Chapter 3

SECTION 6 and 7

1. The universal sampling program - This refers to the responsibility of
the milk hauler to collect a representative sample of milk from each
farm bulk tank prior to transferring the milk from the farm bulk tank. If
the hauler is properly licensed and/or permitted these samples may
be used as official samples as designated by the regulatory agency. If the
universal samples are used as official samples, a system of randomization of
the selected samples must be used by the regulatory agency to assure validity
of the sampling program.

2. During any consecutive six month period at least four samples of raw
milk shall be collected from each Grade “A” dairy farm. Two samples
may be collected in one month and be counted for minimum frequency
purposes as long as the two sampling dates are separated by at least 20
days. The results of all officially collected samples shall be used for
determination of compliance with the established chemical, bacterial,
and temperature standards.

3. Samples must be taken while in possession of the producer, i.e., either
from the farm bulk milk tank or producer owned and operated milk tank
truck.

4. Samples shall be analyzed for:

BACTERIAL COUNTS DRUG RESIDUES
SOMATIC CELL COUNTS COOLING TEMPERATURES

(Commingled milk may be used for testing of pesticides; however the commingled milk sampled
must represent all producers in the sample.)
