b) To fill the gauge tube, open the

outlet valve slowly to prevent foaming of milk as it fills the tube;

      (c) After the milk from the bottom of the

tank fills the tube, read the highest point of the center of the milk’s

meniscus as the measuring point to compare to the scale plate;

      (d) The scale plate shall be read to the

nearest graduation mark. If the reading is exactly half-way between two (2)

graduation marks, read to the nearest even mark; and

      (e) Repeat the scale plate and gauge tube

reading until two (2) readings are in agreement and record the reading.

      (3) Promptly convert the volume reading

of the bulk milk tank to milk weight using the tank’s conversion chart. The

conversion should be repeated until two (2) conversions are in agreement.

Record the milk weight.

      (4) Procedures for weighing farm bulk

milk in tanks that are not equipped with a gauge shall be approved by the

director.

 

      Section 4. Sampler-weigher Records. A

sampler-weigher shall prepare and account for records pertaining to milk he

samples and weighs.

      (1) Sampler-weigher records shall

include;

      (a) Bulk milk delivery tickets;

      (b) Producer barn charts;

      (c) Information recorded on sample containers;

and

      (d) Any other record relating to bulk

milk sampling and weighing activities.

      (2) All records relating to

sampler-weigher’s daily activities shall be legible and written in indelible

ink. Changes or corrections to records shall be made by drawing a single line

through the entry and writing the correction nearby. Any changes or corrections

shall be dated and initialed.

      (3) Bulk milk delivery tickets shall

accompany all loads of milk to milk-receiving stations, transfer stations, and

processors and shall include the following information:

      (a) Identification of the handler;

      (b) Identification of the milk-receiving

station, transfer station, or processor;

      (c) Date of collection;

      (d) Producer identification (and tank

identification if the producer has multiple tanks);

      (e) Time of pickup (including a.m. or

p.m.);

      (f) Temperature of the milk;

      (g) Milk volumetric reading;

      (h) Converted milk weight;

      (i) Any comments related to unusual

circumstances; and

      (j) Sampler-weigher’s signature.

      (4) A sampler-weigher shall record the

following information on producer barn charts for each tank sampled and

weighed:

      (a) Date;

      (b) Time (including a.m. or p.m.);

      (c) Milk temperature;

      (d) Milk volumetric reading;

      (e) Converted milk weight; and

      (f) Sampler-weigher’s signature or

initials.

      (5) If more than one (1) sampler-weigher

samples and weighs producers’ milk for one (1) truckload, each sampler-weigher

shall sign the bulk milk delivery ticket, regardless of who delivers the load

to the milk-receiving station, transfer station, or processor.

 

      Section 5. Sampling Procedures. A

sampler-weigher shall use the following procedures to obtain a representative

sample from a producer’s standard farm bulk tank:

      (1) Each sample container shall be

permanently marked with waterproof, indelible ink and shall be identified with

the following information:

      (a) Producer identification (and tank

identification if the producer has multiple tanks);

      (b) Date;

      (c) Time (including a.m. or p.m.);

      (d) Milk temperature; and

      (e) Sampler-weigher’s initials.

      (2) Milk in the bulk tank shall be

agitated sufficiently to provide a homogenous blend and to obtain a

representative sample. A minimum of five (5) minutes of agitation time is

required for tanks with less than a 1000 gallon capacity. Tanks with a 1000

gallon capacity or larger shall be agitated a minimum of ten (10) minutes;

      (3) To eliminate moisture and sanitizing

solutions, the sampling device shall be rinsed with milk at least twice prior

to taking samples;

      (4) The milk shall be transferred from

the sampling device to the sterile sample container away from the opening of

the farm bulk tank. The container shall be filled to approximately

three-fourths (3/4) full or to the container’s "fill line." Enough

air space shall be left in the container to allow the sample to be adequately

mixed at the laboratory. After the milk has been transferred to the sample

container, the container shall be tightly sealed and immediately placed in the

sample case with appropriate refrigerant;

      (5) At the time of sampling the first

bulk milk tank on the sampler-weigher’s route, an additional sample shall be

collected for temperature determination. This sample’s container shall be

identified with the information outlined in subsection (1) of this section and

with adequate information to identify the sample as the temperature control;

      (6) Any additional or special samples

obtained on the sampler-weigher’s route shall be clearly and specifically

identified with waterproof, indelible markings stating the purpose of the

sample; and

      (7) Sampling procedures for nonstandard

or sealed farm bulk milk tanks shall be approved by the director.

      (8) Milk samples shall be under a

sampler-weigher’s immediate care at all times until the samples are delivered to

the milk-receiving station, transfer station, or processor.

 

      Section 6. Load Sample. A sampler-weigher

shall obtain a load sample from the tank on his truck immediately after the

last producer’s milk is pumped into the truck’s tank.

      (1) The load sample shall be taken from

the porthole at the top of the tank on the truck using a sanitized sampling

device. Care shall be taken to prevent any foreign material from entering the

porthole. The load-sample container shall be identified with the following information:

      (a) Adequate information to identify the

sample as the load-sample;

      (b) Date;

      (c) Time (including a.m. or p.m.);

      (d) Sampler-weigher’s initials; and

      (e) The milk truck’s assigned tanker

number.

      (2) The load sample is to be used for

comparisons of the load sample and individual producer’s samples for the

purpose of grading and evaluation of the sampler-weigher’s competency in

sampling; and

      (3) The load sample is to be taken by all

bulk sampler-weighers in addition to, not in lieu of, any other load samples

required by the milk handler, transfer station, receiving station, or

processor.

 

      Section 7. Sample Set. A sample for each

producer bulk milk tank, a temperature control sample, and a load sample shall

accompany each load of milk to its final receiving station, transfer station,

or processor. A sampler-weigher may need to obtain multiple samples for his

bulk milk route to meet this requirement.

 

      Section 8. Milk Sample Transfer

Procedures. To expedite the transport of samples to the appropriate laboratory,

a sampler-weigher shall follow these procedures:

      (1) For bulk milk deliveries to locations

where producers’ milk samples are routinely transported from the receiving

station, transfer station, or processor to the appropriate laboratory; a sampler-weigher

shall properly place his samples in the location’s sample storage refrigerator

or refrigerated sample storage case after the bulk load of milk has been

determined to be acceptable; or

      (2) For bulk delivery when producer’s

milk samples are not routinely transported from the receiving station, transfer

station, or processor to the appropriate laboratory, a sampler-weigher shall

follow written sample transfer procedures established by the licensed handler(s)

who issues payments to producers on the sampler-weigher’s route(s). Written

sample transfer procedures shall be approved by the director. (AES-CL 13; 1 Ky.R. 1234; eff. 7-2-75; Am. 11
